Artificial intelligence probes dark matter in the universe

A team of physicists and computer scientists at ETH Zurich has developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves ...

Bigger cities boost 'social crimes'

As cities grow in size, crime grows even faster. But while certain types of crime—car theft and robbery, for example—exponentially outpace the population, other crime categories buck the trend. Rape, for example, grows ...

Laser prototype for space-based gravitational wave detector

Researchers have announced a prototype for a laser at the heart of the first space-based gravitational wave observatory, known as the Laser Interferometer Space Antenna (LISA) mission. The team's new laser nearly meets the ...

From primordial black holes new clues to dark matter

Primordial black holes (PBHs) are objects that formed just fractions of a second after the Big Bang, considered by many researchers among the principal candidates in explaining the nature of dark matter, above all following ...

A novel tool to probe fundamental matter

Identifying elementary constituents of matter including quarks, bosons and electrons, and the manner by which these particles interact with each other, constitutes one of the greatest challenges in modern physical sciences. ...

Hello, world! A new approach for physics in de Sitter space

For decades, physicists have been attempting to reconcile quantum mechanics, the physics of the very small, with gravity, the physics of the very large. While many academics are working on quantum gravity, they often use ...

Miniaturizing medical imaging, sensing technology

Scientists in Christine Hendon's and Michal Lipson's research groups at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis.
