A proposed device can repeatedly grab pairs of electrons from a superconductor and separate them while preserving their entangled state.

Researchers have made a landmark discovery in quantum physics by observing and quantitatively characterizing the many-body pairing pseudogap in unitary Fermi gases, a topic of debate for nearly two decades. This finding not only resolves long-standing questions about the nature of the pseudogap in these gases but also suggests a potential link to the pseudogap observed in high-temperature superconductors.

Researchers have conclusively observed the many-body pairing pseudogap in unitary Fermi gases, advancing our understanding of superconductivity mechanisms.

A research team led by Professors Jianwei Pan, Xingcan Yao, and Yu’ao Chen from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, has for the first time observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases.

Jenniskens’ collaborators at the Museum für Naturkunde officially announced that the first examinations of one of these pieces with an electron beam microprobe prove the typical mineralogy and chemical composition of an achondrite of the aubrite type.

The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites.”

“They were devilishly difficult to find because, from a distance, they look like other rocks on Earth,” said SETI Institute meteor astronomer Dr. Peter Jenniskens. “Close up, not so much.”

A protective layer applied to gold nanoparticles can boost its resilience.

For the first time, researchers including those at the University of Tokyo discovered a way to improve the durability of gold catalysts by creating a protective layer of metal oxide clusters. The enhanced gold catalysts can withstand a greater range of physical environments compared to unprotected equivalent materials.

Dr. Hanan Herzig Sheinfux, from Bar-Ilan University: “What started as a chance discovery, may well open the way to new quantum applications, pushing the boundaries of what we thought was possible.”

In a significant leap forward for quantum nanophotonics, a team of European and Israeli physicists, introduces a new type of polaritonic cavities and redefines the limits of light confinement. This pioneering work, detailed in a study published today (February 6) in Nature Materials, demonstrates an unconventional method to confine photons, overcoming the traditional limitations in nanophotonics.

Physicists have long been seeking ways to force photons into increasingly small volumes. The natural length scale of the photon is the wavelength and when a photon is forced into a cavity much smaller than the wavelength, it effectively becomes more “concentrated.”

NinjaOne, a startup offering tools to manage and secure endpoints in enterprise settings, has raised $231.5 million at a $1.9 billion valuation.

In new images captured by NASA’s Juno spacecraft, fiery volcanic activity is seen erupting across Jupiter’s moon, Io.

Io is the third-largest of Jupiter’s four Galilean moons and is the most volcanically active celestial body in our solar system, with roughly 400 active volcanos, according to the agency.

Marking the second flyby of Jupiter’s scorching moon in the last 22 years, NASA’s orbiter came within about 930 miles of Io and captured two twin volcanic plumes spewing into space from the moon’s surface.
