Exercise is the most potent medical intervention known, according to Stanford University researchers who mapped its molecular effects across body tissues. In a study examining sedentary and exercising rats over eight weeks, scientists found comprehensive changes in every tissue examined, from fat cells to mitochondria, with exercise often reversing disease-related molecular changes. The findings explain how exercise reduces heart disease and cancer risks by 50%.

MIT scientists have pinpointed the origin of a fast radio burst (FRB) to within 10,000 kilometers of a neutron star, settling a long-standing debate about these cosmic phenomena. Using a novel technique analyzing signal scintillation, researchers determined that FRB 20221022A, detected in 2022 from a galaxy 200 million light-years away, emerged from the star's turbulent magnetosphere rather than from a distant shockwave.

The findings, published in Nature, provide the first conclusive evidence that FRBs can originate in the extreme magnetic environment immediately surrounding these ultra-compact objects.

SvarDOS, a compact open-source operating system derived from DR-DOS, has switched to using the EDRDOS kernel, marking a shift from its FreeDOS distribution roots. The change allows the operating system to fit on a single 1.4MB floppy disk while offering a network-capable package manager that can fetch from a repository of over 400 packages.

Unlike its rival FreeDOS, SvarDOS can run Microsoft Windows 3.1 natively, though the capability currently requires additional configuration. The system maintains compatibility with legacy DOS applications while providing modern features like FAT32 support and network connectivity.

AI is unlocking ancient texts previously thought unreadable, potentially revolutionizing historical research, according to a Nature article. Neural networks have successfully decoded burned Roman scrolls from Herculaneum, deciphered ancient Chinese oracle bones, and translated vast Korean royal archives.

In a breakthrough achievement, researchers used AI to reveal 16 columns of Greek philosophical text from a charred Herculaneum scroll that had been unreadable for 2,000 years. The technology could help scholars access hundreds more unopened scrolls from Herculaneum and other historical collections worldwide.

Belgium has become the EU first country to ban the sale of disposable vapes in an effort to stop young people from becoming addicted to nicotine and to protect the environment. From a report: The sale of disposable electronic cigarettes is banned in Belgium on health and environmental grounds from 1 January. A ban on outdoor smoking in Milan came into force on the same day, as EU countries discuss tighter controls on tobacco.

Announcing the ban last year, Belgium's health minister, Frank Vandenbroucke, described electronic cigarettes as an "extremely harmful" product that damages society and the environment. "Disposable e-cigarettes is a new product simply designed to attract new consumers," he told the Associated Press. "E-cigarettes often contain nicotine. Nicotine makes you addicted to nicotine. Nicotine is bad for your health."

India has once again pushed back a contentious plan to limit major technology companies' control of the nation's digital payments system, extending a regulatory uncertainty that has weighed on the sector for years. From a report: The National Payments Corporation of India said on Tuesday it would extend the deadline for implementing a 30% cap on any individual app's share of transactions on the Unified Payments Interface, or UPI, the country's ubiquitous digital payments network, to December 31, 2026.

The decision provides temporary relief to Walmart-backed PhonePe and Google Pay, which together handle more than 85% of transactions on UPI. The network, which processes over 13 billion transactions monthly, has become the backbone of India's digital economy since its launch eight years ago.

Thousands of copyrighted works from 1929, including Mickey Mouse's first speaking appearance and original versions of comic characters Popeye and Tintin, entered the U.S. public domain on January 1, 2025, as their 95-year copyright terms expired.

Popeye debuted in E.C. Segar's "Thimble Theatre" comic strip, while Tintin first appeared in Georges Remi's "Les Aventures de Tintin." These original character versions can now be freely used without permission or fees. Literary classics joining the public domain include William Faulkner's "The Sound and the Fury," Ernest Hemingway's "A Farewell to Arms," and Virginia Woolf's "A Room of One's Own."

Musical compositions entering the public domain include George Gershwin's "An American in Paris," Maurice Ravel's "Bolero," and Fats Waller's "Ain't Misbehavin'." The original 1929 recordings remain protected until 2030 under separate copyright rules.

Notable films becoming public domain include the Marx Brothers' first feature "The Cocoanuts," Alfred Hitchcock's first sound film "Blackmail," and several Mickey Mouse animations where the character debuts his white gloves and speaks his first words. Sound recordings from 1924, including performances by Marian Anderson and George Gershwin, also entered the public domain under the Music Modernization Act's 100-year term for historical recordings.

The Securities and Exchange Commission wrote off nearly $10 billion in uncollected fines over the past decade, with $1.4 billion written off in 2023 alone, WSJ reported, citing internal data.

