A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.
An electrode’s name depends on the circumstances. Confused? It may help to consider which electrochemical reaction is natural — and which is not.
A fluorescent polymer duo boosts the efficiency of solar cells. One day this material may coat your jacket, hat or backpack to provide power on the go.
Baking soda volcanoes are a fun demonstration, and with a few tweaks they can be an experiment, too
New measurements of a weird but simple atom, one without a nucleus, suggest it may have unexpected properties. Scientists find this troubling.
Here’s how to freeze a soap bubble in midair. Warning: The environment needs to be frosty, and even then it can take a certain amount of trial and error.
A special coating that conceals temperature information from heat-detecting cameras might someday be used as a privacy shield.
Scientists at the Georgia Institute of Technology built a 'smart' surface on which to play table tennis. It can track the location, speed and direction of the ball.
Heat can move across a vacuum if the span is small enough. As in really, really small. In a new experiment, the gap was only a few hundred nanometers.
