Damn it ! French brewers use algae to make blue beer
A French brewer has started using seaweed with a natural pigment to make its beer blue. The beer, with the brand name “Line”, is the result of a merger between a company that wants to popularize seaweed as a dietary supplement, and a neighboring craft brewery that was looking for a way to make its drinks more distinctive. .
Hitchhiking in Earth’s orbit, an asteroid could accompany us for 4,000 years
An asteroid that has been discovered circulating in Earth’s orbit is about 1.2 km wide and could hitchhike with our planet for at least 4,000 more years without posing any danger, scientists said on Tuesday. Using observations from telescopes in Chile, Arizona and the Canary Islands, researchers have provided the most comprehensive description yet of the asteroid, named 2020 XL5 and first detected two years ago. They confirmed that it was one of only two Trojan asteroids traveling companion to Earth.
German researchers will breed pigs for human heart transplants this year
German scientists plan to clone and then breed genetically modified pigs this year to serve as heart donors for humans, based on a simpler version of a US-engineered animal used last month in the first pig transplant to man in the world. Eckhard Wolf, a scientist at the Ludwig-Maximilians University (LMU) in Munich, said his team aimed to have the new species, modified from the Auckland Island race, ready for testing. transplantation by 2025.
The placenta may have a mechanism that protects the fetus from COVID; safe vaccines for rheumatic diseases
Here is a summary of some recent studies on COVID-19. They include research that deserves further study to corroborate the findings and that has not yet been certified by peer review. The placenta can excrete proteins to prevent the virus from entering
The deployment of NASA’s new moon rocket to the launch pad has been delayed by at least a month
The long-awaited deployment of NASA’s big new moon rocket to its launch pad in Florida for final testing before a first flight has been delayed by at least a month, until March at the earliest, the report said on Wednesday. US space agency. NASA, which late last year had targeted liftoff this month for its uncrewed Artemis 1 mission around the moon and back, declined to set a revised launch date, but the delay would prevent a flight before April.
Farmers test microbes to feed crops as climate pressure mounts and costs rise
Tech companies are raising hundreds of millions of dollars, including leaning on agricultural heavyweights like Bayer AG, to develop agricultural products that use living things like microbes and algae to feed crops and reduce the need for synthetic fertilizers. Microbes, including fungi and viruses, have been available for decades as treatments to protect plants against insects and disease, with mixed results. But developers are increasingly deploying them as natural ways to nurture crops while maintaining crop production levels.
