Apple is offering rare discounts of up to 500 yuan ($68.50) on its latest iPhone models in China, as the U.S. tech giant moves to defend its market share against rising competition from domestic rivals like Huawei. From a report: The four-day promotion, running from Jan. 4-7, applies to several iPhone models when purchased using specific payment methods, according to its website.

The flagship iPhone 16 Pro with a starting price of 7,999 yuan and the iPhone 16 Pro Max with a starting price of 9,999 yuan will see the highest discount of 500 yuan. The iPhone 16 and iPhone 16 Plus will receive a 400 yuan reduction. The discounts come as consumers remain cautious with spending amid China's slowing economy and deflationary pressures, with the country's consumer inflation hitting a five-month low in November.

The number of active venture capital investors, firms that invest in startups, has dropped more than a quarter from a peak in 2021 [non-paywalled source], as risk-averse financial institutions focus their money on the biggest firms in Silicon Valley. From a report: The tally of VCs investing in US-headquartered companies dropped to 6,175 in 2024 -- meaning more than 2,000 have fallen dormant since a peak of 8,315 in 2021, according to data provider PitchBook.

The trend has concentrated power among a small group of mega-firms and has left smaller VCs in a fight for survival. It has also skewed the dynamics of the US venture market, enabling start-ups such as SpaceX, OpenAI, Databricks and Stripe to stay private for far longer, while thinning out funding options for smaller companies.

More than half of the $71bn raised by US VCs in 2024 was pulled in by just nine firms, according to PitchBook. General Catalyst, Andreessen Horowitz, Iconiq Growth and Thrive Capital raised more than $25bn in 2024. Many firms threw in the towel in 2024.

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.
