If you have a cough or a fever nowadays, you know exactly what to do: go to the doctor, get a COVID test, and quarantine so you can stop the spread. But we also know that plenty of people contract COVID-19 and transmit it before they know they have it — and some people never even realize that they are contagious at all. So, when it comes to asymptomatic carriers, how do you shut down the line of transmission? According to Dr. Michael Mina, an epidemiologist and immunologist at Harvard Medical Sc...

When we last spoke with Dariush Mozaffarian, dean of the Friedman School of Nutrition Science and Policy at Tufts University, about COVID-19 and obesity back in June, the pandemic was still relatively new. We didn’t know how long it would take to get a vaccine, how many would be affected or who would struggle the most. Mozaffarian was just beginning to sift through some of the early hospitalization data, and he noticed one risk factor that seemed to be particularly risky: obesity. Now, with far ...

The pandemic has been a catastrophe for tourism and travel, upending an almost $9 trillion industry that once accounted for approximately 330 million jobs around the world. And there continues to be great uncertainty about what the future holds. When will everyone feel safe to fly again? When we do, where will we want to go, and will we be able to afford it? The road to recovery for American leisure and business travel will be long and complicated, according to Henry Harteveldt, an industry anal...

You might not think that a simulation meant for kids could change how something plays out in real life, but in the 1990s, the arcade game NBA Jam did exactly that. One feature of the game allowed players to be “on fire.” The more a player scored, the higher chance he or she had of scoring again. Fast forward to today and you can’t escape the concept of a hot streak, or a “hot hand”' as it’s called in basketball. Athletes swear by it, even refusing to touch another player’s “hot” hand. But is a h...

From our smartphones to our bicycles, the user experience provided by manufactured products has an enormous impact on our lives. Down to the smallest details, designers often puzzle over how to best align a product with the demands of the customer. But that wasn’t always the approach, and Cliff Kuang, author of User Friendly: How the Hidden Rules of Design Are Changing the Way We Live, Work, and Play, explains how this revolution of design has taken hold and dramatically changed our patterns of ...

In offices around the country, mail has piled up. Plants have died. Coffee cups sit unwashed, with a ring of old espresso cemented to the bottom. In some buildings, the lights have been left on since March — and who knows when someone will be back to turn them off. According to Stanford economist Nicholas Bloom, we’re in the middle of “a structural, seismic shift” in the workplace. The majority of employees booted out of the office earlier this year don’t want to come back, says Liz Fosslein, he...

In the past few months, a pandemic of mental health has shadowed COVID-19. Across the country, cases of depression, anxiety, alcoholism and domestic violence have been on the rise — intensifying an existing shortage of mental health care providers. With shutdowns and social distancing guidelines, access to therapy has also changed dramatically, with a forced transition to online sessions. This switch to telepsychiatry is a big move but, according to Dr. Peter Yellowlees, a psychiatry professor a...

About 1500 years ago, the world was a very different place; Pope Gregory was spreading Catholicism far and wide, a plague was running rampant, and some dominoes were about to start falling. The end of that cascade would end up in a world where a certain group of people started to think quite differently from those who had come before them. Their brains began to change, the societies they built thrived and they grew so influential and culturally dominant that their way of thinking permeated our e...

In the spring, more than 50 million K-12 students were hurriedly sent home as the nation’s public schools shut down because of the coronavirus pandemic. Some of those students have returned to their classrooms now, for full or partial in-person instruction, while others have continued with distance learning or quit public school systems altogether. Paul Reville, a professor at the Harvard Graduate School of Education, and Pedro Noguera, dean of the University of Southern California Rossier Schoo...

The pandemic has made life as an artist hard — real hard. Museums and studios have closed, live shows have been canceled and concerts have been pushed online. But according to William Deresiewicz, this is just the most recent act in a long, profound shift in the arts. Deresiewicz, a former English professor at Yale University and author of “The Death of the Artist: How Creators Are Struggling to Survive in the Age of Billionaires and Big Tech,” says the digital age has devastated and demonetized...

Years of good marketing may have convinced us that life isn’t complete without a junk drawer, overflowing closet or unusable garage. Now, according to historian Wendy Woloson, Americans are suffering from the outright “crapification” of their lives. So where do we go from here? And how do we clear out that closet? Woloson, an associate professor of history at Rutgers University Camden and author of “Crap: A History of Cheap Stuff in America,” says our relationship with junk goes way back. We’re ...

Some scientists and environmentalists believe that the novel coronavirus is nature’s warning to us about the unsustainable ways we have been living. The rate of human development and the encroachment into the natural habitats of wild animals have left us dangerously susceptible to the spread of deadly infectious diseases, they say. CNN host and Washington Post columnist, Fareed Zakaria, also fears the current crisis could be a “dress rehearsal” for an even more deadly threat, because disruptive ...

Over the past month, the Senate has rushed to fill Justice Ruth Bader Ginsburg’s seat on the Supreme Court. Both Republicans and Democrats have claimed that the other is inappropriately reshaping, or considering reshaping, the Court. But how did the Supreme Court get so caught up in politics? And is there a way out?

While some of us may be tempted to put our hopes in the development of a miracle vaccine or magical cure for the new coronavirus, holding out for a perfect solution could be unwise. The rapid and extensive use of a number of imperfect prevention and treatment methods, is the key to turning the tide, according to Dr. Joshua Schiffer. Schiffer, an associate professor in the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center, discusses the benefits of some effecti...

