Great apes reassure one another to maintain the peace Our new study shows that friendly touch before stressful events, like embracing, patting and even kissing, promotes tolerance and peace in chimpanzees and bonobos. Some BBC coverage 🙂 open-access paper below! www.bbc.co.uk/news/article...

This is one of the best ideas I've heard in ages.
Reddit post on r/technology about young people and AI: "I recently heard about a teacher who instead of trying to circumvent students using AI, which is impossible, she made assignments by going "ask ChatGPT to write a report on this subject, and then research how and why it's wrong".

Not only did the students discover that ChatGPT is extremely wrong a lot of the time, it also lead them to realise that they should not use it as a primary source".
