Questioning conventional understanding of antifreeze proteins

Scientists have discovered that an ice-binding protein (fcIBP) from sea ice microalga does not fit in the conventional classification of ice-binding proteins, suggesting unknown mechanisms behind its antifreeze property. ...

How antifreeze proteins stop ice cold

How do insects survive harsh northern winters?  Unlike mammals, they don't have thick coats of fur to keep warm.  But they do have antifreeze. Antifreeze proteins (AFPs) prevent ice from forming and spreading inside their ...

Tiny satellite's first global map of ice clouds

Looking at Earth from the International Space Station, astronauts see big, white clouds spreading across the planet. They cannot distinguish a gray rain cloud from a puffy white cloud. While satellites can see through many ...

Chemical composition of aircraft exhaust aerosols investigated

Can aircraft pollutant emissions be reduced by using biofuels? And what influence does an alternative fuel have on the formation of contrails? In mid-January, a joint German Aerospace Center (DLR) and US space agency NASA ...
