Optical brain-like chip processes almost 2 billion images per second

Researchers at the University of Pennsylvania have developed a powerful new optical chip that can process almost 2 billion images per second. The device is made up of a neural network that processes information as light without needing components that … Continue reading Optical brain-like chip processes almost 2 billion images per second

EPFL’s super-fast 3D-printing technique makes resin objects in seconds

Researchers at EPFL have demonstrated a light-based 3D-printing method that’s about 30 times faster than conventional additive manufacturing, creating objects in 20 seconds that would normally take more like 10 minutes thanks to photocurable resins.Con… Continue reading EPFL’s super-fast 3D-printing technique makes resin objects in seconds

NASA’s new solar sail design bends light to propel spacecraft efficiently

NASA has selected a fascinating new project for further development, known as the Diffractive Solar Sail. By bending light before it hits the sail, this device could propel spacecraft more efficiently than conventional propulsion technologies.Continue … Continue reading NASA’s new solar sail design bends light to propel spacecraft efficiently

World’s smallest gears measure mere nanometers to power molecular machines

In many fields of technology, smaller is better, and machinery is now getting so tiny it’s measured in mere atoms. Researchers at the University of Erlangen–Nuremberg (FAU) in Germany have now developed what they claim are the world’s smallest working … Continue reading World’s smallest gears measure mere nanometers to power molecular machines

Scientists calculate absolute quantum speed limit for electronics

It often feels like electronics will continue to get faster forever, but at some point the laws of physics will intervene to put a stop to that. Now scientists have calculated the ultimate speed limit – the point at which quantum mechanics prevents mic… Continue reading Scientists calculate absolute quantum speed limit for electronics

Sleep lab study finds sleeping with a light on harms heart health

Researchers from Northwestern University’s Feinberg School of Medicine have found sleeping in a moderately lit room can potentially harm a person’s cardiometabolic health. The study saw just one night of sleep in a room with moderate ambient light incr… Continue reading Sleep lab study finds sleeping with a light on harms heart health
