Addressing the problem of sudden food scarcity in US cities, and the up-and-coming field of computational social science.In this episode:00:45 Food shocksClimate change, the COVID-19 pandemic, and geopolitical crises can cause food shortages. To tackle this issue, Alfonso Mejia and colleagues have modelled how to best mitigate these food shocks in US cities. Alfonso tells us about the new analyses and what steps cities could take in the future.Research Article: Gomez et al.News and Views: How to buffer against an urban food shortage06:07 Research HighlightsA tiny lattice can withstand the impacts of projectiles at twice the speed of sound, and the neurons that allow humans to perceive time.Research Highlight: Supersonic strikes leave just a dent in this super-light materialResearch Highlight: The ‘time neurons’ that help the brain keep track08:25 Computational Social ScienceBig data is transforming research, and social science is no exception. This week, Nature is running a special issue on ‘computational social science’. We catch up with some of the editors involved to find out more about this up-and-coming field.Collections: Computational Social Science19:27 Briefing ChatWe discuss some highlights from the Nature Briefing.
