Everyone knows that goats are the new cats, which is to say, they're the most popular creatures to be found on the Internet. They can also be found, it would seem, in the Berkeley Hills thanks to the Lawrence Berkeley National Laboratory, known as the Berkeley Lab. From the lab's website,

Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence’s belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.

As the lab describes its goat program, "The brush-eating goats are back at the Lab for their annual summer visit, eating dry grasses from the hillsides to reduce fire risk."

Also, quick note on the video. It's taken by David Stein, and he's listening to NPR because it's Berkeley.
