Quantum Algorithms Struggle Against Old Foe: Clever Computers
...the quantum algorithms that they believed were superior might turn out to be only ordinary. Sampling Struggle Until recently, the pursuit of quantum power was largely an abstract one. “We...
Solution: ‘Triangulation and Motion Sickness’
...lives throughout evolutionary history. But can’t the brain distinguish between motion sickness and poisoning? Such an ability could evolve, but motion sickness has only become common with the relatively recent...
How the Universe Got Its Bounce Back
...cycles (as in the cosmogonies of the Babylonians and Egyptians).” The division in modern cosmology “somehow parallels that of the cosmogonic myths,” Novello and Perez-Bergliaffa wrote. In recent decades, it...
Smart Swarms Seek New Ways to Cooperate
...researchers reported this inadvertent finding to their computer science collaborators, who seized on the clue. The work led to the recent development of the algorithm that will always get an...
Why Artificial Intelligence Like AlphaZero Has Trouble With the Real World
...peer reviewed and published in Science, and we have updated this article to reflect the latest information. Until very recently, the machines that could trounce champions were at least respectful...
The Simple Algorithm That Ants Use to Build Bridges
...feats that would make a four-star general proud, including building bridges with their own bodies. Much like the swarms of cheap, dumb robots that I explored in my recent article,...
To Test Einstein’s Equations, Poke a Black Hole
...at the University of California, Berkeley, and co-author, with András Vasy, of the other recent result. In 1916, almost immediately after Einstein released his theory of general relativity, the German...
The Brain Region That Controls Movement Also Guides Feelings
The cerebellum is responsible for far more than coordinating movement. New techniques reveal that it is, in fact, a hub of sensory and emotional processing in the brain. In recent...
How Einstein Lost His Bearings, and With Them, General Relativity
...proven especially acute for mathematicians who study the so-called black hole stability conjecture, which I wrote about in my recent article “To Test Einstein’s Equations, Poke a Black Hole.” Depending...
