Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Measles Virus Against Cancer

...cells. The measles virus became the focus of this vision several years ago when the surprising finding was made that the measles strain used internationally for vaccinations has natural anticancer activity. "But we had a concern that the measles virus may be a little too promiscuous in its ability to infe...

Researchers discover molecular mechanism that desensitizes us to cold

...other receptors, including ones involved in taste, vision and fertilization. Therefore, the findings may have important implications across a wide range of areas.

Migratory songbirds have a specialized night-vision brain area

...ed. The researchers found that blocking night-time vision dramatically reduced gene activity in cluster N. "This result confirmed that night-migratory birds seem to have a brain area specifically adapted for seeing during their night-time flight," Jarvis said. The researchers suspect that the newly discove...

Brain May Be Less Plastic Than Hoped

...n the fovea—a small depression in the retina where vision is most acute—and covering the blind spot. They made baseline measurements of the cortical quiet zone two to three hours after the laser surgery and compared them to new readings taken every few weeks for up to seven and a half months. “If the visua...

Bobbing birds do it for a reason

...iding "motion blur" was essential for high-quality vision in birds; many animals, including humans, stabilize visual fields only transiently, through the use of eye movements alone, and accept quite a lot of so-called "visual flow" when in motion. In new work addressing this question, Thomas Cronin and Mat...

Penn Researchers Use Robotic Surgery

...s to see the surgical site more closely than human vision allows, and to work at a smaller scale of detail than conventional surgery permits. Unlike other endoscopic systems now in use, which afford reverse-image views that require counter-intuitive movements by surgeons (whereby the surgeon must move his h...

Novel live reporting system to track cells

...y modified cells. This method grew out of a joint vision that originated 10 years ago in collaboration with the late Dr. Yoav Citri. Ferritin's advantage is that it is visible in MRI without the need for an additional contrast material. This technique has far-reaching implications for monitoring the progre...

Second Sight's intraocular retinal prosthesis is taking the first step to replacing those cells with its device, a 4-by-4 grid of platinum electrodes embed...
