Could Heart Attacks Be Triggered By Infections?

✇Slashdot

13 septembre 2025 à 20:34
Finland's second-largest university has announced new research suggesting that heart attacks could be an infectious disease. [T]he research found that, in coronary artery disease, atherosclerotic plaques containing cholesterol may harbor a gelatinous, asymptomatic biofilm formed by bacteria over years or even decades. Dormant bacteria within the biofilm remain shielded from both the patient's immune system and antibiotics because they cannot penetrate the biofilm matrix. A viral infection or another external trigger may activate the biofilm, leading to the proliferation of bacteria and an inflammatory response. The inflammation can cause a rupture in the fibrous cap of the plaque, resulting in thrombus [blood clot] formation and ultimately myocardial infarction... "Bacterial involvement in coronary artery disease has long been suspected, but direct and convincing evidence has been lacking," explains professor Pekka Karhunen [who led the study with researchers from the UK and Finland]. "Our study demonstrated the presence of genetic material — DNA — from several oral bacteria inside atherosclerotic plaques." The findings were validated by developing an antibody targeted at the discovered bacteria, which unexpectedly revealed biofilm structures in arterial tissue. Bacteria released from the biofilm were observed in cases of myocardial infarction. The body's immune system had responded to these bacteria, triggering inflammation which ruptured the cholesterol-laden plaque. The observations pave the way for the development of novel diagnostic and therapeutic strategies for myocardial infarction. Furthermore, they advance the possibility of preventing coronary artery disease and myocardial infarction by vaccination. "The research is part of an extensive EU-funded cardiovascular research project involving 11 countries..."

Myanmar's 'Cyber-Slavery Compounds' May Hold 100,000 Trafficked People

It was "little more than empty fields" five years ago — but it's now "a vast, heavily guarded complex stretching for 210 hectares (520 acres)," reports the Guardian, "the frontline of a multibillion-dollar criminal fraud industry fuelled by human trafficking and brutal violence." Myanmar, Cambodia and Laos have in recent years become havens for transnational crime syndicates running scam centres such as KK Park, which use enslaved workers to run complex online fraud and scamming schemes that generate huge profits. There have been some attempts to crack down on the centres and rescue the workers, who can be subjected to torture and trapped inside. But drone images and new research shared exclusively with the Guardian reveal that the number of such centres operating along the Thai-Myanmar border has more than doubled since Myanmar's military seized power in 2021, with construction continuing to this day. Data from the Australian Strategic Policy Institute (Aspi), a defence thinktank in Canberra, shows that the number of Myanmar scam centres on the Thai border has increased from 11 to 27, and they have expanded in size by an average of 5.5 hectares a month. Drone images and photographs of KK Park and other Myanmar scam centres, Tai Chang and Shwe Kokko, taken by the Guardian in August show new features and active building work... Myanmar's military junta has allowed the spread of scam centres inside the country as these criminal enterprises have become an essential part of the country's conflict economy since the coup, helping it rise to the top of the global list of countries harbouring organised crime. According to Aspi's analysis, Myanmar's military, which has lost huge swathes of territory since the coup and is struggling to retain its grip on power, cannot take meaningful measures against the scam compounds without endangering its precarious relations with the crucial armed militias who are profiting from them. While 7,000 people were freed from the compounds earlier this year, "Thai police estimated earlier this year that as many as 100,000 people were held inside Myanmar scam centres," the article notes. Elsewhere the Guardian reports that "The centres are run by Chinese criminal gangs," and describes people who unwittingly came to Thailand for customer service jobs, only to be trafficked to Myanmar's guarded "cyberslavery compounds" and "forced to send thousands of messages from fake social-media profiles, posing as a rich American investor to swindle US real estate agents into cryptocurrency scams." Since 2020, south-east Asia's cyber-slavery industry has entrapped hundreds of thousands of people and forced them to perform "pig butchering" — the brutal term for building trust with a fraud target before scamming them. At first, the industry mostly captured Chinese and Taiwanese people, then it moved on to south-east Asians and Indians — and now Africans. Criminal syndicates have been shifting towards scamming victims in the US and Europe after Chinese efforts to prevent its citizens being targeted, experts told the Guardian. That has led some trafficking networks to seek recruits with English-language and tech skills — including east Africans, thousands of whom are now estimated to be trapped inside south-east Asian compounds, says Benedikt Hofmann, the UN Office on Drugs and Crime's representative for south-east Asia and the Pacific.

