Scientists from the universities of Alberta and Toronto developed a blueprint for a new quantum battery that doesn’t leak charge.

“A quantum battery is a tiny, nano-size battery meant to be used for applications on the nano scale,” explained U of A chemist Gabriel Hanna, who was principal investigator on the study.

He said the research provides a theoretical demonstration that creating a loss-free quantum battery is possible—offering an advantage over previously proposed quantum batteries.

Flying robots that deliver packages to people’s doorsteps are no longer science fiction. Companies including Amazon.com Inc., Alphabet Inc.’s Wing and Uber Technologies Inc. are starting the most advanced trials of drone delivery in U.S. history.

While commercial drone delivery faces many hurdles, government-approved tests by the tech giants will mark the first time consumers in parts of the country experience the technology. Wing this month started tests in Christiansburg, Va., while Uber says it will experiment in San Diego…

Facebook remains embroiled in a multibillion-dollar judgement lawsuit over its facial recognition practices, but that hasn’t stopped its artificial intelligence research division from developing technology to combat the very misdeeds of which the company is accused. According to VentureBeat, Facebook AI Research (FAIR) has developed a state-of-the-art “de-identification” system that works on video, including even live video. It works by altering key facial features of a video subject in real time using machine learning, to trick a facial recognition system into improperly identifying the subject.

This de-identification technology has existed in the past and there are entire companies, like Israeli AI and privacy firm D-ID, dedicated to providing it for still images. There’s also a whole category of facial recognition fooling imagery you can wear yourself, called adversarial examples, that work by exploiting weaknesses in how computer vision software has been trained to identify certain characteristics. Take for instance this pair of sunglasses with an adversarial pattern printed onto it that can make a facial recognition system think you’re actress Milla Jovovich.

Scientists have developed a new approach to cell-based therapies that can be triggered by a compound found in green tea.
