Commercial Tea Bags Release Millions of Microplastics, Entering Human Intestinal Cells

3 hours 14 min ago
A new study finds that polymer-based commercial tea bags release billions of nanoplastics and microplastics when infused. It also shows for the first time that these particles are capable of being absorbed by human intestinal cells, entering the bloodstream, and potentially affecting human health. The study by the Mutagenesis Group of the UAB Department of Genetics and Microbiology has been published in the journal Chemosphere. Medical Xpress reports: The tea bags used for the research were made from the polymers nylon-6, polypropylene and cellulose. The study shows that, when brewing tea, polypropylene releases approximately 1.2 billion particles per milliliter, with an average size of 136.7 nanometers; cellulose releases about 135 million particles per milliliter, with an average size of 244 nanometers; while nylon-6 releases 8.18 million particles per milliliter, with an average size of 138.4 nanometers. To characterize the different types of particles present in the infusion, a set of advanced analytical techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy (ATR-FTIR), dynamic light scattering (DLS), laser Doppler velocimetry (LDV), and nanoparticle tracking analysis (NTA) were used. The particles were stained and exposed for the first time to different types of human intestinal cells to assess their interaction and possible cellular internalization. The biological interaction experiments showed that mucus-producing intestinal cells had the highest uptake of micro and nanoplastics, with the particles even entering the cell nucleus that houses the genetic material. The result suggests a key role for intestinal mucus in the uptake of these pollutant particles and underscores the need for further research into the effects that chronic exposure can have on human health.

Space Station Keeps Dodging Debris From China's 2007 Satellite Weapon Test

6 hours 14 min ago
fjo3 shares a report from the Washington Post: The International Space Station had to fire thrusters from a docked spacecraft last month to avoid a piece of debris that has been circling the globe for the nearly 18 years since the Chinese government blasted apart one of its own satellites in a weapons test. The evasive maneuver was the second in just six days for the space station, which has four NASA astronauts and three Russian cosmonauts aboard. That is the shortest interval ever between such actions, illustrating the slowly worsening problem of space junk in orbit. Debris is an increasingly vexing issue not only for NASA, but also for companies such as SpaceX and OneWeb seeking to protect the thousands of small satellites they send into space to provide high-speed internet. The debris cloud from China's 2007 destruction of the Fengyun 1C satellite remains one of the most persistent threats in orbit, with about 3,500 fragments still posing collision risks to spacecraft. Since 2020, the ISS has performed 15 debris-avoidance maneuvers. The evasive maneuver was performed after a Space Force warning. According to the report, Space Force now tracks over 47,200 objects in orbit, issuing approximately 23 daily collision warnings -- up from just six per day five years ago.

New Physics Sim Trains Robots 430,000 Times Faster Than Reality

Mon, 12/23/2024 - 22:30
An anonymous reader quotes a report from Ars Technica: On Thursday, a large group of university and private industry researchers unveiled Genesis, a new open source computer simulation system that lets robots practice tasks in simulated reality 430,000 times faster than in the real world. Researchers also plan to introduce an AI agent to generate 3D physics simulations from text prompts. The accelerated simulation means a neural network for piloting robots can spend the virtual equivalent of decades learning to pick up objects, walk, or manipulate tools during just hours of real computer time. "One hour of compute time gives a robot 10 years of training experience. That's how Neo was able to learn martial arts in a blink of an eye in the Matrix Dojo," wrote Genesis paper co-author Jim Fan on X, who says he played a "minor part" in the research. Fan has previously worked on several robotics simulation projects for Nvidia. [...] The team also announced they are working on the ability to generate what it calls "4D dynamic worlds" -- perhaps using "4D" because they can simulate a 3D world in motion over time. The system will reportedly use vision-language models (VLMs) to generate complete virtual environments from text descriptions (similar to "prompts" in other AI models), utilizing Genesis's own simulation infrastructure APIs to create the worlds.