While the agency reported $4.9 billion in sanctions last year, it typically collects only two-thirds of imposed penalties. The SEC stopped disclosing collection rates in 2019. In fiscal 2024, it collected just 23% of $8.2 billion in reported sanctions, including a $4.4 billion judgment against cryptocurrency firm Terraform Labs that will likely go unpaid due to bankruptcy proceedings.

Food prices continue climbing, posing challenges for U.S. consumers and policymakers, with average food-at-home prices recording their largest annual increase in November. While some commodities like wheat and corn have seen price drops, key breakfast staples remain expensive due to global supply disruptions from disease, weather, and reduced production.

A filing in an antitrust lawsuit against some of the nation's top universities alleges the schools overcharged students by $685 million in a "price-fixing" scheme, raising serious questions about their past admission and financial aid policies. From a report: Documents and testimony from officials at Georgetown University, the University of Notre Dame, the University of Pennsylvania, MIT and other elite schools suggest they appeared to favor wealthy applicants despite their stated policy of accepting students without regard for their financial circumstances. That "need-blind" policy allowed the schools to collaborate on financial aid under federal law, but plaintiffs in the case say the colleges violated the statute by considering students' family income.

Every year, according to a motion filed in federal court Monday night, Georgetown's then-president would draw up a list of about 80 applicants based on a tracking list that often included information about their parents' wealth and past donations, but not the applicants' transcripts, teacher recommendations or personal essays. "Please Admit," was often written at the top of the list, the lawsuit contends -- and almost all of the applicants were. Former students accuse 17 elite schools, including most of the Ivy League, of colluding to limit the financial aid packages of working- and middle-class students. The claimed damages of $685 million, which were detailed in the court filing Monday night, would automatically triple to more than $2 billion under U.S. antitrust laws.

An anonymous reader quotes a report from Fast Company: Insurance companies that stopped providing home coverage to hundreds of thousands of Californians in recent years as wildfires became more destructive will have to again provide policies in fire-prone areas if they want to keep doing business in California under a state regulation announced Monday. The rule will require home insurers to offer coverage in high-risk areas, something the state has never done, Insurance Commissioner Ricardo Lara's office said in a statement. Insurers will have to start increasing their coverage by 5% every two years until they hit the equivalent of 85% of their market share. That means if an insurer writes 20 out of every 100 state policies, they'd need to write 17 in a high-risk area, Lara's office said.

Major insurers like State Farm and Allstate have stopped writing new policies in California due to fears of massive losses from wildfires and other natural disasters. In exchange for increasing coverage, the state will let insurance companies pass on the costs of reinsurance to California consumers. Insurance companies typically buy reinsurance to avoid huge payouts in case of natural disasters or catastrophic loss. California is the only state that doesn't already allow the cost of reinsurance to be borne by policy holders, according to Lara's office. [...] The requirement is under review by the Office of Administrative Law before it takes effect within 30 days. "Californians deserve a reliable insurance market that doesn't retreat from communities most vulnerable to wildfires and climate change," Lara said in a statement. "This is a historic moment for California."

Opponents of the rule say that could hike premiums by 40% and doesn't require new policies to be written at a fast enough pace. The state did not provide a cost analysis for potential impact on consumers. "This plan is of the insurance industry, by the insurance industry, and for the industry," Jamie Court, president of Consumer Watchdog, said in a statement.

Research from Zhejiang Agriculture and Forestry University reveals a concerning correlation between micro and nanoplastic (MNP) concentrations in damaged human tissues and various health conditions, including inflammatory bowel disease, thrombosis, and cancer. Phys.Org reports: In the study, "Mapping micro(nano)plastics in various organ systems: Their emerging links to human diseases?" published in TrAC Trends in Analytical Chemistry, investigators collected 61 available research articles for MNP detection in human tissues, plus 840 articles on MNP toxicological mechanisms. Data came from spectroscopy, microscopy, and pyrolysis-gas chromatography/mass spectrometry investigations to identify polymer types in different tissues. Toxicological studies employed cell models and animal experiments to examine oxidative stress, inflammatory responses, and related signaling pathways.

