'Dragonfly' Mission to Saturn's Moon Titan: Behind Schedule, Overbudget, Says NASA Inspector General

Slashdot.org - Sat, 09/13/2025 - 20:34
After its six-year journey to Saturn's moon Titan, Dragonfly's rotorcraft lander "will fly like a large drone," explains its web page, spending three years sampling multiple landing sites to characterize Titan's habitability and look for "precursors of the origin of life." "However, the project has undergone multiple replans impacting cost and schedule, resulting in a life-cycle cost increase of nearly $1 billion and over 2 years of delays," according to an announcement from NASA's Inspector General. From the Inspector General's report: The cost increase and schedule delay were largely the result of NASA directing [Johns Hopkins University] Applied Physics Laboratory to conduct four replans between June 2019 and July 2023 early in Dragonfly's development. Justifications for these replans included the COVID-19 pandemic, supply chain issues, changes to accommodate a heavy-lift launch vehicle, projected funding challenges, and inflation." But its higher-than-expected life-cycle cost over $3 billion "will continue to absorb an increasing proportion of the Planetary Science Division's total budget," meaning Dragonfly's increased cost (and "additional budget constraints") have "contributed to a gap of at least 12 years in New Frontiers [planetary science] mission launches, and will jeopardize future priorities outlined in the National Academies of Sciences, Engineering, and Medicine's (National Academies) decadal surveys." Yet a NASA press release notes the mission "has cleared several key design, development and testing milestones and remains on track toward launch in July 2028." Its software-defined radio has been completed, and the part of the spectrometer which analyzes Titan's chemical components for "potentially biologically relevant" compounds (as well as structural and thermal testing of the lander's insulation). "The mission is scheduled to launch in July 2028 on a SpaceX Falcon Heavy launch vehicle from NASA's Kennedy Space Center in Florida."

More Return-to-Office Crackdowns, with 61.7% of Employees Now in Office Full-Time

Slashdot.org - Sat, 09/13/2025 - 18:18
Paramount and Comcast's NBCUniversal are joining Microsoft in telling employees "they could face consequences if they don't return to the office more frequently," reports the Washington Post: NBCUniversal sent a memo to its employees telling them to return to the office four days a week starting in January [with the option to work remotely on Fridays]. Last week, Paramount told employees to return five days a week, with the first group starting in January. Both Paramount and NBCUniversal said they would offer severance packages to eligible employees who are unwilling or unable to make the switch... Companies have been cracking down on flexible work for the past several years, with Goldman Sachs being one of the first to implement a five-day office policy. Since then, others have joined in including Amazon, AT&T, JPMorgan Chase and the federal government... Overall, the number of people working full time in office hasn't changed much over the past couple of years. About 61.7 percent of salaried employees worked from an office full time in August, according to data from university researchers Jose Maria Barrero, Nicholas Bloom and Steven J. Davis, who are studying the matter. That is down one percentage point from August 2024, their research shows. During the same period, the amount of people working remotely dropped two percentage points and those working hybrid schedules increased three points. While most of the big office pushes are coming from some of the largest employers in the nation, the majority of companies in the United States aren't requiring full-time office work, said Brian Elliott [publisher of the Flex Index, which tracks flexible policies, and CEO]. And about half of U.S. workers are employed by smaller companies, he added. Some companies are capitalizing on the mandates, using flexible policies as a way to poach talent from their competitors, he said.... Some employers are using office mandates to purposely shed workers. An August report from the Federal Reserve Bank shows that "multiple districts reported reducing headcounts through attrition — encouraged, at times, by return-to-office policies and facilitated, at times, by greater automation, including new AI tools." Still, with fewer job openings in the market, some employees will have to comply with office mandates. Announcing their return-to-office mandates, employers gave the following reasons: "In-person collaboration is absolutely vital to building and strengthening our culture and driving the success of our business. Being together helps us innovate, solve problems, share ideas, create, challenge one another, and build the relationships that will make this company great." -- Paramount CEO David Ellison (in a memo to staff) "It has become increasingly clear that we are better when we are together. As we have all experienced, in-person work and collaboration spark innovation, promote creativity, and build stronger connections." -- Adam Miller, NBCUniversal chief operating officer (in a memo to staff)

Hollow Knight Sequel 'Silksong' Crashed Game Stores, as $20 Price Irks Competitors

Slashdot.org - Sat, 09/13/2025 - 17:18
Last week Steam and other major storefronts crashed, reports the Guardian, including Nintendo's eShop, PlayStation Store and Microsoft Store. They were all "unable to cope with the demand for Hollow Knight: Silksong, the long-awaited sequel to the critically acclaimed 2017 indie hit Hollow Knight." (which had sold 15 million copies): SilkSong's release triggered widespread outages, with thousands of users reporting issues trying to buy the game in the first few hours of its release. Many were unable to complete purchases, with error messages persisting for almost three hours after the launch... Despite the technical hiccups, within 30 minutes of going live Steam reported more than 100,000 active players, suggesting many had managed to secure their copies. Aftermath says the "bug-tastic" phenomenon displaced everything except Counter-Strike 2 and Dota 2 on Steam's list of most-played games. The Guardian notes that "At least seven other new games have delayed their launch in the past two weeks to avoid a clash..." "People have been spamming the chat and the comments of every single game showcase or news event with the words 'Where's Silksong?' for years," writes the Guardian's video games editor: I've never seen another indie game achieve this level of notoriety before it was even released... As VGC points out, Atari released a similar game on the same day as Silksong (Adventure of Samsara) and it had only 12 concurrent players on Steam. They add that "the hype is justified". Eurogame called Silksong "beautiful, thrilling and cruel." PC Game said Silksong "glows with a level of precision and imagination that's hard to find anywhere else" and "will beat you, burn you, rub your face in the dirt, and then dazzle you with another piece of a haunted clockwork world." But at least some of the demand also came from the game's low price of $20 in the U.S., suggests Slashdot reader UnknowingFool (with variable regional pricing). "At 5.2M wishes, it was the most wish listed game on Steam. In Brazil, the local price was 74.95 Brazil Real or 13.94 USD." In the age of $70+ AAA games with additional costs, not everyone celebrated the consumer friendly price. Some independent game developers have expressed concern that their games may not sell as well compared to Silksong and cannot afford to charge less. From ScreenRant: Hollow Knight: Silksong's unbelievably low price point of just $19.99 is exceptionally good value for the consumer. It is an incredibly lengthy game that is only marginally more expensive than its predecessor... it is proving to be a source of controversy for other indie developers who believe it will distort players' expectations.

Could Heart Attacks Be Triggered By Infections?

Slashdot.org - Sat, 09/13/2025 - 15:34
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

Slashdot.org - Sat, 09/13/2025 - 14:34
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

Slashdot.org - Sat, 09/13/2025 - 13:34
"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.org - Sat, 09/13/2025 - 12:34
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

Slashdot.org - Sat, 09/13/2025 - 11:34
"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."
