Amazon and Apple ‘Not Playing Their Part’ in Tackling Electronic Waste
Global giants such as Amazon and Apple should be made responsible for helping to collect, recycle and repair their products to cut the 155,000 tonnes of electronic waste being thrown away each year in the UK, MPs say. From a report: An investigation by the environmental audit committee found the UK is lagging behind other countries and failing to create a…
Twisted Graphene Could Power a New Generation of Superconducting Electronics
sciencehabit shares a report from Science Magazine: In 2018, a group of researchers at the Massachusetts Institute of Technology (MIT) pulled off a dazzling materials science magic trick. They stacked two microscopic cards of graphene — sheets of carbon one atom thick — and twisted one ever so slightly. Applying an electric field transformed the stack from a conductor to an…
Faster magnetic switch with lower energy consumption developed
Magnetic materials are ubiquitous in modern society, present in nearly all the technological devices we use every day. In particular, personal electronics like smartphones/watches, tablets, and desktop computers all rely on magnetic material to store information. Information in modern devices is stored in long chains of 1’s and 0’s, in the binary number system used as the language of computers. …

Physicists develop efficient modem for a future quantum internet
The first quantum revolution brought about semiconductor electronics, the laser and finally the internet. The coming, second quantum revolution promises spy-proof communication, extremely precise quantum sensors and quantum computers for previously unsolvable computing tasks. But this revolution is still in its infancy. A central research object is the interface between local quantum devices and light quanta that enable the remote transmission…
