Extreme rainfall – A long-standing hypothesis on temperature dependence finally settled?

A new study finds that the Clausius-Clapeyron relation explains almost perfectly selected thunderstorm rainfall data at each temperature, but when combining both stratiform and thunderstorm rainfall, higher temperature increase rates emerge. The authors argue that this 'super-Clausius-Clapeyron' increase is of statistical origin, settl...

AI suggestions make writing more generic, Western

A study by Cornell University finds that AI-based writing assistants can generate generic language that makes non-Western users write in a more American style, leading to cultural stereotyping and language homogenization. Indian participants showed a smaller productivity boost compared to their American counterparts.

Rats are more motivated to help their friends

Researchers found that rats are more likely to aid distressed peers if they have previous positive social interactions with them. Helper rats showed increased activity in brain regions associated with empathy and motivation compared to less helpful rats. Oxytocin signaling may play a role in motivating rats to care for others.
