Tufts researchers shine light on firefly mysteries

...ton, Tufts University biologists are continuing to shine new light on the frenzied love life of fireflies. For the first time, researchers will explore the question of whether male fireflies' flashing light ?previously shown in one species to indicate superior physical and genetic quality ?has evolved in ...

Color perception is not in the eye of the beholder: It's in the brain

...pe. Imaging the living retina allowed Williams to shine light directly into the eye to see what wavelengths each cone reflects and absorbs, and thus to which color each is responsive. In addition, the technique allows scientists to image more than a thousand cones at once, giving an unprecedented look at ...

Purdue's gold nanorods brighten future for medical imaging

...s with a certain "aspect ratio" of length to width shine brightly when illuminated by light in this spectral region. The gold nanorods are ideal for a type of imaging called "two-photon fluorescence," which provides higher contrast and brighter images than conventional fluorescent imaging methods. Photons...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

... pass harmlessly through our cells," Dai says. But shine a beam of near-infrared light on a carbon nanotube...can take the beam and put anywhere we want. We can shine it on a local area of the skin or inside an internal organ using a fiber-optic device." Dai has app...

Customized gene chip provides rapid detection of genetic changes in children's cancer

... on the microarray, they cause fluorescent tags to shine under laser light. This is a signal that a particular gene variation is present in the sample. "We can test DNA from peripheral blood and from the tumor, and we should see a loss of signal in the cancer," said Dr. Fortina. He noted that the research...

Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

...e slide is rinsed. An optical device will then shine a strong light on the slide. If, due to the protein/antibody bond, the retroreflectors remain on the slide, they will clearly reflect the light, indicating the presence of Norwalk. If no light is reflected, then no protein/antibody bond has occurre...

Researchers offer clues to how leaves patterns are formed

...ormone auxin with a fluorescent tag, he could then shine a light on the leaves and watch how auxin was being transported during vein formation. Thanks to this approach, the team identified cells within individual veins that transport the hormone auxin in two opposite directions. He also showed for the firs...

Snakes' virtual glasses, leopard spots and all-optical transistors

... and coated in a layer of polymer. The researchers shine two beams of light on the structure: a signal beam and a control beam. When the beams strike the patterned film they produce plasmons, which are essentially blobs of electron gas near the surface of a metal. Varying the intensity and the color of the...

With fruit fly sex, researchers find mind-body connection

...es have thousands of genes in common, the work can shine a light on the biological roots of human behavior. For example, McKeown recently helped discover a genetic mutation that causes flies to develop symptoms similar to Alzheimer's disease ?a gene very similar to one found in humans. Some of McKeown's...

Gene key to taste bud development identified

...reen when exposed to ultraviolet light. "When we shine light on tissue from these animals, any cell that is expressing SOX2 will fluoresce, or light up," Pevny explained. "This allows us to directly visualize those areas where SOX2 is active. It is a very powerful tool." In their work, Hogan and her co...
