Spatial methods for identifying unusual accumulations at Paleolithic sites

A collaboration between researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) and the Human Evolution Research Center (HERC) of the University of California at Berkeley has allowed a study to be published in the Journal of Archaeological Method and Theory, which reviews the traditional and more innovative methods for identifying unusual horizontal concentrations...

My belly is angry, my throat is in love: Body parts and emotions in Indigenous languages

Many languages in the world allude to body parts to describe emotions and feelings, as in "broken-heart," for instance. While some have just a few expressions like this, Australian Indigenous languages tend use a lot of them, covering many parts of the body: from "flowing belly" for "feel good" to "burning throat" for "be angry" to "staggering liver" meaning "to mourn."

Large collaboration creates cell atlas of COVID-19 pathology

Scientists from several hospitals and research centers have shown what happens in individual cells of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes. They also saw signs of multiple, unsuccessful attempts of the lungs to repair themselves in response to respiratory...

Research shows long-term recovery possible for areas impacted by seagrass die-off

Nearly 10,000 acres of lush seagrass vanished from Florida Bay between 1987 and 1991, leading to massive ecological changes in the region near the Florida Keys. Abundance of the seagrass, Thalassia testudinum, more commonly known as turtlegrass, a foundation species of the Florida Bay ecosystem, decreased extensively during what is considered to be one of the largest declines in seagrass cover in...

An economical alloy-based aerogel as electrocatalyst for carbon fixation

Many industrial processes emit carbon dioxide into the atmosphere. Unfortunately, however, current electrochemical separation methods are expensive and consume large amounts of power. They also require expensive and rare metals as catalysts. A study in the journal Angewandte Chemie describes a new aerogel electrocatalyst formed from an inexpensive metal alloy, which enables highly efficient...

Figures on Covid deaths post-jab show vaccine’s success, scientists say

Small number have died after being vaccinated, mostly having caught virus before dose could take effectA small number of people vaccinated against Covid have been admitted to hospital with the disease and died, researchers have found, but most were frail and elderly and caught the virus before the jab could have taken effect.Scientists say their findings are reassuring. They bear out the...
