    Rare Genetic Defect May Lead to Cancer Drug

    The path to understanding what goes wrong in cancer could benefit from a detour through studies of rare childhood diseases. Dr. Ayelet Erez explains that cancer generally involves dozens – if not hundreds – of mutations, and sorting out the various functions and malfunctions of each may be nearly impossible. Rare childhood diseases, in contrast, generally involve mutations to a single gene.

    Stressed Out from Birth: Mice Exposed to Prenatal Stress Are Predisposed to Eating Disorders Later in Life

    Stress affects the body and can trigger illness – from psychiatric disorders to heart disease. Humans are exposed to stress at different intensities throughout life: as children, in adolescence, and in old age. But when is the impact of stress on our systems most powerful? Many researchers maintain that the critical effect occurs prenatally, inside the womb. This hypothesis was, until recently, based mainly on statistical data indicating a correlation between stress during pregnancy and susceptibility to disease.

    Eat a Purple Potato If You Know What’s Good For You

    Are you ready for violet-colored potatoes? How about orange tobacco? Researchers at Israel’s Weizmann Institute of Science have figured out how produce betalain pigments in plants and flowers that don’t normally have them. If you’re thinking, “Who needs violet tomatoes?” you should know that red-violet and yellow betalain pigments contain healthful antioxidant properties. They’re also the basis for natural food dyes for products such as strawberry yogurt.

    New Israeli Research Into Genomes Sheds Light on Causes of Deafness

    Researchers on the quest to solve the puzzle of what causes deafness got one small step closer with the announcement that scientists at Tel Aviv University and the Weizmann Institute of Science have mapped a certain type of RNA (a molecule essential to the coding and expression of genes) that exists in close proximity to the genes related to hearing.

    Pancreatic Cancer is Often Deadly. But Recent Discoveries Are Starting to Unravel its Mysteries — And Raise Hope

    Pancreatic cancer is deadly: It’s difficult to detect and bedeviling to treat. Just 20 percent of patients survive a year after diagnosis. Less than 10 percent make it to the five-year mark. But recent discoveries — both in the lab and in patients — are raising hope. They’re still early stage. Yet they offer new insight into the causes and progression of the disease — and they may ultimately help doctors better detect, and treat, this difficult cancer.

    Bacteria Alert by Scientist

    The Israeli crystallographer, who shared the chemistry Nobel with Venkatraman Ramakrishnan and Thomas A. Steitz in 2009 for her work on ribosome, was delivering the 79th Foundation Day lecture on “Next Generation Environmental Friendly Antibiotics” at Bose Institute on Thursday. “Resistance to antibiotics is a real big problem to modern medicine. Multi-drug resistance has developed not because we use antibiotics, but because bacteria has evolved and uses mechanisms against other bacteria in their fight for resources,” Yonath said.
