New measurements of a weird but simple atom, one without a nucleus, suggest it may have unexpected properties. Scientists find this troubling.
Pour out liquid water into a solid ice tower. We outline the conditions you’ll need to turn this demonstration into a super-cool experiment.
Snot oozed by a marine tube worm can glow for up to 3 full days. The secret of how this works might lead to long-lasting lights that glow on and on.
Feared equipment shortages due to the COVID-19 pandemic have prompted research teams to develop novel technologies to help oxygen-starved lungs.
Making rock candy at home takes a lot more sugar than you might think. Why? This experiment will show you why.
Food scientists now show that adding these tiny plant particles to ice cream may delay the rate at which this treat melts into a soupy mess.
Sometimes a chemical reaction can take a while. If speed is needed, a catalyst can help.
The greenery can release chemicals into the air that react with combustion pollutants to make ozone. And trees release more of those chemicals where it gets really hot, a new study finds.
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.
