Researchers at the Weizmann Institute of Science in Rehovot, Israel, have discovered a new physics trick. While it's not exactly Superman vision — yet — the camera developed by Ori Katz, Eran Small and Prof. Yaron Silberberg sees through objects using a simple light bulb, a standard digital camera and the basic technology found in everyday digital projectors.

In October, LIGO and its European counterpart, VIRGO, witnessed gravitational waves rippling out from a breathtaking collision between two neutron stars. This unprecedented event looked like yet another triumph for a new kind of astronomy, one that could use gravitational waves to probe some of the universe’s deepest mysteries. But in all the excitement, most people didn’t notice that something had died: a whole group of theories that posit a universe with no dark matter.

Thirty-two-year-old Avital Dery, a doctoral student in physics at the Weizmann Institute of Science in Rehovot, was selected at the end of last week to represent Israel in the British Council’s prestigious international FameLab competition at the Cheltenham Science Festival next month.
She was selected from among five contestants by giving an excellent three-minute lecture in her scientific field. Dery is investigating elementary particles. She also sings and performs classical music throughout the country.

The long and complicated journey to detect the Higgs boson, which started with one small step about 25 years ago, might finally have reached its goal. This was reported by Large Hadron Collider (LHC) particle accelerator scientists on July 4 at the European Laboratory for Particle Physics, CERN, near Geneva.
Named after Scottish physicist Peter Higgs, the Higgs boson is the final building block that has been missing from the “Standard Model,” which describes the structure of matter in the universe. The Higgs boson combines two forces of nature and shows that they are, in fact, different aspects of a more fundamental force. The particle is also responsible for the existence of mass in the elementary particles.

Prof. Reshef Tenne
A report on a fundamentally new and unprecedented molecular closed-cage nanostructure, produced by immensely concentrated sunlight was published recently by a team combining researchers in Beersheba, Rehovot and Russia. Ben-Gurion University of the Negev Profs. Jeffrey Gordon and Daniel Feuermann, Prof. Reshef Tenne’s group at the Weizmann Institute of Science, and Dr. Andrey Enyashin at the Ural Federal University explained their work in a recent issue of one of the foremost journals in nanotechnology, ACS Nano.

Dec 16, 2009... The typical Hollywood action hero skirts death for a living. Time and again, scores of bad guys shoot at him from multiple directions but miss by a hair. Cars explode just a fraction of a second too late for the fireball to catch him before he finds cover. And friends come to the rescue just before a villain's knife slits his throat. If any one of those things happened just a little differently, the hero would be hasta la vista, baby. Yet even if we have not seen the movie before, something tells us that he will make it to the end in one piece.

The predicted property in this study is the velocity dispersion, which is the average velocity of objects within a galaxy relative to each other. Astronomers can use velocity dispersion to determine the accelerations of objects within the galaxy and, roughly, the mass of a galaxy, and vice-versa.
To calculate the velocity dispersion for each dwarf galaxy, the researchers utilized Modified Newtonian Dynamics, MOND for short, which is a hypothesis that attempts to resolve what appears to be an insufficient amount of mass in galaxies needed to support their orbital speeds.
Feb 04, 2010... REHOVOT, ISRAEL—February 4, 2010—The best way to track a moving object with a flashlight might be to aim it to one side, catching the object in the edge of the beam rather than the center. New research from the Weizmann Institute of Science reveals that bats, which "see" with beams of sound waves, skew their beams off-center when they want to locate an object. The research, which recently appeared in Science, shows that this strategy is the most efficient for locating objects.

An atomic clock – designed and constructed in Israel – will be carried beyond the Earth’s orbit as part of a mission planned by the European Space Agency (ESA).
The ESA mission, known as JUICE – JUpiter ICy moons Explorer – will spend at least three years making detailed observations of the solar system’s largest planet and three of its largest moons. Jupiter is known to have 67 moons.

Jun 01, 2012... Tiny particles such as atoms and electrons often behave in mysterious and surprising ways. Unlike larger objects composed of many particles, they can, for instance,exist simultaneously in more than one state. “According to the laws of quantum mechanics, a single atom can be in multiple locations at the same time and can be doing different things at the same time. We physicists call this the superposition principle,” says Dr. Roee Ozeri of the Weizmann Institute of Science’s Department of Physics of Complex Systems.
