A New Way to Measure Creativity
A New Way to Measure Creativity

https://www.weizmann-usa.org/news-media/in-the-news/a-new-way-to-measure-creativity/

Apr 07, 2022... Creativity is crucial—at the heart of human endeavors ranging from art to entrepreneurship. It’s also notoriously hard to study. Usually in psychological tests we see whether people produce a particular predetermined response to a particular question. The essence of creativity, however, is to spontaneously make something new, something no one could predict beforehand. The few measures of creativity we have are more than 50 years old, and they are hard to score and often unreliable.

Settled at Birth: Blood Vessels Remember Their Origins
Settled at Birth: Blood Vessels Remember Their Origins

https://www.weizmann-usa.org/news-media/news-releases/settled-at-birth-blood-vessels-remember-their-origins/

May 25, 2022... REHOVOT, ISRAEL – May 25 2022 – Our family origins tend to shape our future in many ways. A Weizmann Institute of Science study, published today in Nature, found that the same holds true for blood vessels. The researchers discovered blood vessels forming from unexpected progenitors and went on to show that this unusual origin determines the vessels’ future function.
“We found that blood vessels must derive from the right source in order to function properly – it’s as if they remember where they came from,” says team leader Prof. Karina Yaniv.

Changing the Channel: Study Sheds New Light on a Promising Antidepressant

https://www.weizmann-usa.org/news-media/news-releases/changing-the-channel-study-sheds-new-light-on-a-promising-antidepressant/

May 31, 2022... REHOVOT, ISRAEL—May 31, 2022—Ketamine, a well-known anesthetic used in smaller doses as a party drug, was hailed as a “new hope for depression” in a Time magazine cover story in 2017. Two years later, the arrival of the first ketamine-based antidepressant – the nasal spray esketamine, made by Johnson & Johnson – was applauded as the most exciting development in the treatment of mood disorders in decades. Yet the U.S. Food and Drug Administration still limits the spray’s use. It is mainly given to depressed patients who have not been helped by other therapies – in part, because the new drug’s mechanism of action is insufficiently understood, leading to concerns over its safety.

Neurons Caught Rapidly Switching Gears
Neurons Caught Rapidly Switching Gears

https://www.weizmann-usa.org/news-media/news-releases/neurons-caught-rapidly-switching-gears/

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.

How do violence, trauma survivors develop resilience? - Israeli study
How do violence, trauma survivors develop resilience? - Israeli study

https://www.weizmann-usa.org/news-media/in-the-news/how-do-violence-trauma-survivors-develop-resilience-israeli-study/

Jan 25, 2023... 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.

Seeing Things Differently: The Secret Life of Our Eyes
Seeing Things Differently: The Secret Life of Our Eyes

https://www.weizmann-usa.org/news-media/feature-stories/seeing-things-differently-the-secret-life-of-our-eyes/

Jan 24, 2023... “Seeing eye to eye” is an expression of harmony, but do different people literally see the same things in the external world? “The short answer is – no,” says Dr. Liron Gruber. “Even the same person sees the same thing differently each time they look at it,” adds Prof. Ehud Ahissar.
After Weizmann mathematicians (headed by Prof. Shimon Ullman) established that a computer algorithm was much worse than humans at interpreting image fragments, Gruber and Ahissar built upon these findings. In an earlier study, they were able to show that, contrary to the widely accepted view, the human eye does not work like a camera, taking passive snapshots. In the new study, Gruber and Ahissar teamed up with computer scientist Ullman to put human vision to the test.
