Dr. Michal Irani

A Visual Window into Space and Time

01.01.2002

People and Events›People

Whether spellbinding or tedious, a video film seems like a simple sequence of pictures. Yet it encompasses often-overlooked spatial and temporal information. Dr. Michal Irani of the Weizmann Institute's Computer Science and Applied Mathematics Department develops advanced methods for extracting and analyzing this information

Prof. Yaron Silberberg

Secrets of the Third Harmony

People and Events›People

Prof. Yaron Silberberg, the Head of the Weizmann Institute’s Physics of Complex Systems Department, has a vision: to take a penetrating look inside the most minuscule of objects.

The Chemistry of Vision

01.01.2002

People and Events›People

It was long believed that the rotation of the "retinal molecule" was the first stage in vision. However, Prof. Mordechai Sheves of the Weizmann Institute’s Organic Chemistry Department revealed that the retinal protein’s structure changes even when rotation of its internal retinal molecule is prevented, suggesting that the visual process starts even earlier.

Prof. Avigdor Scherz

Light Harvesting

01.01.2002

People and Events›People

Chlorophyll molecules have been selected by nature over billions of years of evolution to help plants and certain bacteria utilize sunlight to drive the production of carbohydrates. Prof. Avigdor Scherz of the Weizmann Institute’s Plant Sciences Department and Prof. Yoram Salomon of the Biological Regulation Department have recently prepared chlorophyll derivatives that might also help save the eyesight of humans.

Prof. Amiram Grinvald

In the Eye of the Beholder

01.01.2002

People and Events›People

What happens in our brains while listening to music or deciphering dual optical illusions, like the one illustrated above? Prof. Amiram Grinvald and his research team at the Weizmann Institute’s Neurobiology Department have directly observed the first clues to the neuronal basis of the truism “It’s all in the eye of the beholder.” Sensory perception, the researchers proved, is a dual process.

Raising children is undoubtedly among the most rewarding of projects, and yet also demanding and uncertain. In this respect, it greatly resembles scientific research.

A Century-Old Challenge

One of Hilbert's unsolved problems to this day is the research focus of Prof. Sergei Yakovenko of the Weizmann Institute's Mathematics Department.

Electrons on the Map

01.11.2001

People and Events›People

When a single electron moves around this hole, the exciton that forms is equivalent to a neutral hydrogen atom. Prof. Israel Bar-Joseph discovered that under certain conditions a second electron may join the exciton, creating a charged exciton equivalent to a hydrogen ion. More recently, he used the special properties of these charged excitons to map with great precision the position of electrons in a semiconductor.

What's a Cell to Do?

01.11.2001

People and Events›People

In its earliest stages of development, the embryo consists of a small number of cells. As these cells divide and multiply, the embryo grows. But how do the lungs, heart, and other organs, so striking in their architectural waltz of form and function, develop? How do certain cells develop into muscle tissue while others "choose" to become nerve or blood cells?