Gordon Mah Ung, PCWorld Editor and Renowned Hardware Journalist, Dies At 58

Mon, 12/23/2024 - 21:02
PCWorld's Jon Phillips pays tribute to Gordon Mah Ung, "our hardware guru, host of The Full Nerd, exemplary tech journalist, and very good friend." He passed away over the weekend after a hard-fought battle with pancreatic cancer. He was 58. From the report: With more than 25 years' experience covering computer tech broadly and computer chips specifically, Gordon's dogged reporting, one-of-a-kind personality, and commitment to journalistic standards touched many, many lives. He will be profoundly missed by co-workers, industry sources, and the PC enthusiasts who read his words and followed him as a video creator. Gordon studied journalism at San Francisco State University and then worked as a police reporter for the Contra Costa Times in the late 1990s. In 1997, he joined Computerworld (a PCWorld sister publication) before I recruited him to join boot magazine (later re-launched as Maximum PC), where he would ultimately lead hardware coverage for 16 years.

Engineers Achieve Quantum Teleportation Over Active Internet Cables

Mon, 12/23/2024 - 20:25
Researchers at Northwestern University have successfully achieved quantum teleportation over a standard fiber optic cable carrying regular internet traffic, demonstrating that quantum and classical communication can coexist on existing infrastructure. The research has been published in the journal Optica. TechSpot reports: Nobody thought it would be possible to achieve this, according to Professor Prem Kumar, who led the study. "Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure. Basically, it opens the door to pushing quantum communications to the next level." "By performing a destructive measurement on two photons -- one carrying a quantum state and one entangled with another photon -- the quantum state is transferred onto the remaining photon, which can be very far away," said Jordan Thomas, a Ph.D. candidate in Kumar's laboratory and the paper's first author. "The photon itself does not have to be sent over long distances, but its state still ends up encoded onto the distant photon." Prior to this study, many researchers were skeptical about the feasibility of quantum teleportation in cables carrying classic communications. The concern was that the entangled photons would be overwhelmed by the millions of other light particles present in the fiber optic cables. However, Kumar and his team were able to devise a solution. Through extensive studies of light scattering within fiber optic cables, the researchers identified a less crowded wavelength of light to place their photons. They also implemented special filters to reduce noise from regular Internet traffic. Kumar explained that he and his team conducted a meticulous analysis of light scattering patterns and strategically positioned their photons at a critical point where the scattering effect was minimized. To validate their method, the team set up a 30-kilometer-long (18.6 miles) fiber optic cable with a photon at each end. They simultaneously transmitted quantum information and high-speed Internet traffic through the cable. The quality of the quantum information was measured at the receiving end while executing the teleportation protocol by making quantum measurements at the mid-point. The results showed that the quantum information was successfully transmitted, even in the presence of busy internet traffic.

Critics Decry Vietnam's 'Draconian' New Internet Law

Mon, 12/23/2024 - 19:45
Vietnam's Decree 147 mandates social media users on platforms like Facebook and TikTok to verify their identities and requires tech companies to store and share user data with authorities upon request, sparking concerns over increased censorship, self-censorship, and threats to free expression. Furthermore, the decree imposes restrictions on gaming time for minors and limits livestreaming to verified accounts. It becomes effective on Christmas Day. The Guardian reports: Decree 147, as it is known, builds on a 2018 cybersecurity law that was sharply criticized by the US, EU and internet freedom advocates who said it mimics China's repressive internet censorship. [...] Critics say that decree 147 will also expose dissidents who post anonymously to the risk of arrest. "Many people work quietly but effectively in advancing the universal values of human rights," Ho Chi Minh City-based blogger and rights activist Nguyen Hoang Vi told AFP. She warned that the new decree "may encourage self-censorship, where people avoid expressing dissenting views to protect their safety -- ultimately harming the overall development of democratic values" in the country. Le Quang Tu Do, of the ministry of information and communications (MIC), told state media that decree 147 would "regulate behavior in order to maintain social order, national security, and national sovereignty in cyberspace." [...] Human Rights Watch is calling on the government to repeal the "draconian" new decree. "Vietnam's new Decree 147 and its other cybersecurity laws neither protect the public from any genuine security concerns nor respect fundamental human rights," said Patricia Gossman, HRW's associate Asia director. "Because the Vietnamese police treat any criticism of the Communist party of Vietnam as a national security matter, this decree will provide them with yet another tool to suppress dissent."

