OpenAI has appointed ex-Twitch boss Emmett Shear to lead the startup, replacing Sam Altman who will join the company's top backer Microsoft to lead a new advanced AI research team, the CEO of the software giant said late on Sunday.

"We look forward to getting to know Emmett Shear and OAI's new leadership team and working with them," Microsoft CEO Satya Nadella posted on social media platform X. He added Microsoft remains committed to its partnership with OpenAI.

Shear was named interim CEO, a person briefed on the appointment told Reuters.

The decision not to reinstate Altman as CEO of the company behind ChatGPT has confounded efforts by investors and employees of the firm to steady the ship by bringing him back after the board fired him on Friday, a surprise move that rocked the tech world.

They fear his abrupt sacking could lead to a mass exodus of talent and impact an upcoming $86 billion share sale.

Nadella said Altman would join Microsoft to "lead a new advanced AI research team".

Reuters earlier reported that Altman was discussing a possible return to OpenAI and changing the company's governance structure, even as he considered launching a new AI venture.

Altman and Greg Brockman, who stepped down from the OpenAI board as chairman as part of the management shuffle, joined executives at the company's headquarters on Sunday after then interim CEO Mira Murati told staff she invited Altman, The Information earlier reported on Sunday.

Nadella said Brockman would also join the software company.

Altman posted an image of himself on X on Sunday wearing an OpenAI guest badge with the caption: "first and last time i ever wear one of these." In a separate post on X, he reshared Nadella's message with a comment "the mission continues".

Shear co-founded Twitch and had stepped down from the Amazon.com-owned live video streaming platform earlier this year.

Brockman quit over Altman's firing on Friday. Their departures blindsided many employees who discovered the abrupt management change from an internal message and the company's public blog.

Some researchers including Szymon Sidor have also left the company following the CEO change, two people familiar with the matter said. Sidor confirmed quitting.

The Information first reported the appointment of Shear as interim CEO.

Shortly after the internal announcement of Shear's appointment, distraught employees "streamed out" of OpenAI headquarters in San Francisco, The Information reported.

Dozens of staffers internally announced they were quitting the company on Sunday night, it said, citing a person with knowledge of the situation.

OpenAI kicked off the generative AI craze a year ago by releasing ChatGPT. The chatbot became one of the world's fastest-growing software applications.

Social media harms the mental health of adolescents, particularly girls, France's health watchdog said Tuesday as the country debates banning children under 15 from accessing the immensely popular platforms.

The results of an expert scientific review on the subject were announced after Australia became the first country to prohibit big platforms including Instagram, TikTok and YouTube for under 16s last month, while other nations consider following its lead.

Using social media is not the sole cause of the declining mental health of teenagers, but its negative effects are "numerous" and well documented, the French public health watchdog ANSES wrote in its opinion, the result of five years of work by a committee of experts.

France is currently debating two bills, one backed by President Emmanuel Macron, that would ban social media for under 15s.

The ANSES opinion recommended "acting at the source" to ensure that children can only access social networks "designed and configured to protect their health".

This means that the platforms would have to change their personalized algorithms, persuasive techniques and default settings, according to the agency.

"This study provides scientific arguments for the debate about social networks in recent years: it is based on 1,000 studies," the expert panel's head Olivia Roth-Delgado told a press conference.

Social media can create an "unprecedented echo chamber" that reinforces stereotypes, promotes risky behavior and promotes cyberbullying, the ANSES opinion said.

The content also portrays an unrealistic idea of beauty via digitally altered images that can lead to low self-esteem in girls, which creates fertile ground for depression or eating disorders, it added.

Girls -- who use social media more than boys -- are subjected to more of the "social pressure linked to gender stereotypes," the opinion said.

This means girls are more affected by the dangers of social media -- as are people with pre-existing mental health conditions, it added.

On Monday, tech giant Meta urged Australia to rethink its teen social media ban, while reporting that it has blocked more than 544,000 Instagram, Facebook and Threads accounts under the new law.

Meta said parents and experts were worried about the ban isolating young people from online communities, and driving some to less regulated apps and darker corners of the internet.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries.

The team expects the next generation of batteries to store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries.

The team has reported these results in the journal Advanced Science.

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries.

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point.

On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability.

To overcome these two obstacles, the team led by Mario El Kazzi, head of the Battery Materials and Diagnostics group at the Paul Scherrer Institute PSI, developed a new production process:

“We combined two approaches that, together, both densify the electrolyte and stabilize the interface with the lithium,” the scientist explained.

Central to the PSI study is the argyrodite type LPSCl, a sulphide-based solid electrolyte made of lithium, phosphorus, and sulphur. The mineral exhibits high lithium-ion conductivity, enabling rapid ion transport within the battery – a crucial prerequisite for high performance and efficient charging processes.

To densify argyrodite into a homogeneous electrolyte, El Kazzi and his team did incorporate the temperature factor, but in a more careful way: Instead of the classic sintering process, they chose a gentler approach in which the mineral was compressed under moderate pressure and at a moderate temperature of only about 80 degrees Celsius.

The result is a compact, dense microstructure resistant to the penetration of lithium dendrites. Already, in this form, the solid electrolyte is ideally suited for rapid lithium-ion transport.

To ensure reliable operation even at high current densities, such as those encountered during rapid charging and discharging, the all-solid-state cell required further modification.

For this purpose, a coating of lithium fluoride (LiF), only 65 nanometres thick, was evaporated under vacuum and applied uniformly to the lithium surface – serving as a ultra-thin passivation layer at the interface between the anode and the solid electrolyte.

In laboratory tests with button cells, the battery demonstrated extraordinary performance under demanding conditions.

“Its cycle stability at high voltage was remarkable,” said doctoral candidate Jinsong Zhang, lead author of the study.

After 1,500 charge and discharge cycles, the cell still retained approximately 75% of its original capacity.

This means that three-quarters of the lithium ions were still migrating from the cathode to the anode. “An outstanding result. These values are among the best reported to date.”

Zhang therefore sees a good chance that all-solid-state batteries could soon surpass conventional lithium-ion batteries with liquid electrolyte in terms of energy density and durability.

Thus El Kazzi and his team have demonstrated for the first time that the combination of solid electrolyte mild sintering and a thin passivation layer on lithium anode effectively suppresses both dendrite formation and interfacial instability.

This combined solution marks an important advance for all-solid-state battery research – not least because it offers ecological and economic advantages: Due to the low temperatures, the process saves energy and therefore costs.

“Our approach is a practical solution for the industrial production of argyrodite-based all-solid-state batteries,” said El Kazzi. “A few more adjustments – and we could get started.”
