Mapping Fly Brains

Scientists have achieved a groundbreaking feat by mapping the intricate brain of a fly, revealing its 130,000 cells and 50 million connections. This research could provide insights into neural processes that may scale up to understanding human cognition. Meanwhile, a new initiative in the UK aims to sequence the genomes of newborns to screen for over 200 rare genetic disorders, raising important ethical questions about the implications of genetic information.
