Electronic structure of DNA revealed for 1st time by Hebrew University and collaborating researchers
Utilizing a technique that combines low temperature measurements and theoretical calculations, Hebrew University of Jerusalem scientists and others have revealed for the first time the electronic structure of single DNA molecules. view more (2008-02-29)
Gene packaging tells story of cancer development
To decipher how cancer develops, Johns Hopkins Kimmel Cancer Center investigators say researchers must take a closer look at the packaging. view more (2008-12-05)
New step in DNA damage response in neurons discovered
Researchers have identified a biochemical switch required for nerve cells to respond to DNA damage. view more (2009-01-20)
Ring-like formations in drying DNA drops could affect hybridization studies
Coffee drinkers are familiar with the ring-shaped stains that result from spilled drops that have dried, in which the brown stain is not evenly distributed, but instead concentrated at the edge. view more (2006-05-12)
Revealing the evolutionary history of threatened sea turtles
It's confirmed: Even though flatback turtles dine on fish, shrimp, and mollusks, they are closely related to primarily herbivorous green sea turtles. view more (2008-10-16)
New study rebuts claims about Icelandic genetic heterogeneity
There has been some controversy in the media and within the scientific research community concerning whether Icelanders are genetically homogenous or heterogeneous relative to other European populations. Following an article published in Annals of Human Genetics in January 2003 by E. 'rnason, who concluded that Icelanders were one of the most... view more... (2003-08-19)
Trichoplax genome sequenced -- 'rosetta stone' for understanding evolution
Yale molecular and evolutionary biologists in collaboration with Department of Energy scientists produced the full genome sequence of Trichoplax, one of nature's most primitive multicellular organisms, providing a new insight into the evolution of all higher animals. view more (2008-09-04)
Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. view more (2008-09-24)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
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)
Upside-down world: DNA protecting protein helps cancer drug to kill cells
Some DNA repair enzymes can become double-edged swords - If they work too slowly, they can block necessary cell maintenance and contribute to cell death. view more (2009-04-28)
Scientists reveal DNA-enzyme interaction with first ever real time footage
For the first time scientists have been able to film, in real-time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. view more (2007-09-18)
Draft version of the Neanderthal genome completed
The Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, and the 454 Life Sciences Corporation, in Branford, Connecticut, will announce on 12 February during the 2009 Annual Meeting of the American Association for the Advancement of Science (AAAS) and at a simultaneous European press briefing that they have completed a first... view more...

New technique for cancer screening
Current research suggests that a new technique to determine tumor methylation status can be used in archived tissue samples. view more (2009-02-24)
DNA test shows promise for identifying patients with colorectal cancer (p 1283)
Testing for DNA changes in stools might provide a new, accurate, and less invasive way to screen patients for colorectal cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Colorectal cancer is one of the most common cancers in the industrialised world, and early detection might help to reduce the risk of death... view more... (2004-04-14)
Foxes get frisky in the far north
Bees do it, chimps do it- Now it seems Arctic foxes do it, too. New research looking at the DNA fingerprints of canids in the Far North has revealed that foxes once thought to be monogamous are in fact quite frisky. view more (2007-07-18)
Evolutionary conservation of a mechanism of longevity from worms to mammals
Though the study of aging in the nematode model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. view more (2005-10-05)
DNA size a crucial factor in genetic mutations, study finds
Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA. view more (2005-10-27)
A potential approach to treatment of hepatitis B virus infection
Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA. view more (2008-09-10)
Hippo ancestry disputed
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy. view more (2009-03-19)
