The latest science news, in brief.
The team looked at 57 children with a median age of 4 and 51 adults with a median age of 37, who tested positive for SARS-CoV-2 in late 2020. They found that children and adults had similar viral loads, but, compared with 76% of the adults. The findings were published on 9 March.
Children could also be better at responding to infections where they enter the body. This means that the body clears the virus quickly and it doesn’t “hang around” to trigger antibody production, says Donna Farber, an immunologist at Columbia University in New York City. The booster is probably part of a rocket that launched a small Chinese spacecraft, called Chang’e 5-T1, towards the Moon in 2014. Although Chang’e 5-T1 returned to Earth successfully, the booster is thought to have been zipping around chaotically in space ever since. Lunar gravity pulled it into a fatal collision with the far side of the Moon.