UAE Lab Releases Open-Source Model to Rival China's DeepSeek

"The United Arab Emirates wants to compete with the U.S. and China in AI," writes Gizmodo, "and a new open source model may be its strongest contender yet. "An Emirati AI lab called the Institute of Foundation Models (IFM) released K2 Think on Tuesday, a model that researchers say rivals OpenAI's ChatGPT and China's DeepSeek in standard benchmark tests." "With just 32 billion parameters, it outperforms flagship reasoning models that are 20x larger," the lab wrote in a press release on Tuesday. DeepSeek's R1 has 671 billion parameters, though only 37 billion are active. Meta's latest Llama 4 models range from 17 billion to 288 billion active parameters. OpenAI doesn't share parameter information. OpenAI doesn't share parameter information. Researchers also claim that K2 Think leads "all open-source models in math performance" across several benchmarks. The model is intended to be more focused on math, coding, and scientific research than most other AI chatbots. The Emirati lab's selling point for the model is similar to DeepSeek's strategy that disrupted the AI market earlier this year: optimized efficiency that will have better or the same computing power at a lower cost... The lab is also aiming to be transparent in everything, "open-sourcing not just models but entire development processes" that provide "researchers with complete materials including training code, datasets, and model checkpoints," IFM said in a press release from May. The UAE and other Arab countries are investing in AI to try reducing their economic dependence on fossil fuels, the article points out.

A Single Exercise Session May Slow Cancer Cell Growth, Study Finds

✇Slashdot

13 septembre 2025 à 17:34
The Washington Post notes that past research "indicates that exercise helps some cancer survivors avoid recurrence of their disease." But a new study "offers an explanation of how, showing that exercise changes the inner workings of our muscles and cells, although more study is still needed..." The study, published last month, involved 32 women who'd survived breast cancer. After a single session of interval training or weightlifting, their blood contained higher levels of certain molecules, and those factors helped put the brakes on laboratory-grown breast cancer cells. "Our work shows that exercise can directly influence cancer biology, suppressing tumor growth through powerful molecular signals," said Robert Newton, the deputy director of the Exercise Medicine Research Institute at Edith Cowan University in Perth, Australia, and senior author of the new study. His group's experiment adds to mounting evidence that exercise upends the risks of not only developing but also surviving cancer... Scientists know contracting muscles release a slew of hormones and biochemicals, known as myokines, into our bloodstreams and have long suspected these myokines fight cancer. In some past studies with mice and healthy people, blood drawn after exercise and added to live cancer cells killed or suppressed the cancer's growth... [The new study tested cancer cells in high-tech petri dishes with blood drawn from cancer survivors.] Drenched in plasma from either the interval trainers or the lifters, many cancer cells quit growing. Quite a few died. (The blood drawn before exercise had no effects.) The cancer-fighting impacts were greatest with the blood drawn after interval training. Why? Additional testing showed this blood contained the highest concentrations of certain, beneficial myokines, especially IL-6, a protein that affects immune responses and inflammation... What these results mean, Newton said, is that "exercise doesn't just improve fitness and well-being" in people who've had cancer. "It also orchestrates a complex biological response that includes direct anticancer signals from muscles..." Questions remain, of course. Can any type of exercise fight cancer? Newton and other researchers have doubts. The exercise in this study was strenuous, by design. "Earlier studies suggested that the stronger the exercise stimulus, the greater the release of anticancer myokines," Newton said... Even the weight training in this study was less potent than the intense intervals. But Newton believes weight training remains key to cancer fighting. "People with cancer who increase their muscle mass through resistance training also experience greater rises in circulating myokines," he said. More muscle means more myokines.

The Software Engineers Paid To Fix Vibe Coded Messes

13 septembre 2025 à 16:34
"Freelance developers and entire companies are making a business out of fixing shoddy vibe coded software," writes 404 Media, interviewing one of the "dozens of people on Fiverr... now offering services specifically catering to people with shoddy vibe coded projects." Hamid Siddiqi, who offers to "review, fix your vibe code" on Fiverr, told the 404 Media that "Currently, I work with around 15-20 clients regularly, with additional one-off projects throughout the year. ("Siddiqi said common issues he fixes in vibe coded projects include inconsistent UI/UX design in AI-generated frontends, poorly optimized code that impacts performance, misaligned branding elements, and features that function but feel clunky or unintuitive," as well as work o color schemes, animations, and layouts.) And others coders are also pursuing the "vibe coded mess" market: Swatantra Sohni, who started VibeCodeFixers.com, a site for people with vibe coded projects who need help from experienced developers to fix or finish their projects, says that almost 300 experienced developers have posted their profiles to the site. He said so far VibeCodeFixers.com has only connected between 30-40 vibe code projects with fixers, but that he hasn't done anything to promote the service and at the moment is focused on adding as many software developers to the platform as possible... "Most of these vibe coders, either they are product managers or they are sales guys, or they are small business owners, and they think that they can build something," Sohni told me. "So for them it's more for prototyping..." Another big issue Sohni identified is "credit burn," meaning the money vibe coders waste on AI usage fees in the final 10-20 percent stage of developing the app, when adding new features breaks existing features. Sohni told me he thinks vibe coding is not going anywhere, but neither are human developers. "I feel like the role [of human developers] would be slightly limited, but we will still need humans to keep this AI on the leash," he said. The article also notes that established software development companies like Ulam Labs, now say "we clean up after vibe coding. Literally." "Built something fast? Now it's time to make it solid," Ulam Labs pitches on its site," suggesting that for their potential customers "the tech debt is holding you back: no tests, shaky architecture, CI/CD is a dream, and every change feels like defusing a bomb. That's where we come in."

