OpenAI defends for-profit shift as critical to sustain humanitarian mission

Elon Musk may be the last obstacle to stop OpenAI’s for-profit shift.

OpenAI has finally shared details about its plans to shake up its core business by shifting to a for-profit corporate structure.

On Thursday, OpenAI posted on its blog, confirming that in 2025, the existing for-profit arm will be transformed into a Delaware-based public benefit corporation (PBC). As a PBC, OpenAI would be required to balance its shareholders' and stakeholders' interests with the public benefit. To achieve that, OpenAI would offer "ordinary shares of stock" while using some profits to further its mission—"ensuring artificial general intelligence (AGI) benefits all of humanity"—to serve a social good.

To compensate for losing control over the for-profit, the nonprofit would have some shares in the PBC, but it's currently unclear how many will be allotted. Independent financial advisors will help OpenAI reach a "fair valuation," the blog said, while promising the new structure would "multiply" the donations that previously supported the nonprofit.

Hertz continues EV purge, asks renters if they want to buy instead of return

Get a used Chevy Bolt for a bit over $18,000 or a 2023 Tesla Model 3 for a bit less.

Apparently Hertz's purging of electric vehicles from its fleet isn't going fast enough for the car rental giant. A Reddit user posted an offer they received from Hertz to buy the 2023 Tesla Model 3 they had been renting for $17,913.

Hertz originally went strong into EVs, announcing a plan to buy 100,000 Model 3s for its fleet by the end of 2021, but 16 months later had acquired only half that amount. The company found that repair costs—especially for Teslas, which averaged 20 percent more than other EVs—were cutting into its profit margins. Customer demand was also not what Hertz had hoped for; last January, it announced plans to sell off 20,000 EVs.

Asking its customers if they want to purchase their rentals isn't a new strategy for Hertz. "By connecting our rental customers who opt into our emails to our sales channels, we're not only building awareness of the fact that we sell arsenal but also offering a unique opportunity to someone who may be in the market for the same car they have on rent," Hertz communications director Jamie Line told The Verge.

Could microwaved grapes be used for quantum sensing?

Halved grapes boost magnetic fields, paving way for alternative microwave resonators for quantum sensing devices.

There are thousands of YouTube videos in which DIY science enthusiasts cut grapes in half—leaving just a thin bit of skin connecting them—and put the grapes in the microwave, just to marvel at the sparks and plume of ionized gas (plasma) that the grapes produce. This quirky property of grapes might help make more efficient quantum sensors, according to a new paper published in the journal Physical Review Applied.

The plasma-inducing grape effect was first observed in 1994, per the authors. As previously reported, the usual explanation for the generation of plasmas is that grapes are so small that the irradiating microwaves become highly concentrated in the grape tissue, ripping some the molecules apart to generate charged ions (adding to the electrolytes already present in the grapes). The electromagnetic field that forms causes ions to flow from one grape half to the other via the connecting skin—at least at first. That's when you get the initial sparks. Eventually, the ions start passing through the surrounding air as well, ionizing it to produce that hot plume of plasma.

But in 2019, Trent University scientists showed that explanation isn't quite right. The skin bridge isn't necessary for the effect to occur. Rather, the plasma is generated by an electromagnetic "hot spot." The grapes have the right refractive index and size to "trap" microwaves, so putting two of them close together leads to the generation of a hot spot between them. The trick also works with gooseberries, large blackberries, and quail eggs, as well as hydrogel beads—plastic beads soaked in water. ("Many microwaves were in fact harmed during the experiments," co-author Hamza Khattak admitted at the time.)

FTC launches probe of Microsoft over bundling

Redmond’s packing of Office with security, cloud computing services under scrutiny.

The Federal Trade Commission is investigating Microsoft in a wide-ranging probe that will examine whether the company’s business practices have run afoul of antitrust laws, according to people familiar with the matter. In recent weeks, FTC attorneys have been conducting interviews and setting up meetings with Microsoft competitors.

One key area of interest is how the world’s largest software provider packages popular Office products together with cybersecurity and cloud computing services, said one of the people, who asked not to be named discussing a confidential matter.

This so-called bundling was the subject of a recent ProPublica investigation, which detailed how, beginning in 2021, Microsoft used the practice to vastly expand its business with the US government while boxing competitors out of lucrative federal contracts.
