Advances make high-density, 5D optical storage practical for long-term data archiving.

Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000 times denser than Blue-Ray optical disc storage technology.

“Individuals and organizations are generating ever-larger datasets, creating the desperate need for more efficient forms of data storage with a high capacity, low energy consumption and long lifetime,” said doctoral researcher Yuhao Lei from the University of Southampton in the UK. “While cloud-based systems are designed more for temporary data, we believe that 5D data storage in glass could be useful for longer-term data storage for national archives, museums, libraries or private organizations.”

Like many other companies, Adobe is leveraging deep learning to improve its applications and solidify its position in the video and image editing market. In turn, the use of AI is shaping Adobe’s product strategy.

AI-powered image and video editing

Sensei, Adobe’s AI platform, is now integrated into all the products of its Creative Cloud suite. Among the features revealed in this year’s conference is an auto-masking tool in Photoshop, which enables you to select an object simply by hovering your mouse over it. A similar feature automatically creates mask layers for all the objects it detects in a scene.

Facebook founder Mark Zuckerberg accused other tech companies of “stifling innovation” with high fees and little choice for consumers during a live stream on Thursday, all while his company faces an antitrust lawsuit from the federal government and heightened pressure from Congress over recently-leaked internal documents

Zuckerberg made the comments at the Facebook Connect event Thursday, where he announced the company has changed its name to Meta.

He also laid out the company’s plans to build a metaverse — a virtual reality experience where people can meet online. His comments seemed to allude to mobile operating systems like those created by Apple and Google, though he did not mention any company by name or specify the types of platforms he was talking about.

Will drone deliveries be a practical part of our future? We visit the test facilities of Wing to check out how their engineers and aircraft designers have developed a drone and drone fleet control system that is actually in operation today in parts of the world. Here’s how their VTOL drone works and what it’s like to both load and receive a package carried by an autonomous aircraft!

For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments.

The international team, led by the University of Cambridge, found that instead of starting from a single point in the brain and initiating a chain reaction that leads to the death of brain cells, Alzheimer’s disease reaches different regions of the brain early. How quickly the disease kills cells in these regions, through the production of toxic protein clusters, limits how quickly the disease progresses overall.

The researchers used post-mortem brain samples from Alzheimer’s patients, as well as PET scans from living patients, who ranged from those with mild cognitive impairment to those with late-stage Alzheimer’s disease, to track the aggregation of tau, one of two key proteins implicated in the condition.
