Bioinspired phototransistor achieves high-sensitivity detection of low-contrast targets

Drawing inspiration from the remarkable adaptability of the human eye, researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed a novel phototransistor with tunable sensitivity.

This breakthrough provides an efficient solution for detecting low-contrast targets in complex visual environments, which is a critical challenge for advanced machine vision systems in applications such as precision guidance and smart surveillance.

The results are published in Light: Science & Applications.

Mystery Solved? Fast Radio Bursts Linked to Orbiting Stellar Companions

Astronomers have found compelling evidence that at least some fast radio bursts originate from stars in binary systems rather than from isolated objects. An international group of astronomers, including a researcher from the Department of Physics at The University of Hong Kong (HKU), has identifi

Scientists Say a Major Quantum Computing Breakthrough Was Not What It Seemed

Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far beyond today’s computers, but it faces a stubborn obstacle: quantum information is extremely frag

This Quantum Breakthrough Could Change How Materials Are Made

Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather than blasting them with intense light. Imagine being able to change what a material is capable of simply by shining light on it. That idea may sound like something out of s

The World’s Longest-Running Lab Experiment Is Almost 100 Years Old

Sometimes science can be painfully slow. Data comes in dribs and drabs, truth trickles, and veracity proves viscous.

The world’s longest-running lab experiment is an ongoing work in sheer scientific patience. It has been running continuously for nearly a century, under the close supervision of several custodians and many spectators – and it’s ever so slowly drip, drip, dripping away.

It all started in 1927, when physicist Thomas Parnell at the University of Queensland in Australia filled a closed funnel with the world’s thickest known fluid: pitch, a derivative of tar that was once used to seal ships against the seas.

Polar Storms on Jupiter And Saturn Reveal Deep Atmospheric Differences

The two largest planets in the Solar System – Jupiter and Saturn – have a lot in common. They’re made of very similar stuff, they spin at similar speeds, and radiate internal heat similarly. Heck, they even both hoard moons in a similar way.

However, there’s a difference between the planets that has long puzzled scientists: the giant, vortical storms that cap their poles.

Saturn has one huge storm on each pole.
