    Safer Chemo, Thanks to Israeli Math

    In a remarkable example of cross-disciplinary application, Weizmann Institute mathematicians and others developed a new model for evaluating infection risk for chemotherapy patients. The work could lead to a more individualized approach to cancer treatment.

    New Diagnostic Test Distinguishes Bacterial from Viral Infections

    Israeli startup MeMed is receiving funding and accolades for a test that determines whether an infection is bacterial or viral, thus helping prevent antibiotic overuse. As Iton Gadal reports, the test is already being used by hospitals in the EU, Switzerland, and Israel. MeMed was founded by Eran Eden, who received a doctorate from Weizmann.

  • Nobel for Antibiotics Tool

    Prof. Ada Yonath of the Weizmann Institute was one of three scientists awarded the 2009 Nobel Prize in Chemistry. Her work to decipher the structure and function of the ribosome has helped lead to new antibiotics, among other breakthroughs.

    On the Probiotic Trail

    The probiotics research of Dr. Naama Geva-Zatorsky helped her win a prestigious UNESCO-L'Oreal international fellowship. But that's just the beginning of what promises to be a long career, as ""there are 10 times more bacteria than human cells in the body,"" influencing everything from health to weight to depression.

    Bacteria Engineered to Make Sugar From Carbon Dioxide and Feed World

    All forms of life “fix” carbon: adding energy to CO2 to, as The Jerusalem Post reports, “turn it into the sugars that are the required starting point needed for life processes.” Prof. Ron Milo has engineered bacteria to improve carbon fixation, which could help meet the need to supply more food to more people, while using less fossil fuel and taking up less land.

    You're Probably Not Mostly Microbes

    <em>The Atlantic</em> reports that new findings by Dr. Ron Milo overturn long-held ideas about us and our microbes. The generally accepted microbe-to-person ratio was 10:1, meaning that we would be exponentially outnumbered by our bacteria. But Dr. Milo and his team have found that the proportion is more like 1:1 – and that just using the restroom can change the balance.

  • ""Alien"" Arsenic Life Discredited

    <em>Discover</em> magazine's year-end listing of the top 100 stories in science includes research from Weizmann's Prof. Dan Tawfik and team, who were able to help discredit an earlier claim that a bacterium had been found that could exist on arsenate rather than phosphate, like all other life.

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

    <em>Salon</em> 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.

    Israeli Startup DayTwo Offers Personalized Nutrition

    Dr. Eran Elinav and Prof. Eran Segal developed a method of analyzing gut microbiota, enabling them to determine the foods that are healthier for each individual, based on how the bacteria metabolize the food. Now, as <em>Globes</em> reports, the method is being commercialized: startup DayTwo is bringing personalized nutrition home.

  • Teaming up antibiotics to fight deadly superbugs

    Nobel laureate Prof. Ada Yonath led a team of American and Israeli researchers to study antibiotic-resistant ""superbugs."" The group found that two commonly used antibiotics, largely ineffective on their own, are powerful enough to treat such infections when used in combination. Antibiotic resistance is, however, on the rise.
