Scientists are closing in on turning hydrogen into a metal

Like modern day alchemists, scientists are attempting to transform a common element into a precious metal. This isn’t about making lead into gold, but turning elemental hydrogen into a different, never before seen form of hydrogen. Scientists are tantalizingly close to producing the first samples of solid metallic hydrogen using …

The Large Hadron Collider is running out of disk space

The Large Hadron Collider (LHC) has run into an unanticipated problem — it’s running out of disk space. “This year the LHC is stable and reliable,” says Jorg Wenninger, head of operations at the LHC. “It is working like clockwork. We don’t have much downtime.” That’s actually the problem. When …

Scientists develop a memristor that can be conditioned just like a real synapse

An international collaboration of researchers from UMass Amherst, HP, and the Air Force have built a proof-of-concept memristor that could lead to real-world neuromorphic chips. The memristor is made of a silicon-oxygen-nitrogen material laced with clumps of silver nanoparticles at the electrical terminals. When current is applied across the memristor, the silver nanoparticles shuffle around …

LIGO’s black hole detection survives the gravastar test

Ever since the historic discovery of gravitational waves by the Laser Interferometry Gravitational wave Observatory (LIGO), scientists have been trying to amend and refine that data. The original idea was that the first confirmed detection of gravitational waves was the result of a binary black hole event: two black holes …
