In Shallow Water Ships Trigger Seafloor Methane Emissions, Study Finds (msn.com) 37

An anonymous reader shared this report from the Washington Post: Ships trigger seafloor methane emissions while moving through shallow water, researchers report in Communications Earth & Environment. The scientists say the unexpected discovery has nothing to do with the type of fuel used by the ship. Instead, "ship-induced pressure changes and turbulent mixing" trigger the release of the gas from the seafloor. Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a greenhouse gas...

Container and cruise ships triggered the largest and most frequent methane emissions, but the study suggests that ships of all kinds, regardless of their type of engine or size, trigger methane emissions. Researchers said they observed emissions that were 20 times higher in the shipping lane than in undisturbed nearby areas. Given the number of ports in similarly shallow areas worldwide, it's important to learn more about emissions in shipping lanes and to better estimate their "hitherto unknown impact," study co-author Johan Mellqvist, a professor of optical remote sensing at Chalmers University of Technology in Sweden, said in a news release.

Chinese Companies Now Authorized to Conduct Foreign Cyberattacks, Sell Access to Government (msn.com) 50

"The U.S. is absolutely facing the most serious Chinese hacking ever." That's what the Washington Post was told by a China-focused consultant at security company SentinelOne: Undeterred by recent indictments alleging widespread cyberespionage against American agencies, journalists and infrastructure targets, Chinese hackers are hitting a wider range of targets and battling harder to stay inside once detected, seven current and former U.S. officials said in interviews. Hacks from suspected Chinese government actors detected by the security firm CrowdStrike more than doubled from 2023 to more than 330 last year and continued to climb as the new administration took over, the company said... Although the various Chinese hacking campaigns seem to be led by different government agencies and have different goals, all benefit from new techniques and from Beijing's introduction of a less constrained system for cyber offense, the officials and outside researchers told The Washington Post... Chinese intelligence, military and security agencies previously selected targets and tasked their own employees with breaking in, they said. But the Chinese government decided to take a more aggressive approach by allowing private industry to conduct cyberattacks and hacking campaigns on their own, U.S. officials said.

The companies are recruiting top hackers who discover previously unknown, or "zero-day," flaws in software widely used in the United States. Then the companies search for where the vulnerable programs are installed, hack a great many of them at once, and then sell access to multiple Chinese government customers and other security companies. That hacking-for-hire approach creates hundreds of U.S. victims instead of a few, making it hard to block attacks and to decide which were China's key targets and which were unintentionally caught in the hacks, an FBI official said, speaking on the condition of anonymity to follow agency practices... "The result of that incentive structure is that there is significantly more hacking...."

China has mastered the ability to move undetected through networks of compromised U.S. devices, so that the final connection to a target appears to be an ordinary domestic connection. That makes it easy to get around technology that blocks overseas links and puts it outside the purview of the National Security Agency, which by law must avoid scrutinizing most domestic transmissions. Beijing is increasingly focused on hacking software and security vendors that provide access to many customers at once, the FBI official said. Once access is obtained, the hackers typically add new email and collaboration accounts that look legitimate... Beyond the increased government collaboration with China's private security sector is occasional collaborating with criminal groups, said Ken Dunham, an analyst at the security firm Qualys.

The article notes that China's penetration of U.S. telecom carriers "is still not fully contained, according to the current and former officials." But in addition, the group behind that attack "has more recently shown up inside core communications infrastructure in Europe, according to John Carlin, a former top national security official in the Justice Department who represents some U.S. victims of the group." And documents leaked last year from a security contractor that works with the Chinese military and other government groups "described contracts and targets in 20 countries, with booty including Indian immigration data, logs of calls in South Korea, and detailed information on roads in Taiwan.

"It also detailed prices for some services, such as $25,000 for promised remote access to an iPhone, payment disputes with government customers and employee gripes about long hours..."

