Analyst Kurnal Insights calculated that at current AI-driven memory prices, the revenue value of DRAM per square millimeter of silicon now surpasses the nominal wafer processing cost of TSMC's advanced N2 and N3 logic nodes. Using an assumed DRAM price of $1.50 per gigabit, the newest 1b DRAM generation works out to about $0.654 per mm², compared to roughly $0.424 per mm² for an N3 wafer.
Chinese memory maker CXMT has started mass-producing chips built on its new G5 process, which shrinks the DRAM active-area half-pitch to 11.95nm through quadruple-patterning lithography and uses storage capacitors with a 45:1 depth-to-width ratio. The first products, 24Gb LPDDR5X chips offering 50% more capacity than CXMT's prior generation, are already shipping in two package formats and appearing in mainstream Chinese flagship smartphones.
Researchers led by Daolin Tang discovered a novel form of cell death, dubbed alkaliptosis, triggered when a cell's internal pH becomes unusually high rather than through known mechanisms like necrosis or apoptosis. This finding is part of a broader wave of research since 1999 that has expanded the catalog of known cell-death pathways from two classical types to roughly 20 distinct processes, thanks to advances in gene editing, imaging and omics technologies.
Graciela Gómez Hernández, 30, crossed from Tijuana into Southern California on September 14, 2025, hoping to work and support her three children and parents in Mexico. She sent voice messages to family as she hiked through the rugged Otay Mountain Wilderness, but stopped responding by mid-afternoon, saying she could not continue. Her remains were not recovered until two weeks later, despite the area being heavily monitored by border surveillance cameras and technology.
An investigation involving over 45 interviews with officials, Border Patrol agents, medical examiners and tech workers found that Anduril's AI-powered surveillance towers along the US-Mexico border are both failing to detect migrants and, when detections do occur, agents are failing to respond in time. Anduril says CBP operates the towers post-delivery and that surveillance range depends on terrain and privacy-related boundaries CBP itself sets.
A Show HN project called Die With Me packages Claude and Codex API rate-limit notifications into nostalgic AIM-style away messages. Users install a desktop app and use an invitation code to enable the feature, which surfaces usage limit warnings in a retro chat-client format instead of a plain error message.
Pennsylvania's health department confirmed a fourth measles-related death, an unvaccinated 18-year-old from Mifflin County whose death was linked to acute disseminated encephalomyelitis, a rare neurological complication of the disease. Officials also confirmed a coroner's report of an unvaccinated 40-year-old woman's death in Jefferson County, adding to two earlier infant deaths in Lancaster County. The state has now recorded 693 measles cases across 38 counties this year, with 133 hospitalizations.
Jefferson County's coroner reported that a 40-year-old unvaccinated woman died from respiratory failure linked to suspected measles after known exposure to an infected person. She had underlying conditions, including COPD, and relied on supplemental oxygen, which likely worsened her vulnerability to the virus. Her death is the third measles-related fatality in the US this year, all occurring in Pennsylvania.
A volunteer has created a public GitHub mirror and continuation of the freedesktop.org SPICE Windows guest agent project after Red Hat stopped maintaining it. The fork keeps building and packaging the Windows service that enables clipboard sharing, resolution matching, and file transfer for VMs, with fixes like a multi-GPU mouse tracking patch for passthrough setups.
Homebuilders facing a shortage of roughly 1.2 million homes and hundreds of thousands of unfilled construction jobs are turning to robotics, but the real progress is coming from targeted tools like error-checking systems, trade-coordination software, and factory-built modules rather than humanoid robots on job sites. NAHB data shows residential construction productivity has grown just 16% since 1993, far behind the broader economy's 50%-plus gains, while labor shortages cost builders about $11 billion annually and add two months to build times.
AAA reported the national average diesel price reached $6.05 a gallon on Friday, up from $5.85 the prior week and $3.70 a year ago, as the conflict between the U.S. and Iran disrupts global fuel supplies. Regular gasoline also rose to $4.29 a gallon, tracking a jump in both Brent and U.S. crude oil above $100 a barrel for the first time in months.
The national average price for diesel in the United States reached $6.05 per gallon on Friday, according to AAA, marking a more than 60% jump from $3.71 a year earlier. Gasoline also climbed to a national average of $4.29 a gallon, while California diesel prices hit $7.98 a gallon. GasBuddy data confirmed diesel had already exceeded the $6 threshold nationwide.
