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.
Our warming world is partly responsible for increasing rates of AMR, with shifting climate conditions around the globe helping bacteria such as Salmonella and cholera-causingVibrio to survive – and evade our current antibiotic weaponry completely.

As the climate warms, the future of Antarctica’s vast ice sheets remains uncertain, with projections ranging widely for how rapidly they will melt and therefore how much they will contribute to sea level rise.
For instance, the first cellular changes that signal the start of a cancer may be only subtly different — as in small and hard to distinguish from nearby healthy tissues.
