Ecology :: Soil nutrition affects carbon sequestration in forests

On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric concentrations of carbon dioxide (CO2), the major greenhouse gas driving climate change.

Memory :: Why we ‘never forget a face’

Are you one of those people who never forgets a face? New research from Vanderbilt University suggests that we can remember more faces than other objects and that faces “stick” the best in our short-term memory. The reason may be that our expertise in remembering faces allows us to package them better for memory.

Psychology :: Effects of national trauma on Americans’ health

Do galaxies follow Darwinian evolution?

Using VIMOS on ESO’s Very Large Telescope, a team of French and Italian astronomers have shown the strong influence the environment exerts on the way galaxies form and evolve. The scientists have for the first time charted remote parts of the Universe, showing that the distribution of galaxies has considerably evolved with time, depending on the galaxies’ immediate surroundings. This surprising discovery poses new challenges for theories of the formation and evolution of galaxies.