SES Completes $3 Billion Acquisition of Intelsat, Expanding Global Satellite Fleet (ses.com) 3

"The Luxembourg-based satellite company SES has now completed its acquisition of the European-based satellite company Intelsat, giving the combined company 120 active satellites in a variety of low and high Earth orbits," writes longtime Slashdot reader schwit1. "Both companies are long established, with Intelsat initially founded in the mid-1960s as a consortium of 23 nations aimed at launching the first geosynchronous communications satellites over the Atlantic and Pacific serving most of the Old World and linked to the New. The merger is an attempt by both companies to compete with the new low-orbit constellations of SpaceX, Amazon, and from China." From a press release: With a world-class network including approximately 90 geostationary (GEO), nearly 30 medium earth orbit (MEO) satellites, strategic access to low earth orbit (LEO) satellites, and an extensive ground network, SES can now deliver connectivity solutions utilizing complementary spectrum bands including C-, Ku-, Ka-, Military Ka-, X-band, and Ultra High Frequency. The expanded capabilities of the combined company will enable it to deliver premium-quality services and tailored solutions to its customers. The company's assets and networks, once fully integrated, will put SES in a strong competitive position to better serve the evolving needs of its customers including governments, aviation, maritime, and media across the globe. "Our focus is clear: to grow, to lead in high-potential markets, and to shape the future of our industry," said SES CEO Adel Al-Saleh in a statement. "This is a long-term play, and we are building with the future in mind -- growing year after year, expanding our capabilities, and creating lasting value for our customers and shareholders alike."

Fierce Network notes that the FCC is preparing to auction upper C-band spectrum (3.98-4.2 GHz), previously cleared in part by SES and Intelsat and now eyed for 5G expansion by Verizon and AT&T. With new legislative backing and industry pressure, including from CTIA and FCC Chairman Brendan Carr, the agency is being urged to act quickly to auction and open this spectrum for full-power wireless use.

Transatlantic Communications Cable Doubles As Ocean Sensor (phys.org) 5

alternative_right shares a report from Phys.org: Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have begun gathering submarine measurements via an existing infrastructure network that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables that provide us with amenities like Internet and phone service. Without interfering with their original purpose, the cables can be used as sensors to measure small variations in the light signals that run through them so that scientists can learn more about the sea. Meichen Liu and colleagues recently developed a new instrument, consisting of a receiver and a microwave intensity modulator placed at a shore station, that facilitates the approach. Their work is published in Geophysical Research Letters.

Transcontinental fiber-optic cables are divided into subsections by repeaters, instruments positioned every 50 to 100 kilometers that boost information-carrying light signals so that they remain strong on the journey to their destination. At each repeater, an instrument called a fiber Bragg grating reflects a small amount of light back to the previous repeater to monitor the integrity of the cable. By observing and timing these reflections, the new instrument measures the changes in the time it takes for the light to travel between repeaters. These changes convey information about how the surrounding water changes the shape of the cable, and the researchers used that information to infer properties such as daily and weekly water temperature and tide patterns.

Perplexity CEO Says Tech Giants 'Copy Anything That's Good' (businessinsider.com) 32

Perplexity CEO Aravind Srinivas warned young entrepreneurs that tech giants will "copy anything that's good" during a talk at Y Combinator's AI Startup School, telling founders they must "live with that fear." Srinivas said that companies raising tens of billions need to justify capital expenditures and search for new revenue streams.

Perplexity pioneered web-crawling chatbots when it launched its answer engine in December 2022, but Google's Bard added internet-crawling three months later, followed by ChatGPT in May 2023 and Anthropic's Claude in March 2025. The competition has extended to browsers, with Perplexity launching its Comet browser on July 9 and Reuters reporting that OpenAI is developing a web browser to challenge Google Chrome. Perplexity's communications head Jesse Dwyer said larger companies will "drown your voice."

