Sony Music is sending warning letters to more than 700 artificial intelligence developers and music streaming services globally in the latest salvo in the music industry’s battle against tech groups ripping off artists.

The Sony Music letter, which has been seen by the Financial Times, expressly prohibits AI developers from using its music—which includes artists such as Harry Styles, Adele and Beyoncé—and opts out of any text and data mining of any of its content for any purposes such as training, developing or commercializing any AI system.

Sony Music is sending the letter to companies developing AI systems including OpenAI, Microsoft, Google, Suno, and Udio, according to those close to the group.

Brussels has opened an in-depth probe into Meta over concerns it is failing to do enough to protect children from becoming addicted to social media platforms such as Instagram.

The European Commission, the EU’s executive arm, announced on Thursday it would look into whether the Silicon Valley giant’s apps were reinforcing “rabbit hole” effects, where users get drawn ever deeper into online feeds and topics.

EU investigators will also look into whether Meta, which owns Facebook and Instagram, is complying with legal obligations to provide appropriate age-verification tools to prevent children from accessing inappropriate content.

On a fall evening in 2022, scientists at the Johns Hopkins University Applied Physics Laboratory were busy with the final stages of a planetary defense mission. As Andy Rivkin, one of the team leaders, was getting ready to appear in NASA’s live broadcast of the experiment, a colleague posted a photo of a pair of asteroids: the half-mile-wide Didymos and, orbiting around it, a smaller one called Dimorphos, taken about 7 million miles from Earth.

“We were able to see Didymos and this little dot in the right spot where we expected Dimorphos to be,” Rivkin recalled.

After the interview, Rivkin joined a crowd of scientists and guests to watch the mission’s finale on several big screens: As part of an asteroid deflection mission called DART, a spacecraft was closing in on Dimorphos and photographing its rocky surface in increasing detail.

Billy Restey is a digital artist who runs a studio in Seattle. But after hours, he hunts for rare chunks of bitcoin. He does it for the thrill. “It’s like collecting Magic: The Gathering or Pokémon cards,” says Restey. “It’s that excitement of, like, what if I catch something rare?”

In the same way a dollar is made up of 100 cents, one bitcoin is composed of 100 million satoshis—or sats, for short. But not all sats are made equal. Those produced in the year bitcoin was created are considered vintage, like a fine wine. Other coveted sats were part of transactions made by bitcoin’s inventor. Some correspond with a particular transaction milestone. These and various other properties make some sats more scarce than others—and therefore more valuable. The very rarest can sell for tens of millions of times their face value; in April, a single sat, normally worth $0.0006, sold for $2.1 million.

Brussels is set to issue new antitrust charges against Microsoft over concerns that the software giant is undermining rivals to its videoconferencing app Teams.

According to three people with knowledge of the move, the European Commission is pressing ahead with a formal charge sheet against the world’s most valuable listed tech company over concerns it is restricting competition in the sector.

Microsoft last month offered concessions as it sought to avoid regulatory action, including extending a plan to unbundle Teams from other software such as Office, not just in Europe but across the world.

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible matter, despite those laws working well everywhere in the Solar System.

To prevent galaxies from flying apart, some additional gravity is needed. This is why the idea of an invisible substance called dark matter was first proposed. But nobody has ever seen the stuff. And there are no particles in the hugely successful Standard Model of particle physics that could be the dark matter—it must be something quite exotic.

This has led to the rival idea that the galactic discrepancies are caused instead by a breakdown of Newton’s laws. The most successful such idea is known as Milgromian dynamics or Mond, proposed by Israeli physicist Mordehai Milgrom in 1982. But our recent research shows this theory is in trouble.

Global carmakers are stepping up their investment in hybrid technologies as consumers’ growing wariness over fully electric vehicles forces the industry to rapidly shift gear, according to top executives.

A combination of still high interest rates and concern over inadequate charging infrastructure has chilled buyers’ enthusiasm for fully electric cars, prompting a rebound in sales of hybrid vehicles that most of the industry had long regarded as nothing more than a stop-gap.

Tapping the resurgent demand for hybrids was a priority, executives from General Motors, Nissan, Hyundai, Volkswagen and Ford told the Financial Times’ Future of the Car Summit this week.

