A prion sickness similar to mad cow is spreading rapidly through North America’s deer and elk populations. A veterinary microbiologist discusses the options for keeping it in check.
Delegates from 175 nations are working on an international agreement that would tackle the vast amounts of plastic waste in the environment. A marine scientist specializing in plastic pollution discusses the problem and her hopes for the proceedings.
The push to legalize magic mushrooms, MDMA, LSD and other hallucinogens is likely to heighten tensions between state and federal law, drug law expert Robert Mikos says
Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity
New research suggests that to maintain a healthy brain, we should tend our gut microbiome. The best way to do that right now is not through pills and supplements, but better food.
Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, where the variety of magma types make for a geological paradise
As glacial cliffs break off and destabilize frozen landscapes, glaciologist Richard Alley focuses on the fractures. The work could improve predictions about future sea-level rise.
A scientist whose work was key to identifying, studying and finding treatments for this life-threatening virus discusses the scientific journey and challenges that persist
Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.
Measurements of the acceleration of the universe don’t agree, stumping physicists working to understand the cosmic past and future. A new proposal seeks to better align these estimates — and is likely testable.
These stealthy survival tactics could teach us how to curb the widespread use of chemical pesticides in agriculture. But first, researchers must learn how seemingly helpless flora deploy this masterful strategy.
The wet landmasses, though inherently impermanent, have been essential to both people and wildlife for thousands of years. But recent shifts have brought on some rapid losses that worry scientists.
The pandemic put the technology, long in development, to the test. Here’s a look at the status of its application to cancer and when it might reach patients.
Our bodies crave more food if we haven’t had enough protein, and this can lead to a vicious cycle — especially if we’re reaching for ultraprocessed instead of high-fiber whole foods
Adolescents’ brains are highly capable, if inconsistent, during this critical age of exploration and development. They are also acutely tuned into rewards.
In Latin America, tens of millions of people live in territories that are governed by outlaws — from powerful drug cartels to crime syndicates. What can be done to restore legitimate law and order?
The scientist who found a way to tally up global catches is an ocean advocate and a vocal critic of industrial fisheries. Now we have a treaty for the high seas — but does it go far enough?
There are two types of wildfire in the state, and they’re on the rise for different reasons. Each needs a distinct management approach, a researcher says.
Paleogenomic research has expanded rapidly over the past two decades, igniting heated debate about handling remains. Who gives consent for study participants long gone — and who should speak for them today?
The technology could transform how growers protect their harvests, by detecting plant diseases very early on. But the challenge is to develop tools that are as affordable as they are effective.
The way we see and describe hues varies widely for many reasons: from our individual eye structure, to how our brain processes images, to what language we speak, or even if we live near a body of water
There is no one prehistoric meal plan. A modern hunter-gatherer group known as the Hadza has taught researchers surprising things about the highly variable menu consumed by humans past.
Katherine Flegal was a scientist who found herself crunching numbers for the government, until one day her analyses set off a firestorm. What does she make of her decades as a woman in public health research?
In the US, people charged with a crime usually need to post a large cash bond to be released before trial — a system used barely anywhere else in the world. This doesn’t enhance public safety and causes great hardship to defendants and families. There’s a better way, researchers say.
This challenging phase of life may get a bad rap, but it’s also full of opportunity. A developmental neuroscientist shares what she’s learned from studies on young people’s risk-taking behavior, reasoning and more.
What would it take to create a truly intelligent microbot, one that can operate independently? A roboticist describes the fascinating minutiae and the medical jobs these tiny machines could do for us.
Urban activities — think construction, transportation, heating, cooling and more — are major sources of greenhouse-gas emissions. Today, a growing number of cities are striving to slash their emission to net zero — here’s what they need to do.
The world’s natural history collections hold billions of biological specimens, many of which still contain DNA. Scientists exploring these genetic repositories are gaining new, historical perspectives on how animals evolve.
Lower-income countries haven’t gotten an equal share of lifesaving coronavirus vaccines. Older, more familiar vaccine technologies may hold the key to more equitable use, says Maria Elena Bottazzi.
ACs and refrigerators help keep people safe — but they also further warm the planet. Scientists are working on eco-friendlier solutions as global demand for cooling grows.
NuqneH! Saluton! A linguistic anthropologist (and creator of the Kryptonian language, among others) studies the people who invent new tongues.
