Welder’s anthrax, caused by B. cereus–group bacteria with anthrax toxin genes (not classic B. anthracis), has likely been under‑recognized for decades in Gulf Coast welders, underscoring urgent needs for better surveillance and fume controls.

MMWR recently reported a case of welder’s anthrax, a syndrome first described in 1994 and likely under‑recognized as an occupational disease in Gulf Coast metalworkers. Cases of severe pneumonia in we...

When coal is burned to produce electricity, toxic coal ash is left behind. For decades, power companies disposed of coal ash by dumping it into unlined ponds and landfills that leaked toxic chemicals into nearby waters. Coal ash toxins sicken people and kill fish and wildlife.

US employer family #HEALTHCARE #INSURANCE PREMIUMS ROSE 342% SINCE 1999, 3× FASTER THAN WAGES, despite relatively stable utilization trends, driven by rising hospital prices and volatile insurer margins. As insurance costs rise, patients are more likely to delay care or forego insurance.

This economic evaluation describes changes in US workers’ contributions to health insurance premiums and medical costs compared with wages from 1999 to 2024.

COVID-19 mRNA vaccine is safe and effective. An important major French study following 28 million adults aged 18–59 for almost 4 years found that mRNA COVID-19 vaccines DID NOT increase overall deaths. There was ~25% lower overall death risk and 74% lower risk of death from severe COVID‑19.
Enormous New Study Finds COVID-19 mRNA Shots Associated With 25 Percent Lower Risk Of Death From Any Cause
Even supporters of mRNA vaccination against COVID-19 might be surprised at just how much higher death rates are among the unvaccinated.

Researchers at University of Hong Kong have developed “e-skin” (NRE-skin) for robots to feel touch, detect damage, and trigger fast reflex “pain” responses via neural‑style spikes, enabling them to manage their own safety and interaction risk in real time.

“Blood thinners”
Anticoagulants don’t “thin” the blood—they reduce clot formation. The phrase comes from bloodletting and use of leeches. It is an entrenched, though incorrect, misleading, and outdated, lay metaphor. Learn more:

Have high BP? Hypertension is poorly controlled in the US. A new AHA statement recommends most adults with hypertension should start on single‑pill combination therapy, not traditional stepped‑care monotherapy. SPC is more effective, speeds BP control, and improves adherence.

Subtype‑specific, precision medicine approaches will be needed instead of one‑size‑fits‑all care. News item: www.autismspeaks.org/science-news...

A paper published in Nature in September suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.
