New York City's subway system continues to operate largely on analog signal technology installed nearly a century ago, with 85% of the network still relying on mechanical equipment that requires constant human intervention. The outdated system causes approximately 4,000 train delays monthly and represents a technological time capsule in America's largest mass transit system.

Deep inside Brooklyn's Hoyt-Schermerhorn station, transit worker Dyanesha Pryor operates a hulking machine the size of a grand piano by manipulating 24 metal levers that control nearby trains. Each command requires a precise sequence of movements, punctuated by metallic clanking as levers slam into place. When Pryor needs to step away, even for a bathroom break, express service must be rerouted until she returns, forcing all trains onto local tracks.

The antiquated "fixed block" signaling divides tracks into approximately 1,000-foot sections. When a train occupies a block, it cuts off electrical current, providing only a general position rather than precise location data. This imprecision requires maintaining buffer zones between trains, significantly limiting capacity as ridership has grown. Maintenance challenges are also piling up, writes the New York Times. Hundreds of cloth-wrapped wires -- rather than modern rubber insulation -- fill back rooms and are prone to failure. When equipment breaks, replacements often must be custom-made in MTA workshops, as many components have been discontinued for decades.

The Metropolitan Transportation Authority has begun replacing this system with communications-based train control (C.B.T.C.), which uses computers and wireless technology to monitor trains' exact locations. Routes already converted to C.B.T.C., including the L line (2006) and 7 line (2018), consistently show the best on-time performance. However, the $25 million per-mile upgrade program faces uncertain funding after the Trump administration threatened to kill New York's congestion pricing plan, which would provide $3 billion for signal modernization.

An anonymous reader writes: NIH Director Dr. Jay Bhattacharya has announced that the NIH Public Access Policy, originally slated to go into effect on December 31, 2025, will now be effective as of July 1. From Bhattacharya's announcement: NIH is the crown jewel of the American biomedical research system. However, a recent Pew Research Center study shows that only about 25% of Americans have a "great deal of confidence" that scientists are working for the public good. Earlier implementation of the Public Access Policy will help increase public confidence in the research we fund while also ensuring that the investments made by taxpayers produce replicable, reproducible, and generalizable results that benefit all Americans.

Providing speedy public access to NIH-funded results is just one of the ways we are working to earn back the trust of the American people. Trust in science is an essential element in Making America Healthy Again. As such, NIH and its research partners will continue to promote maximum transparency in all that we do.

Carbon removal technologies, potentially a $250 billion market, are failing to gain traction as buyers remain scarce. The Intergovernmental Panel on Climate Change projects a need for 10 billion metric tons of carbon removals annually by 2050, yet only 175 million tons have been sold to date -- less than 2% of requirements.

Microsoft dominates the market, accounting for 35% of all purchases and 76% of engineered removal solutions specifically. The market suffers from significant barriers: unproven technologies, vast price disparities ($80 per ton for forest projects versus $1,000 for direct air capture), and lack of standardization. Industry experts at a recent London gathering concluded that without more buyers willing to accept early adoption risks, the market cannot meaningfully grow.

The Karnataka High Court on Tuesday directed India's government to block Switzerland-based email service Proton Mail, citing national security concerns and law enforcement challenges. Justice M Nagaprasanna ordered authorities to initiate proceedings under Section 69A of the Information Technology Act to ban the service, while mandating immediate blocking of "offending URLs" until final decisions are made.

The ruling followed a petition from M Moser Design Associates India, which claimed its female employees were targeted with obscene emails containing "AI-generated deepfake images" sent via Proton Mail. Petitioners argued Proton Mail operates servers outside India, making it inaccessible to law enforcement. The court noted several bomb threats to Indian schools were sent using the service, which has already been banned in Russia and Saudi Arabia. Additional Solicitor General Aravind Kamath, representing the government, said authorities would comply with the court's direction.

An anonymous reader shares a report: Amazon doesn't want to shoulder the blame for the cost of President Donald Trump's trade war.

So the e-commerce giant will soon show how much Trump's tariffs are adding to the price of each product, according to a person familiar with the plan.

The shopping site will display how much of an item's cost is derived from tariffs -- right next to the product's total listed price. In response, White House press secretary Karoline Leavitt said: This is hostile and political act by Amazon. Why didn't Amazon do this when the Biden administration hiked inflation to the highest level in 40 years? Update: Amazon is considering showing a tariff surcharge on items sold via its site for ultra-low-price items, called Haul, the company said. "This was never a consideration for the main Amazon site and nothing has been implemented on any Amazon properties," the company added.

Indonesian migrant fishermen working in Taiwan's distant-water fishing fleet are trapped in brutal conditions that strip away basic human communication. Sailors spend up to 10 months at sea, working 22-hour days with no internet access, unable to contact families or report workplace hazards. A coalition of labor rights groups, 404 Media, is pushing to mandate Wi-Fi on ships, challenging an industry that intentionally isolates workers and prevents them from seeking help or organizing.

US scientists are fleeing abroad in record numbers as the Trump administration slashes research funding, according to exclusive data analysis by Nature. Applications from American researchers for international positions surged 32% between January and March 2025 compared to the same period last year, while US-based users browsing overseas jobs jumped 35%.

The exodus accelerated in March as the administration intensified science cuts, with job views spiking 68% year-over-year. Applications to Canadian institutions increased 41%, while interest from Canadians in US positions plummeted 13%. Recent months have seen more than 200 federal HIV/AIDS research grants abruptly terminated, cuts to NIH COVID-19 funding revealed, and a $400 million reduction in research grants at Columbia University. "To see this big drop in views and applications to the US -- and the similar rise in those looking to leave -- is unprecedented," said James Richards, who leads Global Talent Solutions at Springer Nature.

