    Artificial Sweeteners May Disrupt Body's Blood Sugar Controls

    <em>The New York Times</em> reports on bombshell research from Dr. Eran Elinav and Prof. Eran Segal. The two scientists found that gut microbiota can trigger metabolic changes after exposure to artificial sweeteners, potentially leading to obesity and diabetes – conditions that diet drinks and foods with sweeteners are supposed to help us avoid.

    Immunotherapy: Cancer Treatment Based on Weizmann Research is Saving Lives

    Weizmann Institute basic research is, yet again, behind the headlines: a new blood cancer therapy that uses one's own immune system to defeat the disease is stunning clinicians and giving patients hope. Trials in the U.S. have had amazing results, with critically ill leukemia patients now in remission. The breakthrough is based on decades of research by Weizmann's Prof. Zelig Eshhar, who is now working to adapt his method to other forms of cancer.

    How a Bacterial Cell Recognizes Its Own DNA

    Our immune systems fight bacteria – but did you know that bacteria have immune systems, too? And how does the bacterial immune system distinguish between its own DNA and that of foreign invaders, so that it knows what to fight? The answer, revealed by a Weizmann Institute and Tel Aviv University team, involves a complex, multi-stage process.

    Programmed Proteins Might Help Prevent Malaria

    Malaria is still a global scourge, killing mostly children in tropical regions. Developing an inexpensive vaccine that can stay stable without refrigeration has so far eluded scientists. Now, Dr. Sarel Fleishman's lab has reprogrammed proteins in such a way that they could lead to a new and effective vaccine.

    Stem Cells Might Heal Damaged Lungs

    The insight that bone marrow and lung stem cells are quite similar led Prof. Yair Reisner and his team to investigate whether transplant methods used for bone marrow might also work for treating lung diseases such cystic fibrosis and asthma. When mice with lung damage were given the new stem cell treatment, their lungs healed and breathing improved.

    Science Tips, September 2015

    Three updates from the Weizmann Institute: discovering how the tiny, beautiful sea sapphire changes color – and even becomes invisible; using light to get nanoparticles to self-assemble could lead to rewritable paper, contaminant removal, and drug delivery; measuring how fast bacteria grow sheds new light on how our microbiome is tied to our health.

    Gut Microbes Contribute to Recurrent "Yo-Yo" Obesity

    Yet again, new research from Dr. Eran Elinav and Prof. Eran Segal is making global headlines and potentially changing lives. Most people have experienced the rebound effect of dieting - losing weight only to regain it, and then some. Now the Weizmann team has determined why this happens, and has identified potential solutions.
