Fourteen thousand years ago, a star called Vela died. Its core collapsed first and then, in a violent burst, propelled the shattered star’s body out into space. Vela’s death bled into the interstellar medium, blasting cosmic radiation out in every direction. For 800 years, the guts of this star traveled from its location in the […]

Winter and the holidays can be hard even in typical years: short days, cold winds, and family stress, to name a few. But the ongoing US Covid-19 surge, with more than 200,000 new virus cases reported every day since December 7 (about double what they were a month before), is putting the hallmark activities that […]

“I am seeing tons of hair loss,” Mona Gohara says. Patients come to Gohara, a dermatologist and professor at the Yale School of Medicine, for all kinds of reasons from skin cancer screenings to cosmetic procedures. But this year more than ever, they’re worried about their hair. It’s not a coincidence. Stress — like, say, […]

There are around 1,000 mountain gorillas left in the wild, and about 460 of them live in Bwindi Impenetrable National Park in Uganda. In the park’s very dense, high-altitude forest (hence the name “impenetrable”), veterinarian Gladys Kalema-Zikusoka is working to keep them alive through the Covid-19 pandemic. No gorilla has come down with Covid-19, but […]

Governors, mayors, and public health officials are sounding the alarm about rising levels of Covid-19 across every part of the country. The disease is surging, the death toll is soaring, and it’s clear that some states need more restrictive measures to control the spread. What continues to frustrate so many leaders is that nine months […]

As of mid-December, hospitals on average had just 22 percent of their intensive care unit (ICU) beds available across the country, and many were completely full. As the Covid-19 surge continues to intensify, lack of ICU beds can have dire consequences, including not being able to properly care for the sickest patients, potentially rationing lifesaving […]

The room didn’t spin like they say it does. My life didn’t flash before my eyes. I had no difficulty understanding the verdict: It was incurable. They could offer no prognosis. They had some general ideas about how they might treat me; it was considered “manageable” in its normal form, but in my case, there […]

Two highly effective Covid-19 vaccines are now being administered across the United States, and more are in the pipeline. Almost 2 million people have already received the first of two doses of these vaccines, and officials are aiming to immunize one-third of the US population by the end of March 2021. It’s a stunning accomplishment […]

It’s the year 2020, and scientists are still discovering new species of life on Earth. No one knows exactly how many types of life are yet undescribed in the scientific literature; estimates range from around 86 percent to as high as 99.99 percent. And even though we’re living through an age of great biodiversity loss, […]

It’s year-end-list season. Usually, the Vox science team has some fun and compiles a year-end list of bad ideas in health and science that ought to die with the end of the year. In the past, we’ve targeted homeopathic medicine, declared it was time to end the relevance of the fatally flawed Stanford Prison Experiment, […]
