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.
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.

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.

Israeli scientists say they have made a breakthrough that could pave the way for smellovision TVs, scented digital photos that have a whiff of vacation, and technology that can “print” any odor.
A Weizmann Institute team claims to have created a “smell map” that can determine how any odor will smell to humans based just on an examination of its molecular structure.
The researchers say this provides the theoretical framework to record the qualities of the smell as a set of numbers which can be used to recreate it by means of an electronic device that could be embedded in cellphones, computers, and elsewhere. They believe that a range of just 200 molecules is enough to recreate almost any smell on earth.

Dec 08, 2020... To be an expectant mother, or the anxious partner of one, is to be keenly, even agonizingly aware of how chemicals affect a developing life. The basic advice is well known, and obsessively followed: Alcohol in strict moderation, and no nicotine at all. Don’t mess with mercury. Folic acid is your friend. More protein and less caffeine. Stay away from BPA, PBCs and PFA, and generally make an enemy of the unpronounceable.

Stripping down fragrances to their molecular structure, researchers at Israel’s Weizmann Institute of Science have opened the door to a future where any scent could be digitized and reproduced on demand by a computer.
The group of neurobiologists, computer scientists and a master-perfumer wrote about their achievement in Nature.
Enabling computers to digitize and reproduce smells is a long-held goal of the study’s co-author, Prof. David Harel of the Weizmann’s computer and applied mathematics department.
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.

Scientists at the Weizmann Institute of Science have found what they say might be the cause of "Charles Bonnet syndrome," a phenomenon in which blind people continue to "see" due to vivid visual hallucinations. The research also indicated that the same visual system that humans use to see is active when humans hallucinate or even imagine.
The findings, published in the journal Brain, show a mechanism which may enable normal activity in the brain's vision centers to trigger the hallucinations in the blind. Researchers revealed a connection between resting-state brain fluctuations - mysterious but common brain occurrences which happen when humans are not conscious - and visual hallucinations in the blind.
Jan 28, 2021... Danielle Reed stopped counting after the 156th email arrived in a single afternoon. It was late March, and her laboratory at the Monell Chemical Senses Center in Philadelphia had abruptly gone into Covid-19 lockdown. For weeks, there had been little to do. Reed, who is famous in her field for helping to discover a new family of receptors that perceive bitter flavors, had spent years studying the way human genetics affect the way we experience smell and taste. It was important but niche science that seemingly had little to do with a dangerous respiratory virus spreading around the globe.
