When two (or three bodies of different sizes and distances) orbit a center point, it’s easy to calculate their movements using Newton's laws of motion. However, if all three objects are of a comparable size and distance from the center point, a power struggle develops and the whole system is thrown into chaos. When chaos happens, it becomes impossible to track the bodies’ movements using regular math. Enter the three-body problem.
Now, an international team, led by astrophysicist Dr. Nicholas Stone at the Hebrew University of Jerusalem’s Racah Institute of Physics, has taken a big step forward in solving this conundrum. Their findings were published in the latest edition of Nature.

In the past twenty years, both scientists’ understanding of the physical properties of quantum dots and their levels of control over these tiny particles have increased tremendously. This has led to a widespread application of quantum dots in our daily lives—from bio-imaging and bio-tracking (relying on the fact that quantum dots emit different colors based on their size) to solar energy and next-generation TV monitors with exceptional color quality.

A first-of-its-kind deep-sea research station placed 50km (31mi) from the Israeli shore called DeepLev which combines “deep” with the Israeli meaning for heart which is “lev”. Reaching a 1.5km depth (~1mi) it is set to shed new light on the eastern Mediterranean marine environment and the implications changes in this ecosystem hold for humans. The […]

Not all witches get the opportunity of going to Hogwart School of Witchcraft and Wizardry to polish their skills. Take my dad for example – a water witch from Newmarket, Canada. Maybe it is because he never made it past grade 8 or because he was never confident enough in his witching powers. Known as a […]

Urgent action is needed to address soil pollution and contain the multiple threats it poses to global food safety and food security, said FAO today marking World Soil Day. Thousands of chemicals, which are commercially produced on a large scale, plastic and electronic waste, non-treated wastewater can all become a source of soil pollution, paving […]

New research by Hebrew University of Jerusalem details the complex mathematical calculations that animals perform to locate their next meal. Turns out that even the simple earthworm constantly computes new scent data to see if they are on right track to food. Can humans learn from these tubular hermaphrodites?

New research from the University of East Anglia has confirmed a dramatic decrease in oxygen in the Gulf of Oman part of the Arabian Sea. But the environmental disaster is worse than expected. The ‘dead zone’ was confirmed by underwater robots called Seagliders – which were able to collect data in areas of water previously […]

Dust off old Donna Summer albums and celebrate the premature return of New Zealand’s giant “disco ball” satellite as it drops down to Earth from outer space. Just like the Age of Disco, it will completely disintegrate, leaving only groovy memories. The Humanity Star is a reflective satellite launched in January by Rocket Lab, a […]

American twins Scott (left) and Mark Kelly are the only identical twin astronauts in history, but after Scott spent nearly a year on a space mission, they may not be identical anymore. In 2016, when Scott Kelly returned to Earth after a 340-day voyage aboard the International Space Station (ISS), he was 2 inches taller […]

As if expecting women don’t have enough to worry about, a new scientific study indicates a direct correlation between traffic noise and ambient air pollution and the health of pregnant women and their birth outcomes. Specifically, these environmental influences are proving to increase the incidences of pre-eclampsia, gestational diabetes and low birth weights.
