    February is American Heart Month

    Our hearts mean many things: love, strength, loyalty. But even if we look at hearts from a purely biological perspective, they are still awesome – and complicated, particularly when it comes to disease. That's why, for American Heart Month, we'd like to share some of the many approaches Weizmann Institute scientists are taking to fight heart disease.

    What the Weizmann Institute is Doing About Heart Disease

    According to the American Heart Association, more than 80 million Americans have one or more forms of cardiovascular disease. Weizmann researchers are not only searching for solutions to this health epidemic, but are also investigating the very earliest causes, such as problems during embryonic formation.

    Tumors Might Grow Faster at Night

    Work, school, errands, commutes … it makes sense that we are more stressed during the day than when we're sleeping. And we do, in fact, produce more glucocorticoid (GC) – aka the stress hormone – during our waking hours. Now Weizmann scientists have found that GC also helps suppress cancer growth, meaning that perhaps we should be administering cancer drugs at night, while our bodies aren't fighting the cancer themselves.

    Stem Cells, Changing Fast

    Stem cell research is one of the fastest-moving fields of science today, with new findings coming one after another. In just the past several months alone, Weizmann scientists have discovered important new information about how stem cells grow, choose their fates, and can be reprogrammed. These mighty cells have the potential to change medicine as we know it.

    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.

    Building a Better Antibiotic

    The research of Prof. Ada Yonath, winner of the 2009 Nobel Prize in Chemistry, is revolutionizing the world of antibiotics. Different and better antibiotics are needed to fight an emerging health crisis: antibiotic-resistant ""superbugs.""
