For the first time, scientists have shown that a new kind of genetic engineering can crash populations of malaria-spreading mosquitoes.

We speak with the Nobel Prize-winning founder of behavioral economics about the new — and last — version of his classic book, Nudge.

The authors say their research is the first to show an empirical link between tipping and forced friendliness to sex harassment. More than 70% of female restaurant workers report being harassed.

With much of the U.S. already sweltering this summer, even avid runners, hikers and bikers are wilting. We've got 10 strategies from experts on how to enjoy hot weather exercise without keeling over.

On mountaintop glaciers of Alaska, Washington and Oregon, billions of tiny black worms are tunneling upward to the barren, icy surface. What lures them, and how do they survive the frozen depths?

Clearing natural forests in Brazil in order to grow crops like soybeans has actually made it harder to grow those crops. That's because deforestation makes the weather hotter and drier.

A swimmer of any skill level might need your help, and preventing a drowning takes closer supervision of the kids than you might think. The distress signs can be subtle and quick.

It's a smackdown of one space monster by another: Scientists have made unprecedented observations of two black holes gobbling two neutron stars — among the weirdest space collisions ever detected.

Vaccines may not be as effective for those who are immuno-compromised. Protecting them needs to be made a top priority, says researchers — to keep them safe and to slow the emergence of variants.

Researchers have found hundreds of baby dinosaur bones in the Alaskan Arctic, suggesting that dinosaurs may have lived at cold northern latitudes year-round.

Scientists caution that as the planet warms, more Americans could be exposed to disfiguring varieties of the Leishmania parasite. Overtreatment can be a problem, too, experts warn.

Potentially, observers in plenty of star systems could have detected Earth sometime in the last 5,000 years. More stars will soon move into positions that would let them see our planet.

More contagious than other variants, and maybe more likely to cause severe disease, Delta is spreading so fast in the U.S. it could cause another surge this summer or fall, according to new research.

We speak with one of the leading scholars of automation about its evolving impacts on society.

A new CDC study finds that people who provide unpaid care for their children or adult loved ones are twice as likely as noncaregivers to have experienced depression or anxiety, or thoughts of suicide.