Last April, states began to sporadically reopen after weeks of being shut down. South Carolina was among the first to begin the process and some others would soon follow, while some states wouldn’t start until June. The uncoordinated reopening caused chaos, according to Sinan Aral, director of MIT’s Initiative on the Digital Economy. As people watched their social feeds fill with images of people heading back outside, they stepped out too — even if their state wasn’t at the same phase. Aral, aut...

In the past six months, tens of millions of Americans have lost their jobs and the federal government has provided more than $400 billion in unemployment benefits. With states pressed to pay for the epic costs of coronavirus, what if there was a more efficient way to get support to those out of work? What if we could save money while guaranteeing jobs? According to Pavlina Tcherneva, associate professor of economics at Bard College and author of “The Case for a Job Guarantee,” there’s a way to d...

The pandemic has caused a steep economic decline in the U.S. But many experts worried we were already in trouble before the coronavirus because of the rise of economic powerhouses with huge populations, such as China and India. That has also been a concern of Matthew Yglesias who has a radical solution for our economic woes: take the current U.S. population and triple it in the decades to come. Yglesias, the co-founder of Vox and the author of “One Billion Americans: The Case for Thinking Bigger...

On Oct. 4, 1957, Russia shocked the U.S. by launching the world’s first artificial satellite into orbit. Sputnik’s launch ignited a 20-year Space Race that would put men on the moon and push science and technology forward leaps and bounds. Now, as COVID-19 shocks the world again, Regina Dugan says we could be entering a new era marked by big breakthroughs in medical science. Dugan, former director of the Defense Advanced Research Projects Agency (DARPA) and CEO of Wellcome Leap, says this Health...

As COVID-19 began to sweep through the U.S. in early March, New York Governor Andrew Cuomo, among others, declared it the “great equalizer” — an experience uniquely universal. But six months and 200,000 deaths later, it’s clear that the pandemic has made an unequal society, well, more unequal. According to political scientist and international risk consultant Ian Bremmer, economic disparity and political polarization are on the rise globally too. When we finally reach a long-sought post-pandemic...

During this pandemic, we may be acutely aware that our love lives and family lives are entwined with the technology that’s all around us. But in fact, machines have been re-inventing our relationships since the days of the ancient plow, which likely led to the birth of marriage itself. That’s according to Debora Spar, a professor at Harvard Business School and former president of Barnard College.

Election season is upon us and everywhere you look someone is trying to coax you to vote for their candidate or issue. As we all know, old habits die hard and getting a person to shift their deeply-held opinions, political or otherwise, isn’t easy.

Colleges and universities nationwide were already facing a challenging landscape before the pandemic, but the fall of 2020 is testing them in ways they never could have anticipated. Some are doing remote-only learning, some are hybrid, and some are fully in-person. And this academic year could be the tipping point that potentially upends the entire higher education sector. According to Jeff Selingo, the former editor of the Chronicle of Higher Education and author of “Who Gets In and Why: A Year...

Young adults have often been criticized during the coronavirus pandemic. Now, as some colleges and universities open up their campuses for in-person and online classes, complaints and warnings to students are ratcheting up. But Julia Marcus, an infectious disease epidemiologist and assistant professor at Harvard Medical School, doesn’t believe that a punitive approach is the best way to reopen schools. She discusses a holistic public health strategy that she says will support students, instead o...

It’s no secret that men and women are different — it’s the punchline of a hundred jokes. But does our sex really show in our brains, or is there something else at play? Gina Rippon, a neuroscientist at Aston University in the U.K. and author of “Gender and Our Brains,” argues that sex doesn’t play nearly as big a role in influencing our brains as we might think. Rather, she says, social cues likely start to influence children at very, very young ages - and it is those cues that account for many ...

When you hear the name “Stanford,” chances are a certain university in Palo Alto, CA will come to mind. But you may be less familiar with the story of Leland Stanford, the university’s founder. As a railway entrepreneur and key player in West Coast politics, Stanford lived a controversial life that changed the history of California, strengthened a divided nation, and planted the seeds for the rise of Silicon Valley.

Humans have always enjoyed a good laugh, but the concept of stand-up comedy is relatively new. Wayne Federman, a comedian who teaches at the University of Southern California, and hosts the podcast The History of Stand Up, talks about the origin of the modern comedian. From the earliest vaudeville circuits, to the rise of the comedy record, to the role of late-night television in break-out comedy moments, we pay tribute to the power of the comedian.

Americans buy, on average, almost 70 items of clothing a year. And many of those garments are worn just seven to ten times before being thrown away. This breakneck consumption of clothes is only possible because of fast fashion, a system in which clothing is made quickly, sold cheaply, and seen as pretty disposable. Dana Thomas, author of “Fashionopolis: The Price of Fast Fashion and the Future of Clothes,” walks us through the origins and effects of fast fashion.

As the 2020 presidential election approaches, fears about the security of our democracy are heightening, particularly as COVID-19 forces us to adapt our voting practices. Many states are expanding access to mail-in voting, prompting cries of fraud from the Trump administration. But maybe it’s traditional voting machines that we should really be worried about, instead of mailed-in paper ballots, says J. Alex Halderman. Halderman is a professor of Computer Science and Engineering at the University...

Since the beginning of the pandemic, the world has seemed a little quieter. But that doesn’t mean you’re not being inundated with noise. Whether the sound is something you chose, like music or our podcast, or something outside of your control, like traffic outside or planes overhead, it’s likely that you rarely experience true silence. According to David Owen, a staff writer at The New Yorker and the author of “Volume Control: Hearing in a Deafening World,” all that noise is permanently changing...