The studies documented particles detected in skin, arteries, veins, thrombi, bone marrow, testes, semen, uterus, and placenta. MNPs were found in the digestive system, from saliva to feces, liver, and gallstones. Within the respiratory system, MNPs were everywhere, including lung tissue, with microscopic fibers common in bronchoalveolar lavage fluid and sputum. Positive correlations emerged between particle abundance and specific disorders, such as inflammatory bowel disease, thrombosis, cervical cancer, and uterine fibroids. Toxicological tests showed possible MNP-triggered oxidative stress, mitochondrial dysfunction, inflammatory responses, and apoptosis in various cell types, along with organ-level concerns like neurodegenerative disease onset when crossing the blood-brain barrier.

A critically important signal in the metadata discovered by the researchers was that measured levels of MNPs tended to be higher in tissues with lesions than in non-lesioned tissues. These included inflamed intestines, fibrotic lungs, or cancerous growths, suggesting a potential link between MNP buildup and local pathology. There is an intriguing "what came first, the chicken or the egg" problem with lesions having higher concentrations of MNPs. [...] In the case of "what came first, the lesion or the microplastic," it is possible that MNPs contribute to inflammation, oxidative stress, and cellular damage, which can cause or worsen tissue lesions. But it is also possible that these lesions accumulate more MNPs in already damaged tissue areas. While the current findings do not provide a direct cause-and-effect relationship, they offer good targets for further study.

Tom's Hardware reports that NATO is developing an advanced system to address the growing number of undersea cable disruptions observed in recent years. Known as HEIST (Hybrid Space-Submarine Architecture Ensuring Infosec of Telecommunications), the project is designed to significantly enhance the resilience of undersea communication networks. HEIST will enable damage detection with an accuracy of one meter, facilitate rapid data rerouting through satellite networks when disruptions occur, and establish open-source protocols to foster global collaboration. From the report: Satellites are the primary backups to undersea cables, but their bandwidth is far behind physical connections. For example, Google's latest fiber-optic lines can hit 340 terabits per second. In contrast, the frequency used by most satellites -- 12 to 18GHz -- can only handle about 5 gigabits per second or about 0.0015% of the maximum throughput of Google's fiber connection.

Work is underway to upgrade satellites from radio transmissions to lasers, increasing the speed by about 40 times to 200 Gbps. Starlink already uses this technology to communicate between its satellites, while Amazon is also developing it for its own Project Kuiper. However, it still faces challenges, like poor visibility and targeting precision between the satellite and ground station.

Because this is a major NATO project, the alliance plans to open-source part of the process. Making it public would allow anyone interested to find holes and make many iterations. Gregory Falco, the NATO Country Director for HEIST, believes that this is the fastest way for the project to achieve its goals and help prevent any catastrophic loss of data transmission in case of deliberate attacks against these underwater infrastructures in international waters.

An anonymous reader quotes a report from The Guardian: When the scientist and inventor Prof Archibald Montgomery Low predicted "a day in the life of a man of the future" one century ago, his prophecies were sometimes dismissed as "ruthlessly imaginative." They included, reported the London Daily News in 1925, "such horrors" as being woken by radio alarm clock; communications "by personal radio set"; breakfasting "with loudspeaker news and television glimpses of events"; shopping by moving stairways and moving pavements. One hundred years after Low's publication of his book The Future some of his forecasts were spot on. Others, including his prophecy that everyone would be wearing synthetic felt one-piece suits and hats, less so.

Researchers from the online genealogy service Findmypast, have excavated accounts of Low's predictions from its extensive digital archive of historical newspapers available to the public and included them in a collection on its website of forecasts made for 2025 by people a century ago. Low, born in 1888, was an engineer, research physicist, inventor and author. A pioneer in many fields, he invented the first powered drone, worked on the development of television, was known as the "father of radio guidance systems" for his work on planes, torpedo boats and guided rockets and reportedly attracted at least two unsuccessful assassination attempts by the Germans. "It's amazing that a century ago, one visionary scientist could predict how emerging technology -- in its infancy at the time -- could have changed the world by 2025," said Jen Baldwin, a research specialist at Findmypast. "It makes you stop to wonder how the advancements we see around us today will be experienced by our own descendants."

Generation Beta, starting in 2025 and lasting until around 2039, will grow up deeply immersed in AI and smart technology, facing pressing societal challenges like climate change and global shifts while potentially being shielded from excessive screen time by tech-savvy Gen Z parents. NBC News reports: Start and end dates of generations can be murky, but Generation Beta will keep being born until around 2039. Before them, Gen Alpha stretched from 2010 to 2024, Gen Z from around 1996 to 2010, and millennials from 1981 to 1996. The upcoming generation "will inherit a world grappling with major societal challenges," wrote demographer and futurist Mark McCrindle in a blog post. "With climate change, global population shifts, and rapid urbanisation at the forefront, sustainability will not just be a preference but an expectation." [...]

