Next Space Force chief throws cold water on the idea of space privateers

fivenewscrypto    juillet 23, 2026   

In the early years of the United States, when the nascent US Navy was still getting its sea legs, several presidents used privateers to capture or destroy enemy warships when armed naval vessels were unable to do so.

President John Adams was one of the most vigorous proponents of commissioning private vessels for national ends. His administration issued letters of marque and reprisal during the so-called "Quasi-War" with France in the final years of the 18th century. These letters created the legal distinction between privateering and piracy.

One of the letters signed by Adams, dated November 1799, authorized the use of a merchant ship to "subdue, seize, and take any armed French vessel" found near US coastal waters of "elsewhere on the high seas." France also routinely used privateers against US shipping at the time.

OpenAI says its AI agent broke out of testing sandbox to hack Hugging Face

OpenAI says its AI agent broke out of testing sandbox to hack Hugging Face

fivenewscrypto    juillet 23, 2026   

OpenAI says an agent powered by its LLM models escaped its sandboxed testing environment to infiltrate Hugging Face's servers as part of an overzealous attempt to obtain solutions to a benchmark test. The company says it considers the unintended infiltration an "an unprecedented cyber incident" and is working with Hugging Face on new protections to prevent a recurrence.

Hugging Face disclosed an intrusion last week that it said involved "unauthorized access to a limited set of internal datasets and to several credentials used by our services." The AI data clearinghouse said it used its own LLM-driven analysis to identify "a swarm of tens of thousands of automated actions" from an "autonomous agent framework." That agentic swarm exploited a flaw in Hugging Face's data-processing pipeline to gain the ability to run code as a processing worker, eventually escalating to high-level access to the company's cloud and server clusters.

At the time, Hugging Face said the LLM being used in the attack was "still not known." But OpenAI took responsibility for the intrusion Tuesday evening, saying it came about during an internal test involving the recently released GPT-5.6 Sol and "an even more capable pre-release model." The models were being tested against the ExploitGym benchmark, an independent testing suite based on hundreds of real-world security vulnerabilities.

Ukrainian drones deliver robots directly into battle by sea and air

Ukrainian drones deliver robots directly into battle by sea and air

fivenewscrypto    juillet 23, 2026   

In the latest twist on battlefield innovations, Ukraine has used both flying drone carriers and drone boats to send ground robots armed with weapons or explosives into battle.

The drone-assisted deployments have enabled slower wheeled robots to bypass tough terrain and Russian defenses, and to carry out an unusual robotic amphibious assault on a contested position. Such tactics also showcase the Ukrainian military’s ongoing experimentation with using drones and robots to offset a Russian military advantage in manpower while also sparing Ukrainian soldiers from making dangerous assaults.

On July 19, a Russian military Telegram channel posted a video showing a Ukrainian hexacopter drone carrying a ground robot suspended below by a cable, according to the Ukrainian government-run news platform United24. The Russian Telegram channel described the Ukrainian heavy bomber drone as deploying a four-wheeled ARK-1 robot armed with explosive anti-tank mines on the ground where it continued toward Russian military positions—and apparently generated plenty of outraged comments from pro-Kremlin social media users.

Confusion swirls on source of diarrhea outbreak, but it’s still Taylor Farms

Confusion swirls on source of diarrhea outbreak, but it’s still Taylor Farms

fivenewscrypto    juillet 23, 2026   

Federal officials on Monday reaffirmed that iceberg lettuce from Taylor Farms still appears to be the source of Cyclospora, the microscopic parasite behind a multi-state surge in explosive diarrhea cases.

The assertion was intended to clear up confusion that began swirling over the weekend around a false positive test from the Food and Drug Administration—which Taylor Farms celebrated, sparking confusion. Still, many details of the outbreak remain murky, largely due to the vague recall information Taylor Farms has publicly provided.

