A man deliberately got 217 Covid shots. Here’s what happened
One German man has redefined “man on a mission.” A 62-year-old from Magdeburg deliberately got 217 Covid-19 vaccine shots in the
The man, who is not named in the correspondence in compliance with German privacy rules, reported receiving 217 Covid shots between June 2021 and November 2023. Of those, 134 were
“This is a really unusual case of someone receiving that many Covid vaccines,
The man did not report any vaccine-related side effects and has not had a Covid infection to date, as
“Perhaps he didn’t get Covid because he was
The researchers also say they do not endorse hypervaccination as a strategy to enhance immunity. “The benefit is not much bigger if you get vaccinated three times or 200 times,” Schober said.
The public prosecutor in Magdeburg opened an investigation into the man for the unauthorized issuing of vaccination cards and forgery of documents but did not end up filing criminal

Does technology replace more jobs than it creates? What is the net balance between these two things? Until now, that has not been measured. But a new research project led by MIT economist David Autor has developed an answer, at least for U.S. history since 1940.The study uses new methods to examine how many jobs have been lost to machine
“There does appear to be a faster rate of automation, and a slower rate of augmentation, in the last four decades, from 1980 to the present, than in the four decades
The study finds that overall, about 60 percent of jobs in the U.S. represent new types of work, which have been created since 1940.To determine this, Autor and his colleagues
From about 1940 through 1980, for instance, jobs like elevator operator and typesetter(排字工人) tended to get automated. But at the same time, more workers —
Ultimately, the research suggests that the negative effects of automation on employment were more than twice as great in the 1980-2018 period as in the 1940-1980 period.There was a more

Using animals to test drugs intended for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary. Statistics indicate that in the UK around three million mice are being used for research and tens of millions worldwide.
Despite the difference in appearances, the genetic similarities with humans are
Animal Defenders International (ADI) is one of the groups that campaigns for an end to the use of animals in research. “We would argue that it is extremely outdated, and not very good science for humans,” says Fleur Dawes of ADI.

Science in Images
Oyster mushrooms feature in cuisines around the world, but they should be off the menu for hungry worms -- which these delicious mushrooms will kill and eat. Now researchers finally know how they do it.
A study published in Science Advances details how oyster mushrooms use a particular poisonous substance to freeze and get rid of mushroom-eating roundworms called nematodes (线虫). The mushrooms, which grow on nutrient-poor dead wood, then
“Nematodes happen to be the most
The study team of geneticists, biochemists and biologists had previously found that oyster mushrooms release an unidentified poisonous substance that will somehow
For their new work, the researchers grew and analyzed samples of the mushroom’s tissue, finding no noticeable poison even when they broke it up. They reasoned that whatever was killing the worms must be a kind of
