New bird, bat species revealed by extensive DNA barcode studies
02-18-2007 · EurekAlert!At unprecedented levels of difficulty involving highly biodiverse and continent-sized landscapes, scientists have successfully tested their ability to identify and DNA "barcode" entire assemblages of species -- the prelude to a genetic portrait of all animal life on Earth.

- Amid spiralling government interest, world's top 350 DNA barcode scientists meet in Taipei
09-14-2007 · EurekAlert!
Amid spiralling interest from health officials, government agencies and others beginning to realize potential applications of DNA barcoding, experts from 46 nations converge in Taipei Sept. 18-20.Among many other things, barcoding could help remove illegal fish and timber from global markets, slow the spread of invasive pests, reduce bird-plane collisions, and uncover the hideouts of medically-important mosquito species.

- The wider view from a detailed focus
06-13-2007 · EurekAlert!
A major study of the organization and regulation of the human genome published today changes our concept of how our genome works. The exhaustive analysis of 1 percent of the genome gives an extensive view of genetic activity alongside the cellular machinery that allows DNA to be read and replicated. The complex tapestry of interwoven elements revealed today suggests that "our perspective of transcription and genes may have to evolve," the researchers state.

- Researchers barcode DNA of Venice museum's vast fungi collection
12-15-2006 · EurekAlert!
UC Berkeley researchers are partnering with the Venice Museum of Natural History to build an unprecedented DNA database of its vast fungi collection. More than 6,000 species will be sequenced and analyzed, and then made available to the scientific community.

- Genomic variation easier to identify with UCSD/Brown software
12-22-2006 · EurekAlert!
Computer scientists at the University of California, San Diego, and Brown University have created a software system that more accurately detects "microinversions," mutations that consist of tiny sequences of reversed DNA. The software gives biologists a powerful new tool to study genomic variation between and within species. The system is explained in the online edition of the Proceedings of the National Academy of Sciences.

- Surgical biopsy may reveal cancer in women with rare but benign breast condition
11-10-2006 · EurekAlert!
A study at Washington University School of Medicine in St. Louis showed that in women whose initial breast biopsies revealed certain rare, yet benign breast conditions, more extensive follow-up surgical biopsies found cancer up to 25 percent of the time. Most of the cancers were invasive, meaning the tumors had penetrated normal breast tissue and would require treatment.

- Ecologists discover city is 'uber-forest' for big owls
10-16-2007 · EurekAlert!
Charlotte has a spooky secret: the North Carolina city is home to a robust population of very large barred owls -- a species long-believed by ornithologists to require old growth forest for survival. According to ecologists doing the most extensive field study ever done on the species, the owls see urban life as an upgrade on the old woods, and Charlotteans are not at all creeped out by the big birds that share their yards.

- Genetic roots of bipolar disorder revealed by first genome-wide study of illness
05-08-2007 · EurekAlert!
Several specific genes are implicated in bipolar disorder. This was the first genome-wide "association" study of the illness. Association studies help determine if specific diseases are associated with genes. One of the genes implicated produces a protein that could be a target for developing better medications for the disorder.

- Fish species plays surprise role in aiding coral reef recovery
12-18-2006 · EurekAlert!
In a study that marks progress in understanding the basis of coral reef recovery, researchers have revealed the critical importance of a rare batfish, Platax pinnatus, in promoting the return to health of a disturbed coral reef overgrown with algae. The findings bring to light a previously unrecognized role for the batfish species, which had not been considered a significant player in reef recovery after overfishing.

- Student study bolsters case for adding a rare sunflower to the endangered species list
09-11-2007 · EurekAlert!
A native species of sunflower, called the giant whorled sunflower, is only known to exist in four locations in the Southeast United States. In the last four years, Vanderbilt graduate student Jennifer Ellis has conducted a series of genetic studies that significantly increase the odds that this gangly plant will be placed on the endangered species list.

- Smithsonian scientists help lead effort to 'barcode' world's species
09-16-2007 · EurekAlert!
Smithsonian researchers are among the leaders in a worldwide effort to revolutionize the way scientists identify species in the laboratory and in the field with a technique called DNA barcoding. Similar to the barcode that identifies an item at the grocery store, a DNA barcode is used to identify and distinguish biological species.
