Cast your mind back to 2021. Electric vehicles were hot stuff, buoyed by Tesla’s increasingly stratospheric valuation and a general optimism fueled by what would turn out to be the most significant climate-focused spending package in US history. For some time, automakers had been promising an all-electric future, and they started laying the groundwork to make that happen, partnering with battery suppliers and the like.

Take Ford—that year, it announced a joint venture with SK to build a pair of battery factories, one in Kentucky, the other in Tennessee. BlueOvalSK represented an $11.4 billion investment that would create 11,000 jobs, we were told , and an annual output of 60 GWh from both plants.

Four years later, things look very different. EV subsidies are dead, as is any inclination by the current government to hold automakers accountable for selling too many gas guzzlers. EV-heavy product plans have been thrown out, and designs for new combustion-powered cars are being dusted off and spiffed up. Fewer EVs means a need for fewer batteries, and today we saw that in evidence when it emerged that Ford and SK On are ending their battery factory joint venture.

Since the 1990s, physicists have pondered the tantalizing possibility of an exotic fourth type of neutrino, dubbed the “sterile” neutrino, that doesn’t interact with regular matter at all, apart from its fellow neutrinos, perhaps. But definitive experimental evidence for sterile neutrinos has remained elusive. Now it looks like the latest results from Fermilab’s MiniBooNE experiment have ruled out the sterile neutrino entirely, according to a paper published in the journal Nature.

How did the possibility of sterile neutrinos even become a thing? It all dates back to the so-called “solar neutrino problem.” Physicists detected the first solar neutrinos from the Sun in 1966. The only problem was that there were far fewer solar neutrinos being detected than predicted by theory, a conundrum that became known as the solar neutrino problem. In 1962, physicists discovered a second type (“flavor”) of neutrino, the muon neutrino . This was followed by the discovery of a third flavor, the tau neutrino , in 2000.

Physicists already suspected that neutrinos might be able to switch from one flavor to another. In 2002 , scientists at the Sudbury Neutrino Observatory (or SNO) announced that they had solved the solar neutrino problem. The missing solar (electron) neutrinos were just in disguise, having changed into a different flavor on the long journey between the Sun and the Earth. If neutrinos oscillate, then they must have a teensy bit of mass after all. That posed another knotty neutrino-related problem. There are three neutrino flavors, but none of them has a well-defined mass. Rather, different kinds of “mass states” mix together in various ways to produce electron, muon, and tau neutrinos. That’s quantum weirdness for you.

On Thursday, The Walt Disney Company announced a $1 billion investment in OpenAI and a three-year licensing agreement that will allow users of OpenAI’s Sora video generator to create short clips featuring more than 200 Disney, Marvel, Pixar, and Star Wars characters. It’s the first major content licensing partnership between a Hollywood studio related to the most recent version of OpenAI’s AI video platform, which drew criticism from some parts of the entertainment industry when it launched in late September.

“Technological innovation has continually shaped the evolution of entertainment, bringing with it new ways to create and share great stories with the world,” said Disney CEO Robert A. Iger in the announcement. “The rapid advancement of artificial intelligence marks an important moment for our industry, and through this collaboration with OpenAI we will thoughtfully and responsibly extend the reach of our storytelling through generative AI, while respecting and protecting creators and their works.”

The deal creates interesting bedfellows between a company that basically defined modern US copyright policy through congressional lobbying back in the 1990s and one that has argued in a submission to the UK House of Lords that useful AI models cannot be created without copyrighted material.

Oracle stock dropped after it reported disappointing revenues on Wednesday alongside a $15 billion increase in its planned spending on data centers this year to serve artificial intelligence groups.

Shares in Larry Ellison’s database company fell 11 percent in pre-market trading on Thursday after it reported revenues of $16.1 billion in the last quarter, up 14 percent from the previous year, but below analysts’ estimates.

Oracle raised its forecast for capital expenditure this financial year by more than 40 percent to $50 billion. The outlay, largely directed to building data centers, climbed to $12 billion in the quarter, above expectations of $8.4 billion.

One of the world’s premier security organizations has canceled the results of its annual leadership election after an official lost an encryption key needed to unlock results stored in a verifiable and privacy-preserving voting system.

The International Association of Cryptologic Research (IACR) said Friday that the votes were submitted and tallied using Helios , an open source voting system that uses peer-reviewed cryptography to cast and count votes in a verifiable, confidential, and privacy-preserving way. Helios encrypts each vote in a way that assures each ballot is secret. Other cryptography used by Helios allows each voter to confirm their ballot was counted fairly.

An “honest but unfortunate human mistake”

Per the association’s bylaws, three members of the election committee act as independent trustees. To prevent two of them from colluding to cook the results, each trustee holds a third of the cryptographic key material needed to decrypt results.

A man in Ireland earned the unpleasant distinction of developing an exceedingly rare infection on his penis—one that has a puzzling origin, but may be connected to his work with dead animals.

According to an article published in ASM Case Reports on Thursday, the 57-year-old man went to a hospital in Dublin after his penis became red, swollen, and painful over the course of a week. He also had a fever. Doctors promptly admitted him to the hospital and noted that he had received a kidney transplant 15 years prior. As such, he was on immunosuppressive drugs, which keep his body from rejecting the organ, but could also allow infections to run amok.

Initial blood work found hints of an infection, and the doctors initially suspected a bacterial skin infection (cellulitis) had taken hold in his nether region. So, they put him on some standard antibiotics for that. But his penis only got worse, redder, and more swollen. This prompted consultation with infectious disease doctors.

We all know streaming services’ usual tricks for making more money: get more subscribers, charge those subscribers more money, and sell ads. But science streaming service Curiosity Stream is taking a new route that could reshape how streaming companies, especially niche options , try to survive.

Discovery Channel founder John Hendricks launched Curiosity Stream in 2015. The streaming service costs $40 per year, and it doesn’t have commercials.

The streaming business has grown to also include the Curiosity Channel TV channel. CuriosityStream Inc. also makes money through original programming and its Curiosity University educational programming. The firm turned its first positive net income in its fiscal Q1 2025, after about a decade of business.

Over the past couple of weeks, friends and colleagues have made me aware of multiple ingeniously implemented, browser-based ways to play classic MS-DOS and Windows games with other people on basically any hardware.

The late 1990s and early 2000s were the peak of multiplayer gaming for me. It was the era of real-time strategy games and boomer shooters, and not only did I attend many LAN parties, but I also played online with friends.

That’s still possible today with several old-school games; there are Discord servers that arrange scheduled matches of Starsiege Tribes , for example. But oftentimes, it’s not exactly trivial to get those games running in modern Windows, and as in the old days, you might have some annoying network configuration work ahead of you—to say nothing of the fact that many folks who were on Windows back in those days are now on macOS or Linux instead.

Thousands of Asus routers have been hacked and are under the control of a suspected China-state group that has yet to reveal its intentions for the mass compromise, researchers said.

The hacking spree is either primarily or exclusively targeting seven models of Asus routers, all of which are no longer supported by the manufacturer, meaning they no longer receive security patches, researchers from SecurityScorecard said . So far, it’s unclear what the attackers do after gaining control of the devices. SecurityScorecard has named the operation WrtHug.

Staying off the radar

SecurityScorecard said it suspects the compromised devices are being used similarly to those found in ORB (operational relay box) networks, which hackers primarily use to conduct espionage to conceal their identity.
