What he found was a protein that seemed to prevent ice crystals from growing. As studies of these intriguing "anti-freeze" proteins progressed, they were discovered in many more organisms - fish, insects, bacteria, fungi and plants that have to survive freezing temperatures. Many of our more hardy frost-surviving vegetables and even our humble lawns produce these ice structuring proteins when there is a harsh frost...

Scientists in the US discovered that when mice detect specific proteins found in cat saliva and rat urine they react with fear. These proteins, called Mups, act on cells in a special sensory organ in the mouse, called the vomeronasal organ.

We haven't even solved the sequence-to-protein-folding problem, which is an essential first step to executing Kurzweil's clueless algorithm. And we have absolutely no...

Scientists gave mice drinking water laced with three amino acids. They said the rodents lived significantly longer than other mice fed a normal diet.

The study in Nature Communications showed that without their natural "magnetoreception" protein, the flies did not respond to a magnetic field - but replacing the protein with the human version restored the ability. Despite much controversy, no conclusive evidence exists that...
