Mark Heinlein, also from the Gardens, transforms a three-year-old juniper into an ancient, windswept tree in 25 minutes. Originally aired as an episode of "The Good Green Earth."
Over the past four decades, evolutionary biologists Rosemary and Peter Grant have documented the evolution of the famous Galápagos finches. They track changes in body traits directly tied to survival, such as beak length, and identify behavioral characteristics that prevent different species from breeding with one another. Their pioneering studies have revealed clues as to how 13 distinct finch species arose from a single ancestral population that migrated from the mainland 2 million to 3 million years ago.
With funding from the National Science Foundation, Peter Ungar is revealing more details about the lives of human ancestors, and he’s doing it through dentistry. The University of Arkansas anthropologist uses high tech dental scans to find out more about the diets of hominids, a technique that sometimes leads to new and very different conclusions. While anthropologists traditionally determine the diets of our ancestors by examining the size and shape of teeth and jaws, Ungar's powerful microscopes paint a more detailed picture by looking at wear patterns on teeth.
University of Pennsylvania ecologist Peter Petraitis, California State Northridge biologist Steve Dudgeon, and their team have been returning to Maine’s rocky intertidal zone every spring and summer for nearly two decades. With support from the National Science Foundation (NSF), they survey a network of 60 experimental plots. The big question that brings them back year after year: Is an ecosystem like this a stable and permanent fixture, or, under harsh conditions, could it reach a tipping point? The idea is that changes in conditions could cause a switch from one community to another, such as from mussel beds to rockweed, and then back again. Part of the National Science Foundation Series “Science Nation.”
Many viewers enjoy three-dimensional technology, but a few feel the need to look away. A number of neurological and visual conditions can cause someone to experience nausea. It's a type of motion sickness without the motion. Fred Bonato of St. Peter's College in Jersey City has spent years steadily tracking what he calls "cyber sickness.”
