Bushfire smoke raised temperatures in Australia by three degrees

British climatologists studied the distribution of smoke in the stratosphere after bushfires in Australia in 2019–2020. They found that black carbon particles in the smoke increased the average temperature in the lower stratosphere by 0.7 degrees worldwide, with temperatures rising by three degrees over Australia. Additionally, the reaction of smoke and ozone has caused the… Continue reading Bushfire smoke raised temperatures in Australia by three degrees

Compression socks protected the intestines of marathon runners from damage

Australian sports doctors, with the participation of fifty runners, studied how compression socks affect the effects of running on the digestive system. After the marathon, those who ran in knee socks had lower levels of a protein marker of small intestinal damage.

Astronomers have found very long radio jets near a nearby active galaxy

Astronomers have discovered two jets of relativistic plasma near the active galaxy NGC 2663, close to the Milky Way, which are characterized by amazing smoothness and enormous length, reaching more than a million light years. For one of them, scientists observed for the first time jet recollimation on a kiloparsec scale, which manifests itself in… Continue reading Astronomers have found very long radio jets near a nearby active galaxy
