Jan 24, 2020... “According to Gallup, in 2018, more Americans were stressed, worried and angry than at any point in the last 12 years. That is extraordinary when you consider that the past dozen years includes the 2008 financial crisis and multiple terrorist attacks. Furthermore, American stress levels are among the highest in the world. Seriously, Americans were as stressed as Iranians and more stressed than citizens of Rwanda, Turkey, and Venezuela,” reports The Washington Post, adding the technically accurate diagnosis: “That’s nuts.”

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.
Sep 27, 2019... Fall is here and school is back in session. In the ninth episode of Weizmann in Focus, CEO Dave Doneson shares a simple tip to help prepare for success this academic year. Weizmann Prof. Noam Sobel, who studies the olfactory system, found that people who inhaled when presented with a problem-solving task performed better than those who exhaled. So, the next time you’re faced with a difficult task, take a deep breath!

JERUSALEM, July 29 (Xinhua) – Israeli scientists discovered how oxytocin, known as the “love hormone,” is restocked in the brain, the Weizmann Institute of Science (WIS) said Monday.
Oxytocin is responsible, for example, for a burst of happiness with parents gazing at their newborn baby or a loving couple exchanging glances.
However, oxytocin is not only a hormone of love but also plays a role in normal social interaction, birth and breastfeeding, control of stress and appetite and more.

Seconds before a memory pops up, certain nerve cells jolt into action in sync. This new finding sheds light on how the brain stores and recalls information.
Studying brain cells in action inside the human head is tricky. Putting electrodes in someone’s brain requires surgery. It’s not something researchers do without a good reason. The new study involved people who already had electrodes put in their brains for some medical purpose. These participants all had epilepsy. That brain disorder causes storm-like surges of electrical activity in the brain, known as seizures. Doctors put the electrodes in the patients' brains so they could pinpoint those surges.

Computer-enhanced MRI images of the brains of left-handed women identified two that were missing olfactory bulbs
REHOVOT, ISRAEL—November 6, 2019—Is a pair of brain structures called the olfactory bulbs, which are said to encode our sense of smell, necessary? That is, are they essential to the existence of this sense? Weizmann Institute of Science researchers recently showed that some humans can smell just fine, thank you, without said bulbs. Their finding – that around 0.6% of women, and more specifically, up to 4% of left-handed women, have completely intact senses of smell despite having no olfactory bulbs in their brains – calls into question the accepted notion that this structure is absolutely necessary for the act of smelling. The findings of this research, which were published in Neuron, could shake up certain conventional theories that describe the workings of our sense of smell.

If you’re ever unfortunate enough to require brain surgery, Israeli startup Nurami Medical has got you covered – literally.
The Haifa-based company has developed a patch made of synthetic, biodegradable nanofibers meant to be affixed to the dura mater – the protective membrane underneath the skull that keeps the brain and spinal cord safe – after cranial neurosurgery.

JERUSALEM, Sept. 23 (Xinhua) – Israeli and U.S. researchers found that glioblastoma brain cancer cells come in four states and can transition from one state to another, the Weizmann Institute of Science (WIS) in central Israel reported on Monday.
The study, published in the journal Cell, was led by researchers from WIS, Massachusetts General Hospital (MGH) in Boston and the Salk Institute for Biological Studies in La Jolla, California.
Feb 24, 2020... Think about the last time you had a cold. Think how weird it felt to not be able to smell or taste anything just because your nose was clogged up. That is, to an extent, the life of people with anosmia: the term for not being able to smell. Some patients are born with it. For others, it is the result of a neurological diseases, and for others still, it comes from a surgery that removed or damaged the olfactory bulb (OB). For a long time, it was believed that without an OB, a person would not be able to smell, but a team of researchers in Israel found patients who might prove that notion wrong.

Pairs of face images that elicited similar (left column) and different (right column) neuronal activation patterns. Each bar shows the response of one electrode to the face in the photo; the higher the bar and the lighter the red, the stronger the response
REHOVOT, ISRAEL—October 30, 2019—Our brains are so primed to recognize faces – or to tell people apart – that we rarely even stop to think about it, but what happens in the brain when it engages in such recognition is still far from understood. In a new study published in Nature Communications, researchers at the Weizmann Institute of Science have shed new light on this issue. They found a striking similarity between the way in which faces are encoded in the brain and successfully performing artificial intelligence (AI) systems known as deep neural networks.
