A teenager’s brain does not magically mature into its reasoned, adult form the night before his or her 18th birthday. Instead, aspects of brain development stretch into a person’s 20s — a protracted fine-tuning with serious implications for young people caught in the U.S. justice system, argues cognitive neuroscientist B.J. Casey of Yale University.
In the May 22 Neuron, Casey describes...
The World Health Organization’s goal was lofty but achievable: eliminate measles from five of the world’s six regions by 2020. But recent outbreaks — even in places where elimination had been achieved — are making that goal a distant dream.
In the first four months of 2019, 179 countries reported 168,193 cases of measles. That’s almost 117,000 more cases reported during the same period...
Humans are problem solvers. All day, every day, we ask ourselves questions. Should I wear socks with these shoes? Bring a phone charger? Eat the whole sandwich? Finish that assignment or watch YouTube? And that’s just an average day. When we apply the tools of science to answering big questions, we can do amazing things.05/11/2019 - 07:15 Science & Society
In this double issue of Science News, we profile scientists...
Stories about individual species on the brink of extinction may be all too familiar. But a new tally now reveals the breadth of the conservation crisis: One million of the world’s species are now poised to vanish, some as soon as within the next few decades.
That number, which amounts to 1 in every 8 animal or plant species on Earth, comes from a sweeping new analysis of about 15,000...
Men are “scientific,” women are “lovely” and underrepresented minorites are “pleasant” and “nice.” If those sound like stereotypes, they are. But they’re also words commonly used to evaluate medical students, a study finds.
Analysis of nearly 88,000 evaluations of third-year medical students written from 2006 to 2015 revealed evidence of implicit bias. White women and underrepresented...
Hurricane Maria sent Puerto Ricans fleeing from the island to the U.S. mainland, but population surveys to assess the size of that migration would have taken at least a year to complete. A new study suggests, however, that a Facebook tool for advertisers could provide crude, real-time estimates for how many people are moving because of a natural disaster. That could help governments design...
Professor Schrödenberg is missing, and evil agents want to use her quantum computing research for nefarious purposes. Stopping them is up to you, but completing your mission will require solving some mind-bending puzzles —based on science.
If you are up for the challenge, you can test your wits at LabEscape, a science-themed escape room at the Lincoln Square Mall in Urbana, Ill. Escape...
This is part of the Transparency Project, which explains how we do science journalism. This article refers to a story published in April 2018, “New genetic sleuthing tools helped track down the Golden State Killer suspect.”
I was in the midst of writing a series on consumer DNA testing when news broke that police had arrested a suspect in the Golden State Killer case. Investigators had...
This is part of the Transparency Project, which explains how we do science journalism. This article refers to a story published in April 2019, “New fossils may capture the minutes after the dinosaur-killing asteroid impact.”How did you find this story?
This was an unusual story for us because it was based not only on a research paper published in a scientific journal, which is the type...
Here at Science News we work hard to make sure that our coverage of the latest advances in science, medicine and technology is clear, accurate and comprehensive. But we realize that what’s clear to us about how we do science journalism may not be clear to our readers. And we want to be open and accountable about that process.
So we’re launching the Transparency Project. In the coming...
