Searching for solid ice as scientists freeze in to study a warming arctic
A ship of researchers is crossing the Arctic for a year attached to an ice floe. But finding the right chunk of sea ice was a challenge, in part because warmer temperatures are making it thinner.
A Beautiful World: Molecules, the architecture of everything
In his highly anticipated sequel to The Elements, Theodore Gray demonstrates how the elements of the periodic table combine to form the molecules that make up our world.
Study suggests controversial pesticides may pose risks to fish populations, too
New evidence from Japan's Lake Shinji suggests that the widely used family of pesticides called neonicotinoids, already controversial for harming pollinators, could pose risks to fish as well.
Secret Air Force space plane lands after more than 2 years in orbit
The X-37B, launched in September 2017, has returned to Earth. It was the fifth acknowledged mission for the vehicle since 2010, but details of its mission are being kept under wraps.
Itty-bitty satellites take on big-time science missions
CubeSats are only about twice the size of a Rubik's Cube. Once dismissed as tools for students learning the principles of aerospace engineering, they're now being used for more sophisticated missions.
The placebo effect works and you can catch it from your doctor
Doctor-patient interactions can make a big difference to the effectiveness of treatments. In a new study, even a fake pain treatment helped when doctors believed it was real.
Most U.S. dairy cows are descended from just two bulls - and that's not good
The drive to produce more milk has had an unsavory side effect: Cows have become more genetically similar and less fertile. Now scientists are trying to recover valuable genetic variation that was lost over the past few decades.
What's behind the research funding gap for black scientists?
Black scientists more often seek grants for community health studies, but molecular-level research proposals win more funding. More diversity throughout the process could help close the gap, says NIH.
