What we know about long COVID — from brain fog to physical fatigue

March 13, 2024 • "Long COVID has affected every part of my life," said Virginia resident Rachel Beale said at a recent Senate hearing. "I wake up every day feeling tired, nauseous and dizzy. I immediately start planning when I can lay down again." Beale is far from alone. Many of her experiences have been echoed by others dealing with long COVID. It's a constellation of debilitating symptoms that range from brain fog and intense physical fatigue to depression and anxiety. But there's new, promising research that sheds light onto some symptoms. NPR health correspondent Will Stone talks with Short Wave host Regina G. Barber about the state of long COVID research — what we know, what we don't and when we can expect treatments or even cures for it. Have more COVID questions you want us to cover?

The "shocking" tactic electric fish use to collectively sense the world

March 8, 2024 • Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals, which Sawtell hopes will eventually help neuroscientists better understand how the brain filters sensory information about the outside world. As Sawtell has studied these electric critters, he's had a lingering question: why do they always seem to organize themselves in a particular orientation. At first, he couldn't figure out why, but a new study released this week in Nature may have an answer: the fish are creating an electrical network larger than any field a single fish can muster alone, and providing collective knowledge about potential dangers in the surrounding water.

The Voyager 1 spacecraft has a big glitch. Now, NASA must figure out how to fix it

March 6, 2024 • The Voyager 1 space probe is the farthest human-made object in space. It launched in 1977 with a golden record on board that carried assorted sounds of our home planet: greetings in many different languages, dogs barking, and the sound of two people kissing, to name but a few examples. The idea with this record was that someday, Voyager 1 might be our emissary to alien life – an audible time capsule of Earth's beings. Since its launch, it also managed to complete missions to Jupiter and Saturn. In 2012, it crossed into interstellar space.

In light of the solar maximum, a look at the biggest solar storm in recorded history

February 21, 2024 • We are at the height of the Sun's activity in its eleven year cycle, known to astronomers as the solar maximum. This means that over the next several months there's going to be a lot of solar activity. It's got us thinking back to 1859. That's when astronomer Richard Carrington was studying the Sun when he witnessed the most intense geomagnetic storm recorded in history. The storm, triggered by a giant solar flare, sent brilliant auroral displays across the globe causing electrical sparking and fires in telegraph stations. This encore episode, Regina talks to solar physicist Dr. Samaiyah Farid about what's now known as the Carrington event and about what may happen the next time a massive solar storm hits Earth.

One woolly mammoth's journey at the end of the Ice Age

February 19, 2024 • Lately, paleoecologist Audrey Rowe has been a bit preoccupied with a girl named Elma. That's because Elma is ... a woolly mammoth. And 14,000 years ago, when Elma was alive, her habitat in interior Alaska was rapidly changing. The Ice Age was coming to a close and human hunters were starting early settlements. Which leads to an intriguing question: Who, or what , killed her? In the search for answers, Audrey traces Elma's life and journey through — get this — a single tusk. Today, she shares her insights on what the mammoth extinction from thousands of years ago can teach us about megafauna extinctions today with guest host Nate Rott .

Clownfish might be counting their potential enemies' stripes

February 9, 2024 • At least, that's what a group of researchers at the Okinawa Institute of Science and Technology Graduate University thinks. The team recently published a study in the journal Experimental Biology suggesting that Amphiphrion ocellaris , or clown anemonefish, may be counting. Specifically, the authors think the fish may be looking at the number of vertical white stripes on each other as well as other anemonefish as a way to identify their own species. Not only that — the researchers think that the fish are noticing the minutiae of other anemonefish's looks because of some fishy marine geopolitics.

Why wolves are thriving in this radioactive zone

February 5, 2024 • In 1986 the Chernobyl nuclear power plant exploded, releasing radioactive material into northern Ukraine and Belarus. It was the most serious nuclear accident in history. Over one hundred thousand people were evacuated from the surrounding area. But local gray wolves never left — and their population has grown over the years. It's seven times denser than populations in protected lands elsewhere in Belarus. This fact has led scientists to wonder whether the wolves are genetically either resistant or resilient to cancer — or if the wolves are simply thriving because humans aren't interfering with them.

1000+ FREE Research Topics & Ideas

If you’re at the start of your research journey and are trying to figure out which research topic you want to focus on, you’ve come to the right place. Select your area of interest below to view a comprehensive collection of potential research ideas.

Research Topic FAQs

What (exactly) is a research topic.

A research topic is the subject of a research project or study – for example, a dissertation or thesis. A research topic typically takes the form of a problem to be solved, or a question to be answered.

A good research topic should be specific enough to allow for focused research and analysis. For example, if you are interested in studying the effects of climate change on agriculture, your research topic could focus on how rising temperatures have impacted crop yields in certain regions over time.

To learn more about the basics of developing a research topic, consider our free research topic ideation webinar.

What constitutes a good research topic?

A strong research topic comprises three important qualities : originality, value and feasibility.

• Originality – a good topic explores an original area or takes a novel angle on an existing area of study.
• Value – a strong research topic provides value and makes a contribution, either academically or practically.
• Feasibility – a good research topic needs to be practical and manageable, given the resource constraints you face.

To learn more about what makes for a high-quality research topic, check out this post .

What's the difference between a research topic and research problem?

A research topic and a research problem are two distinct concepts that are often confused. A research topic is a broader label that indicates the focus of the study , while a research problem is an issue or gap in knowledge within the broader field that needs to be addressed.

To illustrate this distinction, consider a student who has chosen “teenage pregnancy in the United Kingdom” as their research topic. This research topic could encompass any number of issues related to teenage pregnancy such as causes, prevention strategies, health outcomes for mothers and babies, etc.

Within this broad category (the research topic) lies potential areas of inquiry that can be explored further – these become the research problems . For example:

• What factors contribute to higher rates of teenage pregnancy in certain communities?
• How do different types of parenting styles affect teen pregnancy rates?
• What interventions have been successful in reducing teenage pregnancies?

Simply put, a key difference between a research topic and a research problem is scope ; the research topic provides an umbrella under which multiple questions can be asked, while the research problem focuses on one specific question or set of questions within that larger context.

How can I find potential research topics for my project?

There are many steps involved in the process of finding and choosing a high-quality research topic for a dissertation or thesis. We cover these steps in detail in this video (also accessible below).

How can I find quality sources for my research topic?

Finding quality sources is an essential step in the topic ideation process. To do this, you should start by researching scholarly journals, books, and other academic publications related to your topic. These sources can provide reliable information on a wide range of topics. Additionally, they may contain data or statistics that can help support your argument or conclusions.

Identifying Relevant Sources

When searching for relevant sources, it’s important to look beyond just published material; try using online databases such as Google Scholar or JSTOR to find articles from reputable journals that have been peer-reviewed by experts in the field.

