Pee power: Urine-loving bug churns out space fuel

Scientists on Sunday said they had gained insights into a remarkable bacterium that lives without oxygen and transforms ammonium, the ingredient of urine, into hydrazine, a rocket fuel.

Eliminating tooth decay: Breakthrough in dental plaque research

Dutch professors Bauke Dijkstra and Lubbert Dijkhuizen have deciphered the structure and functional mechanism of the glucansucrase enzyme that is responsible for dental plaque sticking to teeth. This knowledge will stimulate ...

Antifreeze proteins can stop ice melt, new study finds

The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio University and Queen's University study published today ...

Space station crew cultivates crystals for drug development

Crew members aboard the International Space Station will begin conducting research this week to improve the way we grow crystals on Earth. The information gained from the experiments could speed up the process for drug development, ...

Biology rides to computers' aid

Photonic crystals are exotic materials with the ability to guide light beams through confined spaces and could be vital components of low-power computer chips that use light instead of electricity. Cost-effective ways of ...

A close up look at how bacteria make ice

(Phys.org)—A combined team of researchers from Germany and the U.S. has taken a closer look at a type of bacteria that is able to cause ice to form, sometimes even under conditions above the normal freezing point.

Cornell researchers reveal structure of key protein

(PhysOrg.com) -- For the first time, researchers -- all Cornell scientists -- have characterized the structure of a protein that belongs to certain enzymes that are essential for proper functioning in all life forms, from ...