Health Care Giant Ascension Says 5.6 Million Patients Affected In Cyberattack

Mon, 12/23/2024 - 19:02
An anonymous reader quotes a report from Ars Technica: Health care company Ascension lost sensitive data for nearly 5.6 million individuals in a cyberattack that was attributed to a notorious ransomware gang, according to documents filed with the attorney general of Maine. Ascension owns 140 hospitals and scores of assisted living facilities. In May, the organization was hit with an attack that caused mass disruptions as staff was forced to move to manual processes that caused errors, delayed or lost lab results, and diversions of ambulances to other hospitals. Ascension managed to restore most services by mid-June. At the time, the company said the attackers had stolen protected health information and personally identifiable information for an undisclosed number of people. A filing Ascension made earlier in December revealed that nearly 5.6 million people were affected by the breach. Data stolen depended on the particular person but included individuals' names and medical information (e.g., medical record numbers, dates of service, types of lab tests, or procedure codes), payment information (e.g., credit card information or bank account numbers), insurance information (e.g., Medicaid/Medicare ID, policy number, or insurance claim), government identification (e.g., Social Security numbers, tax identification numbers, driver's license numbers, or passport numbers), and other personal information (such as date of birth or address). Ascension is now in the process of notifying affected individuals. The organization is also offering two years of credit and fraud monitoring, a $1 million insurance reimbursement policy, and managed ID theft recovery services. The services became effective last Thursday. Further reading: Black Basta Ransomware Attack Brought Down Ascension IT Systems, Report Finds

Apple Sends Spyware Victims To Nonprofit Security Lab 'Access Now'

Mon, 12/23/2024 - 18:20
Since 2021, Apple has been sending threat notifications to certain users, informing them that they may have been individually targeted by mercenary spyware attacks. When victims of spyware reach out to Apple for help, TechCrunch reports, "Apple doesn't tell the targets to get in touch with its own security engineers." Instead, Apple directs them to the nonprofit security lab Access Now, "which runs a digital helpline for people in civil society who suspect they have been targets of government spyware." While some view this as Apple sidestepping responsibility, cybersecurity experts agree that Apple's approach -- alerting victims, directing them to specialized support, and recommending tools like Lockdown Mode -- has been a game changer in combating mercenary spyware threats. From the report: For people who investigate spyware, Apple sharing spyware notifications with victims represented a turning point. Before the notifications, "We were just like in the dark, not knowing who to check," according to Access Now's legal counsel Natalia Krapiva. "I think it's one of the greatest things that's happened in the sphere of this kind of forensic investigations and hunting of sophisticated spyware," Krapiva told TechCrunch. Now, when someone or a group of people get a notification from Apple, they are warned that something potentially anomalous is happening with their device, that someone is targeting them, and that they need to get help. And Apple tells them exactly where to get it, according to Scott-Railton, who said Access Now's helpline is the right place to go because "the helpline is able to do good, systematic triage work and support." Krapiva said that the helpline is staffed by more than 30 people, supported by others who work in other departments of the nonprofit. So far in 2024, Krapiva said Access Now received 4,337 tickets through the helpline. For anyone alerted by a notification, Apple tells those targets and victims of spyware to update their iOS software and all their apps. Apple also suggests the user switches on Lockdown Mode, an opt-in iOS security feature that has stopped spyware attacks in the past by limiting device features that are often exploited to plant spyware. Apple said last year that it is not aware of any successful spyware infection against someone who used Lockdown Mode.

