Research shows that human immune system uses ancient family of cell death proteins also found in bacteria

The human immune system, that marvel of complexity, subtlety, and sophistication, includes a billion-year-old family of proteins used by bacteria to defend them ....

Advanced mouse embryos grown outside the uterus

E-Mail
To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of embryonic development for nearly 100 years. Prof. Jacob Hanna of the Weizmann Institute of Science and his group have now accomplished this feat. The method they created for growing mouse embryos outside the womb during the initial stages after embryo implantation will give researchers an unprecedented tool for understanding the development program encoded in the genes, and it may provide detailed insight into birth and developmental defects as well as those involved in embryo implantation. The results of this research were published in ....

Evolved to stop bacteria, designed for stability

E-Mail
Connections are crucial. Bacteria may be most dangerous when they connect - banding together to build fortress-like structures known as biofilms that afford them resistance to antibiotics. But a biomolecular scientist in Israel and a microbiologist in California have forged their own connections that could lead to new protocols for laying siege to biofilm-protected colonies. Their research was published in the
Proceedings of the National Academy of Sciences (
PNAS), USA.
This interdisciplinary collaboration began with a lecture given at the Weizmann Institute of Science in the Life Sciences Colloquium. Prof. Dianne Newman of the California Institute of Technology was the speaker, and the Institute s Prof. Sarel Fleishman, of the Biomolecular Sciences Department, decided to attend, even though the lecture had no immediately apparent bearing on his own research. Newman described an enzyme she had discovered that could interrupt the metabolism of the biofi ....

Stress Response Protein Links Inflammatory Disease to Colon Cancer

Weizmann Institute of Science
The findings might help identify those at extra risk of this cancer and develop means of prevention
Inflammation promotes some of the deadliest cancers. In the colon, inflammatory bowel disease is well known to be associated with higher-than-average rates of malignancy. Nevertheless, the developing tumor is commonly diagnosed only when it has already advanced or even metastasized, possibly because the early symptoms of malignancy are often mistakenly ascribed to a flare-up of intestinal inflammation. Weizmann Institute of Science researchers have now revealed a molecular missing link between chronic gut inflammation and cancer. This revelation may help develop ways of preventing colon cancers in people with inflammatory diseases of the intestines. ....
