The death of the US government's Affordable Connectivity Program (ACP) is starting to result in disconnection of Internet service for Americans with low incomes. On Friday, Charter Communications reported a net loss of 154,000 Internet subscribers that it said was mostly driven by customers canceling after losing the federal discount. About 100,000 of those subscribers were reportedly getting the discount, which in some cases made Internet service free to the consumer.

The $30 monthly broadband discounts provided by the ACP ended in May after Congress failed to allocate more funding. The Biden administration requested $6 billion to fund the ACP through December 2024, but Republicans called the program "wasteful."

Republican lawmakers' main complaint was that most of the ACP money went to households that already had broadband before the subsidy was created. FCC Chairwoman Jessica Rosenworcel warned that killing the discounts would reduce Internet access, saying an FCC survey found that 77 percent of participating households would change their plan or drop Internet service entirely once the discounts expired.

Although driving is a privilege, some Americans treat it more like a right. This entitlement leads them to get upset with policy proposals that try to increase road safety by prioritizing vulnerable road users over the wants of drivers. But a new study suggests that a common complaint—taking away lanes from cars makes emergency response times go up—about traffic calming isn't actually true.

American roads aren't particularly safe, and while much of the blame of late has been directed at ever-bigger trucks and SUVs, the problem is more complex than just big cars. Like the built environment, standard American road design, with a pair of lanes going in either direction, makes it very easy to drive much faster than the speed limit, which is often over 25 mph.

This is where road diets come in—they're a relatively cheap and simple way to slow traffic and significantly cut the accident rate along a stretch of road. You take a four-lane (two-way road) and repaint it so there are now three lanes for cars: one in each direction, with a center lane in the middle for turning. The remaining space on either side becomes bike lanes (physically protected ones, please).

Sometime next year, SpaceX will begin returning its Dragon crew and cargo capsules to splashdowns in the Pacific Ocean and end recoveries of the spacecraft off the coast of Florida.

This will allow SpaceX to make changes to the way it brings Dragons back to Earth and eliminate the risk, however tiny, that a piece of debris from the ship's trunk section might fall on someone and cause damage, injury, or death.

"After five years of splashing down off the coast of Florida, we've decided to shift Dragon recovery operations back to the West Coast," said Sarah Walker, SpaceX's director of Dragon mission management.

California's "Safe and Secure Innovation for Frontier Artificial Intelligence Models Act" (a.k.a. SB-1047) has led to a flurry of headlines and debate concerning the overall "safety" of large artificial intelligence models. But critics are concerned that the bill's overblown focus on existential threats by future AI models could severely limit research and development for more prosaic, non-threatening AI uses today.

SB-1047, introduced by State Senator Scott Wiener, passed the California Senate in May with a 32-1 vote and seems well positioned for a final vote in the State Assembly in August. The text of the bill requires companies behind sufficiently large AI models (currently set at $100 million in training costs and the rough computing power implied by those costs today) to put testing procedures and systems in place to prevent and respond to "safety incidents."

The bill lays out a legalistic definition of those safety incidents that in turn focuses on defining a set of "critical harms" that an AI system might enable. That includes harms leading to "mass casualties or at least $500 million of damage," such as "the creation or use of chemical, biological, radiological, or nuclear weapon" (hello, Skynet?) or "precise instructions for conducting a cyberattack... on critical infrastructure." The bill also alludes to "other grave harms to public safety and security that are of comparable severity" to those laid out explicitly.

In the summers of 2018 and 2019, ecologist James Ryalls and his colleagues would go out to a field near Reading in southern England to stare at the insects buzzing around black mustard plants. Each time a bee, hoverfly, moth, butterfly, or other insect tried to get at the pollen or nectar in the small yellow flowers, they’d make a note.

It was part of an unusual experiment. Some patches of mustard plants were surrounded by pipes that released ozone and nitrogen oxides—polluting gases produced around power plants and conventional cars. Other plots had pipes releasing normal air.

The results startled the scientists. Plants smothered by pollutants were visited by up to 70 percent fewer insects overall, and their flowers received 90 percent fewer visits compared with those in unpolluted plots. The concentrations of pollutants were well below what US regulators consider safe. “We didn’t expect it to be quite as dramatic as that,” says study coauthor Robbie Girling, an entomologist at the University of Southern Queensland in Australia and a visiting professor at the University of Reading.

After SpaceX decided to launch orbital missions of its Starship rocket from Texas about five years ago, the company had to undergo a federal environmental review of the site to ensure it was safe to do so.

As a part of this multi-year process, the Federal Aviation Administration completed a Final Programmatic Environmental Assessment in June 2022. Following that review, SpaceX received approval to conduct up to five Starship launches from South Texas annually.

SpaceX has since launched Starship four times from its launch site in South Texas, known as Starbase, and is planning a fifth launch within the next two months. However, as it continues to test Starship and make plans for regular flights, SpaceX will need a higher flight rate. This is especially true as the company is unlikely to activate additional launch pads for Starship in Florida until at least 2026.

As was just rumored, the iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 developer betas are rolling out today, and they include the first opportunity to try out Apple Intelligence, the company's suite of generative AI features.

Initially announced for iOS 18, Apple Intelligence is expected to launch for the public this fall. Typically, Apple also releases a public beta (the developer one requires a developer account) for new OS updates, but it hasn't announced any specifics about that just yet.

Not all the Apple Intelligence features will be part of this beta. It will include writing tools, like the ability to rewrite, proofread, or summarize text throughout the OS in first-party and most third-party apps. It will also include new Siri improvements, such as moving seamlessly between voice and typing, the ability to follow when you stumble over your words, and maintaining context from one request to the next. (It will not, however, include ChatGPT integration; Apple says that's coming later.)