If you puncture the ovary of a wasp called Microplitis demolitor, viruses squirt out in vast quantities, shimmering like iridescent blue toothpaste. “It’s very beautiful, and just amazing that there’s so much virus made in there,” says Gaelen Burke, an entomologist at the University of Georgia.

M. demolitor  is a parasite that lays its eggs in caterpillars, and the particles in its ovaries are “domesticated” viruses that have been tuned to persist harmlessly in wasps and serve their purposes. The virus particles are injected into the caterpillar through the wasp’s stinger, along with the wasp’s own eggs. The viruses then dump their contents into the caterpillar’s cells, delivering genes that are unlike those in a normal virus. Those genes suppress the caterpillar’s immune system and control its development, turning it into a harmless nursery for the wasp’s young.

The insect world is full of species of parasitic wasps that spend their infancy eating other insects alive. And for reasons that scientists don’t fully understand, they have repeatedly adopted and tamed wild, disease-causing viruses and turned them into biological weapons. Half a dozen examples already are described, and new research hints at many more.

An advert by Apple for its new iPad tablet showing musical instruments, artistic tools, and games being crushed by a giant hydraulic press has been attacked for cultural insensitivity in an online backlash.

The one-minute video was launched by Apple chief executive Tim Cook to support its new range of iPads, the first time that the US tech giant has overhauled the range for two years as it seeks to reverse faltering sales.

The campaign—soundtracked by Sonny and Cher’s 1971 hit All I Ever Need Is You—is designed to show how much Apple has been able to squeeze into the thinner tablet. The ad was produced in-house by Apple’s creative team, according to trade press reports.

About five miles south of Broken Bow, in the heart of central Nebraska, thousands of cattle stand in feedlots at Adams Land & Cattle Co., a supplier of beef to the meat giant Tyson Foods.

From the air, the feedlots look dusty brown and packed with cows—not a vision of happy animals grazing on open pastureland, enriching the soil with carbon. But when the animals are slaughtered, processed, and sent onward to consumers, labels on the final product can claim that they were raised in a “climate friendly” way.

In late 2022, Tyson—one of the country’s “big four” meat packers—applied to the US Department of Agriculture (USDA), seeking a “climate friendly” label for its Brazen Beef brand. The production of Brazen Beef, the label claims, achieves a “10 percent greenhouse gas reduction.” Soon after, the USDA approved the label.

Most scammers and cybercriminals operate in the digital shadows and don’t want you to know how they make money. But that’s not the case for the Yahoo Boys, a loose collective of young men in West Africa who are some of the web’s most prolific—and increasingly dangerous—scammers.

Thousands of people are members of dozens of Yahoo Boy groups operating across Facebook, WhatsApp, and Telegram, a WIRED analysis has found. The scammers, who deal in types of fraud that total hundreds of millions of dollars each year, also have dozens of accounts on TikTok, YouTube, and the document-sharing service Scribd that are getting thousands of views.

“Join Your Local Militia or III% Patriot Group,” a post urged the more than 650 members of a Facebook group called the Free American Army. Accompanied by the logo for the Three Percenters militia network and an image of a man in tactical gear holding a long rifle, the post continues: “Now more than ever. Support the American militia page.”

Other content and messaging in the group is similar. And despite the fact that Facebook bans paramilitary organizing and deemed the Three Percenters an “armed militia group" on its 2021 Dangerous Individuals and Organizations List, the post and group remained up until WIRED contacted Meta for comment about its existence.

Free American Army is just one of around 200 similar Facebook groups and profiles, most of which are still live, that anti-government and far-right extremists are using to coordinate local militia activity around the country.

The need for long-duration energy storage, which helps to fill the longest gaps when wind and solar are not producing enough electricity to meet demand, is as clear as ever. Several technologies could help to meet this need.

But which approaches could be viable on a commercial scale?

Toronto-based Hydrostor Inc. is one of the businesses developing long-duration energy storage that has moved beyond lab scale and is now focusing on building big things. The company makes systems that store energy underground in the form of compressed air, which can be released to produce electricity for eight hours or longer.
