Nature looks at: Keeping electronics from overheating, Covid-19 changes, and how to include minority populations in genetic analyses.
In this episode:
00:46 Cool computers
Keeping components cool is a major hurdle when it comes to increasing electronic power. This week, we find out about a new way to integrate tiny microfluidic channels directly into circuits, to help keep them cool. Research Article: van Erp et al.
06:57 Coronapod
By comparing coronavirus genomes taken from people around the world, researchers are getting an idea of how SARS-CoV-2 is changing as it spreads. We discuss a particular genetic mutation that rapidly became dominant early in the pandemic, and the effect it may have had on the outbreak. News: The coronavirus is mutating — does it matter?
Minority populations are often underrepresented in genetic study recruitment. However, even when data about them is collected it may go unused. We find out why, and what can be done about it. Comment: Don’t ignore genetic data from minority populations
