A remarkable view of pregnancy; how to waste less time on your smartphone; superacid diamond rain

Episode 295

The changes the body goes through during and after pregnancy have been examined in more detail than ever before. A landmark study is finally helping us to piece together some of the mysteries and myths surrounding this time – from how long it takes the body to go back to “normal” after birth to the extended periods of nutrient deficiency. This comes after a flurry of studies have given us the clearest picture yet of how the brain changes – and is dramatically remodelled – throughout pregnancy.

Are you worried about your smartphone habit? Science is upending our understanding of phone use and just how damaging the urge to doom-scroll can be. Are smartphones really killing our sleep and distracting us more than ever? And is it really impacting the mental health of children? The answers are not what many people assume.

Not only does it perform impressive feats that we see every day, but water can also transform into a superacid, potentially resulting in diamond rain falling on planets in our solar system. Find out how it could be doing this somewhere in the cosmos right now.
