  • Apple's Touch-Screen MacBook Pro To Have Dynamic Island, New Interface
    by msmash on 25/02/2026 at 8:00 am

    Apple's forthcoming touch-screen MacBook Pro models -- the company's first-ever laptops to support touch input -- will feature the iPhone's Dynamic Island at the center top of their OLED displays and a new interface that dynamically adjusts between touch and point-and-click controls, according to a Bloomberg report citing people familiar with the plans. The 14-inch and 16-inch models, code-named K114 and K116, are slated for release toward the end of 2026 and won't be part of Apple's product announcements in the first week of March. The redesigned interface brings up a contextual menu surrounding a user's finger when they touch a button or control, and enlarges menu bar items when tapped, adapting the available controls based on whether the input is touch or click. Apple does not plan to position the machines as iPad replacements or describe them as touch-first; the physical design retains the full keyboard and large trackpad of the current MacBook Pro. Last year's Liquid Glass redesign in macOS Tahoe, which added more padding around icons and touch-optimized sliders in the control center, was partly groundwork for this shift.

  • The US Had a Big Battery Boom Last Year
    by msmash on 25/02/2026 at 4:01 am

    The United States installed a record 57 gigawatt hours of new battery storage on its electric grids in 2025, a nearly 30% increase over the prior year that arrived even as the Trump administration cut tax credits for wind and solar in last summer's One Big Beautiful Bill. The figures come from a Solar Energy Industries Association report published Monday, which also projects the market will grow another 21% this year by adding 70 gigawatt hours in 2026 alone. Battery tax credits themselves survived the legislation largely intact, and the majority of last year's new installations were stand-alone systems not tied to specific solar projects. In Texas, solar met more than 15% of electricity demand throughout the summer and beat out coal for the first time, and the SEIA report predicts the state will overtake California this year in total deployed storage. Supply chain restrictions reinforced by the bill and project cancellations could slow the pipeline this year, the report cautions. Read more of this story at Slashdot.

  • First British Baby Born Using Transplanted Womb From Dead Donor
    by msmash on 25/02/2026 at 1:30 am

    A 10-week-old boy named Hugo has become the first baby born in the UK from a womb transplanted from a deceased donor, after his mother Grace Bell -- who was born without a viable womb due to a condition called MRKH syndrome, which affects one in every 5,000 women -- underwent a 10-hour transplant operation at The Churchill Hospital in Oxford in June 2024. Hugo was born just before Christmas 2025, weighing nearly 7lbs, at Queen Charlotte's and Chelsea Hospital in west London, following IVF treatment and embryo transfer at The Lister Fertility Clinic. Bell's transplant is one of three completed so far as part of a UK clinical research trial that plans to carry out 10 such procedures from deceased donors, and Hugo is the first baby born from any of them. Earlier in 2025, a separate effort produced baby Amy, the first UK birth from a living womb donation -- her mother had received her older sister's womb in January 2023. Globally, more than 100 womb transplants have been performed, resulting in over 70 healthy births. Read more of this story at Slashdot.

  • Meta AI Security Researcher Said an OpenClaw Agent Ran Amok on Her Inbox
    by msmash on 24/02/2026 at 10:30 pm

    Meta AI security researcher Summer Yue posted a now-viral account on X describing how an OpenClaw agent she had tasked with sorting through her overstuffed email inbox went rogue, deleting messages in what she called a "speed run" while ignoring her repeated commands from her phone to stop. "I had to RUN to my Mac mini like I was defusing a bomb," Yue wrote, sharing screenshots of the ignored stop prompts as proof. Yue said she had previously tested the agent on a smaller "toy" inbox where it performed well enough to earn her trust, so she let it loose on the real thing. She believes the larger volume of data triggered compaction -- a process where the context window grows too large and the agent begins summarizing and compressing its running instructions, potentially dropping ones the user considers critical. The agent may have reverted to its earlier toy-inbox behavior and skipped her last prompt telling it not to act. OpenClaw is an open-source AI agent designed to run as a personal assistant on local hardware. Read more of this story at Slashdot.

  • New Datacentres Risk Doubling Great Britain's Electricity Use, Regulator Says
    by msmash on 24/02/2026 at 9:00 pm

    The amount of power being sought by new datacentre projects in Great Britain would exceed the national current peak electricity consumption, according to an industry watchdog. From a report: Ofgem said about 140 proposed datacentre schemes, driven by use of artificial intelligence, could require 50 gigawatts of electricity -- 5GW more than the country's current peak demand. The figure was revealed in an Ofgem consultation on demand for new connections to the power grid. It pointed to a "surge in demand" for connection applications between November 2024 and June last year, with a significant number coming from datacentres. This has exceeded even the most ambitious forecasts. Meanwhile, new renewable energy projects are not being connected to the grid at the pace they are being built to help meet the government's clean energy targets by the end of the decade. Ofgem said the work required to connect surging numbers of datacentres could mean delays for other projects that are "critical for decarbonisation and economic growth." Datacentres are the central nervous system of AI tools such as chatbots and image generators, playing a vital role in training and operating products such as ChatGPT and Gemini.

  • CrowdStrike Says Attackers Are Moving Through Networks in Under 30 Minutes
    by msmash on 24/02/2026 at 8:00 pm

    An anonymous reader shares a report: Cyberattacks reached victims faster and came from a wider range of threat groups than ever last year, CrowdStrike said in its annual global threat report released Tuesday, adding that cybercriminals and nation-states increasingly relied on predictable tactics to evade detection by exploiting trusted systems. The average breakout time -- how long it took financially-motivated attackers to move from initial intrusion to other network systems -- dropped to 29 minutes in 2025, a 65% increase in speed from the year prior. "The fastest breakout time a year ago was 51 seconds. This year it's 27 seconds," Adam Meyers, head of counter adversary operations at CrowdStrike, told CyberScoop. Defenders are falling behind because attackers are refining their techniques, using social engineering to access high-privilege systems faster and move through victims' cloud infrastructure undetected.
