Against all odds, SpaceX finally tugs Starship into port after 24 days at sea

18 August 2026 at 19:01

SpaceX's most recent Starship test flight may have ended July 24, but its mission isn't over yet.

The spacecraft splashed down in the Indian Ocean intact after flying halfway around the world from SpaceX's launch base in South Texas. Engineers expected the ship's life to end with a fiery disintegration after toppling over, just as past Starships have done following splashdown.

Numerous onboard sensors and cameras, along with buoys and drones in position at the splashdown zone, have provided important data for SpaceX to assess the performance of the ship's heat shield after each test flight, so officials accepted the post-flight conflagrations. That day, Starship tipped over and remained intact, surprising just about everyone.

Disney sues FCC and its chair, escalating fight against Trump's chief censor

18 August 2026 at 18:11

Disney today sued the Federal Communications Commission and FCC Chairman Brendan Carr in a lawsuit that aims to stop what it called a "campaign of censorship" waged by the Trump administration against ABC.

Disney, ABC, and the eight broadcast stations they own filed a complaint in US District Court for the District of Columbia. They also submitted a motion for a temporary restraining order and preliminary injunction that would halt the FCC proceeding in which Carr is threatening to deny renewals of broadcast licenses held by ABC stations.

The lawsuit accused the FCC of violating the First Amendment by retaliating against the company's protected expression. "Again and again, the Administration has attacked ABC’s speech—the stories its journalists report and the viewpoints its network programs air," the lawsuit said. "Over time, those attacks have escalated into express demands that ABC be stripped of its broadcast licenses because of its speech."

Peacock raises prices by 18 percent after becoming profitable

18 August 2026 at 16:42

For the fourth time in four years, Peacock has raised its prices.

The Select plan, which has ads and doesn’t include sports, movies, or Peacock originals, went from $8/month to $9/month. The monthly fee for the standard ad plan (Premium) went from $11/month to $13/month, and the ad-free plan (Premium Plus) went from $17/month to $20/month. Annual pricing, as previously, offers 12 months for the price of 10 months.

Peacock’s previous price hike was in July 2025, when the middle tier (with ads) went from $8/month to $11/month, and the ad-free plan increased from $14 to $17. Peacock also raised prices in July 2024 and August 2023. NBCUniversal launched the service in 2020.

The United States is about to wake up to the threat from China's space program

18 August 2026 at 16:30

There are generally two schools of thought in the Western space community when it comes to the prospect of China landing humans on the Moon in the next few years and very possibly beating NASA and the United States in its efforts to return astronauts there.

Many people will ask what the big deal is. After all, NASA won the space race to the Moon nearly six decades ago, when Apollo 11 landed there. That it took so long for anyone else to follow speaks to the magnitude of the US achievement, they might say.

But others have a starkly different opinion. A dominant storyline of the 21st century has been the economic and geopolitical rise of China, and what was once a unipolar world now has two large nations vying for supremacy across a number of fronts. One is space. If China can land humans on the Moon before the United States returns, it will represent a huge geopolitical win. From a propaganda standpoint, it will allow China to declare that it has not just caught up to the United States but surpassed it as this century's superpower.

Fairphone's latest repairable phone is finally available in the US for $650

18 August 2026 at 16:05

As smartphone designs have become more refined, they've also become less repairable. Fairphone bucks that trend, offering devices that can be fully disassembled and serviced using a single screwdriver. But its devices were a pain to get in the US until now.

The Dutch company has launched the Fairphone Gen 6+ in the US, offering not only the phone but a full line of accessories and replacement parts so you can keep your phone running for years. And yes, the battery is removable.

Don't expect the Fairphone Gen 6+ to blow you away in the spec department—it focuses on being repairable and paying workers a fair wage. Half of the phone is made from recycled materials, and it has a microSD card slot. How retro.

Ford hopes this Hypercar will be its next Le Mans winner

18 August 2026 at 15:52

The car that Ford hopes will return it to overall victory at the 24 Hours of Le Mans made its unofficial debut this week. Ford sent us some pictures of the still-unnamed car conducting its first track test at the colorful Paul Ricard circuit in Provence, France, where drivers Matt Campbell and Logan Sargeant started the hard work of making the car both fast and reliable.

Ford already has four overall wins at Le Mans, owning the top spot four years in a row. But the last of these wins came in 1969, when a privately entered—and at that point outdated—GT40 managed to beat Porsche's still-untamed 917 on the German car's debut. The company returned to top-level endurance racing in 1982 with the C100 during the early days of the Group C regulations, but the car was uncompetitive and unreliable, and the program soon ended.

In 2016, 50 years on from its first win, a class win in the GTE-Pro category added some more silverware to the corporate display cabinet. Now, the soaring popularity of the Hypercar category in the World Endurance Championship and at Le Mans has tempted it back to the fastest class.

Teenage Sex and Death at Camp Miasma takes pains to deliver a slasher fan’s dream

18 August 2026 at 15:36

Here’s one for all the kids who were exposed to lurid slasher movies when they were way too young and it kinda messed them up… but they’re finally ready to laugh about it.

Jane Schoenbrun’s latest movie, Teenage Sex and Death at Camp Miasma, is shocking, emotional, provocative, numbing, warm, witty, and surreal. It’s a slasher nerd’s dream, with a David Fincher-esque attention to detail in the opening sequence, which was designed using insights gathered from horror convention-goers. Written to indulge superfans, the movie also makes sure to not lose the general audience. Just as the geeky navel-gazing threatens to become tedious, a joke or a wink keeps the audience laughing and focused on the fantastical story Schoenbrun actually wants to tell—which isn’t a genuine slasher at all.

