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)
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)
CSHL scientists harness logic of 'Sudoku' math puzzle to vastly enhance genome-sequencing capability
A math-based game that has taken the world by storm with its ability to delight and puzzle may now be poised to revolutionize the fast-changing world of genome sequencing and the field of medical genetics. view more (2009-06-25)
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)
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)
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)
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)
GeneBalls: barcoding DNA
Millions of genetic tests using just one drop of blood. view more (2004-09-10)
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)
MIT particles pave way for new bedside diagnostics
MIT researchers have created an inexpensive method to screen for millions of different biomolecules (DNA, proteins, etc.) in a single sample-a technology that could make possible the development of low-cost clinical bedside diagnostics. view more (2007-03-09)
Detecting the undetectable in prostate cancer screening
A team of Northwestern University researchers, using an extremely sensitive tool based on nanotechnology, has detected previously undetectable levels of prostate-specific antigen (PSA) in patients who have undergone radical prostatectomy. view more (2009-10-20)
Would you like gene chips with your salad ?
The first public release of plant gene chip information is being launched at the Society for Experimental Biology conference in Swansea on Friday 12th April. Scientists from the Nottingham Arabidopsis Stock Centre (NASC), part of a multi-million pound resource network, will announce a newly accessible plant gene chip database which is available... view more...

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)
Flaws in the barcoded technology used to reduce medication administration errors identified
In the first study of its kind, researchers led by The University of Pennsylvania School of Medicine's Ross Koppel, Ph.D. studied how hospital nurses actually use bar-coded technology that matches the right patient with the right dose of the right medication. view more (2008-07-01)
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)
Winning at logistics with a roulette wheel
Employees in post offices spend the entire day sorting parcels and packets of various shapes and sizes. This can now be done by a tireless, reliable and automatic rotating sorting machine resembling a large roulette wheel. A prototype rotates at the Hanover Fair. ---------- Many a workday is dull and monotonous - this is also a common grievance of... view more... (2002-04-16)
Barcode for explosives
Experts encounter a serious problem when studying the crime scene after an explosion. They can establish to a high degree of probability the type and power of the device used by terrorists and with what explosive substance it was filled with. However, they are usually unable to answer the most important question as to where and when the explosive... view more... (2005-03-03)
