  • Cancer Deaths Attributable to Alcohol Rose 58% Over the Last 33 Years
    by EditorDavid on 05/09/2026 at 4:50 pm

    CNN reports that alcohol "may play a greater role in death from numerous types of cancers in the United States than previously known, according to a new study." "While it's true that overall cancer mortality has declined, we found the percentage of cancer deaths proportionally attributable to alcohol rose over 58% in people 20 and older over the last 33 years," said the study's first author Dr. Chinmay Jani... It didn't take much alcohol to raise one's risk — about one standard drink a day, every day, Jani said. In the US, a standard drink is 12 ounces of regular beer, 5 ounces of wine or 1.5 ounces of 80-proof liquor... Alcohol is ethanol or ethyl alcohol, which is broken down by the liver into acetaldehyde, a "probable human carcinogen," the National Cancer Institute states on its website. While the liver will further break down acetaldehyde into a harmless molecule called acetate, the process isn't foolproof: acetaldehyde may damage DNA and interfere with DNA repair before conversion into acetate is complete. Alcohol also contributes to oxidative stress, which damages DNA, proteins and cell function and creates inflammation. Drinking alcohol also weakens the cells in the mouth and throat, making them more susceptible to carcinogens. That's even more likely to occur with smoking cigarettes, a major source of acetaldehyde. In addition, alcohol interferes with the break down and absorption of key nutrients thought to decrease cancer risk — vitamins A, C, D and E as well as folates in the vitamin B complex, according to the National Cancer Institute. The study, which was published Monday in The Lancet Regional Health — Americas journal, analyzed more than three decades of US data gathered for the Global Burden of Disease Study. The GBD study is a massive scientific effort to measure health, mortality and disabilities from hundreds of risk factors, diseases and conditions in more than 200 countries and territories. Between 1990 and 2023, the total number of yearly alcohol-linked cancer deaths more than doubled, rising from 11,361 to 23,126 in the US. Men and adults age 55 and older experienced the greatest impact; alcohol-related cancer mortality rate in older males climbed nearly 24% over the 33-year period. For men, liver cancer deaths showed the strongest link to alcohol, followed by esophageal and colorectal cancers. For women 55 and older, breast cancer was the top killer, followed by liver and colorectal cancers. Read more of this story at Slashdot.

  • Hundreds More Flock Cameras Removed in the US This Week. Flock Caught Repackaging Traffic Data
    by EditorDavid on 05/09/2026 at 12:20 pm

    Florida's Republican Governor Ron DeSantis said this week he's removing Flock cameras from state roadways. And according to a local news report, that led sheriff's departments in at least three other Florida counties to also "announce they're ending their own license plate reader programs." The same week in Texas, the Dallas Police Department announced it's also shutting down over 300 more Flock cameras, acccording to The Hill, after Republican Governor Greg Abbott ordered state agencies to halt funding. And in Wisconsin "at least a dozen" law enforcement agencies announced they'd suspend use of Flock's cameras, reports the Milwaukee Journal-Sentinel, joining Wisconsin cities like Appleton, Oshkosh and Kenosha that also cancelled their Flock contracts. But this week's cancellations had a new reason: Officials said it was revealed [Flock] had been collecting five years of traffic data, which had been stripped of identifying information, from cities' Flock cameras, and repackaging that as a traffic analytics product to sell to cities. All said they supported the effectiveness of the technology in investigations, but cited losing faith in the company's trustworthiness. "This is not what we agreed to, and it is not what the public was led to believe," said Racine County Sheriff Christopher Schmaling in a news release announcing the removal of Flock cameras operated by the agency. "The Sheriff's Office will not participate in a system that appears to use public safety as a justification for mass surveillance and the collection and monetization of information about innocent people...." [Racine County] officials were told the company believed if it stripped the data of any identifiable nature, it was then considered to be the company's property and no longer the city's. [Lt. Michael Luell, the sheriff's public information officer] said the sheriff's office has outside attorneys, along with the county's attorneys, investigating the company's move. "Our contract, from my reading of it is, it stated they agreed not to distribute or sell our data," Luell told the Journal Sentinel. "But they had this legal theory."

