USDA Forest Service (FS) research suggests that a decline in the abundance of freshwater mussels about 1000 years ago may have been caused by the large-scale cultivation of maize by Native Americans. view more (2005-06-08)
Healthy older brains not significantly smaller than younger brains, new imaging study shows
The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the... view more... (2009-09-08)

Solar Contribution To 'Global Warming' Predicted To Decrease
New research on the sun's contribution to global warming is reported in this month's Astronomy & Geophysics. By looking at solar activity over the last 11,000 years, British Antarctic Survey (BAS) astrophysicist, Mark Clilverd, predicts that the sun's contribution to warming the Earth will reduce slightly over the next 100 years. This is a... view more... (2003-10-01)
