    Science Tips, July 2013

    Three updates from the Weizmann Institute: teaching nanowires to assemble themselves, which could improve devices such as lasers and solar cells; outlining the 10-stage pathway that turns cholesterol into a dangerous toxin in potatoes; identifying the traffic-pattern-like nature of gene transcription could lead to a new generation of drugs.

    Science Tips, July 2012

    Three updates from the Weizmann Institute: fool's gold regulates environmental oxygen; finding a molecular mechanism behind faulty stem cells and cancer; and solving the mystery of where importins – proteins critical to healing nerve damage – are produced.

  • 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.

    Time is of the Essence

    Many of our biological processes follow a 24-hour ""body clock."" Triglyceride (TAG) levels do as well. Strangely, when no biological clock is present, TAG levels in mice still fluctuate. Dr. Gad Asher and colleagues changed when the mice ate – and cut their TAG levels in half. Could merely changing meal time treat TAG-related diseases?

  • Science Tips, March 2013

    Three updates from the Weizmann Institute: scientists take steps toward building a complete, functional, artificial cell; progress is made toward understanding the measurement process in quantum systems; and a new study may help develop ways to control tissue destruction that results from inflammation and necrosis.

  • Science Tips, February 2013

    Three updates from the Weizmann Institute: a pre-explosion signals that a star is about to go supernova; a two-antibody approach for attacking triple-negative breast cancer; and a genetic device, operating independently in bacteria, performs DNA diagnosis.

    Lineage Trees Reveal Cells' Histories

    Using a method he developed for determining the ""family trees"" of cells, Prof. Ehud Shapiro and a cross-disciplinary team of Weizmann scientists, including Prof. Nava Dekel, was able to prove—and disprove—some ideas about the female mammal's egg supply.
