Mice lacking a gene for making telomeres displayed symptoms of aging, including graying hair and increased tumor incidence. However, the study reveals that telomere loss is not solely responsible for aging, suggesting other mechanisms at play.
Orrin Pilkey, a Duke University geologist, argues that engineering models used to predict natural processes, such as beach erosion, are flawed and damaging to society. He proposes that beach erosion is linked to rising sea levels and that some coastal engineering measures can exacerbate erosion.
Researchers found that angiogenesis, the formation of new blood vessels, contributes to arthritic disease progression. Treatment with an integrin antagonist reduced joint swelling, pannus formation, and cartilage erosion in animal models.
Research at Cambridge and Oxford universities is using magnetic forces to levitate, stir and dam molten metal, reducing pollution and increasing efficiency. New devices are producing high-quality sheet metal with reduced edges and improved aluminum smelting costs.
A Colorado State University project, funded by a $1.8 million grant, aims to catalogue and analyze below-ground organisms and their interactions with surface ecosystems. The study seeks to understand how human activities above ground influence biodiversity below ground and its consequences.

A NASA experiment has yielded new insights into the internal fabric of soil and powders under very low confining pressures. The Mechanics of Granular Materials (MGM) experiment showed unusual density patterns and unique shear band formations, which could lead to improved engineering standards and disaster preparedness.
Recent USGS research reveals little difference in ground motions on Mississippi River bluffs vs nearby floodplain. This suggests areas underlain by rock may experience less shaking than those with alluvium, such as valleys.
