By cooling atoms to ultra-cold temperatures, researchers can watch interactions in slow motion and the results are giving them a new perspective into the behaviour of matter at the quantum level.
The closer you look at something, the more strangely it behaves. The smallest known particles, such as photons and electrons, follow their own rules of behaviour described as quantum physics.

Ten moons have been discovered orbiting Jupiter – 9 “normal” outer ones and an “oddball” – scientists from the Carnegie Institution for Science in Washington reported on Tuesday.
Including the previously unknown moons, Jupiter now has 79 known moons orbiting the giant planet, more than any other planet in our Solar System. Saturn has the second highest number of known moons: 61.

The ions in the center of the cluster are cooled to the lowest temperatures, and can then be further accelerated in the ion beam trap
When investigating atoms, scientists face a challenge: at room temperature, individual atoms in a gas have kinetic energy, and fly around at high velocities. Temperature is, in essence, the relative movement between atoms; thus, the goal of getting the atoms to have small relative velocities involves freezing them to extremely cold temperatures. Now, a group at the Weizmann Institute of Science has developed a new universal method for cooling ions.

This graphic shows galaxy NGC 7610 (top right), where the supernova SN2013fs exploded. The event was detected by the Palomar Transient Factory sky survey (bottom right) a mere 3 hours after explosion. The detection was so rapid that researchers could image the circumstellar material (middle left) that surrounded the exploded star. (Ofer Yaron)
It was a type II supernova, the kind that occurs when a massive star evolves into a red supergiant, like the star Betelgeuse. In their waning days, these huge, (relatively) cool bodies start to unravel, expelling huge amounts of their mass until they are surrounded by shells of dense gas called circumstellar material, or CSM.

Touchdown: Rossetta mission crew celebrate
The first ever landing of a man-made probe onto a comet has been named Physics World Breakthrough of the Year for 2014.
From a shortlist of 10 highly commended breakthroughs, the historic achievement by scientists working on the Rosetta mission was singled out by the Physics World editorial team for its significance and fundamental importance to space science.

GENEVA — In a way, the worst thing that could have happened for physicists at CERN, the world's largest particle physics research center, was discovering the holy grail of physics — the so-called God particle, also known as Higgs boson.
Because after finding it in July 2012 — and confirming it six months later, after almost 50 years of searching — what else is left? The anti-climax was inevitable.

From the galactic to the quantum, the science of invisibility is revealing new ways to manipulate the world, said Professor Ulf Leonhardt, from Israel’s Weizmann Institute, after giving a presentation at TEDxBrussels on 1 December.
You discussed the science of invisibility during your presentation, and in your European Research Council (ERC)-funded research you are linking theoretical physics with invisibility, but what does that mean in practice?

Jul 06, 2016... The Weizmann Institute's most important asset is its people. That's why the Institute is committed to recruiting and nurturing some of the world's brightest young researchers. Here, six impressive new scientists – Drs. Ronen Eldan, Ofer Firstenberg, Yifat Merbl, Neta Regev-Rudzki, Nir London, and Efi Efrati – share how the Institute is helping them make breakthroughs in areas ranging from malaria to optics.

In a warmer climate, storms that start to build over the oceans at mid-latitudes will both form and reach peak strength closer to the poles, potentially bringing harsher weather to some heavily populated areas.
Earth’s mid-latitudes commonly experience cyclonic storms, which are large-scale, low-pressure systems that can produce strong gales, thunderstorms and, unlike tropical cyclones, rapid drops in temperature. To determine how the tracks of these storms might change in a warmer world, Talia Tamarin-Brodsky and Yohai Kaspi at the Weizmann Institute of Science in Rehovot, Israel, compared historical climate model simulations for 1980–1999 with projections for 2080–2099.

REHOVOT, ISRAEL—July 25, 2012—The imaging potential of cutting-edge microscopes will soon be expanded thanks to Weizmann Institute inventions. A licensing agreement for developing these inventions into commercial products has been signed recently between Yeda, Weizmann’s technology transfer arm, and Intelligent Imaging Innovations (3i) in the United States.
