The northern lights, or aurora borealis, were seen as far south as Cornwall in the UK on Sunday night, and are likely to be visible again on Monday night. Here is how to spot them, says Stargazing at Home columnist Abigail Beall

A bird flu pandemic has killed thousands of wild birds over the last couple of years. Scientists have now seen infection in mammals, and very recently a person died from avian influenza and several close contacts show signs of  infection. The concern is that we might be headed for another H5N1 pandemic. Previous strains of … Continue reading "Avian influenza, bird flu, H5N1"

TL:DR – Thanks to GINA I have not needed to use salbutamol to treat my asthma for three years at the time of writing. It’s three years since my asthma nurse introduced me to GINA, the Global INitiative for Asthma.

Air samples collected around East Palestine, Ohio, continue to show higher-than-normal levels of several hazardous chemicals three weeks after the derailment of a Norfolk Southern freight train, a team of university researchers said Friday.

But the Biden administration said the concentrations of those substances are not high enough to cause concern in the short term — and they will not persist long enough to create long-term health risks after crews remove contaminated soil from the crash site. Читать дальше...
