New method tracking single atoms may lead to improved drug design
Until now, scientists studying the workings of ultra-microscopic forms have had to rely on the scientific equivalents of still photos, something like trying to fathom driving by looking at a photograph of a car. Now, Prof. Irit Sagi and her team of the Structural Biology Department are using new and innovative methods developed at the Weizmann Institute to see real-time "video clips" of enzyme molecules at work. The resolution of these animated clips is so fine that the scientists are able to see the movements of individual atoms within the molecule.
The challenge facing the Weizmann team was to capture, step-by-step, the complex process -- the whole of which takes place in a tiny fraction of a second -- that an enzyme molecule goes through as it performs its work. Their pioneering method was published in Nature Structural Biology. It was hailed as the first of its kind, and a potentially important tool for biophysicists.

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
