Sacrebleu! French brewers use algae to make blue beer

A French brewer has started using algae with a naturally-occurring pigment to turn their beer blue. The beer, with the brand name "Line", is the result of a tie-up between a firm that wants to popularise the algae as a dietary supplement, and a nearby craft brewery that was looking for a way to make its beverages more distinctive.

German researchers to breed pigs for human heart transplants this year

German scientists plan to clone and then breed this year genetically modified pigs to serve as heart donors for humans, based on a simpler version of a U.S.-engineered animal used last month in the world's first pig-to-human transplant. Eckhard Wolf, a scientist at Ludwig-Maximilians University (LMU) in Munich, said his team aimed to have the new species, modified from the Auckland Island breed, ready for transplant trials by 2025.

Antarctic fuel-eating microbes may help in plastic clean-up

A team of Argentine scientists is using microorganisms native to Antarctica to clean up pollution from fuels and potentially plastics in the pristine expanses of the white continent. The tiny microbes munch through the waste, creating a naturally occurring cleaning system for pollution caused by diesel that is used as a source of electricity and heat for research bases in the frozen Antarctic.

Alzheimer's-like changes found in COVID patients' brains; flu shot, mRNA booster safe together

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. Alzheimer's-like changes seen in COVID-19 patients' brains
