A Hacker Leaked Data on More Than 41,000 Homeland Security Employees
A hacker obtained and leaked records on more than 41,000 Department of Homeland Security personnel, including staff at ICE and Customs and Border Protection, according to The Verge.

Google Touts a New Gemini 4 Carbon AI Model
Google announced Gemini 4 Carbon, a new version of its frontier AI model that it says delivers “significant gains” in coding, agentic tasks, and cybersecurity, according to The Verge. Google says the model tops the Artificial Analysis Intelligence Index ahead of rivals like Claude Opus 5.5 and GPT-6 Astra, though wide public access isn’t available yet. If you’d rather control which Gemini features show up on your own phone, here’s how to turn off Gemini as your default Android assistant.
A Seven-Piece Eufy Home Security Bundle Drops to $270
Lifehacker flagged a sale on a seven-piece Eufy home security system now priced at $270, according to Lifehacker. The DIY kit stores footage locally and sends smartphone alerts without requiring a monthly subscription. If your current smart home gear tends to cry wolf, you can also stop Ring’s false “someone’s at your door” alerts.

Chrome’s Autofill Can Now Pull Details From Your Gmail
Google rolled out an upgrade to Chrome’s AI-powered autofill that can scan a user’s Gmail inbox for flight confirmations, tracking numbers, and order details to help fill out web forms, according to TechCrunch. The feature is opt-in and is rolling out to desktop users in the US along with the Gemini-in-Chrome mobile apps.
Nvidia Releases a Free Transcription Model for 40 Languages
Nvidia published a free, open-weight transcription model that can convert recorded audio into text across up to 40 languages, according to TechCrunch. It works only on existing recordings rather than live audio, making it a fit for meeting notes and medical transcription rather than real-time captions.

Astronomers Spot a Possible New Dwarf Planet Beyond Neptune
The Vera Rubin Observatory’s Simonyi Survey Telescope turned up a distant object beyond Neptune that could become the solar system’s sixth recognized dwarf planet, according to Space.com. The object has not yet been officially confirmed as a dwarf planet.
Ending Pandemic-Era SNAP Benefits Was Linked to More Child Maltreatment
A new study in the American Journal of Preventive Medicine found that counties which ended COVID-era emergency SNAP food benefits saw an increase in substantiated child maltreatment cases, including neglect and physical abuse, according to Phys.org. Researchers tracked over 1,100 counties across ten states and found the increase built up gradually after benefits ended rather than appearing right away.
PFAS Levels in Drinking Water May Be Roughly Double What’s Reported
A new analysis of nearly 1.86 million EPA water-testing results found that standard reporting methods may understate average PFAS contamination in US drinking water by about half, according to ScienceAlert. The gap comes from how readings below a minimum reporting threshold get counted, and the study doesn’t claim any specific water system is violating federal limits.
An Extra Year of School in the 1970s Linked to Lower Dementia Risk Decades Later
A new study published in PNAS used UK Biobank data to examine a 1972 British law that kept students in school an extra year, finding that those affected had a lower rate of dementia decades later, according to ScienceAlert. The protective effect held even among people with a higher genetic risk for Alzheimer’s disease.
