Israel21c covers the Nancy and Stephen Grand Israel National Center of Personalized Medicine at the Weizmann Institute, including discussion with Dr. Berta Strulovici, the center’s founding director. The G-INCPM is already studying acute myeloid leukemia, soft-tissue sarcoma, and retinitis pigmentosa.
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.”
The lab of Prof. Alon Chen has found that, besides our classic stress response – an acute reaction that gradually abates when the threat passes – we appear to have a separate mechanism that deals only with chronic stress. The team found a new mechanism that apparently regulates the stress response. These findings may lead to better diagnosis of and treatment for anxiety and depression.
Our hearts mean many things: love, strength, loyalty. But even if we look at hearts from a purely biological perspective, they are still awesome – and complicated, particularly when it comes to disease. That’s why, for American Heart Month, we’d like to share some of the many approaches Weizmann Institute scientists are taking to fight heart disease.
Haaretz interviews Prof. Noam Sobel about his intensive research into the sense of smell, which - it turns out - informs every area of our lives, from what we eat to whom we love. Among other innovative studies, he is investigating whether odors can help people trust robots and whether smell is involved in repeated miscarriages.
Two new and powerful research methods – CRISPR gene editing and single-cell genomic profiling – have now been combined to produce a tool fine enough to enable scientists to observe life’s most nuanced processes. Prof. Ido Amit and his lab have so refined CRISPR that scientists can understand biological processes in shades of grey – not just black and white.
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.
Two new databases - WeizMass and MatchWeiz - created in the lab of Prof. Asaph Aharoni help scientists identify the majority of metabolites in a plant, including fruits such as tomatoes. This helps provide targeted nutritional information and reveals that biologically active plant substances are much more prevalent across the plant kingdom than was previously thought.
