Post-COVID condition is not linked to ongoing infection or active brain damage

A recent study by the University of Gothenburg found no correlation between post-COVID condition and ongoing viral infection or active brain damage. The study analyzed 25 participants with confirmed post-COVID condition, six without residual symptoms, and 17 control subjects, revealing undetectable SARS-CoV-2 antigens in all samples.

Convalescent plasma reduces mortality by 10% in COVID-19 patients in acute respiratory distress and on artificial respiratory assistance

A study published in The New England Journal of Medicine found that convalescent plasma administration reduced mortality by 10% in COVID-19 patients with acute respiratory distress requiring artificial mechanical ventilation. The reduction was most pronounced when plasma was administered within the first 48 hours after initiation of ve...

Acquiring green firms can be healthy for a firm’s bottom line, says new Concordia research

Researchers found that shareholders generally welcomed news of green acquisitions, especially when buyers have developed marketing expertise. They also discovered that benefits are buffered if buyers belong to industries sensitive to environmental regulations. This suggests investors can tell genuine from fake green efforts.

How eggs of the Zika-carrying mosquito survive desiccation

A new study reveals that mosquito eggs can tolerate extended desiccation by changing their metabolic pathway. By rewiring their polyamine and lipid metabolism, the eggs become more resistant to dehydration. This finding provides potential new ways to control the spread of Zika virus.

Home is where the high-quality resources are: nursery characteristics and territory distribution suggest reproductive resource defense in golden rocket frogs

Researchers found that male golden rocket frogs choose to defend bromeliad pools with lower mucilage levels, which improves tadpole survival. This suggests a reproductive resource defense strategy where males prioritize their future offspring's success by securing high-quality nurseries.

Raining cats and dogs: research finds global precipitation patterns a driver for animal diversity

A study published in Ecology Letters reveals that global precipitation patterns, particularly seasonal variability, shape animal diversity. The research found that certain regions with moderate precipitation levels and stable climates have the ideal ecological conditions for a diverse range of predators and herbivores.

How quantum light sees quantum sound

Researchers at UEA have proposed a new method to investigate quantum-mechanical processes in molecules using quantum light. The study shows that phonon signatures can be detected in photon correlations, providing a toolbox for studying quantum sound interactions.

When family members of patients with colorectal cancer are invited to screening appointments themselves, just 1 in 3 go ahead with either fecal testing or colonoscopy, representing missed opportunities for early detection

A clinical trial in Spain found that only 1 in 3 family members of patients with colorectal cancer participate in screening, missing opportunities for early detection. The study used fecal testing and colonoscopy to screen first-degree relatives, but uptake was low.
