Why some biologists and ecologists think social media is a risk to humanity

Social media has drastically restructured the way we communicate in an incredibly short period of time. We can discover, “Like,” click on, and share information faster than ever before, guided by algorithms most of us don’t quite understand. And while some social scientists, journalists, and activists have been raising concerns about how this is affecting our democracy, mental health, and relationships, we haven’t seen biologists and ecologists weighing in as much. That’s changed with a…

Animals can navigate by starlight. Here’s how we know.

“No, no, no, no, Brian. No, no, no, no.” I had asked Stephen Emlen, a Cornell emeritus professor of neurobiology and behavior, what seemed to me an obvious question: When he brought birds into planetariums in the 1960s and 70s, did they ever, um, make a mess in there? “No poops in the planetarium,” Emlen assures me. I had called Emlen to talk not about poops, but a series of experiments that have captured my…

What if the truth isn’t out there?

The US military’s official report on UFOs is here, and its conclusion is scintillating: There’s some stuff in the sky, the government isn’t sure what it is, there’s no evidence that it’s aliens, but also no one’s ruling out aliens. So in conclusion, the UFOs are part of life’s rich pageant and anything is possible. The nine-page report released by the Director of National Intelligence’s (DNI) office last week, formally titled “Preliminary Assessment: Unidentified Aerial…

How heat waves form, and how climate change makes them worse

The Pacific Northwest is sweltering under a record-breaking heat wave. Portland reached 116 degrees Fahrenheit this week. Seattle reached 108 degrees. Vancouver reached 89 degrees.

This follows weeks of extremely high temperatures across the Northern Hemisphere and an early-season heat wave in North…

The US health system was already falling short. Then Covid-19 happened.

Take a long enough lens — say, 25 years — and it seems as though health care in America is inarguably getting better. People are living longer than they did a quarter century ago. The burden of disease, a metric that includes premature deaths and disability, has dropped. The number of avoidable hospitalizations and hospital errors is lower. But below those rosy numbers is the truth: American health care has been falling behind other countries…

How political polarization broke America’s vaccine campaign

The Covid-19 epidemic in the United States risks becoming a tale of “two Americas,” as Anthony Fauci warned in June: a nation where regions with higher vaccination rates are able to beat back the coronavirus, while those with lower vaccination rates continue to see cases and deaths. At face value, it’s a division between those who are vaccinated and those who are unvaccinated. But, increasingly, it’s also a division between Democrats and Republicans — as…