You can also use search engines like Google or Bing to locate websites with useful information about your topic. However, be sure to evaluate any website before citing it as a source—look for evidence of authorship (such as an “About Us” page) and make sure the content is up-to-date and accurate before relying on it.

Evaluating Sources

Once you’ve identified potential sources for your research project, take some time to evaluate them thoroughly before deciding which ones will best serve your purpose. Consider factors such as author credibility (are they an expert in their field?), publication date (is the source current?), objectivity (does the author present both sides of an issue?) and relevance (how closely does this source relate to my specific topic?).

By researching the current literature on your topic, you can identify potential sources that will help to provide quality information. Once you’ve identified these sources, it’s time to look for a gap in the research and determine what new knowledge could be gained from further study.

How can I find a good research gap?

Finding a strong gap in the literature is an essential step when looking for potential research topics. We explain what research gaps are and how to find them in this post.

How should I evaluate potential research topics/ideas?

When evaluating potential research topics, it is important to consider the factors that make for a strong topic (we discussed these earlier). Specifically:

• Originality
• Feasibility

So, when you have a list of potential topics or ideas, assess each of them in terms of these three criteria. A good topic should take a unique angle, provide value (either to academia or practitioners), and be practical enough for you to pull off, given your limited resources.

Finally, you should also assess whether this project could lead to potential career opportunities such as internships or job offers down the line. Make sure that you are researching something that is relevant enough so that it can benefit your professional development in some way. Additionally, consider how each research topic aligns with your career goals and interests; researching something that you are passionate about can help keep motivation high throughout the process.

How can I assess the feasibility of a research topic?

When evaluating the feasibility and practicality of a research topic, it is important to consider several factors.

First, you should assess whether or not the research topic is within your area of competence. Of course, when you start out, you are not expected to be the world’s leading expert, but do should at least have some foundational knowledge.

Time commitment

When considering a research topic, you should think about how much time will be required for completion. Depending on your field of study, some topics may require more time than others due to their complexity or scope.

Additionally, if you plan on collaborating with other researchers or institutions in order to complete your project, additional considerations must be taken into account such as coordinating schedules and ensuring that all parties involved have adequate resources available.

Resources needed

It’s also critically important to consider what type of resources are necessary in order to conduct the research successfully. This includes physical materials such as lab equipment and chemicals but can also include intangible items like access to certain databases or software programs which may be necessary depending on the nature of your work. Additionally, if there are costs associated with obtaining these materials then this must also be factored into your evaluation process.

Potential risks

It’s important to consider the inherent potential risks for each potential research topic. These can include ethical risks (challenges getting ethical approval), data risks (not being able to access the data you’ll need), technical risks relating to the equipment you’ll use and funding risks (not securing the necessary financial back to undertake the research).

Sat / act prep online guides and tips, 113 great research paper topics.

General Education

One of the hardest parts of writing a research paper can be just finding a good topic to write about. Fortunately we've done the hard work for you and have compiled a list of 113 interesting research paper topics. They've been organized into ten categories and cover a wide range of subjects so you can easily find the best topic for you.

In addition to the list of good research topics, we've included advice on what makes a good research paper topic and how you can use your topic to start writing a great paper.

What Makes a Good Research Paper Topic?

Not all research paper topics are created equal, and you want to make sure you choose a great topic before you start writing. Below are the three most important factors to consider to make sure you choose the best research paper topics.

#1: It's Something You're Interested In

A paper is always easier to write if you're interested in the topic, and you'll be more motivated to do in-depth research and write a paper that really covers the entire subject. Even if a certain research paper topic is getting a lot of buzz right now or other people seem interested in writing about it, don't feel tempted to make it your topic unless you genuinely have some sort of interest in it as well.

#2: There's Enough Information to Write a Paper

Even if you come up with the absolute best research paper topic and you're so excited to write about it, you won't be able to produce a good paper if there isn't enough research about the topic. This can happen for very specific or specialized topics, as well as topics that are too new to have enough research done on them at the moment. Easy research paper topics will always be topics with enough information to write a full-length paper.

Trying to write a research paper on a topic that doesn't have much research on it is incredibly hard, so before you decide on a topic, do a bit of preliminary searching and make sure you'll have all the information you need to write your paper.

#3: It Fits Your Teacher's Guidelines

Don't get so carried away looking at lists of research paper topics that you forget any requirements or restrictions your teacher may have put on research topic ideas. If you're writing a research paper on a health-related topic, deciding to write about the impact of rap on the music scene probably won't be allowed, but there may be some sort of leeway. For example, if you're really interested in current events but your teacher wants you to write a research paper on a history topic, you may be able to choose a topic that fits both categories, like exploring the relationship between the US and North Korea. No matter what, always get your research paper topic approved by your teacher first before you begin writing.

113 Good Research Paper Topics

Below are 113 good research topics to help you get you started on your paper. We've organized them into ten categories to make it easier to find the type of research paper topics you're looking for.

How to Write a Great Research Paper

Even great research paper topics won't give you a great research paper if you don't hone your topic before and during the writing process. Follow these three tips to turn good research paper topics into great papers.

#1: Figure Out Your Thesis Early

Before you start writing a single word of your paper, you first need to know what your thesis will be. Your thesis is a statement that explains what you intend to prove/show in your paper. Every sentence in your research paper will relate back to your thesis, so you don't want to start writing without it!

As some examples, if you're writing a research paper on if students learn better in same-sex classrooms, your thesis might be "Research has shown that elementary-age students in same-sex classrooms score higher on standardized tests and report feeling more comfortable in the classroom."

If you're writing a paper on the causes of the Civil War, your thesis might be "While the dispute between the North and South over slavery is the most well-known cause of the Civil War, other key causes include differences in the economies of the North and South, states' rights, and territorial expansion."

#2: Back Every Statement Up With Research

Remember, this is a research paper you're writing, so you'll need to use lots of research to make your points. Every statement you give must be backed up with research, properly cited the way your teacher requested. You're allowed to include opinions of your own, but they must also be supported by the research you give.

#3: Do Your Research Before You Begin Writing

You don't want to start writing your research paper and then learn that there isn't enough research to back up the points you're making, or, even worse, that the research contradicts the points you're trying to make!

Get most of your research on your good research topics done before you begin writing. Then use the research you've collected to create a rough outline of what your paper will cover and the key points you're going to make. This will help keep your paper clear and organized, and it'll ensure you have enough research to produce a strong paper.

Research Topics

10 most viewed research topics in 2023.

This year, researchers explored a wide range of topics, including:

cancer combinational immunotherapy

COVID-19 research

the physiology of breathing during exercise

and the future of animal experimentation

With over 1.8 million views, the following Research Topics sought answers to your biggest research questions from 2023.

1 | Towards a New 3Rs Era in Experimental Research

36 articles │ 177,000 views

With the persisting need of animal experimentation for fundamental and applied research, the relevance and importance of the 3Rs Principle cannot be ignored. The 3Rs Principle of Replace, Reduce, Refine provides an essential framework for more humane animal experimentation in research.

