UF scientists reveal ancient origin of vertebrate skeleton

...ll, the lamprey and its cousin, the hagfish, offer insight into the early Cambrian period 540 million years ago, when multicellular animals first began to make shell and other hard body parts. About 40 million years into the process, jawed and jawless vertebrates branched into different paths from the starti...

Vaccine provides 100 percent protection against avian flu virus in animal study

...in the Pacific Ocean. The pioneering study yielded insight into the specialization of microbial communities at each depth--ranging from 40 to more than 13,000 feet. "By reading the information stored in the genomes of entire microbial communities, we can begin to measure the pulse of this marine ecosystem,"...

Wyoming cloud seeding experiment begins this month

...in the Pacific Ocean. The pioneering study yielded insight into the specialization of microbial communities at each depth--ranging from 40 to more than 13,000 feet.

Depression model leaves mice with molecular scar

...e week of February 26, 2005. "Our study provides insight into how chronic stress triggers changes in the brain that are much more long-lived than the effects of existing antidepressants," explained Nestler. Mice exposed to aggression by a different dominant mouse daily for 10 days became socially defeate...

Common molecular 'signature' identified in solid tumors

...mote malignant growth. The finding provides more insight into miRNA as an emerging class of gene regulators and may also pave the way for new approaches in diagnosis and treatment. The study appears online in the Proceedings of the National Academy of Sciences. Scientists have only recently begun to un...

Yale scientists decipher 'wiring pattern' of cell signaling networks

... how they are coordinated to work together. "This insight into the regulation and integration of biological networks has broad applications for basic science and clinical research," said Snyder. "Biological networks determine the development and function of organisms from the single-celled yeast to man; abe...

Have a taste for fat? Yes! A sensor in the mouth promotes preference for fatty foods

The reason why antiviral therapy can't annihilate HIV infection, and what to do about it

...ae-Wook Chun and colleagues from the NIH offer new insight into the eradication of HIV in infected individuals receiving antiviral therapy. The authors focused on HIV-infected patients who had received effective antiviral therapy for extended periods of time and examined the nature of their residual virus ...

Biologists discover new pathway into plant cells

...et specific genes. This is a new and unprecedented insight into how plants can work." The process of proteins getting inside of cells and affecting their behavior is common in animal cells, the scientists said. For instance, that's how the AIDS virus causes its damage. But the same process had never before ...

Twin molecular scissors link creation of microRNAs with gene-silencing

... at The Wistar Institute has provided considerable insight into the world of miRNAs. In their first study, which appeared last year in Nature, they identified a two-protein complex, called the microprocessor, which controls the earliest steps in the creation of miRNAs in the cell nucleus. In their next study...

USC researchers track down the stem cells that create feathers

...ents and/or asymmetric cell behaviors. While this insight into the formation and regeneration of feathers is fascinating, it is the potential for application to human stem-cell studies that really motivates Chuong and his team. "What we are really learning about is how stem cells are assembled into organs ...

Sea slug mixes chemical defense before firing at predators

...n of the Journal of Experimental Biology, provides insight into a natural chemical process with potential industrial applications. In the study, a research team led by Georgia State University biologist Charles Derby, PhD, examined the ink and opaline glands of Aplysia sea slugs for the chemicals L-lysine, ...

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool

...experimental analysis of duplicated genes provides insight into mechanisms of evolution When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to prese...

Key brain regulatory gene shows evolution in humans

...l psychiatrists and psychologists can give us more insight into that aspect." Wray and his colleagues have already identified a collection of some 250 other candidate genes -- mainly those active in the brain -- that they are beginning to analyze for evidence of evolutionary selection. They plan to perform ...

Evolutionary conservation of a mechanism of longevity from worms to mammals

...matode model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. In a recent study, Dr. Hekimi and colleagues of McGill University (Canada) report that inactivation of the gene mclk1, the mur...

Noise And Delays Explain Why Some Genes Oscillate In Activity

...lled positron emission tomography, or PET, to gain insight into CX717's neurobiological role. The PET signal reflected the distribution and rate of metabolism of ingested radioactively labeled glucose in the monkeys' brain cells. By measuring regional brain glucose metabolism, the researchers determined that...
