More than 400 years after Galileo turned his telescope toward the planet Jupiter, the clouds and mist covering this giant of our Solar System are beginning to disperse. Since 1973, no fewer than six spacecraft have flown by Jupiter. But the Juno probe, launched in 2011 and in orbit around the planet since July 2016, is the first one equipped with systems that are able to reveal the secrets of Jupiter’s inner structure beneath the thick clouds.

It came in like a wrecking ball. Neptune has one of the weirdest collections of moons in our solar system, and it’s Triton’s fault. The planet’s largest moon probably smashed into the calm moon system that was there before it arrived, knocking everything out of sync.
Planetary scientists have long suspected that the huge moon Triton is an interloper from outside the Neptune system. Now they have calculated what the other moons may have looked like before the intrusion.

Sep 29, 2014... How the brain ages is still largely an open question – in part because this organ is mostly insulated from direct contact with other systems in the body, including the blood and immune systems. In research published recently in Science, Weizmann Institute researchers Prof. Michal Schwartz of the Department of Neurobiology and Dr. Ido Amit of the Department of Immunology found evidence of a unique “signature” that may be the “missing link” between cognitive decline and aging. The scientists believe that this discovery may, in the future, lead to treatments that can slow or reverse cognitive decline in older people.

To the south of the Great Dark Spot is the bright feature that Voyager scientists nicknamed "Scooter." Still farther south is the feature called "Dark Spot 2," which has a bright core. As each feature moves eastward at a different velocity, they are rarely aligned this way. Wind velocities near the equator are westward, reaching 1,300 km/h, while those at higher latitudes are eastward, peaking at 900 km/h. Image from the Voyager 2 flyby of Neptune in August 1989 (NASA)

For most of his life, Joshua Meier has been the textbook definition of a whiz kid. At four, he received his first computer game – a gift that fascinated him until he realized that the experience it created was “fundamentally limited.” Eager to push beyond those limitations, he opened his first email account when he was five and began programming at the age of eight.
His interests soon expanded to biology. By the time he was a high school junior in Teaneck, New Jersey, he was the head of a biotechnology company, Provita Pharmaceuticals, and had already gained recognition from Google for his stem cell research.

AJA Upper School students Shaun Regenbaum, Josh Bland, Josh Italiiander, Jonathan Bashary and Nittai Shiff are traveling to Israel from March 22 to 30 compete in the Shalhevet Freier International Physics Tournament at the Davidson Institute of Science Education at the Weizmann Institute in Rehovot.
The five students will design, build and operate a locking mechanism for a box, making it a safe, through the use of principles of physics. The mechanism could use lasers, wires, magnets and other elements.

The Weizmann Institute of Science lies in the heart of green vegetation.
The Institute was chosen several times by The Scientist magazine as one of “the best places to work in academia.”
Here you can find all kinds of researchers at work - some are trying to defeat cancer while others are creating materials never seen before.
In this lab, Professor Reshef Tenne and his team are creating tiny crystals called nanoparticles. Nanoparticles can only be created under laboratory conditions.

Weizmann Institute of Science and Hebrew University researchers have made the first direct visual observation and measurement of ultra-fast vortex dynamics in superconductors. They say their technique, detailed in the journal Nature Communications, could contribute to the development of novel practical applications by optimizing superconductor properties for use in electronics.

The weather forecast had predicted a cloudless day, but when Ilan Koren, an atmospheric scientist, looked up he saw small “cotton wool” clouds dotted across the bright blue sky over Israel.“Mystery” clouds like these are common on hot sunny days along humid sub-tropical shores, like those along the Mediterranean. Yet classical physics suggests these clouds shouldn’t exist. Now scientists think they might have finally solved the puzzle of how mystery clouds are made.Convection is the usual process that creates clouds on a hot sunny day. Warm air rises above warm regions of land (such as macadamed car parks, ploughed fields and coniferous forests). As the parcel of air rises it cools and its ability to hold moisture decreases. Eventually, if it rises high enough, it cannot hold any more water so droplets form and a fluffy cloud appears.But the clouds that Koren saw were a puzzle because they occurred below the predicted 100% humidity level. To understand these mystery clouds, Koren, based at the Weizmann Institute of Science, with his colleagues observed clouds and made regular measurements of changes in temperature and humidity at different altitudes. This was done over a 92-day period in the summer of 2011.Using these measurements they simulated the likely atmospheric mixing, and discovered that the mystery clouds were caused by variations in humidity not at ground surface but a few hundred metres up, perhaps where moist ocean air was mixing with dry land air. Normally cumulus clouds are caused by temperature variations on the ground surface.Writing in the journal Environmental Research Letters the scientists estimated that these previously misunderstood clouds could be responsible for reflecting up to 4 watts per square metre – equivalent to the local warming effect from greenhouse gases.
