In this episode:00:45 Implanted brain organoids could offer new insights into diseaseBrain organoids — lab-grown, self-organizing structures made of stem cells — are used in research to better understand brain development and disease progression. However, these structures lack connections seen in real brains, limiting their usefulness. To overcome this, a team has now transplanted human organoids into the brains of newborn rats, showing that these implanted organoids respond to stimuli and could influence the animals’ behaviour.Research article: Revah et al.News and Views: Human brain organoids influence rat behaviour09:20 Research HighlightsThe subtle timing shift that gives jazz music its ‘swing’, and why hydrogen power could be a cost-effective way to reduce heavy industry emissions in China.
