Before 2010, scientists knew very little about how the sensation of touch begins its journey into a person’s consciousness. They knew that nerve endings help carry the message from different parts of our bodies to our brains. But they didn’t know what kind of receptor on the nerve ending causes the message to fire —
Kids are back in school. The federal government seems to be on the verge of approving vaccines for younger children. And as more adults are fully vaccinated, much of the US is slowly returning to normal. But there remains a lingering question, particularly for parents of young children: What is the risk of Covid-19 to
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
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
Four executives from Big Oil — “the richest, most powerful industry in human history,” according to environmentalist Bill McKibben — testified before Congress on Thursday at a hearing meant to reveal how the oil business has undermined government action on climate change. The House Committee on Oversight and Reform questioned the CEOs of ExxonMobil, BP,
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
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
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
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
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
