Aug 15, 2019... REHOVOT, ISRAEL—August 15, 2019—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.

Dear friends and members of the Weizmann Institute of Science community,
The coronavirus outbreak is a global challenge that forces us all to significantly and rapidly adjust our way of life and change our work routines.
Just a few months ago we might have imagined such an event playing out only in books or movies. But epidemiologists, immunologists, and public health officials have long anticipated the possibility of a pandemic. The theoretical policies developed during these more peaceful days are now being implemented worldwide to address the current crisis.

A new computer algorithm developed by researchers at the Weizmann Institute of Science in Rehovot can predict which women are at a high risk of gestational diabetes in the early stages of pregnancy or even before it has occurred, the institute said in a press release Monday afternoon.
The study analyzed data on nearly 600,000 pregnancies available from Israel's largest health insurance provider, Clalit Health Services, the Weizmann Institute of Science said. According to the institute, the algorithm may help prevent gestational diabetes using nutritional and lifestyle changes.

REHOVOT, ISRAEL—September 12, 2019—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.

The lungs of a mouse with untreated Ewing sarcoma (left) contain numerous tumor cells (shown by luminescent colors) that have spread from the bone; the lungs of a mouse treated with a drug reducing the synthesis of glucocorticoids are almost free from the sarcoma (right)
REHOVOT, ISRAEL—October 2, 2019—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.

Oct 07, 2019... In the recurring, deadly Ebola outbreaks in parts of Africa, today’s health workers now have at least some tools to fight the disease: vaccines. Vaccines against Ebola have been administered to over 100,000 people to date, but they are barely out of the experimental stage. It is not known how well these vaccines will provide long-term protection across a broad population. Furthermore, on the basic scientific level, the effects of vaccination on the immune system and how the immune response of vaccinated individuals compares with that of individuals who have survived Ebola infections was not known. A Weizmann Institute of Science lab recently joined forces with a research team in Cologne, Germany, to uncover the details of the molecular response that occurs in the immune system after vaccination against Ebola. Their findings may help health organizations devise better strategies for containing and preventing the disease.

A trailblazing study by Israeli researchers suggests that intestinal microbes may have a direct effect on the course of amyotrophic lateral sclerosis (ALS), the incurable, fatal neurodegenerative disease also known as Lou Gehrig’s disease that affected physicist Stephen Hawking.
Published today in Nature, the study by researchers at the Weizmann Institute of Science revealed that the progression of an ALS-like disease in lab mice was slowed after the mice received certain strains of gut microbes or substances known to be secreted by these microbes.

Gut microbes such as these were found to have altered levels in ALS patients
REHOVOT, ISRAEL—July 22, 2019—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.

JERUSALEM — Teams of epidemiologists and computer scientists on three continents have started mass population surveys to try to get ahead of the coronavirus and ensure that scarce diagnostic tests, and even scarcer ventilators, are sent where they can do the most good.
More than two million people in Britain and 150,000 Israelis have already completed simple questionnaires, and many are updating their answers daily. Analysts of the data — including symptoms of Covid-19 and test results, as well as risk factors and demographics — say they have been able to identify incipient outbreaks days ahead of the authorities.

When immune cells (macrophage, blue) meet bacteria (red), the first day or two is critical for the eventual outcome
REHOVOT, ISRAEL—July 22, 2019—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.
