Applying quantum computing to a particle process

A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN’s Large Hadron Collider. …

Mars atmosphere shedding charged particles onto Phobos?

New research suggests that particles escaping from Mars’ atmosphere have been accumulating on the surface of the planet’s largest moon Phobos for billions of years. They could provide important new details about the history of both worlds. Source: https://earthsky.org/space/mars-atmosphere-history-phobos-soil…

The US Government’s Entire 645,000-Vehicle Fleet Will Go All-Electric

Jalopnik reports:
The United States government operates a fleet of about 645,000 vehicles, from mail delivery trucks to military vehicles and passenger cars. On Monday, President Joe Biden announced that his administration intends to replace them all with American-made, electric alternatives… In 2015, the government operated 357,610 gasoline vehicles and 3,896 electric ones; in 2019, those numbers grew to 368,807 and 4,475,…

Exchange bias set in a spin-glass phase could arise in a disordered antiferromagnet

A team of researchers from the University of California, Lawrence Berkeley National Laboratory, the Nuclear Research Center—Negev and the National High Magnetic Field Laboratory has developed a way to isolate antiferromagnet (AFM) heterostructures in the absence of a ferromagnet (FM) to study the coupling that occurs between AFM order parameters and spin-glass parameters. In their paper published in the journal Nature…

X-rays surrounding ‘Magnificent 7’ may be traces of sought-after particle

A new study, led by a theoretical physicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Rediscovering RISC-V: Apple M1 Sparks Renewed Interest in Non-x86 Architecture

“With the runaway success of the new ARM-based M1 Macs, non-x86 architectures are getting their closeup,” explains a new article at ZDNet. “RISC-V is getting the most attention from system designers looking to horn-in on Apple’s recipe for high performance. Here’s why…” RISC-V is, like x86 and ARM, an instruction set architecture (ISA). Unlike x86 and ARM, it is a free…

DoorDash Is Hiking Customer Fees To Pay For a Law It Helped Write

An anonymous reader quotes a report from Motherboard: In the months since a coalition of app-based gig companies successfully passed Prop 22 in California, exempting themselves from reclassifying their workers as employees, DoorDash has been silently passing costs onto consumers. The company-funded Yes on Prop 22 campaign claimed that not passing the ballot initiative would result in higher prices for consumers,…

Dark storm on Neptune changes direction, escapes deadly fate

Astronomers used the Hubble Space Telescope to observe unusual weather on the planet Neptune, not observed until now. They saw a large, dark storm on Neptune unexpectedly changing direction, thereby saving itself from looming destruction and possibly producing a smaller companion storm.
