    Artificial Sweeteners Hit a Sour Note

    Artificial sweeteners have long been promoted as diet and health aids – but Weizmann scientists have discovered that such products may be causing our gut bacteria to trigger harmful metabolic changes. In other words, the sweeteners may be leading to the very diseases – such as obesity – they were supposed to help prevent.

    “To Understand the Principles of Life”: The Journey of Prof. Ada Yonath from Ribosomes to the Nobel Prize

    Prof. Ada Yonath believed that the ribosome was crucial and must be studied - despite the fact that the world's best labs had given up trying to do so. She pursued her idea over decades, and was the first scientist to crystallize the ribosome, later deciphering its structure—and, in 2009, she became the fourth woman in history to win the Nobel Prize in Chemistry.

    Blood Sugar Levels in Response to Foods Are Highly Individual

    Prof. Eran Segal and Dr. Eran Elinav's Personalized Nutrition Project has new results that underscore the importance of a personalized diet, prepared based on complex factors such as your gut microbes and lifestyle. The foods that raise your blood sugar levels may not be what you'd expect, and responses differ surprisingly from person to person.

    Is Your Microbiome Undermining Your New Year's Resolution?

    The perennially most popular New Year's resolution is to lose weight and be healthy – and yet most people fail. But why? Thanks to the Weizmann Institute, we now have the answer. And it's not your fault; it's your microbiome's. The Personalized Nutrition Project's surprising results show that what you eat does matter – but maybe not in the way you think.

    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.

    UN Talks Superbugs; Weizmann Takes Action

    In September 2016, for only the fourth time in history, the UN General Assembly is talking about a global health crisis. Superbugs – microbes that are resistant to antibiotics – are a major threat not just to health, but also the economy and security. Fortunately, Weizmann scientists are on the case.

    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.
