Episode 304 It seems the world is on heightened alert about the impact smartphones are having on our children’s brains. But are we right to be worried? Jonathan Haidt’s book the Anxious Generation has played a big role in this debate, with many researchers agreeing smartphones cause harm and action needs to be taken. But is there actually any scientific evidence to back all of these claims up? The “strongest evidence” for alien life was announced just a few weeks ago - but not everyone was happy with this discovery and it came under quite a lot of fire. The team that discovered this alien signal were analysing data from the James Webb Space Telescope. Now other researchers have looked at the same data and have come to different conclusions. But rather than proving critics right, it seems the evidence for aliens just got stronger. A digital oak tree is on display at Kew Gardens in London. Of the Oak is an immersive installation by art collective Marshmallow Laser Feast in collaboration with ecologists, biologists and researchers. The aim is to show the inner workings of the oak, to allow people to connect more deeply with it and to tune into “tree time”. Chapters: (00:32) Are smartphones causing mental illness in teens?