European institutions are capitalizing on the talent migration. Aix-Marseille University launched its "Safe Place for Science" initiative with $17.2 million to sponsor researchers, while Germany's Max Planck Society created a Transatlantic Program offering positions to scientists "no longer able to work in the United States." The trend extends beyond Europe, with US-based views of Chinese science positions increasing 30% in the first quarter of 2025.

Major scholarly databases have removed dozens of academic journals after researchers discovered they had been purchased by questionable companies and transformed into predatory publications. A January 2025 study identified 36 legitimate journals acquired by recently formed firms with no publishing experience, who then dramatically increased publication fees and output while lowering quality standards.

According to information scientist Alberto Martin-Martin from the University of Granada, publishers are being offered up to hundreds of thousands of euros per journal title. Once acquired, journals typically introduce or raise article-processing charges while churning out papers often outside the publication's original scope. Scopus has delisted all 36 identified journals, and Web of Science removed 11 of 17 affected titles from its index. "As there has been significant change (different ownership), there is no guarantee that review quality is at the same level as the original journals," an Elsevier spokesperson told Nature.

Despite promises of more efficient streaming, the AV1 video codec hasn't achieved widespread adoption seven years after its 2018 debut, even with backing from tech giants Netflix, Microsoft, Google, Amazon, and Meta. The Alliance for Open Media (AOMedia) claims AV1 is 30% more efficient than standards like HEVC, delivering higher-quality video at lower bandwidth while remaining royalty-free.

Major services including YouTube, Netflix, and Amazon Prime Video have embraced the technology, with Netflix encoding approximately 95% of its content using AV1. However, adoption faces significant hurdles. Many streaming platforms including Max, Peacock, and Paramount Plus haven't implemented AV1, partly due to hardware limitations. Devices require specific decoders to properly support AV1, though recent products from Apple, Nvidia, AMD, and Intel have begun including them. "In order to get its best features, you have to accept a much higher encoding complexity," Larry Pearlstein, associate professor at the College of New Jersey, told The Verge. "But there is also higher decoding complexity, and that is on the consumer end."

An anonymous reader shares a report: A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer, Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data.

Signal president Meredith Whittaker challenged recent assertions by WhatsApp head Will Cathcart that minimal differences exist between the two messaging platforms' privacy protections. "We're amused to see WhatsApp stretching the limits of reality to claim that they are just like Signal," Whittaker said in a statement published Monday, responding to Cathcart's comments to Dutch journalists last week.

While WhatsApp licenses Signal's end-to-end encryption technology, Whittaker said that WhatsApp still collects substantial user metadata, including "location data, contact lists, when they send someone a message, when they stop, what users are in their group chats, their profile picture, and much more." Cathcart had previously stated that WhatsApp doesn't track users' communications or share contact information with other companies, claiming "we strongly believe in private communication."

A software engineer discovered that his newly purchased Bosch 500 series dishwasher locks basic functionality behind cloud connectivity, reigniting concerns about internet-dependent home appliances. Jeff Geerling found that features like rinse cycle, delayed start and eco mode on his $1,000 dishwasher require connecting to WiFi and creating an account with "Home Connect," Bosch's cloud service.

Geerling criticized the approach as potentially part of planned obsolescence, noting that without a current subscription fee, the company will likely either shutter the service or introduce payments for previously standard features.

GIMP 3.0 has been released after over a decade of development. Highlights include a refined GTK3 interface with scroll wheel tab navigation, a new splash screen, improved HiDPI icon support, enhanced color management, a stable public API, and support for more file formats. 9to5Linux reports: GIMP 3.0 also brings improvements to non-destructive editing by introducing an optional "Merge Filters" checkbox at the bottom of NDE filters that merges down the filter immediately after it's committed, along with non-destructive filters on layer groups and the implementation of storing version of filters in GIMP's XCF project files. Among other noteworthy changes, the GEGL and babl components have been updated with new features and many improvements, such as Inner Glow, Bevel, and GEGL Styles filters, some plugins saw small enhancements, and it's now possible to export images with different settings while leaving the original image unchanged.

There's also a new PDB call that allows Script-Fu writers to use labels to specify filter properties, a brand new named-argument syntax, support for loading 16-bits-per-channel LAB PSD files, support for loading DDS images with BC7 support, early-binding CMYK support, and support for PSB and JPEG-XL image formats. On top of that, GIMP 3.0 introduces new auto-expanding layer boundary and snapping options, an updated search pop-up to show the menu path for all entries while making individual filters searchable, a revamped alignment tool, and support for "layer sets," replacing the older concept of linked layers. You can download GIMP 3.0 from the official website.

An anonymous reader quotes a report from TechCrunch: Last week, Google expanded access to its Gemini 2.0 Flash model's image generation feature, which lets the model natively generate and edit image content. It's a powerful capability, by all accounts. But it also appears to have few guardrails. Gemini 2.0 Flash will uncomplainingly create images depicting celebrities and copyrighted characters, and -- as alluded to earlier -- remove watermarks from existing photos.

As several X and Reddit users noted, Gemini 2.0 Flash won't just remove watermarks, but will also attempt to fill in any gaps created by a watermark's deletion. Other AI-powered tools do this, too, but Gemini 2.0 Flash seems to be exceptionally skilled at it -- and free to use. To be clear, Gemini 2.0 Flash's image generation feature is labeled as "experimental" and "not for production use" at the moment, and is only available in Google's developer-facing tools like AI Studio. The model also isn't a perfect watermark remover. Gemini 2.0 Flash appears to struggle with certain semi-transparent watermarks and watermarks that canvas large portions of images.
