    Science Tips, August 2014

    Three updates from the labs of the Weizmann Institute: a new technique identifies the exact DNA sequences involved in regulating the fate of blood stem cells; theorizing that tiny black holes ate their way to becoming massive quasars; nanocubes can self-assemble into beautiful, complex structures.

  • Why Chemotherapy Fails

    Prof. Ehud Shapiro leads research that shows how leukemia can evade chemotherapy. Using his method of mapping the family trees of cells, the team found that slowly dividing cancer cells are most likely to survive the toxic therapy. This could lead to new ways of fighting cancer.

  • Science Tips, May 2009

    Three research updates from the Weizmann Institute: vital steps in DNA repair; secrets of sea urchins' sharp teeth; and how white blood cells resemble millipedes.

    Science Tips, October 2012

    Three updates from the Weizmann Institute: how bacteria that live with arsenate are able to identify it; previously unknown stem-cell ""bodyguards"" in the bone marrow; and a finely tuned immune system ensures response to common ills.

    Leukemia Cells are Addicted to a Healthy Gene

    Leukemia cells are able to stay alive, aggressively dividing, virtually forever… but how? New Weizmann research suggests that about 25 percent of the time, there is a ""balance of terror"" between the cancer-promoting gene and a second, normal version. This normal gene functions alongside the mutation, keeping the cells both cancerous and alive.

    How Immune Cells Squeeze Through Blood Vessel Walls

    <em>Cosmos</em> reports on new research from Prof. Ronen Alon's lab that reveals how immune cells enter - and leave - the bloodstream. It has long been known that they can do this, but not how. The findings are particularly relevant to cancer research, as tumor cells are less able to infiltrate the bloodstream.

    Blood Test for Alzheimer's

    Twenty years of research by the Institute's Prof. Michal Schwartz has resulted in a blood test for Alzheimer's disease that is now the focus of a startup venture with U.S. collaborators. As Israel21c reports, the first human trials by the new company, NeuroQuest, show that the test is 87% accurate for Alzheimer's and ALS.

    Scientists Identify the Signature of an Aging Brain

    There is much about our brains that we still do not know, including how it is impacted by aging. But now, as <em>The Jerusalem Post</em> reports, the Weizmann Institute's Prof. Michal Schwartz and Dr. Ido Amit have ""found evidence of a unique ‘signature' that may be the ‘missing link' between cognitive decline and aging."" This discovery could someday lead to treatments to slow or reverse the process.
