Paving the way for spintronic RAMs: A deeper look into a powerful spin phenomenon

Scientists at Tokyo Institute of Technology (Tokyo Tech) report a new material combination that sets the stage for magnetic random access memory based on spin, an intrinsic property of electrons. The innovation could outperform current storage devices. Their breakthrough, published in a new study, describes a novel strategy to exploit spin-related phenomena in topological materials and could spur several advances in the field of spin electronics. Moreover, this study provides additional insight into the underlying mechanism of spin-related phenomena.

Device splits and recombines superconducting electron pairs

A device that can separate and recombine pairs of electrons may offer a way to study an unusual form of superconductivity, according to RIKEN physicists. This superconducting state would involve exotic particles called Majorana fermions that could prove useful in developing quantum computers.

Astronomy & Space news

Deep eclipses detected in the cataclysmic variable J0130

Russian astronomer Valery Kozhevnikov has conducted photometric observations of the cataclysmic variable (CV) IPHAS J013031.89+622132.3 (J0130 for short), finding that the object exhibits deep eclipses. The discovery, presented in a paper published December 17 on arXiv.org, could provide more clues on the nature of this CV.

China to complete Beidou competitor to GPS with new launches

China said Friday its Beidou Navigation Satellite System that emulates the U.S. Global Positioning System will be competed with the launch of its final two satellites in the first half of next year.

Calculating the time it will take spacecraft to find their way to other star systems

A pair of researchers, one with the Max Planck Institute for Astronomy, the other with the Jet Propulsion Laboratory at CIT, has found a way to estimate how long it will take already launched space vehicles to arrive at other star systems. The pair, Coryn Bailer-Jones and Davide Farnocchia have written a paper describing their findings and have uploaded it to the arXiv preprint server.

China launches powerful rocket in boost for 2020 Mars mission

China Friday launched one of the world's most powerful rockets in a major step forward for its planned mission to Mars in 2020.

Waiting for Betelgeuse: what's up with the tempestuous star?

Have you noticed that Orion the Hunter—one of the most iconic and familiar of the wintertime constellations—is looking a little… different as of late? The culprit is its upper shoulder star Alpha Orionis, aka Betelgeuse, which is looking markedly faint, the faintest it has been for the 21st century.

Technology news

Japan revises Fukushima cleanup plan, delays key steps

Japan on Friday revised a roadmap for the cleanup of the tsunami-wrecked Fukushima nuclear plant, further delaying the removal of thousands of spent fuel units that remain in cooling pools since the 2011 disaster. It's a key step in the decadeslong process, complicated by high radiation and other risks. The government and the plant operator, Tokyo Electric Power Co., are keeping a 30- to 40-year completion target.

Turkey unveils national electric car prototypes

Turkish President Recep Tayyip Erdogan unveiled Friday prototypes of a domestically manufactured electric car that is hoped will hit the road within three years.

New Russian weapon can travel at 27 times the speed of sound

A new intercontinental weapon that can fly 27 times the speed of sound became operational Friday, Russia's defense minister reported to President Vladimir Putin, bolstering the country's nuclear strike capability.

Volkswagen raises forecast for electric car production

Automaker Volkswagen is accelerating its move into battery-powered cars, saying it will reach its goal of 1 million electric cars per year two years earlier than planned. Friday's announcement came as European automakers are under pressure to meet lower emissions limits aimed at fighting global warming.

Drones need huge tracking network for expanded flights, FAA says

All but the smallest civilian drones would have to broadcast radio tracking data to ensure greater safety and prevent terrorism under a sweeping proposal unveiled by U.S. regulators Thursday.

California is rewriting the rules of the internet and businesses are scrambling to keep up

A sweeping new law that aims to rewrite the rules of the internet in California is set to go into effect on Jan. 1.

Amazon/Deliveroo deal faces in-depth UK probe
