October 27, 2014
A living cell, from one point of view, is a sort of sprawling protein factory that can churn out thousands of different proteins to order. Prof. Roy Bar-Ziv of the Weizmann Institute’s Materials and Interfaces Department is building on the basic idea of creating “artificial...

October 27, 2014
You can see them on nature trails, carrying a smartphone in one hand and a large plastic bag in the other. These modern hunter-gatherers are after an all-too-common quarry: the trash left behind by others of the human species. Dr. Ron Milo of the Weizmann Institute’s Plant and En...

November 4, 2014
In high school, a “problem” is a question that a student is expected to solve within no more than 30 minutes and which has a single correct answer. The Physics and Industry program offered to high school students at the Weizmann Institute is an encounter with an entirely differen...

November 4, 2014
Bones break; it happens. It also happens that bones are one of the few organs that are able to regenerate. Those unfortunate enough ever to have experienced a broken bone know the procedure only too well: A physician physically “yanks” the bone – or, in the case of severe fr...

November 23, 2014
To divide or not to divide: This is one of the most crucial decisions in the life of a cell. A new Weizmann Institute of Science study, conducted in collaboration with Danish researchers, has revealed a previously unknown mechanism that is involved in the control of such decision...

November 16, 2014
The frustration is familiar: You buy a perfect, slightly hard avocado, mango or tomato, but by the time it ripens sufficiently to be eaten, it has developed soft rotten spots that force you to discard at least part of the fruit and wonder if you need to change your green...
https://wis-wander.weizmann.ac.il/life-sciences/“big-eaters”-get-makeover
December 7, 2014
When in the 1880s Russian zoologist Ilya Mechnikov first described large, voracious cells that devour bacteria and cellular debris – findings for which he later received a Nobel Prize – he called them macrophages, or “big eaters.” Although macrophages have since been assigned nu...
