Different Science
The results stem from a challenge trial: At the height of the pandemic in 2021, scientists in the United Kingdom exposed 36 young, healthy unvaccinated volunteers who’d never gotten COVID-19 to the virus through their noses (SN: 2/18/21).
The researchers found no significant differences in daily energy intake – as defined by the number of calories consumed per kilogram of the baby’s body weight – at any point between the groups.
It is published by the Society for Science, a nonprofit 501(c)(3) membership organization dedicated to public engagement in scientific research and education (EIN 53-0196483).
A fossil bone displaying features consistent with Down’s syndrome belonged to a Neanderthal child who survived beyond 6 years old, adding to evidence that these extinct humans cared for members of their community
And from Michigan to Mississippi, farmers are scattering volcanic rock dust on their wheat, soy and corn fields with ag spreaders typically reserved for dispersing crushed limestone to adjust soil acidity.
Syntrichia caninervis is widespread in some of Earth’s harshest locations, including Tibet and Antarctica, so Xiaoshuang Li at the Xinjiang Institute of Ecology and Geography in Urumqi, China, and his colleagues decided to subject it to a brutal suite of tests to discover just how much it could survive.

Later, physicists realised that the demon could not break thermodynamic laws “for free” because it would spend energy during its particle selection process, but the idea remained of interest because it can naturally occur in biology and has uses in chemistry.
Flooding from a river shift caused by a similar quake today could threaten up to 170 million people — a number equal to about half the population of the United States — who live in an Illinois-sized area of India and Bangladesh, Chamberlain says.
Its landing and collection manoeuvres relied heavily on autonomous processes and robotic tools, although Chinese engineers could send messages to the spacecraft through the Queqiao-2 relay satellite, which launched in March this year and is still in orbit around the moon.
One heartening example is Innes FitzGerald, a teenage cross-country runner who refused to fly from Britain to Australia for the 2023 World Athletics Championships out of concern for air travel’s carbon emissions (SN: 5/14/20).
Similarly, the new study suggests that if a person standing on Earth’s surface could see the inner core — akin to the bus driver looking at the truck — it would seem to be turning in the opposite direction as it was a couple decades ago.
