    How Disrupting Your Gut’s Rhythm Affects Your Health

    The Wall Street Journal reports on “tour de force” research by Dr. Eran Elinav and Prof. Eran Segal that “sheds light on how eating and sleeping habits can contribute to disease by disrupting the bacteria in the digestive tract.” This is another major step toward personalized nutrition and personalized medicine.

    Gene Analysis Adds Layers to Understanding How Our Livers Function

    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.”

    StemRad’s Cosmic Ray Suit, Developed by Weizmann PhD, Set for Mars Trial

    Oren Milstein, who holds a PhD in immunology from the Weizmann Institute, is cofounder of StemRad - a company that has developed an innovative spacesuit that protects against cosmic rays, and is intended for use on trips to Mars. The Israel Space Agency and the Ministry of Science, Technology, and Space and the German Aerospace Center are launching the suit as part of the next trial flight of NASA's Orion satellite.

    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.

    Scientists Identify a Viral Communication System

    The Scientist reports on research from the lab of Prof. Rotem Sorek, who discovered that viruses leave “messages” for other viruses, enabling subsequent generations to decide whether to stay quiet or infect the host. The study has been called “annoyingly good.”

    White Blood Cells Get Pushy to Reach Infection

    How do white blood cells - the immune cells that race to the sites of infection and inflammation - actually get to their targets? The research of Prof. Ronen Alon has revealed that the white blood cells actually force their way through the blood vessel walls to reach the infection, creating large holes. This understanding could aid in cancer research.

    Viruses Overheard Talking to One Another

    For the first time, viruses have been found to communicate with one another, leaving short “posts” for kin and descendants. The messages help the viruses reading them to decide how to proceed with the process of infection.

    How Immune Cells Squeeze Through Blood Vessel Walls

    Cosmos reports on new research from Prof. Ronen Alon’s lab that reveals how immune cells enter - and leave - the bloodstream. It has long been known that they can do this, but not how. The findings are particularly relevant to cancer research, as tumor cells are less able to infiltrate the bloodstream.

    Circadian Rhythms and the Microbiome: Disrupting Daily Routine of Gut Microbes Can be Bad News for Whole Body

    Salon reports on findings from the lab of Prof. Eran Elinav that shows that the "gut microbiota changes location within the gut, and changes its metabolic outputs over the span of the 24-hour day." The story puts the research in context, explaining the role of these microbiota and their importance to our health.

    Why Yo-Yo Dieters Often Can’t Keep the Weight Off

    People all over the world repeatedly go through the long, frustrating, defeating struggle known as "yo-yo dieting": they lose weight, only to gain it again, over and over (and over). Now, new research from Dr. Eran Elinav and Prof. Eran Segal shows why: the gut microbiome keeps resetting the body to gain weight.
