Scientists have created a light as thin as paper that emits a gentle, natural glow similar to sunlight.
By using a precise mix of quantum dots, the team reproduced the full color range of daylight. The design could lead to more comfortable, eye-friendly lighting and next-generation display screens.
Paper-Thin Breakthrough in LED Technology.
The complex dance of two black holes locked in a doomed orbit has been revealed in a first-of-its-kind direct radio image.
It’s the first time astronomers have directly imaged the distinct jets of both black holes in a known binary – finally confirming the model of the double core of a galaxy called OJ 287.
In OJ 287, located some 3.5 billion light-years away, the intricate, extreme interplay between the two central supermassive black holes has been documented for decades. This is the first image to capture smoking-gun signatures of both objects, however.
Cybersecurity researchers are calling attention to a new campaign that delivers the Astaroth banking trojan that employs GitHub as a backbone for its operations to stay resilient in the face of infrastructure takedowns.
“Instead of relying solely on traditional command-and-control (C2) servers that can be taken down, these attackers are leveraging GitHub repositories to host malware configurations,” McAfee Labs researchers Harshil Patel and Prabudh Chakravorty said in a report.
“When law enforcement or security researchers shut down their C2 infrastructure, Astaroth simply pulls fresh configurations from GitHub and keeps running.”
