Bones in motion: Brown scientists to create new 3-D X-ray system

... leap of frogs. "This will be like having X-ray vision ?you'll be able to see through skin and muscle and watch a skeleton move in 3-D," said Elizabeth Brainerd, the Brown University biology professor overseeing development of the new system. "Imagine animated X-ray movies of flying bats or flexing knees...

New technique will produce a better chromosome map

... research assistant Mert Dikmen, who uses computer vision technologies under the supervision of Beckman Institute professor Thomas Huang to analyze the images. "Our system will give an impartial estimate of the band location. It will not be researcher-dependent. It will be objective." To improve chromoso...

New research shows sharks use their noses and bodies to locate smells

...ion of the olfactory system, the lateral line, and vision in odor source detection and localization in the smooth dogfish shark. The results, which appear in the June 1 issue of the Journal of Experimental Biology, show that this shark is severely handicapped in its ability to locate the source of an odor w...

UCF nanoparticle offers promise for treating glaucoma

...eated, can result in damage to the optic nerve and vision loss. High pressure occurs, in part, because of a buildup of carbon dioxide inside the eye, and the compound blocks the enzyme that produces carbon dioxide. Seal and a team of collaborators including Sanku Mallik, of North Dakota State University...

Dual-imaging technique useful before -- and during -- brain surgery

...For example, explains Leach, patients with limited vision may not demonstrate as much activity in the brain in areas linked to vision during functional MRI testing. “That doesn’t necessarily mean that there’s no function there—it ...

New study finds genetically engineered crops could play a role in sustainable agriculture

...tages of GM crops depend on the specific goals and vision for agroecosystems. As NCEAS Director, Jim Reichman explains, “This important study by an interdisciplinary research team reveals how an in-depth analysis of large quantities of existing data from many individual experiments can provide a greate...
