The 11th President of the Weizmann Institute of Science and Four New Vice Presidents Take Office
The 11th president of the Weizmann Institute of Science, Prof. Alon Chen, took office on December 1, joined by four new vice presidents. “The Weizmann Institute is a world-leading research institution that generates transformative knowledge and educates the scientists of tomorrow,” said Prof. Chen in his recent speech before the International Board at its annual meeting. “Our alumni embark on careers in high-tech and biotech and in academia, providing the foundations of Israel’s booming economy, just as Chaim Weizmann envisioned. As we reach the milestone of 70 years since the establishment of the Weizmann Institute, I believe it’s safe to say that we have indeed lived up to Chaim Weizmann’s expectations. Perhaps we have even exceeded them.” The full text of Prof. Alon’s speech can be found here. =

The Greenest Diet: Bacteria Switch to Eating Carbon Dioxide
Bacteria in the lab of Prof. Ron Milo of the Weizmann Institute of Science have not just sworn off sugar – they have stopped eating all of their normal solid food, existing instead on carbon dioxide (CO2) from their environment. That is, they were able to build all of their biomass from air. This feat, which involved nearly a decade of rational design, genetic engineering, and a sped-up version of evolution in the lab, was reported in Cell. The findings point to means of developing, in the future, carbon-neutral fuels.

An Exception to the Rule: An Intact Sense of Smell Without a Crucial Olfactory Brain Structure
Is a pair of brain structures called the olfactory bulbs, which are said to encode our sense of smell, necessary? That is, are they essential to the existence of this sense? Weizmann Institute of Science researchers recently showed that some humans can smell just fine, thank you, without said bulbs. Their finding – that around 0.6% of women, and more specifically, up to 4% of left-handed women, have completely intact senses of smell despite having no olfactory bulbs in their brains – calls into question the accepted notion that this structure is absolutely necessary for the act of smelling. The findings of this research, which were published in Neuron, could shake up certain conventional theories that describe the workings of our sense of smell.

For the First Time: A Method for Measuring Animal Personality
We might refer to someone’s personality as “mousy,” but in truth, mice have a range of personalities nearly as great as our own. Prof. Alon Chen and members of two groups he heads – one in the Weizmann Institute of Science’s Department of Neurobiology and one in the Max Planck Institute of Psychiatry in Munich, Germany – decided to explore personality specifically in mice. This would enable the scientists to develop a set of objective measurements for this highly slippery concept. A quantitative understanding of the traits that make each animal an individual might help answer some of the open questions in science concerning the connections between genes and behavior. The findings of this research were published in Nature Neuroscience.

Converging Solutions: Artificial Networks Shed Light on Human Face Recognition
Our brains are so primed to recognize faces – or to tell people apart – that we rarely even stop to think about it, but what happens in the brain when it engages in such recognition is still far from understood. In a new study published in Nature Communications, researchers at the Weizmann Institute of Science have shed new light on this issue. They found a striking similarity between the way in which faces are encoded in the brain and successfully performing artificial intelligence (AI) systems known as deep neural networks.

Ebola Antibodies at Work
The glycoprotein spike complex of the Ebola virus bound by a neutralizing antibody isolated from a vaccinated individual. Surface representations in grey and pink show the two distinct submits that make the trimeric Ebola spike complex. The heavy and light chains of the neutralizing antibody are shown as blue and green ribbons, respectively. The antibody neutralizes this complex by stapling two adjacent subunits and preventing conformational changes needed by the virus to enter the host cell

A New Route to Blocking Children’s Bone Cancer
Ewing sarcoma is a bone cancer that appears mainly in teenagers. Caused by a single defective gene, once it spreads to distant organs it is hard to treat. Researchers at the Weizmann Institute of Science have now discovered molecular interactions underlying Ewing sarcomas and proposed a potential treatment that has shown promise in a study in mice. These findings were published in Cell Reports.

Cancer Protocols: A New Approach to Predicting Treatment Outcomes
Diversity – at least among cancer cells – is not a good thing. Now, research from the Weizmann Institute of Science shows that in melanoma, tumors with cells that have differentiated into more diverse subtypes are less likely to be affected by the immune system, thus reducing the chance that immunotherapy will be effective. The findings of this research, which were published in Cell, may provide better tools for designing personalized protocols for cancer patients, as well as pointing toward new avenues of research into anti-cancer vaccines.

Firework Memories
Extraterrestrial scientists landing in a football stadium would be struck by the sight of the crowd suddenly standing up and shouting in unison. In a similar manner, since the 1990s, researchers have observed a special pattern of neuronal activity in rodents: tens of thousands of nerve cells firing in unison in a part of the brain called the hippocampus. But, like alien scientists, the researchers have not been able to understand the “language” of the rodents’ minds when these mysterious synchronous bursts occurred. Recently, however, Weizmann Institute of Science researchers succeeded in recording these rapid bursts of activity – called “hippocampal ripples” – in the human brain, and were able to demonstrate their importance as a neuronal mechanism underlying the engraving of new memories and their subsequent recall. These findings appeared in Science.

Next-Gen Israeli Satellite to Seek Out Cosmic Explosions and Black Holes
Weighing in at just about 160 kg (around 353 lbs), a new type of scientific satellite is planned to be built in Israel over the next four years, with a projected launch date of 2023. The satellite, known as ULTRASAT, will carry a telescope designed to observe the universe as it has never been seen before. The satellite will operate in a range of light that is normally invisible to us – ultraviolet, or UV – and have a very large field of view.

Gut Microbes May Affect the Course of ALS
Researchers at the Weizmann Institute of Science have shown in mice that intestinal microbes, collectively termed the gut microbiome, may affect the course of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. As reported in Nature, progression of an ALS-like disease was slowed after the mice received certain strains of gut microbes or substances known to be secreted by these microbes. Preliminary results suggest that the findings on the regulatory function of the microbiome may be applicable to human patients with ALS.

First Impressions Go a Long Way in the Immune System
First impressions are important – they can set the stage for the entire course of a relationship. The same is true for the impressions the cells of our immune system form when they first meet a new bacterium. Using this insight, Weizmann Institute of Science researchers have developed an algorithm that may predict the onset of diseases such as tuberculosis. The findings of this research were published in Nature Communications.

Weizmann Institute of Science Ranked in Top 25
REHOVOT, ISRAEL—June 4, 2019— The Weizmann Institute of Science has been ranked among the top 25 research institutes/universities in the world in two main categories by U-Multirank, 2019. This organization named the Institute a Global Top 25 performer in two areas: Top-Cited Publications and Patents Awarded.
This ranking, an initiative of the European Commission since 2014, uses all the information available about hundreds of institutes worldwide and analyses it according to numerous variables to show which leads in five main categories. Each category is assessed independently, according to parameters unique to that category, and they are weighted so as to add a qualitative – rather than just quantitative – dimension to the ranking. The ranking is intended to promote transparency and to aid students in applying to universities for studies and research. -
