Japan’s TDK is claiming a breakthrough in materials used in its small solid-state batteries, with the Apple supplier predicting significant performance increases for devices from wireless headphones to smartwatches.

The new material provides an energy density—the amount that can be squeezed into a given space—of 1,000 watt-hours per liter, which is about 100 times greater than TDK’s current battery in mass production. Since TDK introduced it in 2020, competitors have moved forward, developing small solid-state batteries that offer 50 Wh/l, while rechargeable coin batteries using traditional liquid electrolytes offer about 400 Wh/l, according to the group.

“We believe that our newly developed material for solid-state batteries can make a significant contribution to the energy transformation of society. We will continue the development towards early commercialisation,” said TDK’s chief executive Noboru Saito.

Brussels is set to charge Apple over allegedly stifling competition on its mobile app store, the first time EU regulators have used new digital rules to target a Big Tech group.

The European Commission has determined that the iPhone maker is not complying with obligations to allow app developers to “steer” users to offers outside its App Store without imposing fees on them, according to three people with close knowledge of its investigation.

The charges would be the first brought against a tech company under the Digital Markets Act, landmark legislation designed to force powerful “online gatekeepers” to open up their businesses to competition in the EU.

Tesla shareholders will vote on Thursday on whether to restore the mammoth pay package for chief executive Elon Musk that was struck down by a Delaware judge this year. But that is not expected to close the book on a legal saga that has consumed the electric-car maker and the leading US business law court that dared to defy Musk and his overseers on the company’s board.

In asking shareholders to approve of the same 2018 pay package that was nullified by the Delaware Court of Chancery in January, Tesla is relying on a legal principle known as “ratification,” in which the validity of a corporate action can be cemented by a shareholder vote. Ratification, the company told shareholders in a proxy note earlier this year, “will restore Tesla’s stockholder democracy.”

This instance, however, is the first time a company has tried to leverage that principle after its board was found to have breached its fiduciary duty to approve the deal in the first place.

Artificial intelligence heavyweights in California are protesting against a state bill that would force technology companies to adhere to a strict safety framework including creating a “kill switch” to turn off their powerful AI models, in a growing battle over regulatory control of the cutting-edge technology.

The California Legislature is considering proposals that would introduce new restrictions on tech companies operating in the state, including the three largest AI start-ups OpenAI, Anthropic, and Cohere as well as large language models run by Big Tech companies such as Meta.

The bill, passed by the state’s Senate last month and set for a vote from its general assembly in August, requires AI groups in California to guarantee to a newly created state body that they will not develop models with “a hazardous capability,” such as creating biological or nuclear weapons or aiding cyber security attacks.

The resurrection of a car plant in Brazil’s poor northeast stands as a symbol of China’s global advance—and the West’s retreat.

BYD, the Shenzhen-based conglomerate, has taken over an old Ford factory in Camaçari, which was abandoned by the American automaker nearly a century after Henry Ford first set up operations in Brazil.

When Luiz Inácio Lula da Silva, Brazil’s president, visited China last year, he met BYD’s billionaire founder and chair, Wang Chuanfu. After that meeting, BYD picked the country for its first carmaking hub outside of Asia.

OpenAI has revealed operations linked to Russia, China, Iran and Israel have been using its artificial intelligence tools to create and spread disinformation, as technology becomes a powerful weapon in information warfare in an election-heavy year.

The San Francisco-based maker of the ChatGPT chatbot said in a report on Thursday that five covert influence operations had used its AI models to generate text and images at a high volume, with fewer language errors than previously, as well as to generate comments or replies to their own posts. OpenAI’s policies prohibit the use of its models to deceive or mislead others.

The content focused on issues “including Russia’s invasion of Ukraine, the conflict in Gaza, the Indian elections, politics in Europe and the United States, and criticisms of the Chinese government by Chinese dissidents and foreign governments,” OpenAI said in the report.

The US government is nearing an agreement to bankroll a late-stage trial of Moderna’s mRNA pandemic bird flu vaccine, hoping to bolster its pandemic jab stockpile as an H5N1 outbreak spreads through egg farms and among cattle herds.

The federal funding from the government’s Biomedical Advanced Research and Development Authority, known as BARDA, could come as early as next month, according to people close to the discussions.

It is expected to total several tens of millions of dollars and could be accompanied by a commitment to procure doses if the phase-three trials are successful, they said.

When the Brazilian nutritional scientist Carlos Monteiro coined the term “ultra-processed foods” 15 years ago, he established what he calls a “new paradigm” for assessing the impact of diet on health.

Monteiro had noticed that although Brazilian households were spending less on sugar and oil, obesity rates were going up. The paradox could be explained by increased consumption of food that had undergone high levels of processing, such as the addition of preservatives and flavorings or the removal or addition of nutrients.

But health authorities and food companies resisted the link, Monteiro tells the FT. “[These are] people who spent their whole life thinking that the only link between diet and health is the nutrient content of foods ... Food is more than nutrients.”
