I feel confident drinking water from lakes, rivers and even the sketchiest of sources with this filtered water bottle -- and that's saying something, because I nearly bit the dust by acquiring three strains of E.

Indoor plant care is always tricky. While it's all fine and dandy to take care of them when the summer sun is shining, keeping your plants alive in winter can feel like a whole ’nother story.

EPA Seeks to Eliminate Critical PFAS Drinking Water Protections

The U.S. Environmental Protection Agency (EPA) announced it will no longer defend rules that protect people from unsafe levels of PFAS “forever chemicals” in drinking water, seeking to reverse legal protections put into place last year. In its motion filed in federal court yesterday, EPA asked the court to axe its determinations to regulate and enforceable standards for four PFAS chemicals – GenX, PFHxS, PFNA, and PFBS.

Scientists Find Evidence of Flowing Water on Giant Asteroid

Today, the near-Earth asteroid known as Ryugu is bone dry. But new research suggests that the half-mile space rock may have once been flowing with liquid water — and crucially, at a period in the solar system's history far later than when that would have been thought possible. The findings, published in a new study in the journal Nature, could add weight to the theory that soggy asteroids brought Earth its first stores of H2O billions of years ago.

An Annual Blast of Pacific Cold Water Did Not Occur, Alarming Scientists

Each year between January and April, a blob of cold water rises from the depths of the Gulf of Panama to the surface, playing an essential role in supporting marine life in the region. But this year, it never arrived. “It came as a surprise,” said Ralf Schiebel, a paleoceanographer at the Max Planck Institute for Chemistry who studies the region. “We’ve never seen something like this before.” The blob is as much as 10 degrees Celsius colder than the surface water.

Scientists Finally ‘See’ a Proton Move Through Water, and It Only Took 200 Years

For over two centuries, scientists have known that water transports a positive charge through protons. But they had never actually seen it happen—until now. In a Science paper published September 11, Yale researchers reported that they devised a method to track, measure, and effectively “see” a proton’s journey through water. For the experiment, the team used a 30-foot-long mass spectrometer—an instrument that separates different elements by mass—that took years to customize and refine. The dev

How can England possibly be running out of water?

news.ycombinator.com Helena Horton 2025-10-04 01:22:35

During the drought of 2022, London came perilously close to running out of water. Water companies and the government prayed desperately for rain as reservoirs ran low and the groundwater was slowly drained off. Contingency plans were drafted to ban businesses from using water; hotel swimming pools would have been drained, ponds allowed to dry up, offices to go uncleaned. If the lack of rainfall had continued for another year, it was possible that taps could have run dry. That, however, was jus

Something Crucial Didn’t Happen in the Gulf of Panama This Year

The Gulf of Panama has experienced an annual wind-driven oceanographic phenomenon called upwelling for at least as long as records of it have existed. In 2025, however, seasonal upwelling failed, and the consequences could be drastic. In a study published Tuesday in the journal PNAS, a Smithsonian Tropical Research Institute-led team suggests that weakening trade winds caused upwelling to fail in the Gulf of Panama this year for the first time in at least four decades.
