Universal Quantum Phenomenon Found in Superconductors
Posted by Genevieve Klien in categories: materials, quantum physics
Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.

Brain-Destroying Prions Also Spread Through Victims’ Eyes
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
One of the strangest things that can sicken us—a rogue misfolded protein that destroys the brain, known as a prion—is even scarier than we knew. Researchers were able to find the prions responsible for sporadic Creutzfeldt-Jakob disease (sCJD), the most common prion disease in people, seeded everywhere in the eyes of 11 patients affected by it.
The findings are the latest to suggest that these universally fatal, if rare, diseases can be spread through the eyes. But they also indicate that our eyes might be someday be used to spot these cases with less hassle than current testing methods.

Star spotted on the brink of a gamma ray burst – and it’s alarmingly close to Earth
Posted by Genevieve Klien in category: cosmology
With the power to unleash as much energy in 10 seconds as the Sun does in its entire lifetime, gamma-ray bursts (GRBs) are the most energetic events in the universe, second only to the Big Bang itself. Given how sudden they are, we don’t usually get any warning, but now astronomers have spotted the telltale signs of a star system that could blow its lid any moment – and it’s far too close to Earth for comfort.

A Universal Quantum Phenomenon in Strange Metals
Posted by Genevieve Klien in categories: particle physics, quantum physics
A ubiquitous quantum phenomenon has been detected in a large class of superconducting materials, fueling a growing belief among physicists that an unknown organizing principle governs the collective behavior of particles and determines how they spread energy and information.
