The Social Benefits of Getting Our Brains in Sync
...might have been literally true. Dozens of recent experiments studying the brain activity of people performing and working together — duetting pianists, card players, teachers and students, jigsaw puzzlers and...
Dark Energy May Be Weakening, Major Astrophysics Study Finds
...Digital Sky Survey (SDSS), which relied on similar fibers that had to be plugged into patterned metal plates by hand. On one recent record-setting night, DESI was able to record...
Number of Distances Separating Points Has a New Bound
...(In two dimensions, the threshold is precisely d/2 + 1/4.) This latest result is just one in a wave of recent advances on Falconer’s conjecture. The proof refined techniques in...
Viruses Finally Reveal Their Complex Social Life
...absurd at all. In recent decades, they have discovered some strange features of viruses that don’t make sense if viruses are lonely particles. They instead are uncovering a marvelously complex...
AI Starts to Sift Through String Theory’s Near-Endless Possibilities
...networks, the computer programs powering advances in artificial intelligence. In recent months, two teams of physicists and computer scientists have used neural networks to calculate precisely for the first time...
To Pack Spheres Tightly, Mathematicians Throw Them at Random
...research fields. Nearly all of the lower bounds to how densely spheres can be packed have come from studying latticelike structures. But the recent paper uses graph theory to create...
AI Needs Enormous Computing Power. Could Light-Based Chips Help?
...ways forward involves processing information not with trusty electrons, which have dominated computing for over 50 years, but instead using the flow of photons, minuscule packets of light. Recent results...
Cryptographers Discover a New Foundation for Quantum Secrecy
...possible with quantum cryptography,” said Henry Yuen, a quantum information theorist at Columbia University. In a string of recent papers, researchers have shown that most cryptographic tasks could still be...
Computation Is All Around Us, and You Can See It if You Try
...way to manage this randomness and complexity? The recent progress we have seen in artificial intelligence through machine learning gives us a glimpse into what it would mean to do...
