We now know how insects and bacteria control ice

Contrary to what you may have been taught, water doesn't always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is ...

How nerve cells control misfolded proteins

Researchers have identified a protein complex that marks misfolded proteins, stops them from interacting with other proteins in the cell, and directs them toward disposal. In collaboration with the neurology department at ...

Toxin-spewing bacteria decoded

Scientists at Emory University School of Medicine have identified a central regulator of toxin production in the bacterium C. difficile, the most common cause of healthcare-associated infections in the United States. C. difficile ...

From mirror-image biology to enhanced therapeutic proteins

Scientists from the German Cancer Research Center (DKFZ) have succeeded in reconstructing biomolecules in their mirror-image form. The researchers' goal is to create a mirror-image artificial protein synthesis system. Their ...

How antifreeze proteins make ice crystals grow

Bacteria, plants, insects and fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, a German-Israeli research team has confirmed that these proteins ...