This multi-disciplinary research review is a pan-European initiative supported by all EU 3R centers exploring the 3Rs Principle advances, challenges, and opportunities. The Research Topic draws upon multiple scientific disciplines, including biomedical, veterinary, biostatistical, biotechnology, and computer science, as well as perspectives from education, social, political, and ethical research in the 3Rs field.

2 | Combinational Immunotherapy of Cancer: Novel Targets, Mechanisms, and Strategies

84 articles │ 176,000 views

Cancer immunotherapy, including immune checkpoint inhibitors (ICIs) and chimeric antigen receptor T-cell (CAR-T) therapy, has revolutionized the paradigm in cancer treatment. However, the clinical outcome of immunotherapy varies considerably among patients, and only a minority of patients achieve long-term clinical benefits.

This Research Topic gathers novel insights into the cancer immunity mechanisms, novel therapeutic targets, and effective combinational strategies of cancer immunotherapies. It also addresses the fundamental understanding of mechanisms underlying cancer immunotherapy and the therapeutic potential of novel combinational therapy.

3 | Breathing in Sport and Exercise: Physiology, Pathophysiology and Applications

37 articles │ 180,000 views

The respiratory system has long been considered overbuilt for exercise as it is usually not the limiting factor for maximal oxygen uptake. However, growing evidence suggests that ventilatory variables such as respiratory frequency (ƒR) especially are closely associated with perceived exertion and exercise tolerance in different populations and exercise conditions, with important implications for endurance physiology and performance.

This Research Topic advances our understanding of the physiology and pathophysiology of breathing during exercise to advance the field of respiratory monitoring in applied settings. It also bridges the gap between the physiology/pathophysiology of breathing and respiratory monitoring.

4 | Multidisciplinary COVID-19 research

91 articles │ 148,000 views

The outbreak of Coronavirus Disease 2019 (COVID-19) has seriously impacted mental and physical health worldwide. New and emerging solutions to global health threats posed by COVID-19 are urgently needed.

This second volume brings together scientists and clinicians in artificial intelligence, mathematics and statistics, neural science, neurorobotics, social sciences, computational biology, medical health care, psychiatry, and psychology to promote COVID-19 research and stimulate collaboration between researchers in these diverse fields.

5 | Sustainable Career Development in the Turbulent, Boundaryless and Internet Age

40 articles │ 115,000 views

Government’s social policies, such as school-to-work transitional regulations, and the extended retirement age, suggest that people today may face a different labor market situation, compared to other generations.

Career sustainability is a key issue, and it is particularly the case for vulnerable groups, such as the underemployed, (re) employment of laidoff workers, and those who strive to balance between work and personal life. Therefore, this research topic investigates the antecedents and outcomes of career sustainability in different social contexts.

6 | The Nobel collection, Volume 2 - Frontiers for Young Minds

10 articles │ 673,000 views

This second Volume of our unique Nobel Collection brings you more articles by Nobel Prize winners written specifically for young minds. These amazing research leaders explain their ground-breaking discoveries and how they achieved them, and also share their thoughts on making a career path in science with advice for becoming a successful researcher and having a happy life.

7 | Psychiatrization of society

17 articles │104,000 views

Worldwide, there have been consistently rising incidences of people classified as mentally ill, paired with increasing mental healthcare service utilization over the last decades. This process can be described as the psychiatrization of society.

Individuals or groups might well benefit from aspects of psychiatrization. Yet psychiatrization can be potentially harmful to individuals and to public healthcare, through overdiagnosis and overtreatment, the psychological burden of being labeled, and, in the Global North, exploding costs to meet the needs of the ‘worried well’.

This article collection seeks to theoretically and empirically assesses the causes, mechanisms, and effects of psychiatrization, as well to understand, prevent, and manage its negative aspects.

8 | Patterns, Functions, and Processes of Alpine Grassland Ecosystems under Global Change

76 articles │ 102,000 views

Alpine grassland ecosystems provide important ecological services and functions, such as biodiversity conservation, carbon storage, and water resource regulation, and critical ecosystem services, such as pastoral production, cultural inheritance, tourism, and recreation. In recent decades, some of these regions have experienced rapid climatic warming and changes in precipitation regimes.

This Research Topic elucidates the patterns, functions, processes, and mechanisms of alpine grassland ecosystems responding to changing environments. The goal is to influence the development of adaptive management practices for alpine grassland ecosystems under future environmental change.

9 | Abiotic Stress-Induced Responses and Tolerance Mechanisms in Plants : Molecular, Cellular, Physiological and Biochemical Levels

59 articles │ 99,000 views

In nature, plants are constantly facing adverse environmental conditions, including abiotic stresses caused by extreme low and high temperature, salinity, drought, flood, heavy metal toxicity and oxidative stress. These stresses, especially drought, salinity, and high temperature, are the major causes of crop loss around the globe.

This Research Topic advances our understanding of the fundamental processes, stress signaling, and adaptation mechanisms that develop in plants in response to various abiotic stresses.

10 | Serving Vulnerable and Marginalized Populations in Social and Educational Contexts

26 articles │ 97,000 views

There is evidence that the global COVID-19 crisis is exacerbating existing inequalities and marginalization of vulnerable groups. These multi-sectoral and intersecting challenges require multi- and interdisciplinary interventions to inform inclusive responses.

This Research Topic addresses the educational and socio-emotional needs of marginalized, vulnerable, at-risk, and exceptional learners during and after crises. It also addresses the psychological, educational, sociological, health, gender, cultural, and economic aspects of vulnerable and marginalized children and adolescents in developed and developing countries.

The 10 Most Popular Articles in 2022 (So Far)

Managers are seeking ways to improve employee well-being and build a strong workplace culture.

• Workplace, Teams, & Culture
• Talent Management
• Organizational Behavior

Year three of a global pandemic. A war in Ukraine. Inflation in the U.S. at a 40-year high. Small talk around the watercooler (mainly the virtual one, nowadays) certainly feels heavier than it used to.

Recent Gallup data indicates that in 2022, companies and managers remain challenged by the task of raising employee engagement to pre-pandemic levels. Nearly half of global workers (44%) surveyed reported feeling “a lot” of stress in the previous day. The Great Resignation has demonstrated the power of employees to vote with their feet, and a resurgence of the labor movement in the U.S. has put pressure on even top-tier companies to improve working conditions.

Companies that have thrived amid the pandemic and worker reshuffling have focused on worker well-being from the start. Unfortunately, for many employees across the globe, this may be the exception rather than the norm. As Gallup’s Jon Clifton put it, “Improving life at work isn’t rocket science, but the world is closer to colonizing Mars than it is to fixing the world’s broken workplaces.”

To begin to fix these issues, managers must focus on two areas in particular: leadership and culture. In the first months of the year, many MIT SMR readers turned their attention to articles focused on workplace culture, talent management, and employee retention.

