January 5, 2004
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 Departm...

Giving birth has never been easy. Nature seems to have decided that whoever wants to procreate should put in an effort. Sometimes the process of birth, the physical separation from offspring, is so difficult that a mother needs a helping hand. And humans are not alone in this tra...

March 9, 2000
Weizmann Institute scientists have made an important step towards harnessing organic molecules to future electronics. Reported in the March 9th issue of Nature, their approach places common semiconductor-based devices -- for the first time ever -- under the control of organic mol...

March 6, 2000
Weizmann Institute scientists have succeeded in stopping the progressive loss of eyesight in animals with a glaucoma-like disease. Their innovative study, reported in the March 6, 2001 issue of the Proceedings of the National Academy of Sciences U.S.A., suggests that Copaxone, a...

April 15, 2004
Kidney disease may affect as many as one in twelve people, and causes millions of deaths each year. Currently, the diagnosis of kidney function relies mainly on blood and urine tests, an indirect means of figuring out how well they’re working. Standard MRI scanners, u...

April 15, 2004
The scanning electron microscope (SEM) has been a basic research tool for fifty years, and for those fifty years, scientists have been looking for better ways to observe biological samples under its beam. The problem is that the viewing chamber of the SEM must contain...

February 28, 2000
Weizmann Institute scientists propose a model regulating cell adhesion -- central to embryonic development, cellular movement, and communication 'Hard times,' or more specifically, exposure to rigid environments, enhances the tendency of cells to form tight adhesions and com...
