Wasted radio signals can be converted into electricity using a new kind of antenna rooted in how electrons behave at a quantum level.
A supermassive black hole in the center of the Milky Way galaxy is creating a light show that’s intriguing astronomers.
Flares of light have been observed in a disk orbiting the black hole Sagittarius A*, according to a team of astrophysicists studying the black hole who published their findings Tuesday in The Astrophysical Journal Letters. Known as an accretion disk, it’s hot, contains a steady flow of materials like gas or plasma, and flickers constantly. The disks emit light that can be detected using infrared and X-ray instruments, which helps astronomers better observe the black holes the disks orbit.
AI-designed chips are so weird that ‘humans cannot really understand them’ — but they perform better than anything we’ve created

AI models have, within hours, created more efficient wireless chips through deep learning, but it is unclear how their ‘randomly shaped’ designs were produced.
Experimental evidence for charge coupling to ferroelectric soft mode is scarce. Here, the authors find a photogenerated coherent phonon coupling to the electronicion above the bandgap in the van der Waals ferroelectric semiconductor NbOI2.
The USPTO’s Patent Trial and Appeal Board (PTAB) overturned an examiner’s rejection of a patent application from an inventor.
A brief guide to habits that separate deep understanding from superficial knowledge — and how to cultivate them.
This approach significantly enhances performance, as observed in Atari video games and several other tasks involving multiple potential outcomes for each decision.
“They basically asked what happens if rather than just learning average rewards for certain actions, the algorithm learns the whole distribution, and they found it improved performance significantly,” explained Professor Drugowitsch.
In the latest study, Drugowitsch collaborated with Naoshige Uchida, a professor of molecular and cellular biology at Harvard University. The goal was to gain a better understanding of how the potential risks and rewards of a decision are weighed in the brain.
