Science Nation - Follow the Water

submitted by: nsf
Already parts of the world suffer from lack of water, and with increasing demand it's expected to get worse. To better understand and predict drought, 30 universities are collaborating in a multi-disciplinary effort called the Shale Hills Project. Among the studies, is field research following the life cycle of water along the Susquehanna River Basin, the main tributary to the Chesapeake Bay. With support from the National Science Foundation, civil engineer Chris Duffy and his team at Penn...

Science Nation - Antarctica Rocks

submitted by: nsf
Geologist John Goodge looks for clues about Antarctica's past in the two percent of the continent that is not covered in ice! The University of Minnesota, Duluth professor studies rocks that help provide evidence about how this desolate continent has formed and changed over time. He also hopes to get a better idea of what the Earth looked like long before the seven continents we have now. Goodge and his colleagues are supported by the U.S. Antarctic Program, which is managed by the National...

A new way forward for fibroblasts

submitted by: JCB
Fibroblasts moving across two-dimensional surfaces form lamellipodial protrusions at their leading edge, but how cells move through three-dimensional environments is less well understood. Petrie et al. reveal that, depending on the strength of intracellular RhoA signaling and on the elastic properties of the extracellular matrix, fibroblasts can migrate through 3D environments using either lamellipodia or blunt, cylindrical protrusions called lobopodia. This biosights episode presents the...

T Cells Rho across the endothelium

submitted by: JCB
During an immune response, T cells move into tissues from the vasculature by crossing the endothelial cell layer lining blood vessel walls. Heasman et al. reveal that this transendothelial migration requires signaling at both the front and back of leukocytes by the small GTPase RhoA. This biosights episode presents the paper by Heasman et al. from the August 23, 2010 issue of The Journal of Cell Biology, and includes an interview with senior author Anne Ridley. Produced by Caitlin Sedwick...

GEOLOGY ROCKS!!! :D Mary Kazee, Jeremy Kazee and Jessica Herman originated the idea and filmed it. Becky Parkin, Interpretive Naturalist for Lake Metroparks, guided our hike and Michael Girbino helped edit our video. The rock scenes were filmed in Chapin Forest, in Kirtland, Ohio, and the dark segment is ACTUALLY the bonds breaking in the quartz!! How cool, right?
