Israel’s First Moon Mission Will Conduct Scientific Measurements
After an enterprise lasting nearly a decade, the Israeli unmanned Moon mission “Beresheet” (“Genesis” in Hebrew) will soon take off from Earth, bound for the Moon’s rocky surface. Prof. Oded Aharonson of the Weizmann Institute of Science’s Department of Earth and Planetary Sciences is head of the international science team, and will be watching closely as the craft approaches the Moon and initiates the scientific part of the mission, which will start well before touchdown.

All Too Human
Prof. Rony Paz of the Weizmann Institute of Science suggests that our brains are like modern washing machines – evolved to have the latest sophisticated programming, but more vulnerable to breakdown and prone to develop costly disorders. He and a group of researchers recently conducted experiments comparing the efficiency of the neural code in non-human and human primates and found that, as the neural code gets more efficient, the robustness that prevents errors is reduced. Their findings, which appeared in Cell, may help to explain why disorders as ADHD, anxiety, depression, PTSD, and even autism are common in humans.

Plants Blink: Proceeding with Caution in Sunlight
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.

Saturn’s Atmosphere Proves Deep, Its Rings Young
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.

The Immune System’s Fountain of Youth
Drug treatment eliminates senescent cells from tissues of old mice. The blue staining shows senescent cells in lung and liver tissue. The amount of the staining is significantly reduced following the drug treatment
If only we could keep our bodies young, healthy, and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future. The results of this research, led by Prof. Valery Krizhanovsky and Dr. Yossi Ovadya in the Department of Molecular Cell Biology, were recently published in Nature Communications. -

CT for Clouds: A Fleet of Micro-Satellites Will See Into the Smallest Clouds
Ten satellites, each around the size of a shoebox, are slated in a few years to enter orbit and begin filling in some gaping holes in our understanding of clouds and their role in climate. Inspired by medical CT (computed tomography), which observes and maps patients’ interiors, the designers are creating a system that will reveal detailed images of clouds’ external and internal 3D structures and properties. By probing small cloud fields that are generally missed by today’s remote-sensing technologies, the mission may resolve some major uncertainties that limit current atmospheric modelling and climate prediction.

The Importins of Anxiety
According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. In a study published in Cell Reports, researchers at the Weizmann Institute of Science have revealed a previously unknown mechanism underlying anxiety. Targeting this biochemical pathway may help develop new therapies to alleviate the symptoms of anxiety disorders.

Profiling a Killer in Warm Blood
Cancer arises when cells lose control. Deciphering the “blueprint” of cancer cells – outlining how cancer cells hijack specific pathways for uncontrolled proliferation – will lead to more efficient ways to fight it. Now, in a joint effort, scientists from the Weizmann Institute of Science and clinicians from major hemato-oncology departments in Israel have successfully created detailed profiles of myeloma cancer in both pre-cancer stages, in newly diagnosed multiple myeloma patients, as well as post-treatment and relapse. These detailed blueprints will help in future precision diagnosis and treatment of this disease.

Looking in Cellular Trash Cans
If we really want to know how our body’s cells work – or don’t work, in the case of disease – we might need to look beyond our genes and even beyond the proteins the genes are made of. We may need to start going through the cellular “trash.” The group of Dr. Yifat Merbl of the Weizmann Institute of Science developed a system to do just that, finding that “cellular dumpster-diving” contains information about the cell’s function that is not otherwise seen. The group applied their new approach to profiling the immune cells of patients with an autoimmune disorder, discovering clear evidence of a signature pattern that provides a new way of thinking about the underlying causes of the disease. Furthermore, in the future, this may lead to better diagnostic techniques.

Toward an “Ultra-Personalized” Therapy for Melanoma
With new immunotherapy treatments for melanoma, recovery rates have risen dramatically – in some cases to around 50%. But they could be much higher. A new study led by researchers at the Weizmann Institute of Science showed, in lab dishes and animal studies, that a highly personalized approach could help the immune cells improve their ability to recognize the cancer and kill it. The results of this study were published in Cancer Discovery.

An Inside Look at Probiotics
Every day, millions of people take probiotics – preparations containing live bacteria that are meant to fortify their immune systems, prevent disease, or repair the adverse effects of antibiotics. Yet the benefits of probiotics have not really been medically proven. It is not even clear if probiotic bacteria really colonize the digestive tract or, if they do, what effects the colonies have on humans and their microbiomes – the native bacteria in their guts. Now, in two back-to-back reports published in Cell, researchers at the Weizmann Institute of Science show – in both mice and in humans – that a preparation of 11 strains of the most widely used probiotic families may sometimes be less than beneficial for the user and their microbiome.

Light Exchange
The quantum computers of the future will be able to perform computations that cannot be done on today’s computers. These may likely include the ability to crack the encryption that is currently used for secure electronic transactions, as well as the means to efficiently solve unwieldy problems in which the number of possible solutions increases exponentially. Research in the quantum optics lab of Prof. Barak Dayan at the Weizmann Institute of Science may be bringing such computers one step closer by providing the “quantum gates” required for communication within and between such quantum computers.