With many companies now adopting permanent remote and hybrid work policies, other popular articles include data-driven approaches to managing well-being on virtual teams — from scheduling meeting-free days to creating systems for supporting mental health.

The following are the 10 most popular articles of the year so far. We hope they will continue to help managers who are looking to support employee engagement and build thriving workplaces.

#1 Toxic Culture Is Driving the Great Resignation

Donald sull, charles sull, and ben zweig.

In this article, the authors discuss the top five predictors of employee turnover uncovered by their analysis of attrition data during the Great Resignation and share four actions that managers can take in the short term to improve employee satisfaction.

#2 Top Performers Have a Superpower: Happiness

Paul b. lester, ed diener, and martin seligman.

Research has found that happiness, a sense of well-being, and an optimistic outlook are powerful predictors of how well an employee will perform. Managers who consciously promote employee well-being and take steps to eliminate toxic leadership in their business units will reap the benefits.

#3 The Surprising Impact of Meeting-Free Days

Ben laker, vijay pereira, pawan budhwar, and ashish malik.

Spending too much time in meetings can detract from effective collaboration, derail workers during their most productive hours, and interrupt people’s train of thought. No-meeting policies permit team members to excel without breaking their momentum, but specific plans must be tailored to each unique organizational context to maximize the benefits. The authors suggest several ways to deploy a no-meeting policy or adjust an existing one.

#4 Orchestrating Workforce Ecosystems

Elizabeth j. altman, david kiron, robin jones, and jeff schwartz.

Research conducted by MIT SMR and Deloitte examines the challenges companies and managers face in leading and coordinating workforces that increasingly rely on external contributors.

#5 Why Every Leader Needs to Worry About Toxic Culture

Donald sull, charles sull, william cipolli, and caio brighenti.

According to research, the five most common elements of toxic workplace cultures — being disrespectful, noninclusive, unethical, cutthroat, and abusive — contribute the most to employee attrition and can damage company reputation. Being aware of these elements and understanding how they spread can help employers prevent and address them.

#6 Building the Cognitive Budget for Your Most Effective Mind

Jordan birnbaum.

There’s a limit to how much mental energy is available to us on any given day, so it’s essential that we spend it deliberately and thoughtfully. This article details the process of creating a cognitive budget, using techniques from positive psychology, cognitive behavioral therapy, and behavioral economics.

#7 Stop Telling Employees to Be Resilient

Liz fosslien and mollie west duffy.

When it comes to leadership, there’s a difference between demanding that employees be mentally tough and actually helping them take care of their mental health. The authors suggest five actions leaders can take to create a workplace that supports employees and fosters resilience.

#8 Effective Leaders Decide About Deciding

Nancy duarte.

Categorizing decisions by riskiness and urgency helps clarify when employees should move autonomously and when they should pull leaders into decision-making.

Related Articles

#9 leading change means changing how you lead, b. tom hunsaker and jonathan knowles.

Adapting your leadership approach is necessary for achieving the change your organization requires. The authors discuss three tasks — drawing the map, establishing the mindset, and communicating the message — that are essential to becoming a contextually effective leader.

#10 How Well-Designed Work Makes Us Smarter

Sharon k. parker and gwenith g. fisher.

Work that permits autonomy and demands problem-solving can bolster employees’ cognitive skills and ongoing learning. This article looks at how organizations and managers can use good work design to strengthen their workforce’s ability to adapt to new processes, tools, and roles.

New research suggests that our universe has no dark matter

by Bernard Rizk, University of Ottawa

The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this.

A study, published today in The Astrophysical Journal , challenges the current model of the universe by showing that, in fact, it has no room for dark matter.

In cosmology , the term "dark matter" describes all that appears not to interact with light or the electromagnetic field , or that can only be explained through gravitational force . We can't see it, nor do we know what it's made of, but it helps us understand how galaxies, planets and stars behave.

Rajendra Gupta, a physics professor at the Faculty of Science, used a combination of the covarying coupling constants (CCC) and "tired light" (TL) theories (the CCC+TL model) to reach this conclusion.

This model combines two ideas—about how the forces of nature decrease over cosmic time and about light losing energy when it travels a long distance. It's been tested and has been shown to match up with several observations, such as about how galaxies are spread out and how light from the early universe has evolved.

This discovery challenges the prevailing understanding of the universe, which suggests that roughly 27% of it is composed of dark matter and less than 5% of ordinary matter , remaining being the dark energy.

Challenging the need for dark matter in the universe

"The study's findings confirm that our previous work ("JWST early universe observations and ΛCDM cosmology") about the age of the universe being 26.7 billion years has allowed us to discover that the universe does not require dark matter to exist," explains Gupta.

"In standard cosmology, the accelerated expansion of the universe is said to be caused by dark energy but is in fact due to the weakening forces of nature as it expands, not due to dark energy ."

"Redshifts" refer to when light is shifted toward the red part of the spectrum. The researcher analyzed data from recent papers on the distribution of galaxies at low redshifts and the angular size of the sound horizon in the literature at high redshift.

"There are several papers that question the existence of dark matter, but mine is the first one, to my knowledge, that eliminates its cosmological existence while being consistent with key cosmological observations that we have had time to confirm," says Gupta.

By challenging the need for dark matter in the universe and providing evidence for a new cosmological model, this study opens up new avenues for exploring the fundamental properties of the universe.

A generative AI reset: Rewiring to turn potential into value in 2024

It’s time for a generative AI (gen AI) reset. The initial enthusiasm and flurry of activity in 2023 is giving way to second thoughts and recalibrations as companies realize that capturing gen AI’s enormous potential value is harder than expected .

With 2024 shaping up to be the year for gen AI to prove its value, companies should keep in mind the hard lessons learned with digital and AI transformations: competitive advantage comes from building organizational and technological capabilities to broadly innovate, deploy, and improve solutions at scale—in effect, rewiring the business  for distributed digital and AI innovation.

About QuantumBlack, AI by McKinsey

QuantumBlack, McKinsey’s AI arm, helps companies transform using the power of technology, technical expertise, and industry experts. With thousands of practitioners at QuantumBlack (data engineers, data scientists, product managers, designers, and software engineers) and McKinsey (industry and domain experts), we are working to solve the world’s most important AI challenges. QuantumBlack Labs is our center of technology development and client innovation, which has been driving cutting-edge advancements and developments in AI through locations across the globe.

Companies looking to score early wins with gen AI should move quickly. But those hoping that gen AI offers a shortcut past the tough—and necessary—organizational surgery are likely to meet with disappointing results. Launching pilots is (relatively) easy; getting pilots to scale and create meaningful value is hard because they require a broad set of changes to the way work actually gets done.

