Researchers have developed a liquid metal that breaks down carbon dioxide in the air, converting it from a climate threat into a valuable raw material.
The newfound — and at times quirky — shapes reflect the density of water surrounding submerged ice.
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.
A fat molecule's three long chains of carbon and hydrogen atoms repel water, stash energy and keep living things warm — even in the bitter cold.
Convection is a process that transfers heat through the movement of liquid or gas.
In physics, plasma refers to one of the four states of matter. In medicine, plasma describes the part of blood that ferries cells, nutrients and more throughout the body.
Aerosols are tiny bits of solids or drops of liquids suspended in gas. Aerosols include mist, fog and soot, as well as pollution from fossil fuels.
These specially grown threads of ice bend into curves, then spring back when released.
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
