Overturning Ideas on Cancer

Another advance in cancer research is featured on our website this week. Among other things, this one highlights the dangers of assuming causation from correlation. Prof. Dov Zipori and his team were looking at adult stem cells in the bone marrow. These hold a lot of potential for treating many kinds of disease but, like…

Does your face reveal what’s in your heart? It might – even more than you know. Take, for instance, a common group of birth defects – forms of a disorder called DiGeorge syndrome. Around one in 4000 is born with this syndrome, which arises from a deletion of a short segment of chromosome 22.  Among…

Math in Medicine

One of our constant themes is the innovative ways that tools and ideas from math and physics can lead to new insights in the life sciences. Take, for example, a recent study produced by a group that included a professor of mathematics, an oncologist who works in pharmaceutical research and has a Ph.D. in mathematics,…

Often, simply identifying the structure of a potential drug target protein and designing a molecule to block it are not enough. Just ask Prof. Irit Sagi, a chemist turned biology researcher, who recently developed a clever technique for directing the body to design its own protein-blocking molecules. Sagi studies an enzyme called matrix metalloproteinase 9…

Today’s science news from the Weizmann Institute covers research in neurobiology, environmental science and cancer immunology. • In the first, scientists identified a likely biological marker for autism that shows up even in very young children. Diagnoses of autism are generally not possible so early, as the signs typically appear gradually throughout the first 3-4…

This week’s Weizmann news stories: A “steam release valve” for inflammation, a “brake” for cell division and an “amplifier” for quantum signals. The steam release valve mechanism also involves an amplifier – one that ramps up the inflammation signal in response to viral attack on a cell. When the signal reaches its peak, it trips…

New research at the Institute sheds some light on a protein that could make it harder for overweight people to stick to a diet. That protein helps regulate the effects of leptin – a hormone that reduces appetite and increases physical activity. People missing the leptin gene are invariably obese. It turns out, however, that…

Three news items were posted on our site today. The first is on two papers by a group in Spain. Normally we don’t publicize papers that are not written by Institute scientists, but these are a special case. They appear to have clinched the claims of a Weizmann scientist that one can treat stroke and…

Two Ounces of Prevention

Two recent papers to come out of the Weizmann Institute have possible medical applications — one in preventing pregnancy, the other in preventing the deadly effects of nerve gas. The first might give pause to those among us who are “believers” in antioxidants. It seems that those “nasty” molecules they eliminate — reactive oxygen species…
