“He is one of those dark matter people,” Mordehai Milgrom said about a colleague stopping by his office at the Weizmann Institute of Science. Milgrom introduced us, telling me that his friend is searching for evidence of dark matter in a project taking place just down the hall.
“There are no ‘dark matter people’ and ‘MOND people,’ ” his colleague retorted.

A wanderer strolling along an unfamiliar branching path faces a dilemma each time he reaches an intersection. Which way should he turn? Where should he be the next moment? Tracing the path of this random wanderer, one can try to make sense of the basic, underlying rules that direct his course. For instance, what happens if he simply chooses his direction on the basis of rolling dice?

Just as first impressions set the stage for the entire course of a relationship, first impressions set the stage for how the cells of our immune system react when meeting a new microbe, according to Israeli researchers at the Weizmann Institute of Science.
This new insight led the researchers to develop an algorithm that may predict the onset of such diseases as tuberculosis. Their findings were published July 22 in Nature Communications.

Nov 25, 2013... Chromosomes — the 46 tightly wrapped packages of genetic material in our cells — are iconically depicted as X-shaped formations. However, those neat X’s only appear when a cell is about to divide and the entire contents of its genome duplicated. Until now, researchers have not been able to get a good picture of the way that our DNA — some two meters of strands, all told — is neatly bundled into the nucleus while enabling day-to-day (non-dividing) gene activity. A combination of new techniques for sequencing DNA in individual chromosomes and analyzing data from thousands of measurements has given us a new picture of the three-dimensional (3D) structures of chromosomes. This method, reported recently in Nature, is the result of an international collaboration that promises to help researchers understand the basic processes by which gene expression is regulated and genome stability is maintained.

Gut bacteria may play a role in motor neurone disease ALS by speeding up progression, early studies reveal. The cruel condition that killed Professor Stephen Hawking, pictured
Gut bacteria could play a role in the development of motor neurone disease - also known as amyotrophic lateral sclerosis, early studies suggest.
Tests on mice showed a change in their gut microbe levels before symptoms of the crippling disorder appeared.

In the 1980s, Shafi Goldwasser co-invented “zero knowledge proofs,” a cryptographic breakthrough that, improbably, enables someone to prove a fact as true without revealing any information about that fact. For example, an investor seeking to prove her status as an accredited investor could demonstrate that her salary exceeds a certain minimum threshold while withholding the exact amount. (You can read more about the concept—one of the hottest area of research in the field of blockchain tech—in this Fortune feature from last year.)

The Israeli math team.
The team that represented Israel at the International Mathematical Olympiad in Santa Marta, Colombia, has won six medals – one gold, three silver, and two bronze. The Israeli team was ranked 13th among 97 participating countries.
Team members are “graduates” of national Olympiads – the Joseph Gillis National Math Olympiad for high school and the Zuta Math Olympiad for junior high school students – held at the Davidson Institute of Science Education, the educational arm of the Weizmann Institute of Science. The team took part in a two-week training camp in early June, as well as training sessions held over the three months that preceded the competition. They were coached by Lev Radzivilovsky, together with Prof. Dmitry Novikov of the Weizmann Institute’s Department of Mathematics.

(l-r) Profs. Ilan Koren, Yoav Schechner, and Klaus Schilling are inventing a new way of imaging clouds
REHOVOT, ISRAEL—December 17, 2018—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.

Mar 31, 2020... REHOVOT, ISRAEL—March 31, 2020—Think of dieting. You can fast for two months and lose weight, but you will probably die. Even if you survive, you will quickly gain weight again. Similarly, a two-month lockdown will suppress the coronavirus, but it will kill the economy. Lockdown will push hundreds of millions of people globally into unemployment and poverty. Many sectors of the economy will collapse. At the end of each lockdown, remaining patients will cause a resurge in the epidemic, forcing another lockdown.

Jupiter’s cloud bands — seen here in this image created by citizen scientists Gerald Eichstädt and Seán Doran, using data from NASA’s Juno spacecraft — extend more than 1,000 miles (1,600 kilometers) into the planet’s interior, three new studies suggest.

The colorful stripes of Jupiter run more than 1,000 miles deep and hold so much gas that their mass is about three times that of the entire Earth, three new studies find.
