SLU Researchers Uncover Direct Evidence on How HIV Invades Healthy Cells
Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV. view more (2005-12-22)
New nanosensor uses quantum dots to detect DNA
Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. view more (2005-12-06)
Taking aim at mysterious DNA structures in the battle against cancer
Designers of anti-cancer drugs are aiming their arrows at mysterious chunks of the genetic material DNA that may play a key role in preventing the growth and spread of cancer cells, according to an article in the current issue of Chemical & Engineering News, ACS' weekly newsmagazine. view more (2009-11-05)
Seemingly suicidal stunt is normal rite of passage for immune cells
Researchers have shown that self-induced breaks in the DNA of immune cells known as lymphocytes activate genes that cause the cells to travel from where they're made to where they help the body fight invaders. view more (2008-10-21)

DNA Anniversary Poster
2003 is the 50th anniversary of one of the most important breakthroughs in science - the discovery of the DNA double helix by James Watson and Francis Crick in Cambridge in the spring of 1953. A photograph of the pair with their original model of DNA, taken in May 1953 by Antony Barrington Brown, has become an icon of scientific discovery, marking... view more... (2003-02-07)
Baumann Lab demonstrates role of protein in distinguishing chromosome ends from DNA breaks
The Stowers Institute's Baumann Lab has demonstrated how human cells protect chromosome ends from misguided repairs that can lead to cancer. view more (2009-09-18)
Press Briefing - Leading scientists explore the next 50 years of DNA related research
Leading international scientists in the field of molecular biology will be attending a scientific discussion meeting entitled 'Replicating and reshaping DNA: a celebration of the jubilee of the double helix' at the Royal Society on 23rd and 24th April 2003. The meeting will look at the cutting edge of today's science of DNA and how the intricate... view more... (2003-04-16)
Research breakthrough targets genetic diseases
A cure for debilitating genetic diseases such as Huntington's disease, Friedreich's ataxia and Fragile X syndrome is a step closer to reality, thanks to a recent scientific breakthrough. view more (2009-01-21)
Once suspect protein found to promote DNA repair, prevent cancer
An abundant chromosomal protein that binds to damaged DNA prevents cancer development by enhancing DNA repair, researchers at The University of Texas M. D. Anderson Cancer Center report online this week in the Proceedings of the National Academies of Science. view more (2008-07-22)
Molecule crucial for processing non-coding RNA identified
The discovery in 1977 that the coding regions of a gene could appear in separate segments along the DNA won the 1993 Nobel Prize in Physiology or Medicine for Richard J. Roberts and Phillip A. Sharp. view more (2005-10-21)
Fungi can tell us about the origin of sex chromosomes
Fungi do not have sexes, just so-called mating types. A new study being published today in the prestigious journal PLoS shows that there are great similarities between the parts of DNA that determine the sex of plants and animals and the parts of DNA that determine mating types in certain fungi. view more (2008-03-18)
Just a little squeeze lets proteins assess DNA
To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research from The University of Arizona in Tucson. view more (2008-12-17)
Short sugar chains--a future drug for Alzheimer's?
Heparansulfate, which is needed for normal fetal development among other things, is also important for the build-up of amyloid, morbid protein deposits that appear in several serious diseases. This is shown by Uppsala scientists in an article published in today's Net edition of the U.S. journal Proceedings of the National Academy of Science.... view more... (2005-04-19)
Penn researcher shows that DNA gets kinky easily at the nanoscale
Scientists have answered a long-standing molecular stumper regarding DNA: How can parts of such a rigid molecule bend and coil without requiring large amounts of force? view more (2006-11-06)
Cancer cells suppress large regions of DNA by a reversible process that can be tackled
Cancer researchers at Sydney's Garvan Institute, in collaboration with Spanish scientists, have formulated a new concept for how cancer cells can escape normal growth controls, which may have far-reaching implications for the new generation of cancer therapies. view more (2006-04-24)
Scientists present the largest-to-date genetic snapshot of Iceland 1,000 years ago
Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors. view more (2009-01-16)
Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today. view more (2007-02-23)
ASU researchers 'wire' DNA to identify mutations
A team of ASU researchers led by Nongjian Tao and Peiming Zhang has developed a new, breakthrough technique for the detection of DNA mutations. view more (2005-12-09)
Study identifies several new bacterial species associated with common infection in women
Despite being one of the most common infections among women, scientists and doctors know little about the causes of bacterial vaginosis (BV), a usually benign disease that is also linked to serious health problems including pelvic inflammatory disease. view more (2005-11-03)
