One of those jaw-dropping discoveries - although I don't think I'd have let a Neanderthal dentist have got anywhere near mine!

I'd assumed that red light masks probably did nothing to your face and skin. It turns out, they may do too much. Stand out quote: "“We don’t know what’s going to happen in 10 years’ time...Maybe your face is going to drop off.” www.newscientist.com/article/2523...

My colleague Alice Klein writes movingly about how far our understanding of PCOS/PMOS has come. "I find this a much nicer way to think about my ovaries – that they are brimming with eggs, rather than riddled with cysts." www.newscientist.com/article/2526...

I'm doing an AMA on reddit this afternoon about Chornobyl. Decent response so far, but if you have any questions about the site, radiation, nature, whatever, drop a comment. There is no such thing as a stupid question! www.reddit.com/r/chernobyl/...

@sparkes.bsky.social report from Chernobyl is astonishing, revealing how the site has become a one-of-a-kind science experiment, teaching us what radiation does to our health and ecosystems, and what to do the next time there's a major nuclear accident. www.newscientist.com/article/2520...

We are quick to place ourselves on the extremes of the social spectrum, but the truth is that personality is more malleable than you think, says Claudia Canavan

So interesting, especially the gender diagnosis gap, and a second, lesser-known kind of narcissism.