  • OpenAI Agents Hijacked a German Wiki to Discuss Ways to Escape Their Sandbox
    by EditorDavid on 05/09/2026 at 7:50 am

    Citing researchers published Friday, Ars Technica writes that AI agents "posted 18,000 messages to a public wiki that discussed ways for other agents to bypass security sandbox restrictions." Reuters attributes the discussion to "a swarm of rogue OpenAI agents" that "hijacked a German website this spring and transformed it into a bulletin board for other AI agents, according to new research published Friday and two people familiar with the matter." OpenAI officials learned of the incident weeks ago but kept it under wraps as executives grappled with the fallout from the July breach of the open source repository Hugging Face, the people said. The episode, which began in May and has not previously been reported, underscores growing tension within the AI industry. Companies are racing to build increasingly autonomous agents capable of carrying out complex, valuable tasks, yet evidence is mounting that those systems may also learn to bend rules, exploit loopholes and coordinate with one another in ways developers neither anticipated nor intended. During the Hugging Face breach, OpenAI agents autonomously plotted a digital heist that went undetected for more than a week, intensifying concerns OpenAI is sacrificing safety to push the AI frontier. Its failure to disclose the May incident may revive questions about its oversight... The German incident reflects a broader pattern of AI activity that some OpenAI investigators wanted to scrutinize more closely. But efforts to widen the probe met resistance from others inside OpenAI, including legal advisers, according to four people familiar with the matter. "Claims that our legal team discouraged investigation of the incident are false," the OpenAI spokesperson said... The researchers said public server logs indicated much of the activity originated from Microsoft Azure infrastructure, which OpenAI sometimes uses. They also observed repeated visits to the site by OpenAI employees after the episode, a pattern they said strongly suggested the agents and the company were linked. Messages reviewed by the researchers showed agents plotting ways to evade detection, use tools such as Tor and preserve communications even after they had been shut down. When the site's moderator began deleting pages in June, the agents responded by creating backup pages to dodge the cleanup. Reuters got this reaction from Maurice Chiodo, an academic at Cambridge University's Centre for the Study of Existential Risk. "The episode, he said, should reinforce growing concerns that the greatest threat from advanced AI may not be a single superintelligent system, but 'vast colluding swarms of semi-intelligent AI.'"

  • 'Coyote vs. Acme' Beats Ridley Scott's Newest Movie
    by EditorDavid on 05/09/2026 at 3:20 am

    Inverse shares a movie success story from last weekend: Coyote vs. Acme debuted to $15.9 million at the box office, beating out iconic director Ridley Scott's latest sci-fi adventure, The Dog Stars. This success has only continued since, and the worldwide box office currently sits above $22 million. Strong reviews and word-of-mouth are sure to keep viewers coming in, especially during the holiday weekend. What's impressive is Coyote vs. Acme had a limited marketing campaign that includes viral stunts. They photographed the movie's world premiere with a vintage Tasmanian Devil polaroid camera, and launched a phone number for the law firm suing Acme. ("If you've been injured by an enormous rubber band, press 7. If you've been injured by painted train tunnel that suddenly sprang to life, press 8...") And Cartoon Brew reports that Wednesday "the famously silent Looney Tunes star participated in an AMA on Reddit's r/movies, answering questions about his career, his relationship with the Road Runner, and the Warner Bros. executive who nearly prevented audiences from seeing his latest movie." In keeping with tradition, Wile E. delivered his responses through images of himself holding signs. The format produced several interesting and occasionally thought-provoking exchanges, but one obvious highlight came when a user asked: "Rumor has it that David Zaslav was paid off by ACME to cancel your film; what is your opinion on this?" Wile E.'s response was an image of the coyote glaring at the camera while holding a sign that read, "It's a limited number of signs," pulled from a scene in the film when Mr. Coyote first meets his eventual attorney Kevin Avery, played by Will Forte. Meanwhile, Boing Boing cites local news reports that a Southern California bird watcher Alexander DeBarros has actually captured a photo of a coyote holding a roadrunner bird in its mouth: In an incredible coincidence that is a movie publicist's dream, he snapped the rare, possibly unprecedented, photo on the opening weekend of the movie Acme vs. Coyote... In an even more incredible coincidence, DeBarros's father, Brian Mainolfi, is an animator whose first job in the field was working for Chuck Jones, the creator and director of the Roadrunner cartoon series. Cartoon Brew notes a Reddit user specifically asked the Coyote for his reaction to the news. Wile E. responded with some unexpectedly healthy advice: "We cannot judge our worth on the work of others." Aftermath calls the movie "a well made, deeply funny movie that pays a deep respect to the Looney Tunes in a way that Warner Brothers currently seems uninterested in doing."

