A team from the US Northwestern University has developed a laser that changes colours using the same mechanism as chameleons. “Chameleons can easily change their colours by controlling the spacing among the nano-crystals on their skin, which determines the colour we observe,” said Professor Teri Odom. “This colouring based on surface structure is chemically stable ...

Coolisys Technologies has announced a line of crypto-mining units, called ‘SuperMiner’. The first of the line, built around a 10nm mining chipset jointly developed by Samsung and Innosilicon, is called ‘AntEater’ and can operate at 17.2T hash/s. “We wanted to push the envelope by developing the AntEater based on a 10nm chip because it was the ...

Novel laser scans could scan breast for cancer without x-rays, if research at Caltech proves fruitful. Photoacoustic computed tomography, or PACT, works by shining a near-infrared laser pulse into the breast tissue, which is absorbed by oxygen-carrying hemoglobin molecules in red blood cells, causing the molecules to vibrate ultrasonically. Those vibrations travel through the tissue and ...

Korean research lab KAIST has created a flexible array of thin-film blue micro-LEDs, following-on form a similar red array. The team transferred thousands of <2μm-thick blue vertical micro LEDs onto plastic in one go. Electrical connections are via silver wires. Optical power density around 30mW/mm2 was demonstrated. claimed by KAIST to be three times higher that ...

Non-centralised mutual control is key to a team of drones that can defend a place against attack, according to researchers in Saudi Arabia. Performance of the scheme was judged in a capture-the-flag game, where the team of defender drones worked together within a defined area to intercept a human-controlled intruder drone and prevent it from reaching ...

Computer scientists from the University of Bonn have developed software that can predict human behaviour a few minutes into the future, demonstrated by asking ‘what happens next’ when people make salads. The training data included 40 videos of people making different salads, each around six minutes long and containing 20 different actions on average, lasting ...
