About Us
Founded in 1944, the American Committee for the Weizmann Institute of Science develops philanthropic support for the Weizmann Institute in Israel, and advances its mission of science for the future of humanity.

Just as COVID-19 is still advancing, so is the research of Weizmann Institute scientists as they develop ways to identify, predict, treat, and prevent the illness. One particularly innovative researcher is Prof. Noam Sobel.
A neurobiologist who is a world leader in olfaction research, Prof. Sobel works in the Weizmann tradition of following his curiosity as he harnesses the sense of smell to fight COVID. His previous studies have shown that our olfactory system has powers that many of us would never have imagined; he has used the sense of smell – our most ancient sense – to quantify the smell of fear; shed light on social miscues in autism and diagnose the condition; help locked-in, vegetative patients communicate; reveal subconscious reactions to the opposite sex; and much more.

A joint study by Tel Aviv University (TAU) and Weizmann Institute of Science researchers has yielded an innovative method for bolstering memory processes in the brain during sleep.
The method relies on a memory-evoking scent administered to one nostril. It helps researchers understand how sleep aids memory, and in the future could possibly help to restore memory capabilities following brain injuries or help treat people with post-traumatic stress disorder (PTSD) for whom memory often serves as a trigger.

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.”
Aug 13, 2020... Prof. Eran Hornstein, a member of the steering committee for Weizmann’s new Institute for Brain and Neural Sciences, discusses this important flagship project, which will bring together experts in multiple disciplines to understand mental illness, advance treatments for diseases like Alzheimer's and Parkinson's, and much more. He explains why Weizmann is in an ideal position to uncover the brain's mysteries, with more than 40 internationally renowned research groups dedicated to addressing the most pressing topics in neuroscience.
May 27, 2020... Olfaction expert Prof. Noam Sobel takes us through his attempts to “train” an electronic nose to identify Covid. This may be possible because “every disease has an odor,” he says. “Diseases change metabolic processes, and metabolites have a smell.”
Sep 29, 2020... REHOVOT, ISRAEL—September 29, 2020—The odors we give off are a sort of body language – one that may affect our relationships more than we realize. New research from the lab of Prof. Noam Sobel at the Weizmann Institute of Science suggests that this “chemical communication” may extend to human reproduction as well. The study, which was published in eLife, found that women who suffer from a condition known as unexplained repeated pregnancy loss (uRPL) process messages concerning male body odor – especially their husband’s – in a different way than other women. These findings may point to new directions in the search for causes and prevention of this poorly understood disorder.
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.

Nov 11, 2020... REHOVOT, ISRAEL—November 11, 2020—Fragrances – promising mystery and intrigue – are blended by master perfumers, their recipes kept secret. In a new study on the sense of smell, Weizmann Institute of Science researchers have managed to strip much of the mystery from even complex blends of odorants, not by uncovering their secret ingredients, but by recording and mapping how they are perceived. The scientists can now predict how any complex odorant will smell from its molecular structure alone. This study may not only revolutionize the world of perfumery, but eventually lead to the ability to digitize and reproduce smells on command. A proposed framework for odors, created by neurobiologists, computer scientists, and a master perfumer and funded by a European Commission initiative called Future and Emerging Technologies (FET) Open, was published in Nature.

We have all experienced a warped sense of time during these Groundhog Blursdays of the pandemic – but why?
Some reasons are obvious. We have lost our guideposts, and events that occurred like clockwork – holidays, birthdays – have largely been cancelled. Seasons and school days aren’t well-defined. Weekends – what’s the diff?
And if you are fortunate enough to work remotely, you no longer have the adjustment period of a commute; going straight from bed to the kitchen coffeemaker to one’s makeshift office is simply not the same. Our environment, clothing, and habits are unchanging.
Jan 07, 2021... REHOVOT, ISRAEL—January 7, 2021—Some people lose their eyesight, yet continue to “see.” This phenomenon, a kind of vivid visual hallucination, is named after Swiss doctor Charles Bonnet, who described in 1769 how his completely blind grandfather experienced intense, detailed visions of people, animals, and objects. Charles Bonnet syndrome was investigated in a study led by scientists at the Weizmann Institute of Science. The findings, published in Brain, suggest a mechanism by which normal, spontaneous activity in the visual centers of the brain can trigger visual hallucinations in the blind.
