A Role for Focal Adhesions and Extracellular Matrix in Traumatic Axonal Injury
(2014-10-21)
Traumatic Brain Injury (TBI) is linked to a diverse range of diffuse pathological damage for which there is a severe lack of therapeutic options. A major limitation to drug development is the inability to identify causal ...
Microbial colonization and dissolution of mercury sulfide minerals
(2014-10-22)
Mercury (Hg) is a toxic heavy metal that poses significant human and environmental health risks. Mineral-associated Hg is the largest reservoir of Hg in the environment where it can account for nearly 60% of the global Hg ...
Optomechanics and nonlinear mechanics of suspended photonic crystal membranes
(2014-10-21)
The recent demonstration of strong interactions between optical force and mechanical motion of an optomechanical structure has led to the triumphant result of mechanical ground-state cooling, where the quantum nature of a ...
Collective Construction by Termite-Inspired Robots
(2014-10-21)
Construction usually involves careful preplanning and direct human operation of tools and material. Bringing automation to construction has the potential to improve its speed and efficiency, and to enable building in ...
Near-surface Nitrogen Vacancy Centers in Diamond
(2014-10-21)
The nitrogen-vacancy (NV) center is a point defect in diamond and has been championed as a promising solid-state "artificial atom." NV center properties such as its bright luminescence, room-temperature optical readout of ...
Vertical Silicon Nanowires for Image Sensor Applications
(2014-10-21)
Conventional image sensors achieve color imaging using absorptive organic dye filters. These face considerable challenges however in the trend toward ever higher pixel densities and advanced imaging methods such as ...
Flight Control of a Millimeter-Scale Flapping-Wing Robot
(2014-10-21)
Flying insects display remarkable maneuverability. Unlike typical airplanes, these insects are able to execute an evasive action, rapidly change their flight speed and direction, or leisurely land on flowers buffeted by ...
