May 31, 2022... REHOVOT, ISRAEL—May 31, 2022—Ketamine, a well-known anesthetic used in smaller doses as a party drug, was hailed as a “new hope for depression” in a Time magazine cover story in 2017. Two years later, the arrival of the first ketamine-based antidepressant – the nasal spray esketamine, made by Johnson & Johnson – was applauded as the most exciting development in the treatment of mood disorders in decades. Yet the U.S. Food and Drug Administration still limits the spray’s use. It is mainly given to depressed patients who have not been helped by other therapies – in part, because the new drug’s mechanism of action is insufficiently understood, leading to concerns over its safety.
Jun 27, 2022... REHOVOT, ISRAEL—June 27, 2022— Of all the fungi that live in the human body, the most infamous is probably the yeast Candida. This distant cousin of baker’s yeast is notorious for causing various types of thrush that can be a major nuisance, but it can also lead to an invasive infection that may, on occasion, prove fatal. In a study published today in Nature Immunology, a Weizmann Institute of Science research team headed by Prof. Jakub Abramson uncovered a previously unknown defense mechanism employed by the immune system in fighting Candida infections.
Aug 01, 2022... REHOVOT, ISRAEL—August 1, 2022— An egg meets a sperm – that’s a necessary first step in life’s beginnings, and it’s also a common first step in embryonic development research. But in a Weizmann Institute of Science study published today in Cell, researchers have grown synthetic embryo models of mice outside the womb by starting solely with stem cells cultured in a petri dish – that is, without the use of fertilized eggs. The method opens new horizons for studying how stem cells form various organs in the developing embryo, and may one day make it possible to grow tissues and organs for transplantation using synthetic embryo models.
Sep 08, 2022... REHOVOT, ISRAEL—September 8, 2022—Blood tests – simple, noninvasive and economically feasible – promise to become the next major milestone in cancer diagnosis. However, most of these tests, dubbed liquid biopsies, are currently not reliable enough for widespread use. A new, multiparameter approach developed at the Weizmann Institute of Science may lead to a blood test that will diagnose cancer with unprecedented accuracy. This research is being published today in Nature Biotechnology.

Nov 13, 2022... Bacteria have been shown to affect cancer growth, metastasis, and response therapy, but now, according to a recently published study by Weizmann scientists, fungal activity is “a new and emerging hallmark of cancer,” says Prof. Ravid Straussman of the Weizmann’s Molecular Cell Biology Department and co-leader of a recent study by researchers at the Weizmann Institute and UC-San Diego. This discovery will likely lead to better outcomes in human survival of many different cancers.

Researchers have for years tried to discover what determines “resilience to stress,” a term describing the ability to adapt to difficult situations and to overcome adversity. Is it acquired through experience, or is there a tendency to easily recover from stress possibly ingrained in us from a very early age or even from birth?
A new study lead by Prof. Gil Levkowitz of the molecular cell biology and molecular neuroscience departments at the Weizmann Institute of Science in Rehovot has revealed an important piece of this puzzle. The study examined zebrafish – small, black-and-white-striped, transparent fish whose natural habitat spans rivers, ponds and rice paddies in Pakistan, Myanmar, Nepal and India.
