Amazon appears to have prematurely acknowledged layoffs inside AWS after an internal email referencing "organizational changes" and "impacted colleagues" was mistakenly sent to cloud employees. CNBC reports: "Changes like this are hard on everyone," Colleen Aubrey, senior vice president of applied AI solutions at Amazon Web Services, wrote in an email viewed by CNBC. "These decisions are difficult and are made thoughtfully as we position our organization and AWS for future success." The note also references a post from Amazon's HR boss Beth Galetti and said the company notified "impacted colleagues in our organization." The subject of the email mentions "Project Dawn," and the email says it was "canceled," possibly indicating it was recalled by the sender after the fact. It's unclear what Project Dawn refers to. The job cuts come after Amazon announced in October that it would lay off 14,000 corporate employees. At the time, the company indicated the cuts would continue in 2026 as it found "additional places we can remove layers." Amazon CEO Andy Jassy said the layoffs were meant to reduce management layers and bureaucracy inside the company. He also predicted last June that efficiency gains from AI would shrink Amazon's corporate staff in the coming years.

An anonymous reader quotes a report from Science.org: Some 10,109 doctoral-trained experts in science and related fields left their jobs last year as President Donald Trump dramatically shrank the overall federal workforce. That exodus was only 3% of the 335,192 federal workers who exited last year but represents 14% of the total number of Ph.D.s in science, technology, engineering, and math (STEM) or health fields employed at the end of 2024 as then-President Joe Biden prepared to leave office. The numbers come from employment data posted earlier this month by the White House Office of Personnel Management (OPM). At 14 research agencies Science examined in detail, departures outnumbered new hires last year by a ratio of 11 to one, resulting in a net loss of 4224 STEM Ph.D.s. The graphs that follow show the impact is particularly striking at such scientist-rich agencies as the National Science Foundation (NSF). But across the government, these departing Ph.D.s took with them a wealth of subject matter expertise and knowledge about how the agencies operate. [...] Science's analysis found that reductions in force, or RIFs, accounted for relatively few departures in 2025. Only at the Centers for Disease Control and Prevention, where 16% of the 519 STEM Ph.D.s who left last year got pink RIF slips, did the percentage exceed 6%, and some agencies reported no STEM Ph.D. RIFs in 2025. At most agencies, the most common reasons for departures were retirements and quitting. Although OPM classifies many of these as voluntary, outside forces including the fear of being fired, the lure of buyout offers, or a profound disagreement with Trump policies, likely influenced many decisions to leave. Many Ph.D.s departed because their position was terminated.

Apple quietly released its first update to iOS 12 since 2023 to keep iMessage, FaceTime, and device activation working on older hardware through January 2027. The update applies to legacy devices like the iPhone 5S, iPhone 6/6 Plus, and 2013-era iPads. Macworld reports: The update appears to be related to a specific issue. According to Apple's "About iOS 12 Updates" page, iOS 12.5.78 "extends the certificate required by features such as iMessage, FaceTime, and device activation to continue working after January 2027." Meanwhile, the iOS 16 update says it "provides important bug fixes and is recommended for all users." When iOS 13 arrived, it dropped compatibility for the iPhone 5S, iPhone 6, and iPhone 6 Plus, as well as the 2013 iPad Air and iPad Mini 3, so users of those phones should specifically take note. To update to the latest version, head over to the Settings app, then General and Software Update, and follow the instructions.

Scientists have released DinoTracker, a free AI-powered app that identifies dinosaur footprints by analyzing shape patterns rather than relying on potentially flawed historical labels. "When we find a dinosaur footprint, we try to do the Cinderella thing and find the foot that matches the slipper," said Prof Steve Brusatte, a co-author of the work. "But it's not so simple, because the shape of a dinosaur footprint depends not only on the shape of the dinosaur's foot but also the type of sand or mud it was walking through, and the motion of its foot." The Guardian reports: [...] Brusatte, [Dr Gregor Hartmann, the first author of the new research from Helmholtz-Zentrum in Germany] and colleagues fed their AI system with 2,000 unlabelled footprint silhouettes. The system then determined how similar or different the imprints were from each other by analysing a range of features it identified as meaningful. The researchers discovered these eight features reflected variations in the imprints' shapes, such as the spread of the toes, amount of ground contact and heel position. The team have turned the system into a free app called DinoTracker that allows users to upload the silhouette of a footprint, explore the seven other footprints most similar to it and manipulate the footprint to see how varying the eight features can affect which other footprints are deemed most similar. Hartmann said that at present experts had to double check if factors such as the material the footprints were made in, and their age, matched the scientific hypothesis, but the system clustered prints with those expected from classifications made by human experts about 90% of the time. The findings have been published in the journal PNAS.
