St. Jude announces breakthrough in eye cancer treatment

...aid. "It could also increase the chance that their vision can be preserved by eliminating the tumor and preventing its spread from the eye to the rest of the body." The discovery that blocking MDMX releases the apoptosis response in retinoblastoma has important implications for certain forms of adult can...

New fMRI technology making brain tumor surgery safer

...bian, M.D. “We perform various language, motor and vision tasks with the patient in the MRI scanner,?Dr. Leach explained. FMRI scanning takes approximately 75 minutes, about 30 minutes longer than traditional MRI. The DTI scan, which takes five minutes, is performed in the same setting. Dr. Leach proc...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

...of reach for the public. Zhang's technological vision would enable scientists to sequence billions of base pairs of DNA in a single day. This is the size of an average mammalian genome and is approximately 10,000 times more bases per day than can be sequenced using current technologies. By increasing t...

Ultrasound upgrade produces images that work like 3-D movies

...n depth perception is largely the result of stereo vision -- the slightly different perspectives of the same scene that are observed by the left and right eyes, Smith said. The brain processes the information to produce a sense of depth, a phenomenon that can't be achieved when viewing a single, flat image....

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

... as a high priority for the institute. Heller's vision is to develop a variety of possible cures for deafness. For the past year and a half, since coming to Stanford from Harvard, he's been focused on two paths: drug therapy -which could be as simple as an application of ear drops - and stem cell tra...

Is there a pilot in the insect?

When they fly, insects use their vision for piloting, just like human pilots. The electric signals from their facetted eyes travel through specialized neurons to stimulate the wing muscles, which let the insects correct their flight and avoid crashes. Could these same neurons be used in a ...

New study challenges 'critical period' in childhood vision development

...critical periods, many other aspects of functional vision might be learnable even at later ages. In other words, perhaps our brain is not as rigid as we think, and its plasticity remains even after several years of compromised sensory experience. The results of this study provide an argument for even late-...
