    Prof. Michal Schwartz Will Change Your Mind

    Prof. Michal Schwartz's new book shares her breakthrough discovery that the immune system and brain communicate, and how this could lead to slowing – even reversing – brain aging and neurodegeneration.

    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.

    How Disrupting Your Gut’s Rhythm Affects Your Health

    <em>The Wall Street Journal</em> 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.”

    The Brain’s Rejuvenating Cells

    Alzheimer’s disease is a neurodegenerative disease manifested by various neuronal pathological processes and a significant decline in brain function. Aggregates of beta-amyloid protein (“plaques”) accumulate within and between brain cells. Due to both structural changes and the weakening of chemical communication pathways, the junctions of neuronal networks (synapses) are lost. In addition, the cytoskeletal proteins of the axons lose their normal structure, impairing their function and causing massive neuronal death.

    The Dust Storm Microbiome

    Israel is subjected to sand and dust storms from several directions: northeast from the Sahara, northwest from Saudi Arabia, and southwest from the desert regions of Syria. The airborne dust carried in these storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms. Some of these bacteria might be pathogenic – harmful to us or the environment – and a few of them also carry genes for antibiotic resistance.

    How Malaria Tricks the Immune System

    Global efforts to eradicate malaria are crucially dependent on scientists’ ability to outsmart the malaria parasite. And Plasmodium falciparum is notoriously clever: it is quick to develop resistance against medications and has such a complex life cycle that blocking it effectively with a vaccine has thus far proved elusive. In a new study reported in Nature Communications, researchers at the Weizmann Institute of Science, together with collaborators in Ireland and Australia, have shown that P. falciparum is even more devious than previously thought: not only does it hide from the body’s immune defenses, it employs an active strategy to deceive the immune system.
