Phys.org / PFAS exposure greater in wet pet food, study suggests
Ehime University investigators measured 34 per- and polyfluoroalkyl substances in 100 commercial dog and cat foods sold in Japan and detected PFAS across many products, with higher concentrations in fish-based foods and dry ...
Phys.org / Missing methane: Countries may be underestimating wastewater greenhouse gas emissions
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant ...
Medical Xpress / HIV can develop resistance to blockbuster antiviral lenacapavir—but at a cost to the virus
Long-acting antiviral medications are transforming HIV prevention and care, requiring only minimalistic dosing. But as the use of lenacapavir expands, scientists are probing a critical question: If the virus evolves resistance, ...
Medical Xpress / Brain scans reveal why you can't resist a snack, even when you're full
Research from the University of East Anglia (UEA) may finally explain why we still reach for the cookie jar, even when we're full. A new study reveals that the human brain continues to respond to tempting food cues even after ...
