#110: Solution for Ukraine food crisis; why young blood rejuvenates; climate horror in Australia; Hannah Peel’s new music

In vampire news, the team explains how we may have found the secret ingredient in young blood that causes it to have rejuvenating powers. This comes off the back of a 2012 study which saw old mice rejuvenated fur after being transfused with the blood of the young.

And finally composer Hannah Peel, whose work is influenced by science and nature, helps us escape from the mayhem, sharing clips from her new album ‘The Unfolding’.
