    Divine Secrets of the Ant Sisterhood

    Ants are altruistic and cooperative, but how do they communicate and assign roles? A Weizmann team is using tools from information theory, statistical and theoretical physics, computer science, systems biology, neuroscience, and biology to investigate.

    Rethinking Lymphatic Development

    Lymphatic vessels were first described by Hippocrates; centuries later, we're still learning about them. Weizmann's Dr. Karina Yaniv recently discovered that the lymphatic system does not develop as previously thought. Interestingly, says The Scientist, after all these years, three other studies on lymph vessel origin came out at the same time.

    Resolving a Lymphatic Riddle

    For more than a century, scientists have debated how the lymphatic system arises. Now that question has been answered, as Weizmann's Dr. Karina Yaniv has revealed how the system develops in the embryo, and – in a world's first – grown lymphatic cells in the lab. Besides solving this long-standing puzzle, her work can provide important insights into disease.

    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.

    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.

    Ants in the Lead

    As the old song says, ""oops, there goes another rubber tree plant."" People have always been in awe of ants' ability to work together to get the seemingly impossible done – but how, exactly, do they do it? Now we know, thanks to a Weizmann team that created a physics-based model showing how groups of ants cooperate to carry large pieces of food to the nest.
