Mar 22, 2020... REHOVOT, ISRAEL—March 22, 2020—A method for monitoring, identifying, and predicting where the coronavirus will spread has attracted considerable international interest. It was initiated and developed by scientists from the Weizmann Institute of Science, in collaboration with researchers from the Hebrew University of Jerusalem and Clalit Health Services and in coordination with Israel’s Ministry of Health. Other governments have now begun to implement the method, which is based on questionnaires for the general public and analysis of the data obtained from them. The questionnaires track the development of virus-induced symptoms, and the analysis relies on Big Data algorithms and artificial intelligence. Viral spread occurs in clusters of infection; thus, early identification of clusters may facilitate various actions aimed at slowing down the spread of the virus.

Brain tissue from genetically engineered mice. Neurons that express CRFR1 appear in green and those that release the neurotransmitter CRF are in red. The image was obtained with fluorescence microscopy
In addition to the classic stress response in our bodies – an acute reaction that gradually abates when the threat passes – our bodies appear to have a separate mechanism that deals only with chronic stress. These Weizmann Institute of Science findings, which recently appeared in Nature Neuroscience, may lead to better diagnosis of and treatment for anxiety and depression.

October is National Breast Cancer Awareness Month, and people across the world are helping raise awareness and support through runs, walks, events – and, at the Weizmann Institute of Science, through research.
Before breakthroughs in breast cancer research ever appear in the news or on the market, there are cadres of scientists working tirelessly to discover new ways to prevent, diagnose, and treat this all-too-common disease. Here are some of our advances over just the past year:
Sep 02, 2010... On her first tour of her freshman dorm at the University of California, Davis in the fall of 1992, neurophysiologist and science journalist Kirsten Sanford met an engineering student who talked to her about signing up for an electronic mail account—a term she had never heard before. At the time, the Internet was little more than green text on a black screen, and hardly anyone she knew used it. But Sanford was intrigued. “The idea that I could send messages immediately to people without having to stamp a letter was fascinating.”
Jun 17, 2009... REHOVOT, ISRAEL—June 17, 2009—Bacteria can anticipate a future event and prepare for it, according to new research at the Weizmann Institute of Science. In a paper that appeared in the June 17, 2009 issue of Nature, Prof. Yitzhak Pilpel, doctoral student Amir Mitchell, and research associate Dr. Orna Dahan of the Institute’s Department of Molecular Genetics, together with Prof. Martin Kupiec and Gal Romano of Tel Aviv University, examined microorganisms living in environments that change in predictable ways. Their findings show that these microorganisms’ genetic networks are hard-wired to “foresee” what comes next in the sequence of events and begin responding to the new state of affairs before its onset.

Even in 2020, with all we know about health and nutrition, heart disease is still the leading cause of death in America, accounting for one in four mortalities. Fortunately, the Weizmann Institute of Science is taking multiple approaches to understanding and treating this too-common killer. February is American Heart Month – and we’d love to share our very latest research with you.
While there are several vital heart-related projects underway at the Institute, the lab of leading researcher Prof. Eldad Tzahor recently made a significant breakthrough: discovering that a non-toxic dye actually helps repair damaged heart tissue, such as the scarring that occurs after a heart attack.

REHOVOT, ISRAEL—February 5, 2014—New findings in mice suggest that merely changing meal times could have a significant effect on the levels of triglycerides in the liver. The results of this Weizmann Institute of Science study, recently published in Cell Metabolism, not only have important implications for the potential treatment of metabolic diseases, they may also have broader implications for most research areas in the life sciences.

Yeast cells producing a bacterial symmetric protein complex with eight units. When it is not mutated (left), the complex diffuses freely inside the cell, but a single mutation (right) triggers its assembly into long filaments
The proteins in our bodies are social molecules. But now and again, new ties between proteins can get you into trouble. For example, when hemoglobin – the protein complex that carries oxygen in our blood – undergoes just one mutation, the complexes stick to one another, stacking like Lego blocks to form long, stiff filaments. These filaments, in turn, elongate the red blood cells found in sickle-cell disease. For over 50 years, this has been the only known textbook example in which a mutation causes these filaments to form. According to Dr. Emmanuel Levy and his group in the Weizmann Institute of Science’s Structural Biology Department, Lego-like assemblies should have formed relatively frequently during evolution, and so they asked: How easy is it to get proteins to stack into filaments? Their answer, which was recently published in Nature, may have implications for both biological research and nanoscience.

It’s news to no one that your body works differently when you’re awake and when you’re sleeping. But could the different states also affect how your body processes certain life-saving drugs? Researchers, reporting Friday in the journal Nature Communications, found that when it comes to cancer drugs, the answer may be yes.
Researchers at the Weizmann Institute discovered – by happy accident – that some of the body’s molecular functions during the day may interfere with the effectiveness of certain cancer medication. Specifically, they found that the normal day-time production of some steroid hormones in the body actually inhibited the work of epidermal growth factor (EGF) receptors – which are the proteins targeted by a class of anti-cancer drugs. Tumor cells plant these receptors on their surfaces to attract nutrients that help them survive and grow. Drugs, including the breast cancer agent lapatinib, can block these receptors on tumors, and such medications are a popular way to treat breast cancers expressing epidermal growth factor.
Mar 19, 2020... REHOVOT, ISRAEL—March 17, 2020—In light of the severe constraints in performing a sufficient amount of coronavirus tests in Israel, the Weizmann Institute of Science has decided to contribute significantly to the national mission and use its advanced laboratories to perform coronavirus tests. In parallel, Weizmann Institute scientists are developing an advanced and very efficient testing approach that has a significantly reduced risk.