Just like Gen Z and Gen Alpha, Gen Beta will grow up with social media, though it's still unknown how those mediums will evolve in the next decade-plus. But other experts predict that Gen Z parents might choose to shield their kids from being chronically online, a stereotype that has come to define Gen Alpha. While older millennial parents tend to integrate technology into their Gen Alpha kids' lives, McCrindle wrote that Gen Z parents might take a different approach with their future Gen Beta children. "Generation Z know more about both the positives and challenges that come with social media use from a young age," McCrindle wrote. "As the most technologically savvy generation of parents, Gen Z see the benefits of technology and screen time, but equally they see the downsides of it and are pushing back on technology and the age at which their children access and engage with it."

Alibaba is cutting prices on its large language models by up to 85% to attract more enterprise users and strengthen its position in China's competitive AI market. CNBC reports: The Hangzhou-based e-commerce firm's cloud computing division, Alibaba Cloud, said in a WeChat post that it's offering the price cuts on its visual language model, Qwen-VL, which is designed to perceive and understand both texts and images. [...] Major Chinese tech firms including Alibaba, Tencent, Baidu, JD.com, Huawei and TikTok parent company Bytedance have all launched their own large language models over the past 18 months, looking to capitalize on the hype around the technology.

It's not the first time Alibaba has announced price cuts to incentivize businesses to use its AI products. In February, the company announced price reductions of as much as 55% on a wide range of core cloud products. More recently, in May, the company reduced prices on its Qwen AI model by as much as 97% in a bid to boost demand. [...] In Alibaba's case, the company is focusing its LLM efforts on the enterprise segment rather than launching a consumer AI chatbot like OpenAI's ChatGPT. In May, the company said its Qwen models have been deployed by over 90,000 enterprise users.

Venezuela's Supreme Court on Monday fined TikTok $10 million for failing to prevent viral challenges allegedly linked to the deaths of three children. It also ordered the platform to establish a local office to oversee content compliance with national laws. The Associated Press reports: Judge Tania D'Amelio said TikTok had acted in a negligent manner and gave it eight days to pay the fine [...]. The judge did not explain how Venezuela would force TikTok, whose parent company is based in China, to pay the fine. Venezuela has blocked dozens of websites in previous years for not complying with regulations set by its telecommunications commission.

In November, Venezuelan President Nicolas Maduro blamed TikTok for the death of a 12-year-old girl who allegedly died after participating in a TikTok challenge that involved taking tranquilizer pills and not falling asleep. Venezuela's Education Minister Hector Rodriguez also said last month that a 14-year-old died after taking part in a TikTok challenge that involved sniffing substances. And on Nov. 21, Venezuela's attorney general blamed video challenges on TikTok for the death of a third child.

An anonymous reader quotes a report from Electrek: A new study published in the journal Renewable Energy (PDF) uses data from the state of California to demonstrate that no blackouts occurred when wind-water-solar electricity supply exceeded 100% of demand on the state's main grid for a record 98 of 116 days from late winter to early summer 2024 for an average (maximum) of 4.84 (10.1) hours per day. Compared to the same period in 2023, solar output in California is up 31%, wind power is up 8%, and batteries are up a staggering 105%. Batteries supplied up to 12% of nighttime demand by storing and redistributing excess solar energy.

And here's the kicker: California's high electricity prices aren't because of wind, water, and solar energy. (That issue is primarily caused (PDF) by utilities recovering the cost of wildfire mitigation, transmission and distribution investments, and net energy metering.) In fact, researchers from Stanford, Lawrence Berkeley National Laboratory, and the University of California, Berkeley found that states with higher shares of renewable energy tend to see lower electricity prices. The takeaway -- and the data backs it up -- is that a large grid dominated by wind, water, and solar is not only feasible, it's also reliable.

The Metropolitan Transportation Authority has announced plans to retire its iconic R46 subway cars, triggering nostalgia among New Yorkers who cherished their distinctive seating arrangement. The fleet -- which has served A, C, N, R, Q, and W lines for five decades -- will be replaced by R211 cars expected for delivery in 2027.

The R46's perpendicular seating configuration, designed for comfort during long trips to destinations like Coney Island, encouraged social interaction among passengers, according to New York Transit Museum director Concetta Bencivenga. The new R211 cars will feature longitudinal seating to improve passenger flow and reduce platform waiting times. Currently, 696 of the original 754 R46 cars remain in service. The replacement R211 cars will include security cameras, wider seats, improved signage, and better lighting.
