Study finds DNA barcoding requires caution without closer examination
The goal of DNA barcoding is to find a simple, cheap, and rapid DNA assay that can be converted to a readily accessible technical skill that bypasses the need to rely on highly trained taxonomic specialists for identifications of the world's biota.   view more (2009-06-25)

DNA barcodes put to the test
With species around the world disappearing faster than biologists can identify them, many scientists pinned their hopes on DNA barcoding, a recently proposed strategy that treats a short fragment of DNA as a sort of universal product code to identify species.   view more (2005-11-29)

Smithsonian scientists help lead effort to 'barcode' world's species
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.   view more (2007-09-17)

New research finds surveys of larval-stage organisms effective for measuring marine biodiversity
There is a push to document the biodiversity of the world within 25 years. However, the magnitude of this challenge is not well known, especially when it comes to vast and often inaccessible marine environments.   view more (2006-05-15)

Barcoding endangered sea turtles
Conservation geneticists who study sea turtles have a new tool to help track this highly migratory and endangered group of marine animals: DNA barcodes.   view more (2009-09-15)

Study: DNA barcoding in danger of 'ringing up' wrong species
DNA barcoding is a movement to catalog all life on earth by a simple standardized genetic tag, similar to stores labeling products with unique barcodes. The effort promises foolproof food inspection, improved border security, and better defenses against disease-causing insects, among many other applications.   view more (2008-08-26)

Unknowlingly consuming endangered tuna
While most of us would never willingly consume a highly endangered species, doing so might be as easy as plucking sushi from a bento box.   view more (2009-11-20)

CU-Boulder team identifies DNA barcodes to help track illegal trading of wildlife products
Researchers from several institutions including the University of Colorado at Boulder have sequenced DNA "barcodes" for as many as 25 hunted wildlife species, providing information that can be used to better monitor the elusive trade of wildlife products, or bushmeat.   view more (2009-09-16)

New light trap captures larval stage of new species; DNA barcode technology used
When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami's Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the discovery of a new species.   view more (2007-10-24)

NOAA Researchers Help Build a Global Reference Library of DNA Barcodes
Most of us are familiar with bar codes, those small black stripes with numbers below, known as the Universal Product Code or UPC label, that appear on commercial products. We scan them at the grocery store or to check a price, or have to cut them out and send them in for a rebate.   view more (2008-04-21)

The first DNA barcodes of commonly traded bushmeat are published
Leather handbags and chunks of red meat: when wildlife specialists find these items in shipping containers, luggage, or local markets, they can now use newly published genetic sequences known as "DNA barcodes" to pinpoint the species of origin.   view more (2009-09-08)

Protein binds whenever it can
Dutch cancer researcher Joost Martens has discovered that the protein p300, which plays an important role in the correct transcription of DNA to RNA, can bind to DNA at several sites. The protein can also occupy a position in various complexes, each with its own protein composition. This knowledge is important for gaining a better understanding of... view more... (2003-06-24)

A better way to copy DNA
Scientists have developed a new method for DNA amplification that could replace the polymerase chain reaction (PCR), a technique that is invaluable for both medical diagnostics and basic research but which is confined to the laboratory. In the August issue of EMBO reports, Huimin Kong and colleagues at New England Biolabs (Beverly, MA, USA)... view more... (2004-07-14)

Few clues about African ancestry to be found in mitochondrial DNA
Mitochondrial DNA may not hold the key to your origins after all. A study published today in the open access journal BMC Biology reveals that fewer than 10% of African American mitochondrial DNA sequences analysed can be matched to mitochondrial DNA from one single African ethnic group.   view more (2006-10-12)

DNA barcodes: Creative new uses span health, fraud, smuggling, history, more
The scientific ability to quickly and accurately identify species through DNA "barcoding" is being embraced and applied by a growing legion of global authorities - from medical and agricultural researchers to police and customs authorities to palaeontologists and others.   view more (2009-11-09)

Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.   view more (2005-09-30)

U of Alberta study discovers how proteins help repair DNA
A person's DNA is often damaged by a number of different chemical contaminants, and if not repaired properly, it can lead to the development of cancer and other diseases.   view more (2009-06-16)

Dual enzymatic activity of RECQ1 explained by different quaternary structures
The transient opening of the DNA double helix is a fundamental step in several DNA metabolic processes. This reaction is driven by proteins called helicases, which make use of ATP as fuel to unwind the DNA duplex.   view more (2007-01-16)

UBC scientists find new way to extract diluted and contaminated DNA
University of British Columbia researchers have developed a new way to extract DNA and RNA from small or heavily contaminated samples that could help forensic investigators and molecular biologists get to "the truth."   view more (2009-08-11)

Researchers Find Synthetic Molecules That May Literally Be The Key To “Locking Away” Unwanted DNA
Research chemists have a found a class of synthetic molecules that could quite literally act as a key which could lock away sections of DNA into a closely wound coil preventing proteins from interacting with particular sections of DNA code. By locking up the DNA in this way scientists could stop particular sequences of DNA from activating... view more... (2002-04-15)
