Proteins, it appears, have taken Frank Sinatra's "I Did It My Way" close to heart. A new study published in the current issue of Proceedings of the National Academy of Sciences (PNAS) reveals how single proteins, each a few nanometers (billionths of a meter) long, fold to assume their final shape. It shows that even proteins having the same final shape achieve it by taking different routes.

Our planet is bombarded every second with a large number of chargeless, seemingly massless, particles that originate in nuclear fusion reactions that power the sun. They're called neutrinos.

Genetics
In at least one type of endeavor, humans can’t even begin to compete with their best friends. Dogs can be trained to sniff out drugs and explosives or to track down a crime suspect by smell. Why can’t we do the same? Scientists from the Weizmann Institute of Science and the Max Planck Institute for Evolutionary Anthropology propose an explanation for this ancient quandary.

Ten construction workers will often get a job done faster than one.  But in digging a deep well, for instance, ten workers are a waste of human resources: the diggers can't work simultaneously, as the second worker isn't able to start digging until the first one has finished, and so on.

A team of Weizmann scientists has gained new insight into the effects of a newly approved drug, rivastigmine, in treating Alzheimer’s disease, a debilitating brain disease causing memory loss in around 10% of the elderly. The study was published in the American Chemical Society journal Biochemistry.

Fifty years after the discovery of the structure of DNA, a new use has been found for this celebrated molecule: fuel for molecular computation systems. The search, conducted by scientists at the Weizmann Institute of Science, will appear in this week's issue of Proceedings of the National Academy of Sciences USA (PNAS).

The secret to its strength is a ring   Weizmann Institute scientists have found what makes the bacterium Deinococcus radiodurans the most radiation-resistant organism in the world: The microbe's DNA is packed tightly into a ring. The findings, published in the January 10 issue of Science, solve a mystery that has long engaged the scientific community.
