In Women's Tears, a Chemical That Says, ‘Not Tonight, Dear'
In Women's Tears, a Chemical That Says, ‘Not Tonight, Dear'

https://www.weizmann-usa.org/news-media/in-the-news/in-women-s-tears-a-chemical-that-says-not-tonight-dear/

Jan 06, 2011... When we cry, we may be doing more than expressing emotion. Our tears, according to striking new research, may be sending chemical signals that influence the behavior of other people.
The research, published on Thursday in the journal Science, could begin to explain something that has baffled scientists for generations: Why do humans, unlike seemingly any other species, cry emotional tears?
In several experiments, researchers found that men who sniffed drops of women’s emotional tears became less sexually aroused than when they sniffed a neutral saline solution that had been dribbled down women’s cheeks. While the studies were not large, the findings showed up in a variety of ways, including testosterone levels, skin responses, brain imaging and the men’s descriptions of their arousal.

May 08, 2019... Meet visual neuroscientist Dr. Michal Rivlin, the 2019 Life Sciences Laureate of the Blavatnik Awards for Young Scientists. Dr. Rivlin’s research is making major strides in understanding sight, in particular the retina, the part of the eye where all visual processes begin. She has found that retinal cells, rather than being fixed and hardwired, are malleable and can dramatically change their properties in response to stimuli like light and motion. Her work has implications for retinal disease and blindness, and the development of computer vision technologies. The Blavatnik Awards, presented by The Blavatnik Family Foundation, the New York Academy of Sciences, and the Israel Academy of Sciences and Humanities (IASH), recognize early-career scientists and engineers in Israel for both their extraordinary achievements and promise for future discoveries. Of the three 2019 laureates, two were from the Weizmann Institute; the other Weizmann winner was Prof. Erez Berg of the Department of Condensed Matter Physics.

A Sniff Test for Coronavirus?
A Sniff Test for Coronavirus?

https://www.weizmann-usa.org/news-media/feature-stories/a-sniff-test-for-coronavirus/

May 04, 2020... Prof. Noam Sobel, of the Department of Neurobiology, is a leading authority on how olfaction affects human behavior and health. Data emerging from the coronavirus pandemic show that many patients experience a temporary loss of their sense of smell. So dramatic is this loss that, in some countries, patients who report a sudden loss of olfactory acuity are declared to be coronavirus patients, even without further testing. The CDC recently added olfactory loss as a formal symptom of COVID-19.

Self-Monitoring Your Sense of Smell May Help Detect Coronavirus

Apr 02, 2020... REHOVOT, ISRAEL—April 2, 2020—Along with fever, cough, and shortness of breath, many COVID-19 patients report a temporary loss of sense of smell. It appears that olfactory loss is significantly greater in coronavirus patients compared to the loss often experienced during a cold and, less commonly, in influenza (non-COVID-19) patients. In some countries, such as France, a patient who claims to have sudden onset of olfactory loss will be diagnosed as a coronavirus patient – without even being tested. A similar approach is being considered in the U.K. Based on this data, Weizmann Institute of Science investigators, in collaboration with Israel’s Edith Wolfson Medical Center, developed SmellTracker – an online platform that enables self-monitoring of one’s sense of smell – in order to detect early signs of COVID-19, or in the absence of other symptoms.

Apr 05, 2020... Is your sense of smell suddenly not working very well? Not to panic you, but sudden olfactory loss has emerged as a significant symptom in about 60 percent of COVID-19 patients.
In fact, in France, people reporting a dramatic drop-off in their ability to smell are automatically assumed coronavirus-positive.
Based on this data, Weizmann Institute scientists, in collaboration with Wolfson Medical Center in Holon, developed SmellTracker – an online platform that enables self-monitoring of smell in order to detect early signs of COVID-19.

You Can’t Stop Touching Your Face Because You’re Programed To Sniff Your Hand, Scientists Say
You Can’t Stop Touching Your Face Because You’re Programed To Sniff Your Hand, Scientists Say

https://www.weizmann-usa.org/news-media/in-the-news/you-can-t-stop-touching-your-face-because-you-re-programed-to-sniff-your-hand-scientists-say/

Apr 20, 2020... Humans touch their own faces often because they are subconsciously smelling themselves for a variety of reasons, scientists believe. The team also conducted a survey to see whether people subconsciously smell themselves and others, and found more than half of the participants had smelled a stranger.
The authors of the article titled Are humans constantly but subconsciously smelling themselves? published in the journal Royal Society journal Philosophical Transactions B reviewed existing studies to understand if and why humans smell themselves.

May 11, 2020... If you’re getting bored in quarantine, here’s a fun new hobby to try: sniffing stuff in your kitchen. Two international projects are asking ordinary people to rate the scents of household items in order to gather data on one of COVID-19’s more mysterious symptoms: anosmia, the loss of the ability to smell.
It’s still unclear to scientists how widespread anosmia is among COVID-19 patients, which typically causes a fever, dry cough and difficulty breathing. And whether it can be a useful way to track the spread of the disease is still to be determined — leaving researchers eager to gather as much data on the symptom as possible.

Apr 27, 2020... COVID-19 has separated us from the world in surprising ways. Yes, we all miss our friends and loved ones, and we miss going to restaurants and stores and movies and concerts. But there’s another pastime that COVID-19 has deprived us of, even if we don’t realize it: the simple pleasure of subconsciously touching our own faces and sniffing our hands.
As COVID-19 spread, the Centers for Disease Control and Prevention warned people against touching their faces — and for good reason: A 2006 study suggested that nearly 25 percent of respiratory disease transfer could be attributed to people touching their faces.

A “Sniff Test” Signals Consciousness After a Brain Injury, Study Shows
A “Sniff Test” Signals Consciousness After a Brain Injury, Study Shows

https://www.weizmann-usa.org/news-media/in-the-news/a-sniff-test-signals-consciousness-after-a-brain-injury-study-shows/

Apr 29, 2020... An unconscious person’s response to odors after a serious brain injury may be a simple yet powerful signal of how aware they are and how likely they are to survive and recover, a new study suggests, relying on responses to the scent of shampoo and the stench of rotting fish.
Patients who survive brain damage from trauma, stroke, or heart attack are plunged into forms of unconsciousness that vary from minimal consciousness to unresponsive wakefulness, sometimes called a vegetative state. Specialists trying to tell who is in which state have fared only a little better than a coin flip: About 4 in 10 people thought to be unconscious are actually aware.

Apr 30, 2020... REHOVOT, ISRAEL—April 30, 2020—If an unconscious person responds to smell through a slight change in their nasal airflow pattern, they are likely to regain consciousness. This is the conclusion from a new study conducted by Weizmann Institute scientists and colleagues at Israel’s Loewenstein Rehabilitation Hospital. According to the findings, published in the journal Nature, 100% of the unconscious brain-injured patients who responded to a “sniff test” developed by the researchers regained consciousness during the four-year study period.
