PETROPAVOVSK-KAMCHATSKY, Russia (AP) — One of Russia’s most active volcanoes has erupted, spewing plumes of ash 5 kilometers (3 miles) into the sky over the far eastern Kamchatka Peninsula and briefly triggering a “code red” warning for aircraft.

The Shiveluch volcano began sputtering shortly after a powerful 7.0 magnitude earthquake struck off Kamchatka’s east coast early Sunday, according to volcanologists from the Russian Academy of Sciences. They warned that another, even more potent earthquake may be on the way.

The academy’s Institute of Volcanology and Seismology released a video showing the ash cloud over Shiveluch. It stretched over 490 kilometers (304 miles) east and southeast of the volcano.

Not in leading research but interesting.


According to a new study, a polyphenol-rich natural extract positively impacts lifespan, healthspan, and cellular senescence. These results were observed in both cell culture and a mouse model [1].

Traditional and folk medicines offer many botanical extracts that can be tested by modern science for their medicinal properties and influences on aging. One such plant is the Bolivian prawn sage (Salvia haenkei).

An ischemic stroke is a type of stroke that occurs when a blood clot in an artery, also known as thrombus, or the progressive narrowing of arteries, blocks the blood and oxygen flowing to the brain. This process can cause both temporary and permanent brain damage, for instance, leading to partial paralysis, cognitive impairments and other debilitating impairments.

Statistics suggest that older age increases the risk of experiencing ischemic strokes. While neuroscience studies have shed light on many of the physiological processes underpinning strokes, the immune responses following these events and promoting recovery remain poorly understood.

Researchers at the Institut Blood and Brain @ Caen-Normandie (BB@C), University of Edinburgh and other institutes in Europe carried out a study exploring how central nervous system (CNS)-associated macrophages (CAMs), immune cells residing at the CNS interfaces, contribute to post-stroke immune responses.