Japan Sets New Internet Speed Record, Surpassing Average US Broadband Speeds By 4 Million Times 37

A team of Japanese researchers has set a new world record for internet speed, transmitting data at 125,000 gigabytes per second over 1,120 miles using a new type of 19-core optical fiber. "That's about 4 million times the average internet speed in the U.S. and would allow you to download the entire Internet Archive in less than four minutes," notes Live Science. It's also "more than twice the previous world record of 50,250 Gbps, previously set by a different team of scientists in 2024." From the report: To achieve this new speed -- which has not been independently verified -- the team developed a new form of optical fiber to send information at groundbreaking speeds over roughly the distance between New York and Florida. Details about this achievement were presented April 3 at the 48th Optical Fiber Communication Conference in San Francisco, according to a statement from Japan's National Institute of Information and Communications Technology.

The new type of optical fiber is equivalent to 19 standard optical fibers in its data transmission capacity. The new optical fiber is better suited to long-haul transmission than existing cables because the centers of all 19 fibers interact with light in the same way, so they encounter less light fluctuation, which results in less data loss. The new cable squeezes 19 separate fibers into a diameter of five-thousandths of an inch (0.127 millimeters), which is the same thickness as most existing single-fiber cables already in use. This effort means the new cable can transmit more data using existing infrastructure. [...] For this demonstration, the data ran through a transmission system 21 times, finally reaching a data receiver after traveling the equivalent of 1,120 miles.

FCC Chair Accused of 'Political Theater' to Please Net Neutrality's Foes (freepress.net) 35

The advocacy group Free Press on Friday blasted America's Federal Communications Commission chief "for an order that rips net neutrality rules off the books, without any time for public comment, following an unfavorable court ruling," reports the nonprofit progressive news site Common Dreams: A panel from the U.S. Court of Appeals for the 6th Circuit ruled in January that broadband is an "information service" instead of a "telecommunications service" under federal law, and the FCC did not have the authority to prohibit internet service providers (ISPs) from creating online "fast lanes" and blocking or throttling web content... FCC Chair Brendan Carr said in a Friday statement that as part of his "Delete, Delete, Delete" initiative, "we're continuing to clean house at the FCC, working to identify and eliminate rules that no longer serve a purpose, have been on our books for decades, and have no place in the current Code of Federal Regulations...."

Responding in a lengthy statement, Free Press vice president of policy and general counsel Matt Wood said that "the FCC's so-called deletion today is little more than political grandstanding. It's true that the rules in question were first stayed by the 6th Circuit and then struck down by that appellate court — in a poorly reasoned opinion. So today's bookkeeping maneuver changes very little in reality... There's no need to delete currently inoperative rules, much less to announce it in a summer Friday order. The only reason to do that is to score points with broadband monopolies and their lobbyists, who've fought against essential and popular safeguards for the past two decades straight...."

Wood noted that "the appeals process for this case has not even concluded yet, as Free Press and allies sought and got more time to consider our options at the Supreme Court. Today's FCC order doesn't impact either our ability to press the case there or our strategic considerations about whether to do so," he added. "It's little more than a premature housekeeping step..."

UK Full-Fiber Broadband Coverage Jumps From 12% to 78% in Five Years (ft.com) 28

The UK has transformed its broadband infrastructure in five years -- with full-fiber coverage jumping from 12% of properties in January 2020 to more than 78% by 2025, according to communications regulator Ofcom and ThinkBroadband data. Northern Ireland leads with 96% of premises in postcodes served with full-fiber connections.

The rollout accelerated after Ofcom's May 2021 regulatory framework gave other providers access to BT's Openreach ducts and poles while promising the company regulatory certainty through a "fair bet" approach that avoided price caps. The framework sparked investment from alternative networks, or "altnets," which increased homes passed from 8.2 million in 2022 to 16.4 million by 2025.

