Scientists sequence genome of parasite responsible for common sexually transmitted infection

...ience. "The progress that continues to be made in deciphering the genomes of organisms, such as the Trichomonas vaginalis parasite, helps to further our collective scientific understanding of these organisms, so that we can better address public health issues," says NIH Director Elias A. Zerhouni, M.D. "By b...

Prehistoric mystery organism verified as giant fungus

...egible scrawl," Hotton said. "Fran spent months deciphering them for clues about the localities where specimens had been collected, how Dawson interpreted them and other information that helped understand this humongous fungus," she said. Hueber also traveled to Canada, Australia and Saudi Arabia to collec...

Comprehensive model is first to map protein folding at atomic level

...es. "One of the great problems in science has been deciphering how amino acid sequence -- a protein's primary structure -- also determines its three-dimensional structure, and through that its biological function. Our paper provides a first solution to the folding problem, for small proteins, at an atomic level ...

Computer scientists unravel 'language of surgery'

...rgical tasks such as suturing, a key first step in deciphering the language of surgery. The lead author, Johns Hopkins graduate student Henry C. Lin, received the conference award for best student paper. "Now, we're acquiring enough data to go from ‘words' to ‘sentences,'" said Hager, who is deputy director of...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...r bottleneck in research caused by difficulties in deciphering the actions of a heat-shock protein known as Hsp90. Hsp90 belongs to a family of proteins called chaperones that help other proteins achieve and maintain their 3-D structure. Unlike most chaperones, Hsp90 is dedicated to assist a restricted yet di...

Viral hitchhiker inhibits Wolbachia bacteria's ability to proliferate

...dings because there is a great deal of interest in deciphering the genetic and cytological mechanisms of cytoplasmic incompatibility," says Bordenstein. "We know very little about the virus, but understanding and using it may pave the way for future strategies to control insect-borne diseases." ...

UF scientists discover evolutionary origin of fins, limbs

... has been known for some time, but only now are we deciphering how these events occurred at a molecular genetic level." Researchers isolated genes from the spotted catshark, a type of slow-moving shark from the eastern Atlantic Ocean. By studying the activity of a dozen genes in shark embryos, they determined ...

Scientists crack code for motor neuron wiring

...ic that there will eventually be clinical value in deciphering the Hox code. "In developing ways to recover from spinal cord injuries, much attention has focused on getting the axons of cortical neurons to grow past the lesion site and innervate target neurons in distant parts of the spinal cord," he said. "Now,...

First big influenza genome study reveals flu evolution

...s turns a new spotlight on influenza evolution. By deciphering the genomes of different influenza strains, researchers can pinpoint mutations that allow particular strains to become more virulent, adapt to infect new species, or evade immune response. Moreover, TIGR's high-throughput influenza genome sequencin...

Researchers predict infinite genomes

...s revolution took off, scientists have been busily deciphering vast numbers of genomes. Cataloging. Analyzing. Comparing. Public databases hold 239 complete bacterial genomes alone. But scientists at The Institute for Genomic Research (TIGR) have come to a startling conclusion. Armed with the powerful tools of ...

Achilles heel of the herpes virus possibly found

...many possibilities for virus binding to cells make deciphering the entry process a difficult problem to solve. The gene that encodes B5 had in fact been sequenced, but not characterized, as part of the Human Genome Project. Discovering its role and studying the HSV entry mechanism was tricky and near impossible...

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be pub...

Deep thinking: Scientists sequence a cold-loving marine microbe

...uropa. As yet, however, there's little chance that deciphering C. psychrerythraea's genome will yield insights into another cool character, its namesake. Deming, who led the establishment of the Colwellia genus, named the genus after her one-time advisor: noted marine biologist Rita Colwell. In addition the TIG...

The biggest family tree ever

...a population geneticist. One of his specialties is deciphering prehistoric human relationships using genetics. By comparing the genetic markers, the UA scientists' work will unveil new aspects of people's family trees, ones that are almost impossible to discover through traditional genealogical methods. In cont...

Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

... to our understanding of protein synthesis; to the deciphering of the genetic code by which hereditary information is stored and transcribed in the cell; and to our conception of the human brain. Francis Harry Compton Crick was born in Northampton, England, in 1916, and received his bachelor degree in physics f...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...th a huge amount of data, and the daunting task of deciphering what it means in terms of how genes function. For that part of the project, they teamed with investigators from the Broad (pronounced to rhyme with "road") Institute. "The human genome still has many surprises lurking within it," comments Lander, wh...

Color-blind method opens new doors in DNA sequencing

.... Even with complex computer programs to assist in deciphering the signals, this "cross-talk" between the dyes results in subtle variations that can cause nucleotides to be miscalled. The new method developed at BCM and Rice, called pulsed multiline excitation, uses four lasers, each matched to a particular dye...
