Scientists at Tokyo Institute of Technology (Tokyo Tech) and Yokohama National University (YNU) have uncovered the peculiar mechanism by which spin perturbations travel through a seemingly unpassable region of a quantum spin liquid system. This new insight may represent another building block in next-generation electronics and even quantum computers. …

The 20th Anniversary of the Power Mac G4 Cube
Steven Levy from Wired remembers the Power Mac G4 Cube, which debuted July 19, 2000. From the report: I was reminded of this last week, as I listened to a cassette tape recorded 20 years prior, almost to the day. It documented a two-hour session with Jobs in Cupertino, California, shortly before the launch. The main reason he had summoned me…

Right to Repair Advocates Accuse Medical Device Manufacturers of Profiteering
A new Motherboard article interviews William, a ventilator refurbisher who’s repaired at least 70 broken ventilators that he’s bought on eBay and from other secondhand websites, then sold to U.S. hospitals and governments to help handle a spike in COVID-19 patients. He’s part of a grey-market supply chain that’s “essentially identical to one used by farmers to repair John Deere tractors…
Will Astronauts Ever Visit Gas Giants Like Jupiter?
Trying to get an up close and personal look at the solar system’s gas giants is a tricky and dangerous journey. From a report: Jupiter, like the other gas giants, doesn’t have a rocky surface, but that doesn’t mean it’s just a massive cloud floating through the vacuum of space. It’s made up of mostly helium and hydrogen, and as you…
The spin state story: Observation of the quantum spin liquid state in novel material
Aside from the deep understanding of the natural world that quantum physics theory offers, scientists worldwide are striving to bring forth a technological revolution by leveraging this newfound knowledge in engineering applications. Spintronics is an emerging field that aims to surpass the limits of traditional electronics by using the spin of electrons, which can be roughly seen as their angular rotation,…
