New tech helps handlers better monitor health of guide dogs- NSF Science Now 39

The video covers three main topics: an innovative guide dog harness developed by Shawn Milan and his team to help blind handlers monitor their dogs' health; the discovery of a new dinosaur species, Ceratops Wu Saiwan ensis, by NSF-funded researchers in China, which provides insights into dinosaur diversification; and an unprecedented sighting of orcas near Palmer Station, Antarctica, captured on video by Chuck Kimball, showcasing orca behavior and hunting techniques.

What does the discovery of the two early ceratopsian species suggest about their diversity?

Explain the behavior of orcas as observed in the video taken near Palmer Station.
