Recognition of the risks posed by UV rays has motivated scientists to study what’s going on in our cells when they’re in the sun—and devise modern ways to ward off that damage
A shiny new chemistry activity
Recipes for concrete that incorporate by-products from the coal and steel industries, like fly ash and slag, could reduce road salt–related cracking. Christopher Intagliata reports.
Volcanic springs and deep-ocean vents get new evidence
A flashy project from Science Buddies
New movies of drug proteins or photosynthesis in action, shot in millionths of a billionth of a second, show how the molecules work—or fail
Even in salmon season the bears eat lots of plants—and later gorge mostly on salmon brains
A purely scientific project
A promising treatment that uses MDMA could help people suffering with post-traumatic stress disorder
Researchers blocked from financial dealings in U.S., but sanctions may have little impact

Chemists will navigate molecular wagons along a tiny golden track
Industry players swear pot’s many chemicals work in concert, but most scientists hear a THC solo
Starting in the next century, atmospheric carbon levels could begin to approach those of hundreds of millions of years ago, and have their warming effect augmented by a brighter sun.
The mushroom cloud from the 22,000-pound air-blast bomb was meant to send a clear message
A tension-filled science activity
Efforts to harness the power of toxic chemicals and deadly organisms have been at the core of chemical and biological attacks throughout history. This package chronicles such incidents before and after Syria's recent alleged chemical weapon attack on civilians outside Damascus
Scientists have created hollow molecules to trap toxic gases such as sarin