Chinese Satellites Complete First High-Altitude Rendezvous For Possible Groundbreaking Refueling (extremetech.com) 14

Two Chinese satellites, SJ-25 and SJ-21, have reportedly completed the first autonomous high-altitude orbital docking. "Although unconfirmed, this is thought to be the first orbital refueling at such a height -- the two satellites are currently over 20,000 miles from Earth," reports ExtremeTech. From the report: Orbital refueling is an important component in keeping satellites and space stations in low Earth orbit flying, but any efforts beyond that have been merely speculative until the past few years, when serious efforts from a range of private and national entities have explored its possibilities. China may have gotten ahead of the curve with this latest docking, though, in an impressive world first that raises serious concerns for satellites from nations and entities that align themselves differently from China's goals and ambitions.

In January, a satellite designated SJ-25 was launched "for the verification of satellite fuel replenishment and life extension service technologies," according to the Chinese state-owned designer, Shanghai Academy of Spaceflight Technology (via Ars Technica). Sometime last week, it matched orbits with the SJ-21 satellite, which previously conducted space debris maneuvering tests in 2021 and has remained in a geosynchronous orbit ever since.

Last week, the two satellites matched orbits and seemingly docked together. Analysts believe the newer SJ-25 has likely proven refueling is possible even for geosynchronous satellites without the need for a manned crew to facilitate it. In an effort to prove this, two US Space Force's inspector satellites have positioned themselves in closer orbits to SJ-25 and SJ-21 for improved optics. [...] China continues to suggest these missions are part of a debris clean-up program, though it hasn't publicly made any statements about the recent alleged docking and refueling to celebrate its successes. If it doesn't, the only way we'll know if a refueling maneuver was successful is if the SJ-21 satellite unshackles from its younger sibling and performs fuel-demanding maneuvers that its previously estimated fuel levels shouldn't allow for.

Hacker With 'Political Agenda' Stole Data From Columbia, University Says (therecord.media) 28

A politically motivated hacker breached Columbia University's IT systems, stealing vast amounts of sensitive student and employee data -- including admissions decisions and Social Security numbers. The Record reports: The hacker reportedly provided Bloomberg News with 1.6 gigabytes of data they claimed to have stolen from the university, including information from 2.5 million applications going back decades. The stolen data the outlet reviewed reportedly contains details on whether applicants were rejected or accepted, their citizenship status, their university ID numbers and which academic programs they sought admission to. While the hacker's claims have not been independently verified, Bloomberg said it compared data provided by the hacker to that belonging to eight Columbia applicants seeking admission between 2019 and 2024 and found it matched.

The threat actor reportedly told Bloomberg he was seeking information that would indicate whether the university continues to use affirmative action in admissions despite a 2023 Supreme Court decision prohibiting the practice. The hacker told Bloomberg he obtained 460 gigabytes of data in total -- after spending two months targeting and penetrating increasingly privileged layers of the university's servers -- and said he harvested information about financial aid packages, employee pay and at least 1.8 million Social Security numbers belonging to employees, applicants, students and their family members.

Bezos-Backed Methane Tracking Satellite Is Lost In Space (reuters.com) 60

MethaneSAT, an $88 million satellite backed by Jeff Bezos and led by the Environmental Defense Fund to track global methane emissions, has been lost in space after going off course and losing power over Norway. "We're seeing this as a setback, not a failure," Amy Middleton, senior vice president at EDF, told Reuters. "We've made so much progress and so much has been learned that if we hadn't taken this risk, we wouldn't have any of these learnings." Reuters reports: The launch of MethaneSAT in March 2024 was a milestone in a years-long campaign by EDF to hold accountable the more than 120 countries that in 2021 pledged to curb their methane emissions. It also sought to help enforce a further promise from 50 oil and gas companies made at the Dubai COP28 climate summit in December 2023 to eliminate methane and routine gas flaring. [...] While MethaneSAT was not the only project to publish satellite data on methane emissions, its backers said it provided more detail on emissions sources and it partnered with Google to create a publicly-available global map of emissions.

