A new cryptographic system could allow pharmaceutical companies and academic labs to work together to develop new medications more quickly — without revealing any confidential data to their competitors.
The centerpiece of this computing system is an artificial intelligence program known as a neural network. The AI studies information about which drugs interact with various proteins in...
To help self-driving cars drive safely, scientists are looking to an unlikely place: the sea.
A new type of camera inspired by the eyes of mantis shrimps could help autonomous vehicles better gauge their surroundings, researchers report October 11 in Optica. The camera — which detects polarized light, or light waves vibrating on a single plane — has roughly half a million sensors that...
Blazingly fast lasers have just leveled up.
Ultrafast lasers emit short, rapid-fire bursts of light, with each pulse typically lasting tens of millionths of a billionth of a second. A new laser pulses 30 billion times a second — about 100 times as fast as most ultrafast lasers, researchers report in the Sept. 28 Science.
The speed boost was thanks to a new technique for making...
News in Brief
A new polymer-based paint that reflects nearly all incoming sunlight could help keep buildings, cars, airplanes and other sunbaked structures cool.
This polymer paint, described online September 27 in Science, can be applied to various surfaces, including plastics, metals and wood. It also could be fashioned into recyclable tarpaulins for covering homes, cars or other enclosed spaces....
Bernhard Riemann was a man with a hypothesis.
He was confident that it was true, probably. But he didn’t prove it. And attempts over the last century and a half by others to prove it have failed.
A new claim by the esteemed mathematician Michael Atiyah that Riemann’s hypothesis has now been proved may also be exaggerated. But sadly Riemann’s early death was not. He died at age 39....
A laser-shooting eye in the sky has revealed the previously unappreciated size and complexity of ancient Maya civilization, both before and during its presumed heyday, scientists say.
Maya people in what’s now northern Guatemala built surprisingly extensive defensive structures and roads as part of political systems featuring interconnected cities, starting at least several hundred years...
Much like a silkworm uses a single thread to swaddle itself in a cocoon, a new kind of robot spins a single strand of material around its body to build custom-shaped fiberglass structures.
The new robots could create customized construction materials on-site, unlike other industrious bots that assemble premade building blocks (SN: 3/22/14, p. 8). Fleets of the fiberglass-spinning bots...

The world is awash in data, and Anshumali Shrivastava may save us from drowning in it.
Every day, over 1 billion photos are posted online. In a single second, the Large Hadron Collider can churn out a million gigabytes of observations. Big data is ballooning faster than current computer programs can analyze it.

Scientists estimate that there are roughly 10 billion liters of liquid water beneath a polar glacier on Mars, Lisa Grossman reported in “Mars (probably) has a lake of liquid water” (SN: 8/18/18 & 9/1/18, p. 6).
Some online readers wondered what the detection meant for the possibility of life on the Red Planet.
Grossman wrote about the lake’s implications for life...
A famed mathematical enigma is once again in the spotlight.
The Riemann hypothesis, posited in 1859 by German mathematician Bernhard Riemann, is one of the biggest unsolved puzzles in mathematics. The hypothesis, which could unlock the mysteries of prime numbers, has never been proved. But mathematicians are buzzing about a new attempt.
Esteemed mathematician Michael Atiyah took a...
