"A UK-based startup has used an AI algorithm to identify a previously unknown kind of rare-earth free magnet, in a potential breakthrough for how we discover and create new materials. Materials Nexus, headquartered in London, used its machine learning algorithm to identify and analyse over 100 million combinations of materials that could produce a viable rare-earth free magnet."

" Meta apologises over flood of gore, violence and dead bodies on Instagram Users of Reels report feeds dominated by violent and graphic footage after apparent algorithm malfunction Dan Milmo Global technology editor Fri 28 Feb 2025 15.01 GMT Share Mark Zuckerberg's Meta has apologised after Instagram users were subjected to a flood of violence, gore, animal abuse and dead bodies on their Reels feeds. Users reported the footage after an apparent malfunction in Instagram's algorithm, which curates what people see on the app. Reels is a feature on the social media platform that allows users to share short videos, similar to TikTok."

"computer programs can accelerate discovery in the sciences faster than scientists can, if the computer is trained to behave like one"

"For now, however, Hammond tries to reassure journalists that he's not trying to kick them when they're down. He tells a story about a party he attended with his wife, who's the marketing director at Chicago's fabled Second City improv club. He found himself in conversation with a well-known local theater critic, who asked about Hammond's business. As Hammond explained what he did, the critic became agitated. Times are tough enough in journalism, he said, and now you're going to replace writers with robots? "I just looked at him," Hammond recalls, "and asked him: Have you ever seen a reporter at a Little League game? That's the most important thing about us. Nobody has lost a single job because of us.""

"Uber knows when your phone battery is running low because its app collects that information in order to switch into power-saving mode. But Chen swears Uber would never use that knowledge to gouge you out of more money. "We absolutely don't use that to kind of like push you a higher surge price, but it's an interesting kind of psychological fact of human behavior," Chen said. Uber's surge pricing uses a proprietary algorithm that accounts for how many users are hailing rides in an area at a given time. Customers are apparently less willing to believe that when the multiplier is a round number like 2.0 or 3.0, which seems more like it could have been arbitrarily made up by a human."

The ensuing controversy has sparked renewed debates about the ways in which algorithms can perpetuate biases, yielding unintended and often offensive results.

"Amazon's algorithms encourage customers pay more than they need to for popular products and appear to give more prominence to items that benefit the retail giant, according to an investigation by ProPublica. The investigation looked at 250 frequently purchased products over several weeks to see which ones were chosen to appear in the highly-prized "buy box" that pops up first as a suggested purchase. "

"How can you sort the books quickly? Chand John shows how, shedding light on how algorithms help librarians and search engines speedily sort information."

"This algorithm uses a recurrent neural network to predict sound features from videos and then produces a waveform from these features with an example-based synthesis procedure. We show that the sounds predicted by our model are realistic enough to fool participants in a "real or fake" psychophysical experiment, and that they convey significant information about material properties and physical interactions."

"Not everything is so straightforward in Google land, as Google's chat protocols Hangouts and Talk, suffered a privacy issue on the 26 September that saw instant messages routed to unintended recipients."

"Having a site that is friendly to mobile browsers on smartphones and tablets will be key from Tuesday as Google rolls out a new mobile-focused algorithm. The update to the way Google ranks search results will take into account how mobile-friendly a website is. This means companies without a good mobile website will suffer, as searchers on mobile will see sites with good mobile experiences ranked higher than those with no mobile or poor mobile sites."

"What you may not realize, though, is that machine learning is already all around you, and it can exert a surprising degree of influence over your life. Don't believe me? You might be surprised."

"Twitter claims a 90 percent accuracy rate for the clever techniques it uses to learn the gender of any given user. Glenn Fleishman reports on a the company's disconcerting new analytics tools, the research behind them, and how large a pinch of salt they come with."

"With all the information together, they created a prediction model which can guess with 80% accuracy whether or not that user will go on to be banned from just their first five posts. "

"It's highly unlikely investigative or intelligence agencies have much of an interest in protecting the privacy of non-targeted citizens, even in non-terrorist-related surveillance -- not if it means using alternate (read: "less effective") investigative methods or techniques. It has been demonstrated time and time again that law enforcement is more interested in the most direct route to what it seeks, no matter how much collateral damage is generated. "

""Could teaching be trumped by a learning machine? Are we beginning to glimpse the possibility of machines that teach themselves to teach? They learn what works, what doesn't and deliver ever better performance. We see the embryonic evidence for this in adaptive learning systems, that are truly algorithmic, and do use machine learning, to improve as they deliver. The more students they teach, the better they get. They even tech themselves. This is not science fiction. This is real AI, in real software, delivering real courses, in real institutions." - Donald Clark"

"There is little evidence to show algorithms by online firms are based on politics, and many conservatives - including Trump himself - have large a social media following. Analysts say it would be dangerous to try to regulate how search engines work to please a government or political faction."

"Amid mounting financial pressure, at least a dozen police forces are using or considering predictive analytics, despite warnings from campaigners that use of algorithms and "predictive policing" models risks locking discrimination into the criminal justice system."

"Algorithms steer us back to similar content in echo chambers that inhibit both critical and creative thinking. Platforms incentivized to keep users scrolling discourage long-looking and render users as passive consumers, rather than active seekers of inspiration. They aren't a space for productive feedback, either: Art takes on a different tone when it's surrounded by dog GIFs, political memes, and your cousin's baby photos."
