How biological detective work can reveal who engineered a virus
SARS-CoV-2, the virus that causes Covid-19, has made our future vulnerability to biological pathogens — and what we can learn to help prevent the next pandemic — a salient concern. We don’t have much evidence one way or the other whether Covid’s emergence into the world was the result of a lab accident or a…
Playdates are ruining all the fun
It’s become a time-honored tradition in certain segments of American society: two families cross-reference their respective calendars to find a spot free of school or soccer or other obligations. On the appointed day, one child travels to the other’s house, typically accompanied by a parent. The children build a Lego village or glue googly eyes…
Is it okay to harvest pig kidneys to save human lives?
“David is a great transplant surgeon. Five of his patients need new parts — one needs a heart, the others need, respectively, liver, stomach, spleen, and spinal cord — but all are of the same, relatively rare, blood-type.

Are “net-zero” climate targets just hot air?
Corporations and countries around the world are promising to eliminate their contributions to climate change. But many of their targets for cutting greenhouse gas emissions are prefaced by a slippery phrase: “net-zero.” More than 130 countries have set or are considering net-zero emissions goals, and many are stepping up as they prepare for next week’s…
The fate of the planet will be negotiated in Glasgow, Scotland
Almost every country in the world signed the 2015 Paris climate agreement, a monumental accord that aimed to limit global warming. But it was forged on a contradiction: Every signatory agreed that everyone must do something to address the urgent threat of climate change, but no one at the time pledged to do enough. In…
Biden’s $27 billion bet on forests
As the White House revealed Thursday, President Joe Biden has stripped a lot from his Build Back Better framework to placate moderate Democrats. Free community college is out, as is Medicare coverage of dental and vision services, among several other priorities. But there is one surprising area that’s so far survived the congressional gauntlet as…
Covid-19 vaccines for young kids are a big step toward a new normal
More than 28 million children across the US are now eligible to receive Covid-19 vaccinations, a step that could relieve anxiety for families, bring more kids back to schools, and slow the spread of the disease. On Tuesday, the Centers for Disease Control and Prevention endorsed the Pfizer/BioNTech vaccine for kids between the ages of…
The curious case of the ancient whale bones
Every year, thousands of whales strand — meaning that they wind up trapped on beaches or in shallow waters — and it’s really hard to figure out why. It’s not for lack of trying. Teams of forensic researchers investigate stranded whales, studying organs, analyzing body parts with CT scanners, digging through stomach contents, and checking…
