New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...

Hot stuff: Lab hits milestone on long road to fusion power

With 192 lasers and temperatures more than three times hotter than the center of the sun, scientists hit—at least for a fraction of a second—a key milestone on the long road toward nearly pollution-free fusion energy.

Chemists discover new way to harness energy from ammonia

A research team at the University of Wisconsin-Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels.

A solar cell that does double duty for renewable energy

In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun's energy through "water splitting," an artificial photosynthesis technique that uses sunlight to generate hydrogen ...
