Scientists discover the earliest and most primitive pterodactyloid! NSF Science Now 23.

The video covers several scientific topics. It begins with a discussion on a new microfluidic device developed by the University of Washington to diagnose pancreatic cancer earlier. The next section explores how cougars' diverse diet helped them survive the Pleistocene extinction, unlike other large cats. The video then shifts to the discovery of the earliest pterodactyloid fossil in China, providing insights into pterosaur evolution. Finally, it highlights the USA Science and Engineering Festival, showcasing various NSF-funded exhibits.

What is the primary advantage of the microfluidic device developed by the University of Washington for pancreatic cancer diagnosis?

• It can diagnose multiple types of cancer.

• It allows for direct biopsy tissue analysis without cutting.

• It is reusable and cost-effective.

• It uses traditional 2D imaging techniques.

How did Cougars' dietary habits contribute to their survival during the Pleistocene?

• They hunted in large packs.

• They only ate plants.

• They had a more diverse diet and consumed entire prey.

• They relied solely on scavenging.