US Targets China With Probe Into Semiconductor Industry

Mon, 12/23/2024 - 17:40
The Biden administration has launched a Section 301 investigation into China's semiconductor industry, citing concerns over non-market practices, supply chain dependencies, and national security risks. The Hill reports: In a fact sheet, the White House said China "routinely engages in non-market policies and practices, as well as industrial targeting, of the semiconductor industry" that harms competition and creates "dangerous supply chain dependencies." The Biden administration said the Office of the United States Trade Representative would launch a Section 301 investigation to examine China's targeting of semiconductor chips for dominance, an effort to see whether the practices are unfairly hurting U.S. trade and take potential action. The investigation will broadly probe Chinese nonmarket practices and policies related to semiconductors and look at how the products are incorporated into industries for defense, auto, aerospace, medical, telecommunications and power. It will also examine production of silicon carbide substrates or other wafers used as inputs for semiconductors. The probe launches four weeks before President-elect Donald Trump takes office. "The effort could offer Trump a ready avenue to begin imposing some of the hefty 60% tariffs he has threatened on Chinese imports," notes Reuters. "Departing President Joe Biden has already imposed a 50% U.S. tariff on Chinese semiconductors that starts on Jan. 1. His administration also has tightened export curbs on advanced artificial intelligence and memory chips and chipmaking equipment."

Encyclopedia Britannica Is Now an AI Company

Mon, 12/23/2024 - 17:00
An anonymous reader quotes a report from Gizmodo: Once an icon of the 20th century seen as obsolete in the 21st, Encyclopedia Britannica -- now known as just Britannica -- is all in on artificial intelligence, and may soon go public at a valuation of nearly $1 billion, according to the New York Times. Until 2012 when printing ended, the company's books served as the oldest continuously published, English-language encyclopedias in the world, essentially collecting all the world's knowledge in one place before Google or Wikipedia were a thing. That has helped Britannica pivot into the AI age, where models benefit from access to high-quality, vetted information. More general-purpose models like ChatGPT suffer from hallucinations because they have hoovered up the entire internet, including all the junk and misinformation. While it still offers an online edition of its encyclopedia, as well as the Merriam-Webster dictionary, Britannica's biggest business today is selling online education software to schools and libraries, the software it hopes to supercharge with AI. That could mean using AI to customize learning plans for individual students. The idea is that students will enjoy learning more when software can help them understand the gaps in their understanding of a topic and stay on it longer. Another education tech company, Brainly, recently announced that answers from its chatbot will link to the exact learning materials (i.e. textbooks) they reference. Britannica's CEO Jorge Cauz also told the Times about the company's Britannica AI chatbot, which allows users to ask questions about its vast database of encyclopedic knowledge that it collected over two centuries from vetted academics and editors. The company similarly offers chatbot software for customer service use cases. Britannica told the Times it is expecting revenue to double from two years ago, to $100 million.

Sweden Says China Denied Request For Prosecutors To Board Ship Linked To Severed Cables

Mon, 12/23/2024 - 16:22
Sweden has accused China of denying a request for Swedish prosecutors to board a Chinese ship that has been linked to the cutting of two undersea cables in the Baltic despite Beijing pledging "cooperation" with regional authorities. From a report: The Yi Peng 3 left the waters it had been anchored in since last month on Saturday -- despite an ongoing investigation. The ship was tracked sailing over the two fibre-optic cables, one between Sweden and Lithuania, and the other linking Helsinki and Germany, at around the time that they were cut on 17 and 18 November in Swedish territorial waters close to the Swedish islands of Gotland and Oland. For more than a month afterwards it was anchored in the Kattegat strait between Sweden and Denmark where it was being observed by multiple countries and was boarded by Swedish police and other authorities last week. The ship tracking site VesselFinder showed the Yi Peng 3 heading north out of the strait on Saturday and on Monday China confirmed the ship had left in order to "ensure the physical and mental wellbeing of the crew." The Swedish foreign minister, Maria Malmer Stenergard, said on Monday that China had not cooperated with Sweden's request to allow Swedish prosecutors onboard.

Google's Counteroffer To the Government Trying To Break It Up is Unbundling Android Apps

Mon, 12/23/2024 - 15:01
An anonymous reader shares a report: The Department of Justice's list of solutions for fixing Google's illegal antitrust behavior and restoring competition in the search engine market started with forcing the company to sell Chrome, and late Friday night, Google responded with a list of its own. Instead of breaking off Chrome, Android, or Google Play as the DOJ's filing considers, Google's proposed fixes aim at the payments it makes to companies like Apple and Mozilla for exclusive, prioritized placement of its services, its licensing deals with companies that make Android phones, and contracts with wireless carriers. They don't address a DOJ suggestion about possibly forcing Google to share its valuable search data with other companies to help their products catch up.

