news.ycombinator.com Unknown 2025-12-16 11:49:34

New findings from studying over two decades of satellite observations reveal that the Earth’s continents have experienced unprecedented freshwater loss since 2002, driven by climate change, unsustainable groundwater use and extreme droughts. The study, led by Arizona State University and published today in Science Advances, highlights the emergence of four continental-scale “mega-drying” regions, all located in the Northern Hemisphere, and warns of severe consequences for water security, agricu

futurism.com Unknown 2025-12-16 11:30:37

Scientists were caught by surprise after discovering a massive flood of subglacial lakewater burst through Greenland's ice sheet, spilling copious amounts of water across its surface. As detailed in a new paper published in the journal Nature Geoscience, it's the first time such a phenomenon has been observed, highlighting the fierce power being stored in meltwater lurking beneath a thick sheet of ice. The event also defies our predictions of how the Greenland ice sheet evolves over time, even

Almost All Rain Drops Contain the Same Weird Chemical

Since the rise of commercial chemical manufacturing in the 1940s, the environment has been plagued by a growing concentration of man-made substances like microplastics, PCBs, and bisphenols. There's even a new one rising to prominence: the chemical compound trifluoroacetic acid, or TFA. New reporting by Nature detailed the troubling rise of TFA and its inexorable creep into every corner of the natural world.

The second-gen Apple Watch is now ‘obsolete’, but don’t get confused

9to5mac.com Marcus Mendes 2025-12-16 12:05:08

Five years after Apple stops selling a product, it may become ‘vintage’, meaning Apple will still repair it. Five years after that, it can become ‘obsolete,’ and Apple no longer offers hardware service or parts. Today’s that day for the Apple Watch Series 1. Here’s what that means Wait, is it the Series 1, or the 2nd-gen Apple Watch? In a nutshell, both. They’re the same picture device.

Joe Maring / Android Authority TL;DR Identity Check offers an extra layer of protection when someone steals both your phone and your PIN. By requiring biometrics, Identity Check attempts to limit the harm bad actors could do. Google is working to let you bypass that biometric requirement when your device is connected to a trusted smartwatch.

Gemini Will Overshadow the Best Upgrades to Google’s New Pixel Buds and Pixel Watch

gizmodo.com Raymond Wong 2025-12-18 03:09:36

My gut tells me that Google is going to use its Pixel devices launch event on August 20 to talk a lot about AI—specifically Gemini and how it’ll be woven into the Android-powered devices in a deep way. Google so poorly safeguarded the reveal of its entire Pixel hardware lineup that it only makes sense for the company to focus its upcoming event on AI rather than the gadgets themselves.