Megaupload Founder Kim Dotcom Loses Latest Bid to Avoid US Extradition

In 2015 Kim Dotcom answered questions from Slashdot's readers. Now CBS News reports on "the latest chapter in a protracted 13-year battle by the U.S. government" to extradite Finnish-German millionaire Kim Dotcom from New Zealand: A New Zealand court has rejected the latest bid by internet entrepreneur Kim Dotcom to halt his deportation to the U.S. on charges related to his file-sharing website Megaupload. Dotcom had asked the High Court to review the legality of an official's August 2024 decision that he should be surrendered to the U.S. to face trial on charges of copyright infringement, money laundering and racketeering... The Megaupload founder had applied for what in New Zealand is called a judicial review, in which a judge is asked to evaluate whether an official's decision was lawful. A judge on Wednesday dismissed Dotcom's arguments that the decision to deport him was politically motivated and that he would face grossly disproportionate treatment in the U.S... New Zealand's government hasn't disclosed what will happen next in the extradition process or divulged an expected timeline for Dotcom to be surrendered to the United States Dotcom "has been free on bail in New Zealand since February 2012," the article points out — and "One of his lawyers, Ron Mansfield, told Radio New Zealand that Dotcom's team had 'much fight left in us as we seek to secure a fair outcome,' but he didn't elaborate..." The article notes that the latest decision "could be challenged in the Court of Appeal, where a deadline for filing is October 8."

ScienceDaily reports: Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns for both consumers and brewers... [PFAS] have been found in surface water, groundwater and municipal water supplies across the U.S. and the world. Although breweries typically have water filtration and treatment systems, they are not designed to remove PFAS... [T]he researchers call for greater awareness among brewers, consumers and regulators to limit overall PFAS exposure. These results also highlight the possible need for water treatment upgrades at brewing facilities as PFAS regulations in drinking water change or updates to municipal water system treatment are implemented. "I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours," research lead Jennifer Hoponick Redmon said in a May announcement about their research.

Pilot Union Urges FAA To Reject Rainmaker's Drone Cloud-Seeding Plan

✇Slashdot
Par :BeauHD
13 septembre 2025 à 13:00
An anonymous reader quotes a report from TechCrunch: Rainmaker Technology's bid to deploy cloud-seeding flares on small drones is being met by resistance from the airline pilots union, which has urged the Federal Aviation Administration to consider denying the startup's request unless it meets stricter safety guidelines. The FAA's decision will signal how the regulator views weather modification by unmanned aerial systems going forward. Rainmaker's bet on small drones hangs in the balance. The Air Line Pilots Association (ALPA) told the FAA that Rainmaker's petition "fails to demonstrate an equivalent level of safety" and poses "an extreme safety risk." Rainmaker is seeking an exemption from rules that bar small drones from carrying hazardous materials. The startup filed in July, and the FAA has yet to rule. Instead, it issued a follow-up request for information, pressing for specifics on operations and safety. In its filing, Rainmaker proposed using two flare types, one "burn-in-place" and the other ejectable, on its Elijah quadcopter, to disperse particles that stimulate precipitation. Elijah has a maximum altitude of 15,000 feet MSL (measured from sea level), which sits inside controlled airspace where commercial airliners routinely fly. Drones need permission from Air Traffic Control to fly inside this bubble. Rainmaker's petition says it will operate in Class G (uncontrolled) airspace unless otherwise authorized. ALPA notes the filing doesn't clearly state where flights would occur or what altitudes would be used. Rainmaker and ALPA did not reply to TechCrunch's requests for comment. The union also objects to the flares themselves, citing concerns about foreign object debris and fire safety. ALPA points out that the petition does not include trajectory modeling of the ejectable casings or analysis on the environmental impacts of chemical agents. However, Rainmaker says the flights will occur over rural areas and over properties owned by private landlords "with whom Rainmaker has developed close working relationships." [...] What happens next hinges on whether the FAA thinks those mitigations are sufficient. However it's decided, the agency's response will likely set the tone for novel cloud-seeding approaches.
