EPA Seeks to Eliminate Critical PFAS Drinking Water Protections

news.ycombinator.com Unknown 2025-09-27 12:04:16

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. Separately, EPA previously announced that it will seek to extend the compli

Toxic "forever chemicals" found in 95% of beers tested in the U.S.

news.ycombinator.com Unknown 2025-09-29 05:04:51

Infamous for their environmental persistence and potential links to health conditions, per- and polyfluoroalkyl substances (PFAS), often called forever chemicals, are being discovered in unexpected places, including beer. Researchers publishing in ACS' Environmental Science & Technology tested beers brewed in different areas around the U.S. for these substances. They found that beers produced in parts of the country with known PFAS-contaminated water sources showed the highest levels of forever

Image by Getty / Futurism Studies Some doctors are now advising their pregnant patients to avoid plastic itself, which contains harmful chemicals that can hurt some mothers and babies alike. Marya Zlatnik, a University of California at San Francisco fetal medicine specialist, told the Washington Post that when giving some of her early-pregnancy patients the rundown of what they should and shouldn't consume or be exposed to, she's begun adding plastic products to her no-no list.

It’s Possible to Remove the Forever Chemicals in Drinking Water. Will It Happen?

wired.com Molly Taft 2025-10-12 13:05:14

A new study finds that technologies installed to remove forever chemicals from drinking water are also doing double-duty by removing harmful other materials—including some substances that have been linked to certain types of cancer. The study, published Thursday in the journal ACS ES&T Water, comes as the Trump administration is overhauling a rule mandating that water systems take action to clean up forever chemicals in drinking water.

Generative AI Gave MIT Scientists a New Tool to Fight Antibiotic-Resistant Bacteria

cnet.com See Full Bio 2025-11-13 00:15:43

Antibiotic-resistant bacteria are dangerous because they already "know" what most antibiotics look like. Scientists at MIT have found a way to create something new: using generative AI to design two antibiotic compounds from scratch that can kill drug-resistant gonorrhea and MRSA in lab dishes and mice. Antibiotic resistance is one of the world's biggest public health threats yet new antibiotics have been scarce for decades. Traditional drug discovery methods rely on screening known chemical li

Best Chemical Drain Cleaners of 2025: We Tested 8 to Find the Most Effective Against Your Toughest Clogs

cnet.com See Full Bio 2025-11-27 11:00:00

I leaned on my background as a chemical engineer to offer insights on the effectiveness of these controversial chemicals. In my experiment, I tested eight of the most commonly available chemical drain cleaners: six alkaline and two acidic. I performed dissolution tests to evaluate how well each of them could dissolve drain blockages. I had one goal: to determine which products, if any, would work effectively against the most common clogging materials. 200 ml of Drano Max Gel Gianmarco Chumbe/CN

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. TFA comes mostly from synthetic petrochemicals found in pesticides and landfills, wher

The Next Thing You Smell Could Ruin Your Life

wired.com Lexi Pandell 2026-01-06 10:00:00

After my birth, my mother became allergic to the world. That’s the only way I knew how to put it. So many things could set her off: new carpeting, air fresheners, plastic off-gassing, diesel. Perfumes were among the worst offenders. On top of that, she developed terrible food allergies. The sound of her sniffling became the chorus of my childhood. Some days she couldn’t get out of bed. I’d peek into her darkened room and see her face pinched in discomfort. Her joints ached, her head swam. Docto

Traces of Toxic Industrial Chemical Found in U.S. Air for the First Time

gizmodo.com Ed Cara 2026-03-13 15:10:52

Americans’ air is teeming with all sorts of known toxin pollutants—now scientists have found a new one to add to the list. Researchers at the University of Colorado Boulder detailed their discovery in a study published earlier this month. They sampled agricultural sites in Oklahoma and found clear traces of medium-chain chlorinated paraffins (MCCPs) in the surrounding air. The health effects of MCCPs on people are still being studied, though countries are already planning to debate whether thes
