A picture is emerging of one of the worst avalanche disasters in US history, and the women among a tight-knit group of friends who died
The ringing of a phone echoed through the Nevada county, California, sheriff’s office just before noon on 17 February.
The 911 call brought devastating news: an avalanche had occurred on nearby Castle Peak – a 9,110ft (2,780-meter) mountain north of the Donner summit in the Lake Tahoe area. A group of backcountry skiers had been on the mountainside, returning home from a three-day expedition, during a heavy winter storm. While six had survived, more than half their group was missing.

An anonymous reader quotes a report from the Guardian: You wear them at work, you wear them at play, you wear them to relax. You may even get sweaty in them at the gym. But an investigation into headphones has found every single pair tested contained substances hazardous to human health, including chemicals that can cause cancer, neurodevelopmental problems and the feminization of males. [...] Researchers say that while individual doses from particular sources may be low, a "cocktail effect" of daily, multi-source exposure nevertheless poses potentially severe long-term risks to health. [...]
Researchers bought 81 pairs of in-ear and over-ear headphones, either on the market in the Czech Republic, Slovakia, Hungary, Slovenia and Austria, or from the online marketplaces Shein and Temu, and took them for laboratory analysis, testing for a range of harmful chemicals. "Hazardous substances were detected in every product tested," they said. Bisphenol A (BPA) appeared in 98% of samples, and its substitute, bisphenol S (BPS), was found in more than three-quarters. Synthetic chemicals used to stiffen plastic, BPA and BPS mimic the action of oestrogen inside organisms, causing a range of adverse effects including the feminization of males, early onset puberty in girls, and cancer. Previous studies have shown that bisphenols can migrate from synthetic materials into sweat, and that they can be absorbed through the skin.
"Given the prolonged skin contact associated with headphone use, dermal exposure represents a relevant pathway, and it is reasonable to assume that similar migration of BPA and its substitutes may occur from headphone components directly to the user's skin," the researchers said. Also found in the headphones tested were phthalates, potent reproductive toxins that can impair fertility; chlorinated paraffins, which have been linked to liver and kidney damage; and brominated and organophosphate flame retardants, which have similar endocrine disrupting properties to bisphenols. Most were, however, found in only trace quantities.