The movie follows Kris (Hannah Einbinder), a queer film director tasked with creating a "woke" reboot of a politically incorrect sleepaway camp franchise in the vein of Friday the 13th. On her way to meet the reclusive final girl from the original Camp Miasma film—Billy Preston, portrayed deliciously by a junk food-obsessed Gillian Anderson—Kris fails to nail her pitch and instead gets yanked into a fantasy buried deep in her psyche while at the abandoned set where Billy now lives.

X-rays add new twist to narwhal's spiral tusk

Narwhals are toothed whales, renowned for their distinctive straight, spiraling tusks, which many people in medieval times believed were the horns of unicorns and thus held magical healing properties. That belief was debunked long ago, but the tusks remain popular souvenirs in Canada and Greenland. And they still hold a fascination for scientists keen to learn more about their unusual structure. A new paper published in the journal Nature Communications reports that rather than one left-oriented spiral, narwhal tusks also have a second internal spiral oriented in the opposite direction.

Inuit legend holds that a woman was dragged into the ocean by a harpoon rope after the weapon had hit a narwhal and was transformed into the animal herself. Her hair, which she'd worn in a twisted knot, became the spiral tusk. The tusk is actually a canine tooth in the left upper jaw of male narwhals, pushing through the lip when the males reach two or three years of age and growing to lengths as long as 1.5 to 2 meters (just under 5 feet to 9 feet 10 inches). Some males may develop two long spiral tusks or, in rare cases, none at all.

There's a general consensus that these tusks most likely evolved via sexual selection as a form of social status. They clearly aren't crucial for survival, since the females usually don't develop the tusk—and if they do, the tusks are much smaller with fewer spirals—and yet typically live longer than the males. But the precise function of the tusk is still a matter of considerable debate.

Microsoft Copilot reveals secret input that allowed it to be hacked

18 August 2026 at 13:00

It’s not every day that attackers can force a frontier AI model to cough up user passwords and other sensitive data without user confirmation. That’s exactly what researchers recently did to Microsoft 365 Copilot for enterprise. Even more unusual is the source they tapped to discover the critical vulnerability that made their exploit possible. Rather than employing reverse engineering or other traditional vulnerability-hunting methods, they asked Copilot. The LLM assistant readily complied.

Researchers at security firm Varonis knew they wanted to create an exploit that would exfiltrate user data when a user did nothing more than click on a link. Like most AI assistants today, Copilot steadfastly refused and made clear that sensitive prompts like that require explicit user consent in the form of a gesture, such as pressing a return key or other key. In response, the researchers peppered Copilot with questions about the guardrails that required user confirmation before the assistant could execute powerful commands.

Loose lips sink ships

The dialog was like a game of 20 questions. Each answer provided a new clue that divulged information about the complex safety mechanism. Why was auto-execution impossible, they asked. What URL structures and deep links were involved? What happens when a page is loaded with input already in the prompt field? Each answer provided a deeper view into the guardrail and its limits. Eventually, Copilot provided a stunning Microsoft trade secret—an undocumented prompt parameter that completely bypassed the requirement for user consent.

As temperatures get hotter, pesticides are more dangerous to farmworkers

For the nation’s 2.4 million farmworkers, climate change is poised to exacerbate the harms of pesticides, a growing body of research shows.

Heat stresses the body, making it more vulnerable to pesticides and other toxicants, and protective clothing worn in the heat only adds to this stress. Hotter temperatures can also lead to higher evaporation rates, increasing farmworkers’ exposure as more pesticides are applied to crops. And heat can boost rates of chemical transformation of pesticides into more toxic compounds.

“When it’s in the air, you are inhaling it through your nose. You are exposed to it through your other organs like skin. Your skin can absorb some of the pesticides [that are] in the air, and also when you’re sweating as part of doing your work you are increasing the pore size of your skin,” said Omanjana Goswami, a scientist in the food and environmental program at the Union for Concerned Scientists, an advocacy group. “It is awful. There is no other word for it.”

Theban tomb reveals how Egyptian burial trends evolved in time

18 August 2026 at 04:00

Egypt's Theban necropolis holds over 400 tombs, a rich resource for archaeologists eager to learn more about that region's ancient history. A new paper published in the journal Frontiers in Environmental Archaeology outlines how Egyptian burial trends likely changed over the course of centuries, shifting from individual burials in elaborate coffins to reusing earlier burial sites for later interments, resulting in greater density and the occasional superposition of bodies.

There has been prior research on the reuse of tombs in Thebes. This latest paper focused on a Theban tomb known as 209 in the western necropolis, dating back to the early 25th Dynasty (754–656 BCE) and ultimately abandoned in the Ptolemaic period (305–30 BCE). The original owner was likely a high official of Nubian origin named Nisemro. Over the centuries, the tomb was prone to repeated flash flooding due to its location within an active drainage channel of the Wadi Hatasun, so it's a complex site, archaeologically speaking.

That made it ideal for what the authors term an "integrated archaeothanatological approach," incorporating collected data on body position, coffin use, superpositions of remains, and stratigraphic relationships with osteological analysis in order to reconstruct the chronological sequence of the burials. They focused on a site known as Side Chamber 3, one of the main secondary areas of the tomb that was largely undisrupted.
