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.

Human beings did not invent democracy. Among certain animal species, decisions are also made in accordance with the majority opinion, with each individual having an equal degree of influence. For example, certain flocks of birds decide how and when to fly based on how the majority chooses to move.
In a frequently observed phenomenon unique to human beings, the majority will concede to the minority on a certain issue in order to avoid conflict, while compromising on its needs, convenience or views in the process. Now, for the first time, scientific research has identified a similar concession by the majority among animals. The experiment was conducted on carpenter ants (Camponotus sanctus), a Middle Eastern species commonly found in Israel in the mountainous areas around Jerusalem. The findings were published last week in the journal Current Biology.
Jun 13, 2022... REHOVOT, ISRAEL—June 13, 2022—They say that where there’s smoke, there’s fire, and Weizmann Institute of Science researchers are working hard to investigate that claim, or at least elucidate what constitutes “smoke.” In an article published today in PNAS, the scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years – one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but – perhaps more importantly – it could help us better understand the origins of the human story, our most basic traditions, and our experimental and innovative nature.
Jun 24, 2022... REHOVOT, ISRAEL—June 23, 2022—Weizmann Institute of Science researchers have found that people may have a tendency to form friendships with individuals who have a similar body odor. The researchers were even able to predict the quality of social interactions between complete strangers by first “smelling” them with a device known as an electronic nose, or eNose. These findings, published today in Science Advances, suggest that the sense of smell may play a larger role in human social interactions than previously thought.

Homo sapiens has come to dominate the planet, but what are the traits that have allowed humans to have such a position? On this episode, “Human Story,” Dr. Liat Ben David, CEO of the Davidson Institute of Science Education, the educational arm of Israel's acclaimed Weizmann Institute of Science, discusses her book, The Story of Our Lives, The: Homo Sapiens' Secrets of Success.
Excerpt from Groks Science Show"I do have strong beliefs that through the education processes such as we’re doing at Davidson with youths — from not only Israel but all over the world — creating and developing science literacy as the tools for making decisions and solving problems for more and more of our youngsters, and if we want the bright future that I’m talking about, science literacy is the pillar of building up a better, democratic, and tolerant society.” – Dr. Liat Ben David

Aug 24, 2022... REHOVOT, ISRAEL—August 24, 2022—Even during such routine tasks as a daily stroll, our brain sometimes needs to shift gears, switching from navigating the city to jumping out of the way of a bike or to crossing the street to greet a friend. These switches pose a challenge: How do the brain’s circuits deal with such dynamic and abrupt changes in behavior? A Weizmann Institute of Science study on bats, published today in Nature, suggests an answer that does not fit the classical thinking about brain function.

Researchers have for years tried to discover what determines “resilience to stress,” a term describing the ability to adapt to difficult situations and to overcome adversity. Is it acquired through experience, or is there a tendency to easily recover from stress possibly ingrained in us from a very early age or even from birth?
A new study lead by Prof. Gil Levkowitz of the molecular cell biology and molecular neuroscience departments at the Weizmann Institute of Science in Rehovot has revealed an important piece of this puzzle. The study examined zebrafish – small, black-and-white-striped, transparent fish whose natural habitat spans rivers, ponds and rice paddies in Pakistan, Myanmar, Nepal and India.
Aug 02, 2023... REHOVOT, ISRAEL—August 2, 2023—Scientific excellence requires diversity – research conducted by people from different backgrounds and with varied worldviews. The need for diversity extends to scientific experiments themselves, but the vast majority of studies in the life sciences are conducted using male mice only, which could not only bias the findings, but impede our ability to extrapolate from them to humans. A new study by researchers from the Weizmann Institute of Science addresses this challenge, revealing in unprecedented detail how the brains of male and female mice respond differently to stress.
Dec 06, 2023... REHOVOT, ISRAEL—December 6, 2023— The images of Israeli child hostages being freed from Hamas captivity are heartwarming, but for most of these children, the release is just the start of a long rehabilitation process. Countless studies have shown that exposure to warfare, abuse and other traumatic events at a young age significantly raises the risk of ill health, social problems and mental health issues later in life. Now, a new study by researchers at the Weizmann Institute of Science published in Science Advances provides a reason for optimism. In research conducted on mice, a team headed by Prof. Alon Chen discovered brain mechanisms that go awry as a result of exposure to trauma in infancy and showed that these changes may be reversible if treated early.
