Could life exist in molecular clouds?

Our search for life beyond Earth is still in its infancy. We're focused on Mars and, to a lesser extent, ocean moons like Jupiter's Europa and Saturn's Enceladus. Should we extend our search to cover more unlikely places ...

Fuel injection helps reduce magnetic island instabilities

Fusion is a non-carbon-based process for energy production, where lighter atoms fuse into heavier ones. Fusion reactors operate by confining a "soup" of charged particles, known as a plasma, within powerful magnetic fields. ...

Testing space batteries for cleaner skies

Engineers descended into bunkers to test space batteries to destruction – through overheating, overcharging, short circuits and even by shooting them with bullets. The three-year test campaign is helping assess the risk ...

Artificial enzymes to reduce carbon dioxide emissions

Enzymes are biological catalysts that accelerate chemical reactions, such as the conversion of gaseous carbon dioxide (CO2) into carbonates. Carbonates are the basic component of coral reefs, mollusc shells, geological platforms ...

Dust-plumes power intercontinental microbial migrations

Along with pollutants from Asia, transpacific dust plumes deliver vast quantities of microbes to North America, according to a manuscript published online ahead of print in the journal Applied and Environmental Microbiology.