Electric Aircraft Startup Lilium Ceases Operations, 1,000 Workers Laid Off

Mon, 12/23/2024 - 14:22
Lilium, once a darling in the nascent industry of electric aircraft that raised more than $1 billion before going public, has ceased operations and laid off about 1,000 workers after efforts to gain financing and exit insolvency failed. From a report: Lilium co-founder and CEO Patrick Nathen confirmed on LinkedIn that the 10-year-old company had stopped operating. "After 10 years and 10 months, it is a sad fact that Lilium has ceased operations. The company that Daniel, Sebastian, Matthias and I founded can no longer pursue our shared belief in more environmentally friendly aviation. This is heartbreaking and the timing feels painfully ironic," wrote Nathen. The layoffs cover the bulk of the company's workforce and come a few days after about 200 workers were let go, according to a regulatory filing on December 16.

Government To Name 'Key Witness' Who Provided FBI With Backdoored Encrypted Chat App Anom

Mon, 12/23/2024 - 13:45
An anonymous reader shares a report: A lawyer defending an alleged distributor of Anom, the encrypted phone company for criminals that the FBI secretly ran and backdoored to intercept tens of millions of messages, is pushing to learn the identity of the confidential human source (CHS) who first created Anom and provided it to the FBI starting the largest sting operation in history, according to recently filed court records. The government says it will provide that identity under discovery, but the CHS may also be revealed in open court if they testify. The move is significant in that the CHS, who used the pseudonym Afgoo while running Anom, is a likely target for retaliation from violent criminals caught in Anom's net. The Anom case, called Operation Trojan Shield, implicated hundreds of criminal syndicates in more than 100 countries. That includes South American cocaine traffickers, Australian biker gangs, and kingpins hiding in Dubai. Anom also snagged specific significant drug traffickers like Hakan Ayik, who authorities say heads the Aussie Cartel which brought in more than a billion Australian dollars in profit annually. Court records say, however, that if this defendant's case goes to trial, the lawyer believes Afgoo will be the "government's key witness."

WhatsApp Scores Historic Victory Against NSO Group in Long-Running Spyware Hacking Case

Mon, 12/23/2024 - 12:22
A U.S. judge has ruled that Israeli spyware maker NSO Group breached hacking laws by using WhatsApp to infect devices with its Pegasus spyware. From a report: In a historic ruling on Friday, a Northern California federal judge held NSO Group liable for targeting the devices of 1,400 WhatsApp users, violating state and federal hacking laws as well as WhatsApp's terms of service, which prohibit the use of the messaging platform for malicious purposes. The ruling comes five years after Meta-owned WhatsApp sued NSO Group, alleging the spyware outfit had exploited an audio-calling vulnerability in the messaging platform to install its Pegasus spyware on unsuspecting users' devices. WhatsApp said that more than 100 human rights defenders, journalists and "other members of civil society" were targeted by the malware, along with government officials and diplomats. In her ruling, Judge Phyllis Hamilton said NSO did not dispute that it "must have reverse-engineered and/or decompiled the WhatsApp software" to install its Pegasus spyware on devices, but raised questions about whether it had done so before agreeing to WhatsApp's terms of service.

Nissan and Honda Agree To Merge

Mon, 12/23/2024 - 11:43
Honda sketched plans for a drawn-out deal that amounts to a takeover of Nissan in all but name, as Japan's automakers struggle to keep up in an increasingly competitive global car industry. From a report: The two announced a tentative agreement Monday to set up a joint holding company that will aim to list shares in August 2026. While their executives called the transaction a merger, Honda will take the lead in forming the new entity and nominate a majority of its directors. Nissan's partner Mitsubishi may also participate in the deal. Honda and Nissan both are having trouble contending with ascendant domestic automakers in China, which surpassed Japan as the world's largest car-exporting nation last year and is pulling further ahead in 2024.
