Aren't the studies with mice supposed to be done before the humans ingest it?

Reply to China's manufacturing activity contracted sharply in December for the third month in a row, according to official figures released Saturday, despite Beijing's loosening of Covid restrictions at the beginning of the month by DoremusJessup

>Cumulative deaths in China since 1 December likely reached 100,000, with infections totalling 18.6m, Airfinity said in a statement on Thursday. It used modelling based on data from Chinese provinces before the recent changes to reporting cases were implemented, it said.

>Airfinity expects deaths to peak on 23 January with about 25,000 a day, with cumulative deaths reaching 584,000 since December. Since 7 December, when China made its abrupt policy U-turn, authorities have officially reported just 10 Covid deaths.
Due to the fear of new variants coming from China to other countries (only the same variants are being found so far), the US is considering testing aircraft wastewater:

>After decades of work, the only approved malaria vaccine, Mosquirix, made by British drugmaker GSK (GSK.L), was this year endorsed by the World Health Organization (WHO), but a lack of funding and commercial potential has thwarted GSK's capacity to produce as many doses as needed.

Reply to The mRNA vaccine technology successfully used for COVID has been adapted to fight malaria, a disease that killed over 625,000 people in 2020. In a research study on mice, two mRNA vaccines were highly effective in reducing infection in the host and in the mosquito vector. by grab-n-g0

>A research team led by George Washington University has developed two mRNA vaccine candidates that are highly effective in reducing both malaria infection and transmission.

>“These vaccines were highly effective at preventing infection and they wiped out transmission potential almost entirely,” said Nirbhay Kumar, a professor of global health at the George Washington University Milken Institute School of Public Health.

>To see how the mRNA vaccines stacked up against other nucleic acid -based vaccine platforms, Kumar and the team repeated the experiment using DNA plasmids. The mRNA vaccines were far superior in inducing an immune response compared to the DNA-based vaccines, they found.

You could always look up 'rewilding' and educate yourself. Or, just go up against the conservation officer at Wildwood Trust and pretend you know more.

Article is about restoring wild habitat in UK, not another species in USA.
>Populations of the UK’s most important wildlife have plummeted by an average of 60% since 1970 and Britain is one of the most nature-depleted countries in the world. The project [assesses] how bison act as “ecosystem engineers” to restore wild habitat.
>
>Bison’s taste for bark kills some trees and their bulk opens up trails, letting light spill on to the forest floor, while their love of rolling around in dust baths creates more open ground for new plants, invertebrates and birds. The Wilder Blean project aims to naturally regenerate a former pine wood plantation.
>
>The process has been surprisingly speedy, said Gibbs, who has seen slow worms basking and heard more birdsong. “We had not seen dung beetles on the site but all of a sudden, they are just thriving,” he added.
>
>Vicki Breakell, conservation officer at the Wildwood Trust, said: “They’ve created tracks and pathways, which has opened up the canopy already, and they’ve been munching on the bark, which over time is going to create the standing dead wood which is so valuable for a whole host of different species.”

>The bison are currently in a five-hectare (12-acre) enclosure, as they adapt to their new lives and their health is closely monitored. They will be moved to an area of 50-hectare (124 acres) next and then, next summer, the full 200-hectare site (494 acres).
Ehm, rewilding is the goal.

Probably not, but biologists do give a special name to the first shit a baby bison takes because it stinks so much: a worsel.
Most of them only rate 111 to 222 on the stinkometer but this one came out at a 555.

Bison Ranger Gibbs (the job title to get):
