What is the origin of life? It’s one of humanity’s greatest questions, and theories differ amidst the scientific community. Right now, the leading hypothesis is that life developed from RNA molecules, known for being able to self-replicate.
Weizmann’s Prof. Doron Lancet disagrees, and thinks it’s highly improbable that the origin of life traces back to a single complex molecule. More likely, he believes it traces back to assemblies of simple chemical compounds that can form spontaneously and reproduce as a whole, and he’s built a computational chemistry model to show the feasibility of this alternative timeline.
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.

Feb 15, 2022... In the end, it’s all about making a connection. In their recent study, Prof. Maya Schuldiner and her team from the Weizmann Institute of Science’s Molecular Genetics Department uncover for the first time how the cell’s Most Valuable Players – the nucleus and mitochondria – communicate through the formation of dedicated contact sites. Being able to tune in on these correspondences will allow scientists to better understand conditions where they are disrupted from cancer to neurodegenerative diseases. These findings join a series of recent discoveries in the budding field of contact site biology, some of which were made in Schuldiner’s lab.

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.
