Newly discovered “standard sirens” provide an independent, clean way to measure how fast the universe is expanding.
To efficiently analyze a firehose of data, scientists first have to break big numbers into bits.
Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.
Minor genetic changes can have big evolutionary consequences. When a gene duplication gave some water striders a novel leg part, it opened up a new world for them.
A new version of AlphaGo needed no human instruction to figure out how to clobber the best Go player in the world — itself.