Let’s briefly look at what this has meant for one Pacific region telecommunications company. The company hired a chief data and AI officer with a mandate to “enable the organization to create value with data and AI.” The chief data and AI officer worked with the business to develop the strategic vision and implement the road map for the use cases. After a scan of domains (that is, customer journeys or functions) and use case opportunities across the enterprise, leadership prioritized the home-servicing/maintenance domain to pilot and then scale as part of a larger sequencing of initiatives. They targeted, in particular, the development of a gen AI tool to help dispatchers and service operators better predict the types of calls and parts needed when servicing homes.

Leadership put in place cross-functional product teams with shared objectives and incentives to build the gen AI tool. As part of an effort to upskill the entire enterprise to better work with data and gen AI tools, they also set up a data and AI academy, which the dispatchers and service operators enrolled in as part of their training. To provide the technology and data underpinnings for gen AI, the chief data and AI officer also selected a large language model (LLM) and cloud provider that could meet the needs of the domain as well as serve other parts of the enterprise. The chief data and AI officer also oversaw the implementation of a data architecture so that the clean and reliable data (including service histories and inventory databases) needed to build the gen AI tool could be delivered quickly and responsibly.

Our book Rewired: The McKinsey Guide to Outcompeting in the Age of Digital and AI (Wiley, June 2023) provides a detailed manual on the six capabilities needed to deliver the kind of broad change that harnesses digital and AI technology. In this article, we will explore how to extend each of those capabilities to implement a successful gen AI program at scale. While recognizing that these are still early days and that there is much more to learn, our experience has shown that breaking open the gen AI opportunity requires companies to rewire how they work in the following ways.

Figure out where gen AI copilots can give you a real competitive advantage

The broad excitement around gen AI and its relative ease of use has led to a burst of experimentation across organizations. Most of these initiatives, however, won’t generate a competitive advantage. One bank, for example, bought tens of thousands of GitHub Copilot licenses, but since it didn’t have a clear sense of how to work with the technology, progress was slow. Another unfocused effort we often see is when companies move to incorporate gen AI into their customer service capabilities. Customer service is a commodity capability, not part of the core business, for most companies. While gen AI might help with productivity in such cases, it won’t create a competitive advantage.

To create competitive advantage, companies should first understand the difference between being a “taker” (a user of available tools, often via APIs and subscription services), a “shaper” (an integrator of available models with proprietary data), and a “maker” (a builder of LLMs). For now, the maker approach is too expensive for most companies, so the sweet spot for businesses is implementing a taker model for productivity improvements while building shaper applications for competitive advantage.

Much of gen AI’s near-term value is closely tied to its ability to help people do their current jobs better. In this way, gen AI tools act as copilots that work side by side with an employee, creating an initial block of code that a developer can adapt, for example, or drafting a requisition order for a new part that a maintenance worker in the field can review and submit (see sidebar “Copilot examples across three generative AI archetypes”). This means companies should be focusing on where copilot technology can have the biggest impact on their priority programs.

Copilot examples across three generative AI archetypes

• “Taker” copilots help real estate customers sift through property options and find the most promising one, write code for a developer, and summarize investor transcripts.
• “Shaper” copilots provide recommendations to sales reps for upselling customers by connecting generative AI tools to customer relationship management systems, financial systems, and customer behavior histories; create virtual assistants to personalize treatments for patients; and recommend solutions for maintenance workers based on historical data.
• “Maker” copilots are foundation models that lab scientists at pharmaceutical companies can use to find and test new and better drugs more quickly.

Some industrial companies, for example, have identified maintenance as a critical domain for their business. Reviewing maintenance reports and spending time with workers on the front lines can help determine where a gen AI copilot could make a big difference, such as in identifying issues with equipment failures quickly and early on. A gen AI copilot can also help identify root causes of truck breakdowns and recommend resolutions much more quickly than usual, as well as act as an ongoing source for best practices or standard operating procedures.

The challenge with copilots is figuring out how to generate revenue from increased productivity. In the case of customer service centers, for example, companies can stop recruiting new agents and use attrition to potentially achieve real financial gains. Defining the plans for how to generate revenue from the increased productivity up front, therefore, is crucial to capturing the value.

Upskill the talent you have but be clear about the gen-AI-specific skills you need

By now, most companies have a decent understanding of the technical gen AI skills they need, such as model fine-tuning, vector database administration, prompt engineering, and context engineering. In many cases, these are skills that you can train your existing workforce to develop. Those with existing AI and machine learning (ML) capabilities have a strong head start. Data engineers, for example, can learn multimodal processing and vector database management, MLOps (ML operations) engineers can extend their skills to LLMOps (LLM operations), and data scientists can develop prompt engineering, bias detection, and fine-tuning skills.

A sample of new generative AI skills needed

The following are examples of new skills needed for the successful deployment of generative AI tools:

• data scientist:
• prompt engineering
• in-context learning
• bias detection
• pattern identification
• reinforcement learning from human feedback
• hyperparameter/large language model fine-tuning; transfer learning
• data engineer:
• data wrangling and data warehousing
• data pipeline construction
• multimodal processing
• vector database management

The learning process can take two to three months to get to a decent level of competence because of the complexities in learning what various LLMs can and can’t do and how best to use them. The coders need to gain experience building software, testing, and validating answers, for example. It took one financial-services company three months to train its best data scientists to a high level of competence. While courses and documentation are available—many LLM providers have boot camps for developers—we have found that the most effective way to build capabilities at scale is through apprenticeship, training people to then train others, and building communities of practitioners. Rotating experts through teams to train others, scheduling regular sessions for people to share learnings, and hosting biweekly documentation review sessions are practices that have proven successful in building communities of practitioners (see sidebar “A sample of new generative AI skills needed”).

It’s important to bear in mind that successful gen AI skills are about more than coding proficiency. Our experience in developing our own gen AI platform, Lilli , showed us that the best gen AI technical talent has design skills to uncover where to focus solutions, contextual understanding to ensure the most relevant and high-quality answers are generated, collaboration skills to work well with knowledge experts (to test and validate answers and develop an appropriate curation approach), strong forensic skills to figure out causes of breakdowns (is the issue the data, the interpretation of the user’s intent, the quality of metadata on embeddings, or something else?), and anticipation skills to conceive of and plan for possible outcomes and to put the right kind of tracking into their code. A pure coder who doesn’t intrinsically have these skills may not be as useful a team member.

While current upskilling is largely based on a “learn on the job” approach, we see a rapid market emerging for people who have learned these skills over the past year. That skill growth is moving quickly. GitHub reported that developers were working on gen AI projects “in big numbers,” and that 65,000 public gen AI projects were created on its platform in 2023—a jump of almost 250 percent over the previous year. If your company is just starting its gen AI journey, you could consider hiring two or three senior engineers who have built a gen AI shaper product for their companies. This could greatly accelerate your efforts.

