Timing is everything: First step in protein building revealed

...ces. "We see disease largely as anincorrect timing event -- the wrong thing happening at the wrong time,or the lack of the right thing."As a result, Lorsch studies the timing of how the ribosome complexitself assembles and how other factors come and go as it translatesgenetic information to build proteins,...

Researchers reveal the infectious impact of salmon farms on wild salmon

...xported its lice generating properties ?a cyclical event establishing the potential for re-infections up and down the coast. As the abundance of lice increases, we are now realizing that lice will attack other species, not only salmon, but other fish such as herring which are the spark plugs of the entire ...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

...zer 1.0" (pdf) describes MSI's discrete stochastic event simulator, which keeps trackof the thousands of complex species formed from pathway proteins as itsimulates reactions between them by a standard Monte Carlo method. Adistinguishing aspect of Moleculizer is its ability to generate proteincomplexes and...

New research indicates a 'troubled' greenhouse is brewing

...o have been in play during a well-known greenhouse event some 55 million years ago during the late Paleocene epoch. Retallack explored the relationship between seasonality and rainfall in soils, then applied the same techniques to buried soils spanning the ancient greenhouse event. "This is known to have ...

Measuring the impact of post-genomics on Mediterranean populations

... bordering the Mediterranean Sea. Delegates at the event also discussed the importance of Euro-Mediterranean partnerships in order to capitalise on post-genomic research. The life sciences ?in particular following the mapping of the human genome ?offer vast opportunities to improve scientific knowledge an...

Scientists find fossil proof of Egypt's ancient climate

... Our climate data from this 130,000-year-old humid event suggest that this would have been a particularly good time for a northward migration through Africa following reliable water resources, since it seems to be the strongest humid phase in this region over the past 400,000 years. We're also testing the ...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...ission to Candida albicans yeast. The transmission event led to a new strain of Candida prion fibrils that could in turn infect Saccharomyces. Although fibril shape appears to be the deciding infective factor, amino acid sequence is still important because it defines a set of possible preferred fibril sha...

Products containing specific probes for detecting alternative splice forms protected

... CEO, ExonHit Therapeutics. "This is a significant event for ExonHit as we have been quite successful in leveraging strategic assets in multiple arenas, including the therapeutic, diagnostic and research tool markets ?areas in which these claims will further increase our market share." ...

First technology to remove prions that cause vCJD from blood launched

...ability of our prion reduction filter is a seminal event heralding a new era in blood safety," says Eric Krasnoff, Chairman and CEO of Pall Corporation. "We are working very closely with health authorities, starting with the nations hardest hit by vCJD, to help protect the safety of the blood supply and pr...

Advancements In Genomics Foster Deep Sea Discoveries

... pressure, and that triggers a signal transduction event that activates the expression of genes that help the cells to adapt to the increased pressure,?said Bartlett. The scientists found other tantalizing discoveries in Photobacterium profundum, including a novel fermentative process, adaptations to elect...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

Disease progression model of pancreatic cancer developed by Penn researchers

...eatic and other epithelial cancers because the key event of genomic instability that has been very difficult to model in the mouse appears to be recapitulated here." In the pancreatic tumors and metastases from the mouse model, the investigators characterized other molecules implicated in pancreatic cance...

Low oxygen likely made Great Dying worse, greatly delayed recovery

...ceded by elevated extinction rates before the main event and was followed by a delayed recovery that lasted for millions of years. New research by two University of Washington scientists suggests that a sharp decline in atmospheric oxygen levels was likely a major reason for both the elevated extinction ra...

Scientists reveal the shape of a protein that helps retroviruses break into cells

Retrovirus struck ancestors of chimpanzees and gorillas millions of years ago, but did not affect ancestral humans

...inate in a common ancestor of humans and apes. The event also took place between three and four million years ago, well after the separation of humans from apes. That split is estimated to have occurred five to seven million years ago. During that period, ancestral humans were likely to be living in the sa...

Specifically, Gleevec might be useful as a preventative against adverse effects of smallpox vaccine, enabling clinicians to use the vaccine even in people who otherwise could not take it. Given for a short per...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

...a bad copy (mutation) of a gene, the recombination event could cause an offspring to inherit two bad copies of the gene, which would result in a mutant cell. This process simultaneously activates the green fluorescent protein, which turns the mutant cell green. "If there is no recombination, there are nei...

Enlisting genomics to understand flu evolution

...y is the first to examine in detail a reassortment event from a persistently cocirculating minor strain to a previously dominant strain leading to an epidemiologically significant outcome--the emergence of the "Fujian" strain in the 2003-2004 flu season. The Institute for Genomic Research, with funding fr...
