Why it’s so hard to be a nurse in America, according to two nurses
Last month, at the start of a fourth Covid-19 wave in the US, a nurse in a Seattle-area intensive-care unit announced her resignation on Twitter. “No amount of money could convince me to stay on as a bedside ICU nurse right now,” she wrote. “I can’t continue to live with the toll on my body…
Solar farms are often bad for biodiversity — but they don’t have to be
Every several years — sometimes just once a decade — when the rains come in just the right amounts and at just the right times, rare flowers speckle the Mojave Desert in California. Some, like the Barstow woolly sunflower, emerge from plants no larger than a thumbnail. They spring forth from seeds that have persisted…
Astronomers were skeptical about dark matter — until Vera Rubin came along
Vera Rubin didn’t “discover” dark matter, but she put it on the map. Dark matter is a wild concept. It’s the idea that some mind-boggling percentage of all the matter in the universe may be invisible, and wholly unlike the matter that makes up Earth. Rubin is celebrated because she forced much of the astronomy…
How a cheap antidepressant emerged as a promising Covid-19 treatment
Since Covid-19 patients started showing up at clinics and hospitals a year and a half ago, doctors and researchers have been hard at work trying to figure out how to treat them.

What full FDA approval for Covid-19 vaccines really means
Nearly nine months after the first Americans received their shots, the Covid-19 vaccine from Pfizer/BioNTech received full approval from the Food and Drug Administration for people 16 and older on Monday. This could help increase the number of people willing to get vaccines and make it easier to compel those who are less willing —…
The lab leak hypothesis — true or not — should teach us a lesson
The origins of the novel coronavirus that caused the Covid-19 pandemic remain a mystery. US intelligence agencies have now completed a 90-day probe into the origins of SARS-CoV-2, but their classified findings, according to the New York Times, were inconclusive as to whether the virus escaped from a laboratory in Wuhan, China, or made a…
What do hurricane categories mean?
Hurricane Ida has begun pummeling the Gulf Coast, making landfall as a Category 4 storm on Sunday near Port Fourchon, Louisiana. The storm has already tied for the strongest recorded landfall in Louisiana, with winds at 150 miles per hour. Hurricane Laura in 2020 also had 150-mile-per-hour winds, as did an 1856 hurricane, according to…
Hurricane Ida could ravage the Covid-strained Gulf Coast
Hurricane season brings a recurring set of difficulties to coastal communities, and particularly to the South. Like other natural disasters, hurricanes can lay bare inadequate infrastructure, political ineptitude, and stark racial and economic inequalities. For residents of the Gulf Coast region, Hurricane Ida comes 16 years — to the day — after Hurricane Katrina and…
What’s causing California’s unprecedented wildfires
Another explosive wildfire season is underway in California, with more than a million acres already burned in 2021. While still short of the unprecedented 2020 fire season, the blazes this year are well above average and are still gaining ground. The Caldor Fire burning near Lake Tahoe has forced thousands of people to evacuate as…
What an enormous global study can tell us about feeling better during the pandemic
During the pandemic, I’ve spent a lot of time alone. I live by myself. I work from home. At times, I experienced fits of fidgetiness and restlessness, contributing to feelings of burnout. Here’s what helped: reappraising the situation. What I was feeling was isolation, and the loneliness that comes with it. Instead of letting it…