Form a centralized team to establish standards that enable responsible scaling

To ensure that all parts of the business can scale gen AI capabilities, centralizing competencies is a natural first move. The critical focus for this central team will be to develop and put in place protocols and standards to support scale, ensuring that teams can access models while also minimizing risk and containing costs. The team’s work could include, for example, procuring models and prescribing ways to access them, developing standards for data readiness, setting up approved prompt libraries, and allocating resources.

While developing Lilli, our team had its mind on scale when it created an open plug-in architecture and setting standards for how APIs should function and be built.  They developed standardized tooling and infrastructure where teams could securely experiment and access a GPT LLM , a gateway with preapproved APIs that teams could access, and a self-serve developer portal. Our goal is that this approach, over time, can help shift “Lilli as a product” (that a handful of teams use to build specific solutions) to “Lilli as a platform” (that teams across the enterprise can access to build other products).

For teams developing gen AI solutions, squad composition will be similar to AI teams but with data engineers and data scientists with gen AI experience and more contributors from risk management, compliance, and legal functions. The general idea of staffing squads with resources that are federated from the different expertise areas will not change, but the skill composition of a gen-AI-intensive squad will.

Set up the technology architecture to scale

Building a gen AI model is often relatively straightforward, but making it fully operational at scale is a different matter entirely. We’ve seen engineers build a basic chatbot in a week, but releasing a stable, accurate, and compliant version that scales can take four months. That’s why, our experience shows, the actual model costs may be less than 10 to 15 percent of the total costs of the solution.

Building for scale doesn’t mean building a new technology architecture. But it does mean focusing on a few core decisions that simplify and speed up processes without breaking the bank. Three such decisions stand out:

• Focus on reusing your technology. Reusing code can increase the development speed of gen AI use cases by 30 to 50 percent. One good approach is simply creating a source for approved tools, code, and components. A financial-services company, for example, created a library of production-grade tools, which had been approved by both the security and legal teams, and made them available in a library for teams to use. More important is taking the time to identify and build those capabilities that are common across the most priority use cases. The same financial-services company, for example, identified three components that could be reused for more than 100 identified use cases. By building those first, they were able to generate a significant portion of the code base for all the identified use cases—essentially giving every application a big head start.
• Focus the architecture on enabling efficient connections between gen AI models and internal systems. For gen AI models to work effectively in the shaper archetype, they need access to a business’s data and applications. Advances in integration and orchestration frameworks have significantly reduced the effort required to make those connections. But laying out what those integrations are and how to enable them is critical to ensure these models work efficiently and to avoid the complexity that creates technical debt  (the “tax” a company pays in terms of time and resources needed to redress existing technology issues). Chief information officers and chief technology officers can define reference architectures and integration standards for their organizations. Key elements should include a model hub, which contains trained and approved models that can be provisioned on demand; standard APIs that act as bridges connecting gen AI models to applications or data; and context management and caching, which speed up processing by providing models with relevant information from enterprise data sources.
• Build up your testing and quality assurance capabilities. Our own experience building Lilli taught us to prioritize testing over development. Our team invested in not only developing testing protocols for each stage of development but also aligning the entire team so that, for example, it was clear who specifically needed to sign off on each stage of the process. This slowed down initial development but sped up the overall delivery pace and quality by cutting back on errors and the time needed to fix mistakes.

Ensure data quality and focus on unstructured data to fuel your models

The ability of a business to generate and scale value from gen AI models will depend on how well it takes advantage of its own data. As with technology, targeted upgrades to existing data architecture  are needed to maximize the future strategic benefits of gen AI:

• Be targeted in ramping up your data quality and data augmentation efforts. While data quality has always been an important issue, the scale and scope of data that gen AI models can use—especially unstructured data—has made this issue much more consequential. For this reason, it’s critical to get the data foundations right, from clarifying decision rights to defining clear data processes to establishing taxonomies so models can access the data they need. The companies that do this well tie their data quality and augmentation efforts to the specific AI/gen AI application and use case—you don’t need this data foundation to extend to every corner of the enterprise. This could mean, for example, developing a new data repository for all equipment specifications and reported issues to better support maintenance copilot applications.
• Understand what value is locked into your unstructured data. Most organizations have traditionally focused their data efforts on structured data (values that can be organized in tables, such as prices and features). But the real value from LLMs comes from their ability to work with unstructured data (for example, PowerPoint slides, videos, and text). Companies can map out which unstructured data sources are most valuable and establish metadata tagging standards so models can process the data and teams can find what they need (tagging is particularly important to help companies remove data from models as well, if necessary). Be creative in thinking about data opportunities. Some companies, for example, are interviewing senior employees as they retire and feeding that captured institutional knowledge into an LLM to help improve their copilot performance.
• Optimize to lower costs at scale. There is often as much as a tenfold difference between what companies pay for data and what they could be paying if they optimized their data infrastructure and underlying costs. This issue often stems from companies scaling their proofs of concept without optimizing their data approach. Two costs generally stand out. One is storage costs arising from companies uploading terabytes of data into the cloud and wanting that data available 24/7. In practice, companies rarely need more than 10 percent of their data to have that level of availability, and accessing the rest over a 24- or 48-hour period is a much cheaper option. The other costs relate to computation with models that require on-call access to thousands of processors to run. This is especially the case when companies are building their own models (the maker archetype) but also when they are using pretrained models and running them with their own data and use cases (the shaper archetype). Companies could take a close look at how they can optimize computation costs on cloud platforms—for instance, putting some models in a queue to run when processors aren’t being used (such as when Americans go to bed and consumption of computing services like Netflix decreases) is a much cheaper option.

Build trust and reusability to drive adoption and scale

Because many people have concerns about gen AI, the bar on explaining how these tools work is much higher than for most solutions. People who use the tools want to know how they work, not just what they do. So it’s important to invest extra time and money to build trust by ensuring model accuracy and making it easy to check answers.

One insurance company, for example, created a gen AI tool to help manage claims. As part of the tool, it listed all the guardrails that had been put in place, and for each answer provided a link to the sentence or page of the relevant policy documents. The company also used an LLM to generate many variations of the same question to ensure answer consistency. These steps, among others, were critical to helping end users build trust in the tool.

Part of the training for maintenance teams using a gen AI tool should be to help them understand the limitations of models and how best to get the right answers. That includes teaching workers strategies to get to the best answer as fast as possible by starting with broad questions then narrowing them down. This provides the model with more context, and it also helps remove any bias of the people who might think they know the answer already. Having model interfaces that look and feel the same as existing tools also helps users feel less pressured to learn something new each time a new application is introduced.

Getting to scale means that businesses will need to stop building one-off solutions that are hard to use for other similar use cases. One global energy and materials company, for example, has established ease of reuse as a key requirement for all gen AI models, and has found in early iterations that 50 to 60 percent of its components can be reused. This means setting standards for developing gen AI assets (for example, prompts and context) that can be easily reused for other cases.

