As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling through ancient Egypt that would later bear his name. It was a machine consisting of a screw housed inside a hollow tube that trapped and drew water upon rotation. Now, researchers led by Stanford University physicist Benjamin Lev have developed a quantum version of Archimedes’ screw that, instead of water, hauls fragile collections of gas atoms to higher and higher energy states without collapsing. Their discovery is detailed in a paper published Jan. 14 in Science.

“My expectation for our system was that the stability of the gas would only shift a little,” said Lev, who is an associate professor of applied physics and of physics in the School of Humanities and Sciences at Stanford. “I did not expect that I would see a dramatic, complete stabilization of it. That was beyond my wildest conception.”

Along the way, the researchers also observed the development of scar states—extremely rare trajectories of particles in an otherwise chaotic in which the particles repeatedly retrace their steps like tracks overlapping in the woods. Scar states are of particular interest because they may offer a protected refuge for information encoded in a quantum system. The existence of scar states within a quantum system with many interacting particles—known as a quantum many-body system—has only recently been confirmed. The Stanford experiment is the first example of the scar state in a many-body and only the second ever real-world sighting of the phenomenon.

The maker of a defunct cloud photo storage app that pivoted to selling facial recognition services has been ordered to delete user data and any algorithms trained on it, under the terms of an FTC settlement.

The regulator investigated complaints the Ever app — which gained earlier notoriety for using dark patterns to spam users’ contacts — had applied facial recognition to users’ photographs without properly informing them what it was doing with their selfies.

Under the proposed settlement, Ever must delete photos and videos of users who deactivated their accounts and also delete all face embeddings (i.e. data related to facial features which can be used for facial recognition purposes) that it derived from photos of users who did not give express consent to such a use.

WASHINGTON — SpaceX secured contracts Jan. 13 for the launches of a commercial lunar lander mission backed by NASA as well as a privately funded satellite to track methane emissions.

Intuitive Machines announced that it selected SpaceX for the launch of its IM-2 lunar lander mission on a Falcon 9 rocket no earlier than 2022. IM-2 will land in the south polar region of the moon carrying payloads arranged through the agency’s Commercial Lunar Payload Services (CLPS) program in October.

The IM-2 mission will fly a drilling experiment called Polar Resources Ice Mining Experiment 1 (PRIME-1), which will look for water ice below the lunar surface. Intuitive Machines said that, besides the PRIME-1 drill, two other NASA technology payloads will fly on the lander.

The Greater Reset, a conference being held online from January 25th — 29th, 2021, is the world’s collective response to the World Economic Forum’s Initiative: The Great Reset.

We offer an alternative to the WEF’s top-down, centralized, authoritarian vision. Our desire is to help all people find community and liberty by providing practical steps and knowledge for co-creating a world that respects individual liberty, bodily autonomy, and choice.

We invite you to join us for 5 days of online discussion about the diverse opportunities available for those who seek to live in harmony with humanity and the planet, while respecting our innate freedom.