EDF reported the lost satellite to federal agencies including the National Oceanic and Atmospheric Administration, Federal Communications Commission and the U.S. Space Force on Tuesday, it said. Building and launching the satellite cost $88 million, according to the EDF. The organization had received a $100 million grant from the Bezos Earth Fund in 2020 and got other major financial support from Arnold Ventures, the Robertson Foundation and the TED Audacious Project and EDF donors. The project was also partnered with the New Zealand Space Agency. EDF said it had insurance to cover the loss and its engineers were investigating what had happened.

The organization said it would continue to use its resources, including aircraft with methane-detecting spectrometers, to look for methane leaks. It also said it was too early to say whether it would seek to launch another satellite but believed MethaneSAT proved that a highly sensitive instrument "could see total methane emissions, even at low levels, over wide areas."

Laptop Mag Is Shutting Down (theverge.com) 30

Laptop Mag, a tech publication that began in 1991 as a print magazine, is shutting down after nearly 35 years. The Verge reports: Laptop Mag has evolved many times over the years. It started as a print publication in 1991, when Bedford Communications launched the Laptop Buyers Guide and Handbook. Laptop Mag was later acquired by TechMedia Network (which is now called Purch) in 2011 and transitioned to digital-only content in 2013. Future PLC, the publisher that owns brands like PC Gamer, Tom's Guide, and TechRadar, acquired Purch -- and Laptop Mag along with it.

"We are incredibly grateful for your dedication, talent, and contributions to Laptop Mag, and we are committed to supporting you throughout this transition," [Faisal Alani, the global brand director at Laptop Mag owner Future PLC] said. Laptop Mag's shutdown follows the closure of long-running tech site AnandTech, which was also owned by Future PLC. It's not clear whether Laptop Mag's archives will be available following the shutdown.

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks (theverge.com) 10

AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users.

SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features.

FCC Delays Enforcement of Prison Call Pricing Limits (theverge.com) 84

The FCC will suspend enforcement of rules that would lower prison phone and video call prices until April 1st, 2027. Trump-appointed FCC Chair Brendan Carr said that prisons won't have to comply with the pricing regulations [PDF], reversing plans to implement the caps this year.

The rules would have dropped the price of a 15-minute phone call to 90 cents in larger prisons. Current fees can reach as high as $11.35 for a 15-minute call, which the FCC described in 2024 as "exorbitant." Four states -- Connecticut, California, Minnesota, and Massachusetts -- have made prison calls free. Former President Joe Biden signed the Martha Wright-Reed law in 2023, allowing the FCC to regulate prison call rates. The agency voted to adopt the new rates last year, with rules set to take effect on a staggered basis starting January 1st, 2025.

Carr said the regulations are "leading to negative, unintended consequences" and would make caps "too low" to cover "required safety measures." FCC Commissioner Anna Gomez criticized the delay, stating the Commission "is now stalling, shielding a broken system that inflates costs and rewards kickbacks to correctional facilities."

Proton Joins Antitrust Lawsuit Against Apple's App Store Practices (theregister.com) 26

Encrypted communications provider Proton has joined an antitrust lawsuit against Apple, filing a legal complaint that claims the company's App Store practices harm developers, consumers, and privacy. The Switzerland-based firm joined a group of Korean developers who sued Apple in May rather than filing a separate case.

Proton asked the US District Court for Northern California to require Apple to allow alternative app stores, expose those stores through its own App Store, permit developers to disable Apple's in-app payment system, and provide full access to Apple APIs. The company added a privacy-focused argument to typical antitrust complaints, contending that Apple's pricing model particularly penalizes companies that refuse to harvest user data. Developers of free apps typically sell user data to cover costs, while privacy-focused companies like Proton must charge subscriptions for revenue, making Apple's commission cuts more burdensome.

