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.

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.

Apr 30, 2023... REHOVOT, ISRAEL—May 1, 2023—A South African plant called a woolly umbrella is completely unrelated to the cannabis plant, yet it makes a slew of the active compounds found in cannabis – cannabinoids – including some that may have new medical uses. In a study published today in Nature Plants, Weizmann Institute of Science researchers identified more than 40 cannabinoids in the woolly umbrella, and they revealed the series of biochemical steps the plant takes when it makes these compounds. The researchers also showed how these steps can be reproduced in the lab to synthesize or even engineer new cannabinoids.
