Draft sequence of chicken genome completed
...r eggs and tastier chicken it's giving scientists surprising insights into the human genome. Researchers can use these new data as a tool to identify similar sequences in humans regions previously thought to be 'junk' DNA in the human. These sequences must have an important role if they have been conserved ov...UCSD researchers derive lessons about human evolution from chicken genome
...were probably there at some ancestral point." "The surprising discovery was that chickens are much closer to humans than previously thought when it comes to genomic architecture," said Pevzner, a professor in UCSD's Jacobs School of Engineering who is also an academic participant in Cal-(IT)2's Digitally Enable...Timing scavenging to prevent age-related blindness

Perhaps the same signal triggers a cascade that initiates both concerted uptake and digestion. The authors are now trying to identify the protein that binds to the int...U. of Colorado research team discovers life in Rock Glacier
... a slope to allow them to slide. "This is a very surprising finding, something we did not expect," said Williams. "The upshot is that we have shown that rock glaciers are not biological deserts as had been previously thought by scientists. This is one more example that microbes can live in the most extreme ...Vaccinating wildlife can reduce human risk for Lyme disease
...not as great as the investigators had hoped. A surprising result was that mice are not as important in maintaining the Lyme disease bacterium in nature as previous studies showed. "If only mice were responsible for infecting the ticks, we would have seen a much greater reduction," Fish explained. "We now be...UCSB makes important advances in studies of retinal detachment

"The structural remodeling of retinal neurons in animals following detachment has been assumed to alter synaptic...Violent ocean motion no magic potion for reefs

With their first survey nearly completed, it appears all reefs in the path of hurricanes Frances and Jeanne have been largely scoured free of the menacing seaweed, and many have also been buried in sand.

This phenomenon makes sense when viewed in evolutionary terms.

By analyzing sequence data for the small subunit ribosomal RNA gene, which encodes part of the cell's protein synthesis machinery, they demonstrated that chlorophyll d -prod...Unusual reproductive behavior of odd ants surprises scientists

Among the surprising findings of the study were the complex gene structures discovered in C. neoformans that are unlike those found in previously sequenced yeasts and are reminiscent of the genomes of more complex organisms.

It is likely that OBPs in other insects also work this way, although the pheromones are different in different spec...New research shows in the animal world, it pays to be an imposter

...Sexual orientation is a complex trait, so it's not surprising that we found several DNA regions involved in its expression." "Our best guess is that multiple genes, potentially interacting with environmental influences, explain differences in sexual orientation." The genomes of 456 men from 146 families with tw...
