Our livers perform a host of vital functions, including clearing our bodies of toxins and producing most of the carrier proteins in our blood. Weizmann researchers have now shown that the liver’s amazing multitasking capacity is due at least in part to a clever division of labor among its cells. In fact, they say, “We’ve found that liver cells can be divided into at least nine different types, each specializing in its own tasks.”
As Nature World News reports, Weizmann Profs. Lia Addadi and Steve Weiner have found that sea urchins form their spines in a very different way than scientists imagined: they "drink" seawater to get the crucial calcium ions.
The fine art of mixing drug cocktails - such as for cancer treatment - is incredibly complicated, especially once you get into three or more ingredients. The numbers of possible interactions and side effects are virtually infinite. Now, a new model from the lab of Prof. Uri Alon lets scientists compare combinations of drugs to determine which work well together, and with the fewest side effects. This is a major step forward in personalized medicine.
Following up on earlier research - and using technologies that did not exist then - Profs. Lia Addadi and Steve Weiner answered long-held questions: where do sea urchins get the calcium ions they need to build their spines? The answer: they "drink" sea water, even as larvae. And it turns out that other organisms use the same surprising process.
Dr. Sarel Fleishman studies how proteins "mate," or fit together – and, in fact, created his own method that lets scientists change the surface of proteins so that they mate with other proteins of the researcher's choice. This technique could lead to new treatments aimed at viruses, bacteria, and cancer.
Dr. Eran Elinav and Prof. Eran Segal developed a method of analyzing gut microbiota, enabling them to determine the foods that are healthier for each individual, based on how the bacteria metabolize the food. Now, as Globes reports, the method is being commercialized: startup DayTwo is bringing personalized nutrition home.
The Wall Street Journal reports on research by Weizmann's Dr. Gad Asher that “shaved days off mice’s recovery from a simulated transatlantic flight.” The work could lead to ways of treating jet lag post-flight with low-oxygen treatments.
The low pressure in airplanes can make traveling unpleasant – but it could also ease jetlag, finds Dr. Gad Asher. Every cell in the body contains a circadian clock, and when these clocks are disrupted, imbalances result. Dr. Asher’s findings could affect how airlines moderate cabin pressure. He and his team are now seeking ways to help travelers.
In September 2016, for only the fourth time in history, the UN General Assembly is talking about a global health crisis. Superbugs – microbes that are resistant to antibiotics – are a major threat not just to health, but also the economy and security. Fortunately, Weizmann scientists are on the case.
Prof. Noam Sobel, who notably found that women’s tears reduce testosterone in men, has found a way to preserve and store tears. As Scientific American reports, he is building a cryogenic “tear bank,” which will allow researchers worldwide to study the difference between emotional and nonemotional tears, whether tears affect appetite, and more.
