Raphael Mechoulam’s research has driven the current medical marijuana boom – and is helping people suffering from a host of conditions.
Following the wave of marijuana legalization across America, THC and CBD products are now everywhere: gummy bears, energy drinks, chocolate, even skincare products. Before laws were changed, scientists in the U.S. were handicapped in their ability to research marijuana, thus giving a decades-long edge to scientists elsewhere. Scientists like Prof. Raphael Mechoulam at Israel’s Weizmann Institute. As a young academic, Mechoulam was able to convince the police to give him hashish for his research (one of his many fascinating stories.) This led to a relationship that continued for over 40 years.

A non-toxic blue dye commonly used in biology labs helps repair damaged heart tissue in mice, say researchers at the Weizmann Institute of Science in Israel.
As described in the Journal of Clinical Investigation Insight, a dye molecule called Chicago Sky Blue reduced scar size and improved heart function of adult mice following induced myocardial infarction (heart attack).
Once damaged, heart muscle cells (cardiomyocytes) can never regenerate. But when research student Oren Yifa and his team injected Chicago Sky Blue into the post-heart attack mice in the molecular cell biology lab of Prof. Eldad Tzahor, the mice’s heart function improved.

Apr 20, 2020... REHOVOT, ISRAEL—April 20, 2020—As the cell’s protein factory, the ribosome is the only natural machine that manufactures its own parts. That’s why understanding how the machine itself is made could unlock the door to everything from understanding how life develops to designing new methods of drug production. An intensive research effort at the Weizmann Institute of Science has now demonstrated the self-synthesis and assembly of the small subunit of a ribosome – 30S – on a surface of a chip. The findings were published in Science Advances.

Israeli researchers have discovered new entities created from interaction between matter and light particles, Weizmann Institute of Science (WIS) reported Wednesday.
The research, published in the journal Nature Communications, has several implications in developing quantum applications, fine control of chemical processes and designing new materials.
The difference between light and matter should be a clear and simple division, but there are situations in which the two become so closely connected that the situation becomes blurred.

Our mental health is always important, but more so than ever during these challenging times. Between the ongoing COVID pandemic, economic insecurity, social turmoil, and the like, rates of anxiety and depression are skyrocketing. How to cope? And why do we experience mental health issues in the first place?
As with the coronavirus, the answers are found in science.
The Weizmann Institute’s renowned neuroscientists do more than study the brain; they investigate how this most mysterious of organs responds to the world, processes our experiences, plays a role in emotional response, consolidates memories, becomes ill, and more. Our scientists also seek to develop effective medications and treatments. As Prof. Alon Chen – a renowned expert in neuropsychiatry and Weizmann Institute president – says, “I strongly believe that when we identify the mechanisms in the brain, we can use them to develop better ways to treat these conditions.”
Oct 05, 2020... REHOVOT, ISRAEL—October 5, 2020—Our ancestors not only knew how to use fire, they also developed sophisticated technologies for making tools. Researchers at the Weizmann Institute of Science recently employed cutting-edge technologies of their own to take a fresh look at a collection of stone tools. Their results suggest that the early humans who made the tools may have had a good understanding of the effects of heating the stone before flaking it into blades, and may even have used different temperatures to create different types of tools. The findings of this research were published in Nature Human Behaviour.

Dec 23, 2020... REHOVOT, ISRAEL—December 23, 2020—As the plastics in our oceans break up into smaller and smaller bits without breaking down chemically, the resulting microplastics are becoming a serious ecological problem. A new study by the Weizmann Institute of Science, published in Nature Communications, reveals another troubling aspect of microplastics (defined as particles smaller than 5 mm across): they are swept up into the atmosphere and carried on the wind to far-flung parts of the ocean, including those that appear to be plastic-free. Analysis reveals that such minuscule fragments can stay airborne for hours or days, spreading the potential to harm the marine environment and, by climbing up the food chain, to affect human health.

Feb 25, 2021... REHOVOT, ISRAEL—February 25, 2021—Around 2.5 billion years ago, our planet experienced what was possibly the greatest change in its history: According to the geological record, molecular oxygen suddenly went from nonexistent to becoming freely available everywhere. Evidence for what is called the Great Oxygenation Event (GOE) is clearly visible – for example, in banded iron formations containing oxidized iron. The GOE is, of course, what allowed oxygen-using organisms – including, eventually, us – to evolve. But was it indeed a “great event” in the sense that the change was radical and sudden, or were organisms that were alive at the time already using free oxygen, just at lower levels?

The worldwide community of the Weizmann Institute of Science deeply mourns the passing of our beloved longtime leader, preeminent scientist, and dear friend, Prof. Michael Sela.
Throughout his illustrious career, Michael made numerous discoveries that forever changed immunological research, shedding light on the genetic control of the immune response.
He co-invented the blockbuster drug Copaxone® for the treatment of multiple sclerosis as well as three cancer treatment drugs – Erbitux®, Vectibix®, and Portrazza® – which have improved the lives of millions worldwide.

Nov 10, 2022...
More than a century ago, in 1915, a senior lecturer in biochemistry at the University of Manchester named Dr. Chaim Weizmann invented a fermentation process that converted starch — a poly-sugar readily available from corn and potatoes — into acetone and butyl alcohol, facilitated by a bacteria, Clostridium acetobutylicum, that Dr. Weizmann had previously isolated.
This novel method of acetone production became known as “the Weizmann process.” As serendipity would have it, acetone was a key component in the production of the smokeless gunpowder (cordite) used by the Allies in World War I. Acetone had previously been made from calcium acetate imported from Germany, but since the Allies were at war with Germany, this was no longer possible, and the U.S. had a sparse supply. So, Winston Churchill, then First Lord of the Admiralty, requested that the “Weizmann process” be used to mass produce acetone in England, Canada, and the U.S.
