NIH neuroscience microarray consortium launches high-throughput genotyping services

...ess to a full range of microarray technologies for scanning the entire human genome and all of the genes for which it encodes." Each of the four members of the Consortium offer specialized services. The Translational Genomics Research Institute (TGen) offers both expression profiling and SNP genotyping on ...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

... Celera colleagues developed the test by initially scanning the DNA of more than 1,000 people who had hepatitis C. Out of 25,000 genetic variations tested, the researchers discovered seven that could be used together as a "signature" for predicting progression to cirrhosis in Caucasians. The resulting ...

Nanoparticles can track cells deep within living organisms

...usual meal, the cells were easily located with MRI scanning after being injected into mice. Developed in the laboratories of Samuel A. Wickline, M.D., and Gregory Lanza, M.D., Ph.D., the nanoparticles could soon allow researchers and physicians to directly track cells used in medical treatments using unique...

Walking molecule now carries packages

...hemical formula is C14H8O2. The UCR study used a scanning tunneling microscope in Bartels's laboratory that gives a precise picture of individual molecules. Experiments took place on a highly polished copper surface, cleaned so that only the desired molecules were present on it. An individual anthraquinone ...

Stretching DNA to the limit

...pick up individual DNA molecules with the tip of a scanning probe microscope and stretch it while measuring the forces generated. These "stretch—release" measurements enable the accurate determination of changes in the elasticity of the DNA strands. Upon exposure to UV light, the force profile of the viral DN...

Tiny clue reveals new path toward heart disease

...experiment in four additional patient populations, scanning the DNA of a total of 4,000 individuals, and turned up the same result. "This finding opens up a whole new area of study for looking at risks of cardiovascular disease," said senior study investigator Jeffrey M. Vance, M.D., Ph.D., director of th...

Susceptibility to Crohn's disease -- an important new clue

...ing technology have allowed systematic association scanning of the entire genome for the detection of novel susceptibility loci ?fixed positions on a chromosome, such as the position of a gene. Libioulle and colleagues applied this approach to Crohn’s disease and identified the key locus on chromosome 5. I...

No sex for 40 million years? No problem

... DNA sequencing and jaw measurements taken using a scanning electron microscope, the research team examined bdelloid rotifers living in different aquatic environments across the UK, Italy and other parts of the world. They found genetic and jaw-shape evidence that the rotifers had evolved into distinct specie...

Trusting your instincts leads you to the right answer

...ting of the eye is often an essential subconscious scanning technique that allows us to pick out unique and distinctive features in a crowd ?such as colour or orientation. Soon after our eyes have fixed on a target, the conscious or top-down part of cognition engages and examines whether the candidate really ...

Technology reveals 'lock and key' proteins behind diseases

... interfering with this process." iMYTH works by scanning cells to reveal proteins that fit with the transporters, the only screening system sophisticated enough to work with delicate membrane proteins. Simply, if two proteins interact in iMYTH, they will stain the yeast cell blue. "Like lock and key, if tw...

World's leading scientists announce creation of 'Encyclopedia of Life'

Diminishing dinosaur steps saved by laser and laptop

...cutting-edge equipment. Using a high-tech laser scanning system called RIEGL, researchers from The School o...had to taken remotely. Dr Manning added: "Laser scanning allowed the rapid, high resolution, 3D digital mapping of an otherwise inaccessible site. The comput...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...he entire group at a small fraction of the cost of scanning each person's material individually. The genetic material of the healthy group was pooled and scanned separately, again at a fraction of the cost of individual scans. The researchers then zeroed in on the gene variations that occurred more often in...

Scientists discover 5 new species of sea slugs from the Tropical Eastern Pacific

...ng collections, consulting specialists and using a scanning electron microscope to examine the jaws and other hard parts of the nudibranchs that distinguish species. This was part of the formal project “Phylogenetic Systematics of Nudibranchia,” sponsored by a National Science Foundation grant to Terrence ...
