  • 430,000-Year-Old Wooden Tools Are the Oldest Ever Found
    by msmash on 28/01/2026 at 4:15 pm

    Early hominins in Europe were creating tools from raw materials hundreds of thousands of years before Homo sapiens arrived there, two new studies indicate, pushing back the established time for such activity. From a report: The evidence includes a 500,000-year-old hammer made of elephant or mammoth bone, excavated in southern England, and 430,000-year-old wooden tools found in southern Greece -- the earliest wooden tools on record. The findings suggest that early humans possessed sophisticated technological skills, the researchers said. Katerina Harvati, a paleoanthropologist at the University of Tubingen in Germany and a lead author of the wooden-tool paper, which was published on Monday in the journal PNAS, said the discoveries provided insight into the prehistoric origins of human intelligence. Silvia Bello, a paleoanthropologist at London's Natural History Museum and an author on the elephant-bone study, which was published last week in Science Advances, concurred. The artifacts in both studies, recovered from coal-mine sites, were probably produced by early Neanderthals or a preceding species, Homo heidelbergensis. Homo sapiens emerged in Africa more than 300,000 years ago, and the oldest evidence of them in Europe is a 210,000-year-old fossil unearthed in Greece. By the time Homo sapiens established themselves in Britain 40,000 years ago, other hominins had already lived there for nearly a million years. Read more of this story at Slashdot.

  • 30,000 More UPS Jobs On the Chopping Block as Amazon Era Ends
    by msmash on 28/01/2026 at 3:29 pm

    UPS said today it plans to eliminate an additional 30,000 operational jobs this year as the shipping giant continues to wind down its partnership with Amazon -- previously its largest customer -- and push forward a broader turnaround strategy under CEO Carol Tome. CFO Brian Dykes said on an earnings call that the cuts will be accomplished through attrition and a voluntary separation program for full-time drivers. The company also plans to further deploy automation across its network. UPS has identified 24 buildings for closure in the first half of 2026 and expects to reduce operational hours by approximately 25 million as the Amazon relationship unwinds. Last year, UPS eliminated 48,000 jobs -- 34,000 operational and 14,000 management -- and closed 93 buildings. The company expects $3 billion in total savings from the Amazon unwind.

  • Android's Full Desktop Mode Surfaces in Accidental Chromium Leak
    by msmash on 28/01/2026 at 2:43 pm

    A bug report filed on the Chromium Issue Tracker inadvertently exposed Google's desktop Android interface for the first time, revealing a system codenamed "Aluminum OS" running on existing Chromebook hardware. The report, ostensibly about Chrome Incognito tabs, included screen captures from an HP Elite Dragonfly 13.5 Chromebook running Android 16. The status bar has been redesigned for large screens -- taller than the tablet version, displaying time with seconds, date, battery, Wi-Fi, a notification bell, keyboard language indicator and a Gemini icon. The taskbar remains identical to the current implementation, though the mouse cursor now features a subtle tail. Chrome's interface includes an Extensions button, a feature currently exclusive to the desktop browser. Window controls mirror ChromeOS, placing minimize, fullscreen, and close buttons at the top-right. Read more of this story at Slashdot.

  • Amazon Cuts Another 16,000 Jobs
    by msmash on 28/01/2026 at 2:00 pm

    Amazon announced on Wednesday that it is eliminating approximately 16,000 roles across the company as part of organizational changes that began in October 2025 and are only now being finalized by certain teams. Senior Vice President Beth Galetti shared the news in a memo to employees, framing the reductions as an effort to reduce layers, increase ownership, and remove bureaucracy. The memo follows another memo that the company accidentally sent to employees. Read more of this story at Slashdot.

  • 'Clawdbot' Has AI Techies Buying Mac Minis
    by BeauHD on 28/01/2026 at 1:00 pm

    An open-source AI agent originally called Clawdbot (now renamed Moltbot) is gaining cult popularity among developers for running locally, 24/7, and wiring itself into calendars, messages, and other personal workflows. The hype has gone so far that some users are buying Mac Minis just to host the agent full-time, even as its creator warns that's unnecessary. Business Insider reports: Founded by [creator Peter Steinberger], it's an AI agent that manages "digital life," from emails to home automation. Steinberger previously founded PSPDFKit. In a key distinction from ChatGPT and many other popular AI products, the agent is open source and runs locally on your computer. Users then connect the agent to a messaging app like WhatsApp or Telegram, where they can give it instructions via text. The AI agent was initially named after the "little monster" that appears when you restart Claude Code, Steinberger said on the "Insecure Agents" podcast. He formed the tool around the question: "Why don't I have an agent that can look over my agents?" [...] It runs locally on your computer 24/7. That's led some people to brush off their old laptops. "Installed it experimentally on my old dusty Intel MacBook Pro," one product designer wrote. "That machine finally has a purpose again." Others are buying up Mac Minis, Apple's 5"-by-5" computer, to run the AI. Logan Kilpatrick, a product manager for Google DeepMind, posted: "Mac mini ordered." It could give a sales boost to Apple, some X users have pointed out -- and online searches for "Mac Mini" jumped in the last 4 days in the US, per Google Trends. But Steinberger said buying a new computer just to run the AI isn't necessary. "Please don't buy a Mac Mini," he wrote. "You can deploy this on Amazon's Free Tier."

  • Asteroid 2024 YR4 Has a 4% Chance of Hitting the Moon
    by BeauHD on 28/01/2026 at 10:00 am

    An anonymous reader quotes a report from Universe Today: There's a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen. If Asteroid 2024 YR4 were to hit the Moon, researchers would be able to watch a large lunar impact unfold in real time and collect data on extreme collisions that usually exist only in computer models. Telescopes could follow how a newly formed crater and its pool of molten rock cool and solidify, while the resulting moonquake would offer a clearer picture of its internal structure via the seismic waves it sends through the Moon. Furthermore, researchers could compare the fresh crater to older ones to improve our understanding of the Moon's long history of impacts. Debris blasted off the surface could even deliver small lunar samples to Earth. Altogether, it would be a once-in-a-generation chance to learn more about how the Moon/rocky worlds respond to powerful impacts. Read more of this story at Slashdot.
