Plants have control mechanisms that resemble those in human senses. According to a new Weizmann Institute of Science study, plants adjust their photosynthesis to rapid light changes using a sophisticated sensing system, much in the way that the human eye responds to variations in light intensity. This sensory-like regulation operates at low light intensities, when the photosynthesis machinery is most efficient but also most vulnerable to sudden light increases.

To expand the ties between the Israeli and Czech scientific communities, their countries are developing new forms of collaboration among talented young scientists. One such project is the “Joint Prague-Weizmann Winter School on Drug Discovery.” This intensive week of professional lectures is attended by more than 120 scientists and students from around the world. The project provides a unique opportunity for young Israeli and Czech researchers to meet and discuss the latest trends and challenges in drug development, as well as to meet with world leaders in academia and experts from such multinational pharmaceutical giants as MSD, Roche, and Astra Zeneca.

Under general relativity, a black hole is inescapable. Once something travels beyond the event horizon into the heart of the black hole, there’s no return. So intense is the gravitational force of a black hole that not even light - the fastest thing in the Universe - can achieve escape velocity.
Under general relativity, therefore, a black hole emits no electromagnetic radiation. But, as a young Stephen Hawking theorised in 1974, it does emit something when you add quantum mechanics to the mix.

Grand Finale was the official name of Cassini’s last act: a risky orbit between Saturn’s rings and atmosphere in a daring attempt to view the planet up close, just before going down in flames. Prof. Yohai Kaspi and Dr. Eli Galanti of the Weizmann Institute of Science’s Department of Earth and Planetary Sciences led one of the studies on Cassini’s final mission: revealing the depth of Saturn’s jet streams ‒ the strongest measured in the Solar System, with winds of up to 1,500 km (about 932 mi) per hour ‒ and found them to reach a depth of around 9,000 km (about 5,600 mi). Teaming up with research partners in Italy and the U.S., their study also helped reveal the age of the planet’s iconic rings. The findings of these studies were published in Science.

Tu B’Shevat, a Jewish holiday commemorating the importance and sanctity of trees, could not be more fitting in this day and age. Undoubtedly, it’s not easy to be a tree these days. Extended drought periods induced by climate change make it more and more difficult for those that need water to survive. Add to this the constant increase in pests and invasive species, one gets an idea of the grim reality in which many tree species are forced to survive the rapid and extreme changes.

As we take a moment to reflect on 2018, one thing is clear: the world needs science now more than ever. The past year was a time of flux, which makes us all the more grateful for Weizmann’s unchanging mission of “science for the benefit of humanity.” Scientific progress holds the promise of a better world – and here are just some of the breakthroughs from 2018 that inspire hope:
Prof. Ruth Arnon, renowned co-developer of Copaxone®, one of the world’s leading multiple sclerosis drugs, has developed a universal flu vaccine. The vaccine, which entered Phase III clinical trials in 2018, could protect people against all strains of the virus, for many years, in a single shot.
Israeli researchers recently made a discovery that could help develop new therapies for anxiety disorders. With up to one in three people around the world at the risk of experiencing severe anxiety, this is big news.