Senate GOP Budget Bill Has Little-Noticed Provision That Could Hurt Your Wi-Fi (arstechnica.com) 62

An anonymous reader shares a report: Sen. Ted Cruz (R-Texas) has a plan for spectrum auctions that could take frequencies away from Wi-Fi and reallocate them for the exclusive use of wireless carriers. The plan would benefit AT&T, which is based in Cruz's home state, along with Verizon and T-Mobile.

Cruz's proposal revives a years-old controversy over whether the entire 6 GHz band should be devoted to Wi-Fi, which can use the large spectrum band for faster speeds than networks that rely solely on the 2.4 and 5 GHz bands. Congress is on the verge of passing legislation that would require spectrum to be auctioned off for full-power, commercially licensed use, and the question is where that spectrum will come from.

When the House of Representatives passed its so-called "One Big Beautiful Bill," it excluded all of the frequencies between 5.925 and 7.125 gigahertz from the planned spectrum auctions. But Cruz's version of the budget reconciliation bill, which is moving quickly toward a final vote, removed the 6 GHz band's protection from spectrum auctions. The Cruz bill is also controversial because it would penalize states that regulate artificial intelligence.

Instead of excluding the 6 GHz band from auctions, Cruz's bill would instead exclude the 7.4-8.4 GHz band used by the military. Under conditions set by the bill, it could be hard for the Commerce Department and Federal Communications Commission to fulfill the Congressional mandate without taking some spectrum away from Wi-Fi.

Sinaloa Cartel Used Phone Data and Surveillance Cameras To Find and Kill FBI Informants in 2018, DOJ Says (aol.com) 36

Designated as a foreign terrorist group by multiple countries, Mexico's Sinaloa drug cartel fiercely defends its transnational organized crime syndicate.

"A hacker working for the Sinaloa drug cartel was able to obtain an FBI official's phone records," reports Reuters, "and use Mexico City's surveillance cameras to help track and kill the agency's informants in 2018, the U.S. Justice Department said in a report issued on Thursday." The incident was disclosed in a Justice Department Inspector General's audit of the FBI's efforts to mitigate the effects of "ubiquitous technical surveillance," a term used to describe the global proliferation of cameras and the thriving trade in vast stores of communications, travel, and location data... The report said the hacker identified an FBI assistant legal attaché at the U.S. Embassy in Mexico City and was able to use the attaché's phone number "to obtain calls made and received, as well as geolocation data."

The report said the hacker also "used Mexico City's camera system to follow the (FBI official) through the city and identify people the (official) met with." The report said "the cartel used that information to intimidate and, in some instances, kill potential sources or cooperating witnesses."

Supreme Court Rejects Challenge To FCC Broadband Subsidy Program (nbcnews.com) 58

The Supreme Court ruled Friday that the FCC's Universal Service Fund can continue operating, rejecting claims that the program's funding mechanism violates the Constitution. In a 6-3 decision written by Justice Elena Kagan, the court found that Congress did not exceed its authority when it enacted the 1996 law establishing the fund and that the FCC could delegate administration to a private corporation. The Universal Service Fund subsidizes telecommunications services for low-income consumers, rural health care providers, schools and libraries through fees generally passed on to customers that raise billions of dollars annually.

The program is administered by the Universal Service Administrative Company, a nonprofit the FCC designated to run the fund. Conservative advocacy group Consumers' Research challenged the structure, arguing that "a private company is taxing Americans in amounts that total billions of dollars every year, under penalty of law, without true governmental accountability."

The Fifth Circuit Court of Appeals ruled in favor of Consumers' Research, prompting the FCC to petition the Supreme Court for review. Kagan wrote that Congress "sufficiently guided and constrained the discretion that it lodged with the FCC to implement the universal-service contribution scheme," adding that the FCC "retained all decision-making authority within that sphere." She concluded that "nothing in those arrangements, either separately or together, violates the Constitution." The challengers argued the program violates the "nondelegation doctrine," a conservative legal theory that says Congress has limited powers to delegate its lawmaking authority to the executive branch.
