NSF Science Now: Episode 23

The video covers several scientific topics, starting with the development of a microfluidic device by NSF-funded researchers at the University of Washington to improve early diagnosis of pancreatic cancer. It then shifts to a study on cougars' dietary adaptations that may have helped them survive a mass extinction event 12,000 years ago. The discovery of the earliest pterodactyloid in China is also discussed, highlighting its evolutionary significance. Finally, the video provides an overview of the USA Science and Engineering Festival, showcasing various NSF-funded exhibits.
