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...

We think this reflect the effectiveness of their response strategy. Ugandan mothers used more breastfeeding and tactile comfort at both 3m and 6m, while UK mothers switched to more verbal and engagement strategies as their infants grew. 4/6

Across both sites, faster maternal responsiveness was associated with faster infant recovery from distress, suggesting that prompt maternal intervention facilitates regulation. Although UK mothers were quicker to respond, Ugandan infants actually recovered faster 3/6

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".
