When last we looked at the state of the US grid, the ongoing explosion in solar energy had turned it into a major contributor, but one that still lagged well behind fossil-fuel-powered generation. So it was a bit of a surprise when preliminary data suggested that May 2026 saw solar power pass coal-fired generation for the first time in the US. Now, with the official release of April grid data by the Energy Information Administration, we can see that production of solar electricity had passed coal a month earlier—with a bit of a caveat.
The caveat being that a substantial chunk of that solar production never reached the grid, since it's produced by rooftop installations and used in the building they sit atop.
The situation heading into April/May was pretty simple. After a brief resurgence last year, coal use resumed its decline, despite repeated government attempts to prop it up. Meanwhile, solar continued its rapid growth, driven by its position as the cheapest way to add generating capacity in most of the US. But this growth started from a small base, and the early months of the year are marked by seasonally low solar production. As a result, growth above 20 percent year over year still left solar providing only 6 percent of the power on the US grid, a sharp contrast to coal's 16 percent.

The Fourth Amendment protects a user’s “location history,” the Supreme Court ruled Monday.
The same logic already applied to a cellphone’s tracking, and the high court found “no good reason exists to reach a different result for Location History” collected by third parties like Google.
Split 6-3, the majority agreed that the government needs a warrant and must show reasonable cause to turn a phone's location-tracking services into a government surveillance tool.

Sony recently informed its PlayStation customers in the United Kingdom that they will no longer be able to watch previously purchased movies and shows from production and distribution company StudioCanal. As of September 1, affected customers will no longer be able to stream 551 titles from the PlayStation Store.
In a legal notice first spotted by gaming news outlet PlayStation LifeStyle, Sony said that affected customers will lose the ability to stream titles including Outrage: Way of the Yakuza, Paddington, Paddington 2, Pan’s Labyrinth, Rambo 3, Terminator 2: Judgment Day, and The Boy in the Striped Pajamas “due to our content licensing agreements.” As of September, Sony will remove any affected titles that UK users bought from their PlayStation library, per the notice.
It’s possible that Sony may still make a deal with StudioCanal by September 1, or even after, that would allow users to keep watching the content they bought. This happened in 2023, when Sony said it would have to pull 1,318 seasons of Discovery shows from customers’ libraries. A few weeks after its announcement, Sony said that it would not pull the content because it had updated its licensing arrangements with Discovery.

The ban on ozone-depleting substances that successfully reversed the growth of the hole in the ozone layer isn’t seen as a missed opportunity. On the contrary, the quick global response is one of the best cases of common-sense environmental action. But what if it could have been done even earlier?
The fact that chlorofluorocarbons (CFCs)—chemicals once common in aerosol cans and refrigerant loops—could destroy ozone in the atmosphere was discovered in 1974. Within just a few years, bans on CFCs began to roll out based on the projected consequences. The seasonal ozone “hole” discovered over Antarctica in 1985 pushed things along even faster, and in 1987 an international agreement was signed to phase out CFCs everywhere.
A new study led by Jian Guan at MIT asks an interesting what-if question: Would it have been possible to detect this problem even sooner with today’s scientific tools?

Europe's push to rein in Big Tech is ramping up, with the European Commission planning to announce new regulations for Google next month. The rules could see Google forced to play nicer with its EU competitors, but the company has some concerns. Google is framing this not as a manifestation of its anticompetitive bent, but as genuine concern for user privacy.
Heather Adkins, Google’s VP of security engineering, told Wired that the EU's proposals could lead to serious security and privacy issues. The potential changes come in two forms. First, regulators want Gemini dethroned as the sole integrated AI service on Android. This would mean letting users integrate other AI models and give them Gemini-like system access. Separately, the EU wants Google to share anonymized search data with other companies.
"If implemented as described today, I think within a short period of time on Android, we’d see a significant increase in fraud in the EU," said Adkins, who noted these events could happen within weeks of pushing through the changes.

A short time back, we covered an announcement by Amazon that it would be hosting a useful quantum computer from its partner QuEra as soon as sometime in 2028. The system promised some eye-popping numbers compared to anything on the market today: over 10,000 individual qubits, each with an error rate low enough that the system could support hundreds of error-corrected logical qubits. But QuEra has to get there from its current hardware, which sits at 260 qubits that are relatively error-prone.
Those details about how it was going to get there were left for last Wednesday, when QuEra announced its roadmap. But the announcement only accentuated the gap: There will be no new hardware releases between now and the useful machine, and QuEra is promising to deliver an even more powerful machine just one year later.
"The company made a strategic decision not to sell NISQ [noisy intermediate scale quantum] systems anymore," QuEra's Yuval Borger told Ars. The two systems it had previously made available have similar capabilities, with about 250 hardware qubits and an appreciable error rate—enough to test some error correction codes, but not sufficient for using logical qubits in applications.
