Columbia University licenses next-generation DNA sequencing technology

...Sciences (PNAS). This research paper describes the details of the Sequencing by Synthesis Chemistry and how the approach overcomes accuracy limitations of other next generation DNA sequencing systems. It was also recently announced that Columbia University in collaboration with the Waltham, Mass. based Inte...

Mayo researchers discover HIV dependence on a human protein

...rapy for HIV or safer methods of gene therapy. The details appear today in the journal Science. "How an incoming virus co-opts the cell's assistance as it proceeds to establish its permanently integrated state is a fascinating question," says Eric Poeschla, M.D., the Mayo Clinic virologist who led the resea...

Fast-freeze snapshot yields new picture of nerve-muscle junction

...reeze physical-fixation technique that reveals new details of their location and function in neuromuscular synapses. The technique was used with tiny, one-millimeter-long nematode worms, a lab animal widely studied by neuroscientists. Investigators report the finding in the Aug. 2 issue of the Journal of Ne...

A new approach to growing heart muscle

...as the cells organize into tissue. The U-M team details its achievement in a new paper published online in the Journal of Biomedical Materials Research Part A. And while BEHM is still years away from use as a human heart treatment, or as a testing ground for new cardiovascular drugs, the U-M researcher...

Selecting life: Scientists find new way to search for origin of life

...nal of other techniques can be used to look at the details of the interactions. "What's particularly rewarding about this research is that it's an interdisciplinary effort from different areas of science--biology, chemistry and geology," reflected Hazen. "It marries them to search for an answer to a ques...

Cocaine high caused by interference in neuronal receiving stations

... glutamate receptors on neurons, but the molecular details of those effects were unknown. In their experiments, Wang and colleagues first determined that cocaine reduces the activation of glutamate-responsive neurons by affecting a specific component, or subunit, of the receptor, called NR2B. Further exper...

Global malaria map key weapon in fight against malaria, scientists say

...In their PLoS Medicine paper, Hay and Snow discuss details and goals of the project, which is funded by the Wellcome Trust, the UK's largest biomedical research charity. The map will be constructed using information from sources such as satellites and population censuses. Statistical approaches will enabl...

Protein structure initiative launches new resources for the scientific community

...on. The Knowledgebase also will offer experimental details about each stage of the protein structure determination process, regardless of whether the structure was successfully determined. Information about current PSI proteins being solved will be listed. In addition to searching these details, scientists w...

Scientists crack rhino horn riddle

...arply pointed tip. Scientists have discovered new details about the structural materials that form the horn and the role those materials play in the development of the horn's characteristic shape. The horns of most animals have a bony core covered by a thin sheath of keratin, the same substance as hair...

Cholera pathogen reveals how bacteria generate energy to live

...nsselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. The work could provide a better understanding of this pathogen, while a...

Ring-around-the-cell

...n microscope imaging that allowed them to see fine details of the ring structure, and a light microscope method in which specific features glow. Because each method captures different information at a different scale, combining them was tricky, but the two together gave a much more extensive picture than eit...

Fruit fly gene research may shed light on human disease processes

..., they can serve as models, allowing us to observe details we can't see in more complex animals." To understand cellular differentiation, Erickson and his graduate students have been researching how fly embryos become male or female, a process that occurs over a 30-minute period early in their development...
