The video covers three NSF-funded research projects. The first explores how different shark species use their teeth for feeding, revealing a trade-off between sharpness and longevity. The second project uses crowdsourcing to improve the quality of test questions, offering a faster and cheaper alternative to traditional methods. The final project introduces a computer program that enhances the accuracy of detecting recurring brain cancer in MRI scans, outperforming human neuroradiologists.
