A beggars banquet -- life in a shared nest

Researchers found that crow chicks raised alongside a cuckoo chick begged less intensely than those in nests without any unrelated broods present. Despite this, the young crows ultimately grew bigger than the cuckoos. The study suggests that sharing the nest with a cuckoo may be advantageous for crow chicks.

Scientists uncover how molecule protects brain cells in Parkinson's disease model

Researchers found that serum glucocorticoid kinase 1 (SGK1) protects brain cells by blocking pathways involved in neurodegeneration and alleviating mitochondrial dysfunction. Increasing SGK1 levels offers a potential therapeutic approach for Parkinson's disease, as naturally occurring levels are not sufficient to promote cell survival.
