Firefox To Ship ‘Network Partitioning’ As a New Anti-Tracking Defense
An anonymous reader quotes a report from ZDNet: Firefox 85, scheduled to be released next month, in January 2021, will ship with a feature named Network Partitioning as a new form of anti-tracking protection. The feature is based on “Client-Side Storage Partitioning,” a new standard currently being developed by the World Wide Web Consortium’s Privacy Community Group. “Network Partitioning is highly…
A Group of Materials Called Perovskites Could Be a Game-Changer For Solar Power
Researchers from Australia have discovered that the widely acclaimed mineral perovskite can be used to transform the solar industry through cheaper and more efficient photovoltaics. The Independent reports: Perovskite, which is forged deep within the Earth’s mantle, has been hailed for its unprecedented potential to convert sunlight into electricity. Researchers have already improved its sunlight-to-energy efficiency from around 3 per cent…
How One Piece of Hardware Took Down a $6 Trillion Stock Market
An anonymous reader quotes a report from Bloomberg on how a data storage and distribution device brought down Tokyo’s $6 trillion stock market: At 7:04 a.m. on an autumn Thursday in Tokyo, the stewards of the world’s third-largest equity market realized they had a problem. A data device critical to the Tokyo Stock Exchange’s trading system had malfunctioned, and the automatic…
Justice Department Asks Judge To Allow US To Bar WeChat From US App Stores
The U.S. Justice Department asked a federal judge in San Francisco early on Friday to allow the government to bar Apple and Google from offering WeChat for download in U.S. app stores pending an appeal. From a report: The filing asked U.S. Magistrate Judge Laurel Beeler to put on hold her preliminary injunction issued Saturday. That injunction blocked the U.S. Commerce…
Researchers manipulate two bits in one atom
Researchers at Delft University of Technology have succeeded in independently manipulating two different types of magnetism within a single atom. The results are relevant for the development of extremely small forms of data storage. In time, this new discovery could make it possible to store two bits of information in one atom. …
CIA Declassifies Cold War-Era Plans for a ‘Nuclear Bird Drone’
“During the Cold War, the CIA considered building a bird-sized drone designed to spy on the communist bloc,” reports Popular Mechanics. “The drone would carry ‘black box’ spy packages into Russia and China, as well as take secret photographs — all while hiding in plain sight disguised as a bird…” The project envisioned a fleet of 12 bird-shaped drones, powered by…
Researchers Use DNA to Store ‘The Wizard of Oz’ – Translated Into Esperanto
“DNA is millions of times more efficient at storing data than your laptop’s magnetic hard drive,” reports Popular Mechanics. “Since DNA can store data far more densely than silicon, you could squeeze all of the data in the world inside just a few grams of it.” In a new paper published this week in the journal Proceedings of the National Academy…
Spintronics Researchers Demonstrate How to Process Magnetic Vortices for Data Storage
Research continues in a field which involves using the spin and magnetism of electrons in solid-state devices — spintronics. hackingbear shared this report from Nature:
Electric control of magnetic vortex dynamics in a reproducible way on an ultrafast time scale is a key element in the quest for efficient spintronic devices with low-energy consumption. Researchers in China and Germany demonstrated a simple…
Introducing the light-operated hard drives of tomorrow
What do you get when you place a thin film of perovkite material used in solar cells on top of a magnetic substrate? More efficient hard drive technology. EPFL physicist László Forró and his team pave the way for the future of data storage. …
