Vast cellular gene-expression atlas could transform brain ageing and disease research

China is changing its doctoral training rules so that PhD students in clinical medicine can earn their degrees without writing a traditional research thesis, according to Nature. The shift, with more degree programmes expected to follow, reflects a move to separate clinical training from research training and could reshape how China educates doctors and clinician-scientists. It matters because China trains a large share of the world's medical researchers, and any change to degree requirements can affect research output and the skills of future physicians.

UK minister Shabana Mahmood has set out proposed changes to the rules governing how legal migrants can settle in the country. The changes could affect eligibility and timelines for settlement, with significant implications for migrants and their families.
