REHOVOT, ISRAEL—April 20, 2020—The Israel Institute for Biological Research and the Weizmann Institute of Science will join efforts in advancing research designed to develop ways to combat the coronavirus. A Memorandum of Understanding (MoU) between the two Institutes on this matter has been signed in recent days.
The neighboring Institutes are characterized by their unique excellence in their respective fields, and collaboration between the two is likely to promote synergy and accelerate the process that scientists hope will lead to a medical solution to the coronavirus. The Institute for Biological Research’s Director General, Prof. Shmuel Shapira, and the Weizmann Institute of Science’s Vice President for Technology Transfer, Prof. Irit Sagi, say that signing the MoU is an important milestone among the broad range of joint activities established between the two Institutes.

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.
Jun 02, 2020... In this special update from his home in New York City, CEO Dave Doneson discusses the Weizmann Institute’s remarkable coronavirus response. Dave shares how the Institute has rapidly shifted its focus to address the pandemic, transforming into one of the world’s leading hubs of COVID-19 research. Weizmann scientists are fighting this disease on a variety of fronts, offering hope and optimism for us all.

REHOVOT, ISRAEL—June 15, 2020—During the pandemic lockdown, as couples have been forced to spend days and weeks in one another’s company, some have found their love renewed while others are on their way to divorce court. Oxytocin, a peptide produced in the brain, is complicated in that way: a neuromodulator, it may bring hearts together or it can help induce aggression. That conclusion arises from unique research led by Weizmann Institute of Science researchers in which mice living in semi-natural conditions had their oxytocin-producing brain cells manipulated in a highly precise manner. The findings, which were published in Neuron, could shed new light on efforts to use oxytocin to treat a variety of psychiatric conditions, from social anxiety and autism to schizophrenia.

Jun 22, 2020... REHOVOT, ISRAEL—June 22, 2020—What did the very first proteins – those that appeared on Earth around 3.7 billion years ago – look like? Prof. Dan Tawfik of the Weizmann Institute of Science and Prof. Norman Metanis of the Hebrew University of Jerusalem have reconstructed protein sequences that may well resemble those ancestors of modern proteins, and their research suggests a way that these primitive proteins could have progressed to forming living cells. Their findings were published in the Proceedings of the National Academy of Sciences (PNAS).

There is an invisible universe hidden inside your body, it’s called the gut microbiome - a vast array of trillions of intestinal bacteria, hundreds of different species. They help digest your food in exchange for a warm, safe place to live. And we are only now starting to discover the gut microbiome plays a much larger role in our lives than we ever imagined.
Some of those bacteria found inside us are replicated in commercially manufactured mixtures called “probiotics.” You see them on grocery and pharmacy shelves, and they're recommended by your friends and often, by doctors like me.
Aug 10, 2020... REHOVOT, ISRAEL—August 10, 2020—Invading cells’ private space – prying into their internal functions, decisions, and communications – could be a powerful tool that may help researchers develop new immunotherapy treatments for cancer. As reported in Cell, a research group at the Weizmann Institute of Science have developed a technology enabling them to see inside tens of thousands of individual cells, at once, in greater detail than ever before.
Sep 24, 2020... Our sense of time may be the scaffolding for all of our experience and behavior, but it is an unsteady and subjective one, expanding and contracting like an accordion. Emotions, music, events in our surroundings and shifts in our attention all have the power to speed time up for us or slow it down. When presented with images on a screen, we perceive angry faces as lasting longer than neutral ones, spiders as lasting longer than butterflies, and the color red as lasting longer than blue. The watched pot never boils, and time flies when we’re having fun.

Most marathoners follow up long training runs with an ice bath and a nap. Gamini Sugathadasa, a bellman at the Four Seasons Hotel Las Vegas, runs 20 miles and then spends eight more hours on his feet. According to his fitness tracker, he averages 14,000 steps during a typical shift.
When the hotel closed in mid-March due to the coronavirus, he made up for the steps by pounding out more miles on his treadmill. The concept of a marathon was foreign to Mr. Sugathadasa until 2009, when he was greeting guests who had finished the Rock ‘n’ Roll Las Vegas Marathon. “I just remember everyone looked so happy,” he says. Intrigued, he left work that day and ran 11 miles. Despite some stiffness, he went out and ran the same distance the following three days. He was a natural.
Apr 14, 2021... REHOVOT, ISRAEL—April 14, 2021—Being constantly hungry, no matter how much you eat – that’s the daily struggle of people with genetic defects in the brain’s appetite controls, and it often ends in severe obesity. In a study published in Science, researchers at the Weizmann Institute of Science, together with colleagues from the Queen Mary University of London and the Hebrew University of Jerusalem, have revealed the mechanism of action of the master switch for hunger in the brain: a receptor called melanocortin 4 (MC4). They have also clarified how this switch is activated by setmelanotide (brand name Imcivree), a drug recently approved for the treatment of severe obesity caused by certain genetic changes. The team’s findings shed new light on the way hunger is regulated and may help develop improved anti-obesity medications.
