The properties of a complex and exotic state of a quantum material can be predicted using a machine learning method created by a RIKEN researcher and a collaborator. This advance could aid the development of future quantum computers.

We have all faced the agonizing challenge of choosing between two equally good (or bad) options. This frustration is also felt by fundamental particles when they feel two competing forces in a special type of quantum system.

In some magnets, particle spins—visualized as the axis about which a particle rotates—are all forced to align, whereas in others they must alternate in direction. But in a small number of materials, these tendencies to align or counter-align compete, leading to so-called frustrated magnetism. This frustration means that the spin fluctuates between directions, even at absolute zero temperature where one would expect stability. This creates an exotic state of matter known as a quantum spin liquid.

Researchers at Tel Aviv University detected 73% of the lies told by trial participants based on the contraction of their facial muscles – achieving a higher rate of detection than any known method.

Amazon is planning a satellite internet constellation that could rival SpaceX Starlink, touted by CEO Elon Musk as a means of getting more people online.

NASA scientists have issued a warning about a “Potentially Hazardous Asteroid” (PHA) that will fly close to earth in mid-December. The asteroid is larger than 90 percent of asteroids, according to Daily Record, but still smaller than some of the larger reported asteroids. Thankfully, the asteroid won’t come close enough to our planet to do any damage. Near passes like these happen somewhat frequently. But the term “near” is relative when you’re talking about the infinite vastness of outer space.

NASA predicts that the massive asteroid will pass by Earth on December 11, just a month and a few days from now. The asteroid has been classified as 4,660 Nereus, and NASA does consider it very hazardous. The organization says that the asteroid is almost three times the size of a football pitch — roughly the size of the Eiffel tower.

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity — spacetime. But if time is connected to space, could the universe be anything but deterministic? And does that mean that the future is predestined?

Cher sang about manipulating it while Doctor Who dramatized it. This hacker went one better and did it. Here’s how time got hacked.

During a 1961 address to the National Association of Manufacturers in New York City, John F. Kennedy said that “we must use time as a tool, not as a couch.” Fast forward fifty years, and one hacker has demonstrated exactly how to do that: by hacking time.

What is time anyway? What is time? That’s not an easy question to answer definitively.

With the potential to image fast-moving objects.

When asked what superpowers they would like to have, many say the ability to see through things. Now, there may be a camera that could give people that gift.

Developed by Northwestern Engineering researchers, the new high-resolution camera can see around corners and through human skin and even bones. It also has the potential to image fast-moving objects such as speeding cars or even the beating heart.

Happy birthday, ISS.

The first components of the International Space Station (ISS) were launched on November 20, 1998, roughly 12 years after the first Soviet MIR-2 module was launched and a full 25 years after Skylab.