While many of the risk issues relating to gen AI are evolutions of discussions that were already brewing—for instance, data privacy, security, bias risk, job displacement, and intellectual property protection—gen AI has greatly expanded that risk landscape. Just 21 percent of companies reporting AI adoption say they have established policies governing employees’ use of gen AI technologies.

Similarly, a set of tests for AI/gen AI solutions should be established to demonstrate that data privacy, debiasing, and intellectual property protection are respected. Some organizations, in fact, are proposing to release models accompanied with documentation that details their performance characteristics. Documenting your decisions and rationales can be particularly helpful in conversations with regulators.

In some ways, this article is premature—so much is changing that we’ll likely have a profoundly different understanding of gen AI and its capabilities in a year’s time. But the core truths of finding value and driving change will still apply. How well companies have learned those lessons may largely determine how successful they’ll be in capturing that value.

How teens and parents approach screen time, most teens at least sometimes feel happy and peaceful when they don’t have their phone, but 44% say this makes them anxious. half of parents say they have looked through their teen’s phone.

Pew Research Center conducted this study to better understand teens’ and parents’ experiences with screen time. 

The Center conducted an online survey of 1,453 U.S. teens and parents from Sept. 26 to Oct. 23, 2023, through Ipsos. Ipsos invited one parent from each of a representative set of households with parents of teens in the desired age range from its KnowledgePanel . The KnowledgePanel is a probability-based web panel recruited primarily through national, random sampling of residential addresses. Parents were asked to think about one teen in their household (if there were multiple teens ages 13 to 17 in the household, one was randomly chosen). At the conclusion of the parent’s section, the parent was asked to have this chosen teen come to the computer and complete the survey in private.

The survey is weighted to be representative of two different populations: 1) parents with teens ages 13 to 17 and 2) teens ages 13 to 17 who live with parents. For each of these populations, they survey is weighted to be representative by age, gender, race and ethnicity, household income and other categories.

This research was reviewed and approved by an external institutional review board (IRB), Advarra, an independent committee of experts specializing in helping to protect the rights of research participants.

Here are the questions among parents and among teens used for this report, along with responses, and its methodology ­­­.

Today’s teenagers are more digitally connected than ever. Most have access to smartphones and use social media , and nearly half say they are online almost constantly. But how are young people navigating this “always on” environment?  

To better understand their experiences, we surveyed both teens and parents on a range of screen time-related topics. Our questions explored the emotions teens tie to their devices, the impact of smartphones on youth, and the challenges parents face when raising children in the digital age.

Key findings from the survey:

• Phone-less: 72% of U.S. teens say they often or sometimes feel peaceful when they don’t have their smartphone; 44% say it makes them feel anxious.
• Good for hobbies, less so for socialization: 69% of teens say smartphones make it easier for youth to pursue hobbies and interests; fewer (30%) say it helps people their age learn good social skills.
• Parental snooping: Half of parents say they have looked through their teen’s phone.
• Smartphone standoffs: About four-in-ten parents and teens report regularly arguing with one another about time spent on their phone.
• Distracted parenting: Nearly half of teens (46%) say their parent is at least sometimes distracted by their phone when they’re trying to talk to them.

This Pew Research Center survey of 1,453 U.S. teens ages 13 to 17 and their parents was conducted Sept. 26-Oct. 23, 2023. 1

But the largest shares say the amount of time they spend on their phone (51%) or on social media (64%) is about right. Relatively few teens say they don’t spend enough time with these technologies.

Views on this differ by gender. Teen girls are more likely than boys to say they spend too much time on their smartphone (44% vs. 33%) or social media (32% vs. 22%).

Teens’ efforts to curb their screen time

A minority of teens have taken steps to reduce their screen time. Roughly four-in-ten teens (39%) say they have cut back on their time on social media. A similar share says the same about their phone (36%).

Still, most teens have not limited their smartphone (63%) or social media (60%) use.

How teens’ behaviors vary by gender

About four-in-ten or more girls say they have cut back on their smartphone or social media use. For boys, those figures drop to roughly one-third.

How teens’ behaviors vary based on their screen time

Teens who report spending too much time on social media and smartphones are especially likely to report cutting back on each. For instance, roughly six-in-ten teens who say they are on social media too much say they have cut back (57%). This is far higher than the 32% among those who say they are on social media too little or the right amount.

How teens feel when they don’t have their phone

Teens encounter a range of emotions when they don’t have their phones, but we asked them about five specific ones. Roughly three-quarters of teens say it often or sometimes makes them feel happy (74%) or peaceful (72%) when they don’t have their smartphone.

Smaller but notable shares of teens equate not having their phone with more negative emotions. Teens say not having their phone at least sometimes makes them feel anxious (44%), upset (40%) and lonely (39%).

It is worth noting that only a minority of teens – ranging from 7% to 32% – say they often feel these emotions when they’re phone-less.

Teens’ feelings on this differ by some demographic factors:

• Age and gender: Older girls ages 15 to 17 (55%) are more likely than younger girls (41%) and teen boys who are younger (41%) and older (40%) to say they feel anxious at least sometimes when they don’t have their smartphone.
• Gender: 45% of teen girls say not having their phone makes them feel lonely regularly, compared with 34% of teen boys.

Do teens think smartphones are negatively impacting young people?

As smartphones have become a universal part of teen life, many have asked what impact, if any, phones are having on today’s youth.

Teens shared their perspectives on smartphones’ impact on people their age and whether these devices have made certain aspects of growing up more or less challenging.

Most teens think the benefits of smartphones outweigh the harms for people their age. Seven-in-ten teens say smartphones provide more benefits than harms for people their age, while a smaller share (30%) take the opposing view, saying there are more harms than benefits.

Teens’ views, by gender and age

Younger girls ages 13 and 14 (39%) are more likely than older teen girls (29%) and teen boys who are younger (29%) and older (25%) to say that the harms of people their age using smartphones outweigh the benefits.

The survey also shows that teens see these devices’ impacts on specific aspects of life differently.

More teens believe smartphones make it easier, rather than harder, to be creative, pursue hobbies and do well in school. Majorities of teens say smartphones make it a little or a lot easier for people their age to pursue hobbies and interests (69%) and be creative (65%). Close to half (45%) say these devices have made it easier for youth to do well in school.

Views are more mixed when it comes to developing healthy friendships. Roughly four-in-ten teens say smartphones make it easier for teens to develop healthy friendships, while 31% each say they make it harder or neither easier nor harder.

But they think smartphones have a more negative than positive impact on teens’ social skills. A larger percentage of teens say smartphones make learning good social skills harder (42%) rather than easier (30%). About three-in-ten say it neither helps nor hurts.

How parents navigate raising teens in the smartphone age

With the rise of smartphones, today’s parents must tackle many questions that previous generations did not. How closely should you monitor their phone use? How much screen time is too much? And how often do phones lead to disagreements?

