Devising Nano Vision for an Optical Microscope

...all realm of molecules and atoms may not be out of sight for the venerable optical microscope, after all. In fact, research at the National Institute of Standards and Technology (NIST) suggests that a hybrid version of the optical microscope might be able to image and measure features smaller than 10 nanom...

Insight into our sight: A new view on the evolution of the eye lens

...on and Radboud University in The Netherlands. Our sight relies on the ability of our eye to form a clear, focused image on the retina. The critical component in focusing is the eye lens, and the physical properties that underlie the transparency of the lens, as well as its ability to precisely refract lig...

Grasshopper love songs give insight into sensory tuning

...d by a baby's howl or who have been riveted by the sight of an attractive person knows, nature has evolved sensory systems to be exquisitely tuned to relevant input. A major question in neurobiology is how neurons tune the strength of their interconnections to optimally respond to such inputs. Neuronal ci...

On a wing and a prayer - Alaska researchers seek clues to bird flu

...chcock's "The Birds" made many of us uneasy at the sight of amassing gulls years ago, today public health officials around the world are beginning to cast an equally uneasy eye toward migratory birds, especially in Alaska, following recent outbreaks of avian influenza in Southeast Asia and, last week, in S...

Gene therapy works in mice to prevent blindness that strikes boys

...mic molecular genetics. "These children lose their sight gradually, often with devastating results. What happens is the retina actually begins to split in the middle, causing loss of central vision - that's the vision that you need to be able to read or walk around." Scientists say the gene transfer metho...