  • Auto Companies Call For Ban On Chinese-Made Cars
    by BeauHD on 04/09/2026 at 3:00 pm

    An anonymous reader quotes a report from The Hill: A group representing American automakers sent a letter (PDF) Thursday to congressional leaders asking for a "permanent ban" on Chinese-made cars in the U.S. John Bozzella, the Alliance for Automotive Innovation's CEO and president, described in the letter China's manufacturing industry as "rooted in a well-documented pattern of unfair trade, subsidies, intellectual property theft and surveillance." Bozzella addressed his request to Senate Majority Leader John Thune (R-S.D.), Senate Minority Leader Chuck Schumer (D-N.Y.), Speaker Mike Johnson (R-La.) and House Minority Leader Hakeem Jeffries (D-N.Y.) -- urging them to back a "permanent ban on the sale, import and manufacture of Chinese connected vehicles," before the 119th Congress concludes in January. "Right now, Chinese automakers are dumping subsidized vehicles with connected software and hardware around the world," Bozzella wrote, adding that China "is capturing market share" in Europe, Australia, Southeast Asia, Mexico and South America. "This hasn't happened inside the U.S. yet, but given the scale and urgency of this threat, we urge you to enact a Chinese vehicle, software and hardware ban before adjourning this year and make this policy the law of the land," he added. The Alliance for Automotive Innovation, a trade organization representing car manufacturers, represents the "entire" U.S. auto industry, per its website. Bipartisan bills in the Senate and House would bar automakers with more than 15% Chinese ownership from selling vehicles in the U.S. "Enacting a permanent ban on Chinese vehicles and high-risk hardware and software in the 119th Congress will send a clear and bipartisan message that China's strategy to dominate global automotive manufacturing will be met with a national security policy response from the American government," wrote Bozzella.

  • Genetically Modified Pig Kidney Keeps Man Alive For Record Nine Months
    by BeauHD on 04/09/2026 at 11:00 am

    A genetically modified pig kidney kept a 66-year-old man off dialysis for a record nine months, marking the longest survival yet for a pig kidney transplanted into a living person and the first time such an organ successfully served as a bridge to a later human transplant. The Guardian reports: Tim Andrews was seriously ill with end-stage kidney disease caused by type 2 diabetes and had only a 9% chance of receiving a human kidney within five years, against a more than 40% risk of dying or being removed from the waiting list. Kidney transplantation provides the best survival and quality of life for patients with end-stage kidney disease, but global demand for human organs far exceeds supply. Surgeons in the US successfully transplanted a kidney from Wilma, a Yucatan miniature pig, into Andrews, after genetically engineering it to be compatible with his immune system. The kidney kept Andrews free of dialysis for a record nine months, the longest period ever recorded, before it began failing and he received one from a dead human donor. It was also the first time a pig's kidney had been used as a temporary "bridge" to a human transplant. The breakthrough has been detailed in the journal Lancet. Read more of this story at Slashdot.
