NSF Science Now: Episode 39

The video covers three main topics: a new device that helps blind people monitor their guide dogs' health by tracking heart and respiratory rates; the discovery of a new ceratopsian dinosaur species in the Gobi Desert, which provides insights into dinosaur evolution; and an unprecedented sighting of orcas near Palmer Station in Antarctica, showcasing their hunting behavior.

What is the primary purpose of the new device developed for guide dogs?

• It had three horns

• It walked on four legs

Where was the new dinosaur species discovered?

• In the Gobi Desert

• In the Amazon rainforest

• In the Rocky Mountains

• In the Sahara Desert

• They were hunting in a coordinated manner

• They were playing with dolphins

• They were migrating to warmer waters

What was the outcome of the orcas' hunting attempt?

• They caught a different prey
