Deep in the interior of Antarctica, scientists work to unlock the secrets of our planet's past. (Please note that this is the first in a three-part series, which includes "Life on the Ice" and "Modeling our Future Climate")

Science Nation - How Does Your Garden Grow?

submitted by: nsf
At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of...

Science Nation - Marshes and Sea Level Rise

submitted by: nsf
With support from the National Science Foundation, Villanova University marine scientist Nathaniel Weston studies how both land use and climate change can impact habitat in tidal marshes, including how rising sea levels may affect microbes and other plants and animals. Rising sea levels can actually cause marshes to grow in very different ways. His experiments are already simulating different amounts of sea level rise in several tidal creeks in the Delaware River estuary. He studies how...

Science Nation - Lord of the Tree Rings

submitted by: nsf
David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts. In fact, in 1998, he made the front page of the New York Times with his discovery that drought...

New Study Links Dust to Increased Glacier Melting, Ocean Productivity

submitted by: UMiami_RSMAS
University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems. UM Rosenstiel School Professor Joseph M. Prospero and colleagues Joanna E. Bullard and Richard Hodgkins...

GREEN REVOLUTION: CITYCAR

submitted by: nsf
Lisa Van Pay of the National Science Foundation meets with Will Lark, an MIT graduate student working on the CityCar project. The two discuss the technologies that make this vehicle unique and explore the relationship between art, science, and design. The CityCar team hopes that their ideas will some day be part of the solution to problems common to many cities: pollution, traffic and lack of green space. This story allows the viewer to see how researchers identify problems, build models to...
