Size and positioning of floral anthers facilitates pollen collection by bees

...e moths and butterflies that are often brilliantly colored to warn potential predators that they carry toxins, flowers and the fruits they produce have brilliant colors and unusual shapes because they want to attract the attention of pollinators and frugivores who will disperse their pollen and seed, thus gu...

Some forest birds can survive in agricultural countryside with limited habitat conservation

...ular species. Then, they tagged each bird with two colored leg bands and an aluminum ring with an identification number. Using false-eyelash glue, they attached a radio-transmitter with a battery life of one-to-three months. The team tagged and tracked a total of 156 birds during the study. "We had a Pathf...

Newborn neurons like to hang with the 'in' crowd

...environmentlarge cages filled with running wheels, colored tunnels and playmatesboost the number of neurons that manage to hook up with the existing network to 80 percent, reinforcing the observation that using one's brain cells is the best way to optimize brain function throughout one's lifetime. ...

The stem cells that weren't there

...hner. By providing rats with a timed sequence of colored dyes in their drinking water, the researchers were able to see discrete beta cells in the rat pancreas, shining in single colors that indicated a sequence of cell divisions. In contrast, the rapidly dividing cells in the rats' intestine showed blende...

Sandia researchers take new approach to studying how cells respond to pathogens

...are tagged with fluorescent molecules, essentially colored dyes. The dyes range from green to red and give researchers the opportunity to track proteins and see, for example, the dynamic cellular production of proteins or protein-binding processes inside or on the surface of the cells. The team is developi...

Light-activated therapy targets DNA components

...ing of the DNA targeting unit allows us to produce colored DNA-Complex assemblies that are easily photoactivated with visible light." Avijita Jain of Bhopal, India, a Ph.D. candidate in chemistry at Virginia Tech, has designed a selective complex shown to inhibit growth in E. coli bacteria. The groups pr...

Genetic studies endow mice with new color vision

...e whether the female mice could discriminate among colored lights by comparing the relative activation of the M and L cone cells. The researchers conducted tens of thousands of tests in which two different wavelengths or intensities of light were displayed on three test panels. Mice received a drop of soymil...

FISH-ing for links between cancer and aging

... every pair of the 46 chromosomes with a different colored fluorescent dye, enabling investigators to easily see breakage or fusion of chromosomes that are characteristic of damaged DNA under the microscope. Then they artificially supplied the cultured cells with one of two genes-either a functional copy o...

Huddling and a drop in metabolism allow penguins to survive the South Pole cold

...antation, both mates were individually marked with colored strips and released together. Male and female penguins implanted with the loggers were observed daily in the colony using binoculars, at a distance of at least 10 to 20 meters. Breeding success of the entire colony during 2001 was low at 42 percen...

Fruit flies and global warming -- some like it hot

... Loeschcke and Hoffmann did field releases with colored flies exposed to different heat hardening treatments to get estimates of a fitness component in the wild. They used the likelihood to be caught at baits in field sites without natural resources as an estimate of fitness in Drosophila. The results sho...

Eculizumab is well-tolerated and shows significant improvement in PNH patients (Ph III)

... recurrent pain, and intermittent episodes of dark colored urine, known as hemoglobinuria. Importantly, PNH patients are at increased risk of forming life-threatening blood clots, or thromboses, which are a significant cause of death. Eculizumab, a long-acting C5 complement inhibitor, is a humanized monoclon...

Ohio University researchers discover evolutionary oddity in flamingos

...s jaw muscle structure, the researchers injected a colored barium/latex mixture into the blood vessels of a bird that had died and was donated by the Brevard Zoo in Florida. A 3-D view of the bird's head was created using a new computed tomography (CT) scanning technique developed by the Ohio University team...

Researchers make nanosheets that mimic protein formation

...ally nanoparticles." The sheets, which can appear colored under UV illumination from bright green to dark red depending on the nanoparticle size, are made from cadmium telluride crystals, a material used in solar cells. The sheets are about 2 microns in width, about 1/5 the thickness of a human hair. Scien...

Mechanism to organize nervous system conserved in evolution

... two years ago, Mizutani was able to use different colored fluorescent molecules to determine which neural identity genes were activated in response to the BMP gradient. She determined that BMPs acted the same way as they do earlier during neural induction, namely to shut off neural identity genes. Because B...

Discovery of genetic mutation in Florida beach mice suggests extinct mammoth had light and dark fur

...ese Atlantic coast beach mice have similarly light colored coats. The results suggest that beach mice gain their light coloration through different genetic mechanisms. "There is apparently more than one way genetically to become a light-colored beach mouse," says Hoekstra. Other genes also contribute t...

Zebra finch males prefer females with exaggerated maternal traits

...ferred females with beaks that were more extremely colored than their mothers' beaks. This "peak shift" effect is known from other learning processes in which animals learn to distinguish different stimuli, but the presence of this effect in the imprinting process has not been demonstrated previously. The ou...