On Friday, the FDA, along with the Centers for Disease Control and Prevention, announced that the FDA's traceback investigations for the outbreak converged on Taylor Farms. Traceback investigations work by tracking backward from sick people and the foods they ate to where those foods came from through the supply chain, down to individual farms or production facilities. When the FDA said their investigation converged on Taylor Farms, the agency means that, over and over again, tracebacks led them to shredded iceberg lettuce grown in Central Mexico and supplied by Taylor Farms—which also goes by Taylor Fresh Foods.

Nintendo says users voluntarily paid higher prices, have no right to tariff refunds

Nintendo says users voluntarily paid higher prices, have no right to tariff refunds

fivenewscrypto    juillet 23, 2026   

Nintendo urged a court to dismiss a lawsuit demanding that it pass tariff refunds on to customers, saying that people who bought a Switch console or other products have no legal right to refunds that Nintendo is due to receive from the government.

Nintendo said in a motion to dismiss yesterday that plaintiffs are "ask[ing] this Court to invent a legal duty out of whole cloth to retroactively re-price completed sales simply because the legal landscape has changed." Nintendo said the plaintiffs "have no legal entitlement to the tariff refunds Nintendo stands to receive."

The lawsuit was filed in April by two customers who seek to represent a class of all US residents who bought Nintendo products from February 2025 to February 2026. California resident Gregory Hoffert and Washington resident Prashant Sharan filed the class action complaint in US District Court for the Western District of Washington, alleging unjust enrichment and a violation of the Washington Consumer Protection Act's prohibition on unfair or deceptive acts.

Let Tom Hiddleston be your guide to Pompeii's final day

Let Tom Hiddleston be your guide to Pompeii's final day

fivenewscrypto    juillet 22, 2026   

When Mount Vesuvius erupted in 79 CE, it spewed molten rock, pumice, and hot ash over the cities of Pompeii and Herculaneum, killing thousands of people. It's one of the most famous natural disasters in human history, so naturally there have been countless documentaries about Pompeii (and at least one popular song). But only one features actor Tom Hiddleston taking on the role of a "time detective" to bring the people of Pompeii to vivid life. That would be National Geographic's new three-part docuseries, Pompeii: Out of Time.

The Marvel connection made Out of Time happen. Executive producer Kevin Wright was also a producer on the Disney+ series Loki, which included a scene where Hiddleston's Loki travels through time to visit Pompeii. Hiddleston also studied classics at Cambridge University and had visited the Pompeii archaeological site as a teenager, which the Marvel star attributes to indirectly influencing his career path into acting.

"There is just a passion to the way Tom tells stories that's infectious," Wright told Ars. "We knew that if we could capture that and put it into [the series], it might interest people who wouldn't normally want to watch a documentary about Pompeii. "

Naked mole-rat queens use a chemical signal to suppress fertility in rivals

Naked mole-rat queens use a chemical signal to suppress fertility in rivals

fivenewscrypto    juillet 22, 2026   

Naked mole rats are weird. They spend their lives almost entirely underground, are largely insensitive to some kinds of pain, can persist without oxygen for a long time, rarely develop cancer, and can live past 30 years, which is decades longer than similarly sized rodents. They are also eusocial, like ants, bees, or termites—in a colony that can hold more than a hundred animals, only one female, the queen, breeds.

We didn’t know how exactly naked mole-rat queens stop other females from breeding. For a long time, our leading hypothesis was bullying and violence, but that may be a bit impractical, given their kingdoms are vast networks of tunnels that can stretch for up to three kilometers. But now a team of Lewin Lab scientists at Max Delbrück Center for Molecular Medicine in Berlin discovered it’s actually just one part of a sophisticated olfactory signaling program.

Running on smell

"It's very clear that mole rats actually have quite big noses and smell a lot," says Gary Lewin, a neurobiologist at the Max Delbrück Center for Molecular Medicine and senior author of the study. Naked mole rats have around 1200 olfactory receptor genes, more than mice (which have roughly 1,000 of them) and way more than the few hundred in humans. They're also blind. "They have to be able to navigate and move around without vision, so smell is one of those things that’s enhanced," Lewin said.
