Tandem transcripts team together

...epen our understanding of the eukaryotic genome, a picture emerges that challenges this paradigm ?not a picture in which the sequences in the genome have distinct functions, but rather one in which the sequences ...

UF scientists trace origin of shark's electric sense

...cean, Cohn said. "If you think of this in the big picture of evolution of sensory systems, such as olfaction, hearing, vision and touch, this shows sharks took a pre-existing genetic program and used it to build yet another type of sensory system," Cohn said. UF and University of Louisiana researchers anal...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

... climate change. And, by providing a more complete picture of the marine web of life, it is another step toward managing the Gulf of Maine as an ecosystem ?one of the primary goals of fisheries laws in the U.S. and Canada and of recent ocean commissions. "Though the Gulf of Maine is one of the most intensiv...

Biologists visualize protein interaction that may initiate viral infection

...ed cryo-electron microscopy, the biologists took a picture of the virus attached to the CRD shortly after the two joined together. It is the first time scientists have visualized the virus and CRD binding. "We formed the virus-CRD complex, took a snapshot and determined its structure," said Michael Rossmann...

Polymer aids in blood clotting, pointing way to new treatment

...ther diseases with coagulation deficits. "The big picture is that we've found a new function for an ancient molecule," he said. "Polyphosphate has been around for billions of years. Roberto's discovery that the granules in platelets are like the granules in trypanosomatids was a key breakthrough." Docampo'...

Rice University researchers create 'nanorice'

...mation of amyloid-beta peroxidase provides a clear picture of why cells die in the brain of Alzheimer's patients. Our next challenge is to develop drugs that directly and selectively target the excessive peroxidase of amyloid-beta, which could lead to the first significant therapy for Alzheimer's disease." ...

Advanced genomics and proteomics improve the diagnosis and treatment of a deadly lung disease

...llography to assemble a detailed three-dimensional picture of an enzyme known as Dicer. In cells, Dicer jumpstarts RNA interference, a process that causes genes to be turned off and which, in turn, prompts a host of key developmental events.

Multi-million pound UK Biobank underway

...imitations, which mean we still don't have a clear picture of how these different elements interact. By being so large and detailed, UK Biobank will be able to study many different risk factors together, each of which may have only modest effects on the likelihood of getting some particular disease." Taking...

Minor mutations in avian flu virus increase chances of human infection

...erg said. "The glycan microarray offers a detailed picture of viral receptor specificity that can be used to map the evolution of new human pathogenic strains, such as the H5N1 avian influenza, and could prove invaluable in the early identification of emerging viruses that could cause new epidemics." Other ...

Watching the brain switch off 'self'

...xperience to the outside world. "To conclude, the picture that emerges from the present results is that, during intense perceptual engagement, all neuronal resources are focused on sensory cortex, and the distracting self-related cortex is inactive. Thus, the term "losing yourself" receives here a clear neu...

On a fly's wing, scientists tally evolution's winners and losses

...]). The study of this chromosome gives a clearer picture of how genome changes through evolution, Lupski said. For example, breaks in synteny or the maintenance of the order of genes between species coincide with changes in the architecture of the chromosome itself. In some cases, DNA repeats get in the wa...

Researchers solve mystery of how nuclear pores duplicate before cell division

...the nuclear membrane. This discovery adds to the picture of how a cell divides in such a way that the genome (genetic blueprint) encased inside the nucleus can continue communicating with the rest of the cell. "This issue is as important to understanding the cell cycle as is the question of how DNA replica...