We developed a set of parallel questions to understand the perspectives of both parents and teens. Here’s what we found:

It’s common for parents to look through their teen’s phone – and many of their teens know it. Half of parents of teens say they look through their teen’s phone. When we asked teens if they thought their parents ever look through their phones, 43% believed this had happened.

Whether parents report looking through their child’s smartphone depends on their kid’s age. While 64% of parents of 13- to 14-year-olds say they look through their teen’s smartphone, this share drops to 41% among parents of 15- to 17-year-olds.

Teens’ accounts of this also vary depending on their age: 56% of 13- to 14-year-olds say their parent checks their smartphone, compared with 35% of teens ages 15 to 17.

How often do parents and teens argue about phone time?

Parents and teens are equally likely to say they argue about phone use. Roughly four-in-ten parents and teens (38% each) say they at least sometimes argue with each other about how much time their teen spends on the phone. This includes 10% in each group who say this happens often .

Still, others say they never have these types of disagreements. One-quarter of parents say they never argue with their teen about this, while 31% of teens say the same.

Teens’ and parents’ views, by race and ethnicity

Hispanic Americans stand out for reporting having these disagreements often. While 16% of Hispanic teens say they often argue with their parent about how much time they’re spending on their phone, that share drops to 9% for White teens and 6% for Black teens. 3

A similar pattern is present among parents. Hispanic parents (19%) are more likely than White (6%) or Black (7%) parents to say they often argue with their teen about this.

Teens’ views, by frequency of internet use

The amount of time teens report being online is also a factor. About half (47%) of teens who report being online almost constantly say they at least sometimes argue with their parent about the amount of time they spend on their phone, compared with those who are online less often (30%). 

How much do parents prioritize tracking their teen’s phone use?

Most parents prioritize managing the amount of time their teen spends on the phone. Roughly three-quarters of parents (76%) say managing how much time their teen spends on the phone is an important or a top priority.  Still, 19% of parents don’t consider this a priority.

Parents’ views, by race and ethnicity

Majorities of parents across racial and ethnic groups think of this as a priority. But some groups stand out for how much they prioritize this. For example, Hispanic (25%) or Black (24%) parents are more likely to say managing how much time their teen is on the phone is a top priority. That share drops to 10% among White parents.

Parents’ views, by household income

We also see differences between the lowest and highest income households: 22% of parents whose annual household income is less than $30,000 consider managing the amount of time their teen is on the phone a top priority, compared with 14% of those whose household income is $75,000 or more a year. Those whose household income is $30,000 to $74,999 a year do not meaningfully differ from either group.

Do parents set time limits on their teen’s phone use?

There’s a nearly even split between parents who restrict their teen’s time on their phone and those who don’t. About half of parents (47%) say they limit the amount of time their teen can be on their phone, while a similar share (48%) don’t do this.

Parents’ views, by teen’s age

Parents of younger teens are far more likely to regulate their child’s screen time. While 62% of parents of 13- to 14-year-olds say they limit how much time their teen can be on their phone, that share drops to 37% among those with a 15- to 17-year-old.

How difficult is it for parents to keep up with their teen’s phone use?

Managing screen time can feel like an uphill battle for some parents. About four-in-ten say it’s hard to manage how much time their teen spends on their phone. A smaller share (26%) says this is easy to do. 

Another 26% of parents fall in the middle – saying it’s neither easy nor hard.

Higher-income parents are more likely to find it difficult to manage their teen’s phone time. Roughly half (47%) of parents living in households earning $75,000 or more a year say managing the amount of time their teen is on their phone is hard. These shares are smaller among parents whose annual household income falls below $30,000 (38%) or is between $30,000 and $74,999 (32%).

Parents’ own struggles with device distractions, screen time

Teens aren’t the only ones who can be glued to their phones. Parents, too, can find themselves in an endless cycle of checking emails , text messages and social media.

With that in mind, we asked parents to think about their own screen time – both the time they spend on their phone, and if it ever gets in the way of connecting with their teen.

Do parents think they spend too much time on their phone?

Like teens, parents are far more likely to say they spend too much rather than not enough time on their phone. About half of parents (47%) say they spend too much time on their smartphone. Just 5% think they spend too little time on it. And 45% believe they spend the right amount of time on their phone.

Parents’ views differ by:

• Household Income: 50% of parents with annual household incomes of $75,000 or more say they spend too much time on their phone. This share drops to 41% among those living in households earning $30,000 to $74,999 a year and 38% among those earning under $30,000.
• Race and ethnicity: 57% of White parents believe they spend too much time on their phone, compared with 38% of Black parents and 34% of Hispanic parents.

How often are parents distracted by their phone when talking with their teen?

When it comes to distracted parenting, parents paint a rosier picture than teens. Nearly half of teens (46%) say their parent is at least sometimes distracted by their phone when they’re trying to talk to them, including 8% who say this happens often.

But when parents were asked to assess their own behavior, fewer – 31% – say this happens regularly.

Department of Defense Announces Fiscal Year 2024 University Research Funding Awards

The Department of Defense today announced $221 million in awards for basic defense-related research projects as part of the Multidisciplinary University Research Initiative (MURI) program. At an average award amount of $7.5 million over five years, these competitive grants will support 30 teams located at 73 U.S. academic institutions, subject to satisfactory research progress and the availability of funds.

"The science and engineering challenges we face today are highly complex and cross disciplinary," said Dr. Bindu Nair, director of the Basic Research Office in the Office of the Under Secretary of Defense for Research and Engineering. "The MURI program acknowledges these complexities by supporting teams whose members have diverse sets of expertise as well as creative scientific approaches to tackling problems. 

"This cross-fertilization of ideas can accelerate research progress to enable more rapid scientific breakthroughs and hasten the transition of basic research funding to practical applications. The program is a cornerstone of DoD's basic research portfolio and a strong contributor to its legacy of scientific impact." 

Since its inception in 1985, the Department's MURI program has allowed teams of investigators from multiple disciplines to generate collective insights, facilitating the growth of cutting-edge technologies to address the Department's unique challenges. 

The highly competitive program, which complements the Department's single-investigator basic research grants, has made immense contributions to current and future military capabilities and produced numerous commercial sector applications. 

Notable MURI achievements include breakthroughs in cold-atom quantum methods with potential applications in quantum sensing and communication, as well as advances in pulsed magnetic field propagation and Doppler radar detection leading to new detection physics for landmines.

The Fiscal Year 2024 competition identified six topics that received an additional $1.5 million each over the five-year award term specifically to support the participation of historically Black colleges and universities and minority-serving institutions (HBCU/MIs). Seven proposals selected across the six topics will receive support for HBCU/MI participation on the MURI projects.

The Army Research Office, Air Force Office of Scientific Research, and Office of Naval Research solicited Fiscal Year 2024 proposals in 25 topic areas of strategic importance to the Department. After a merit-based review of 276 white papers, a panel of experts narrowed the pool to a subset of 102 full proposals, from which the 30 final awards were selected.
