New study suggests Concord grape juice may provide protection against breast cancer
Every three minutes, a woman in the United States is diagnosed with breast cancer . While factors like age and heredity contribute significantly to a woman's likelihood of contracting this disease, lifestyle and nutrition choices may also play a role. view more (2007-08-10)
IUPUI scientists report first 3-D view of anti-cancer agent
Researchers from the Indiana University School of Medicine and the Purdue School of Science at Indiana University-Purdue University Indianapolis have created the first three-dimensional image of how a well-established chemotherapy agent targets and binds to DNA. view more (2008-03-19)
Enhanced DNA-repair mechanism can cause breast cancer
Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery. view more (2007-10-15)
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)
Scientists 'rebuild' giant moa using ancient DNA
Scientists have performed the first DNA-based reconstruction of the giant extinct moa bird, using prehistoric feathers recovered from caves and rock shelters in New Zealand. view more (2009-07-02)
Researchers reveal structure of protein that repairs damage to cancer cells
A team of University of Chicago scientists has shown how two proteins locate and repair damaged genetic material inside cells. view more (2008-04-24)
Researchers probe a DNA repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA. Enzymes called helicases play a key role in human health, according to Maria Spies, a University of Illinois biochemistry professor. view more (2008-02-19)
New information about DNA repair mechanism could lead to better cancer drugs
Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. view more (2009-07-17)
Preventing spinal cord injury during aortic surgery
Surgery to repair aortic aneurysms often comes with a high price: neurological deficits, but new research points to a possible defense against spinal cord injury during aortic surgery. view more (2006-06-22)
Important new model shows how proteins find the right DNA sequences
Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes. view more (2009-03-16)
New evidence shows Rituximab halts damage to joints
New data, presented today at the Annual European Congress of Rheumatology show for the first time that a rheumatoid arthritis (RA) treatment, rituximab, is able to significantly inhibit the structural damage to joints caused by RA in patients who have long-standing disease and an inadequate response to one or more TNF (Tumour Necrosis Factor)... view more...

Cutting calories slightly can reduce aging damage
A lifelong habit of trimming just a few calories from the daily diet can do more than slim the waistline-a new study shows it may help lessen the effects of aging. view more (2006-05-09)
Finding a cure for cancer: the holy grail of science
To find a cure for cancer, the modern-day plague of our society - is synonymous to finding the holy grail of science. view more (2006-11-22)
Novel DNA vaccine leads to kidney damage prevention in systemic lupus erythematosus models
DNA vaccination using lupus autoantigens and interleukin-10 (IL-10, a cytokine that plays an important role in regulating the immune system) has potential as a novel therapy to induce antigen specific tolerance and may help to prevent kidney damage in patients with systemic lupus erythematosus (SLE). view more (2009-06-12)
DNA’s oscillating double helix hinders electrical conduction
DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the devices the researchers from Amsterdam used to demonstrate this. It turns out the DNA does not have a rigid regular structure as stated in textbooks. In... view more... (2002-09-11)
Protein complex key in avoiding DNA repair mistakes, cancer
As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows. view more (2009-08-05)
Immune system response to viral DNA is unique
The human body has a unique immune system response to foreign DNA, suggesting that DNA viruses and RNA viruses are detected by different mechanisms. view more (2006-01-25)
Human DNA repair process recorded in action
A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about the role played by a protein known as Rad51, which is linked to breast cancer, in this complex and critical process. view more (2009-01-29)
New test can rule out heart damage within six hours
A new test to assess chest pain in UK emergency departments can rule out the possibility of heart damage within six hours, allowing safe discharge of patients and reducing unnecessary admissions, finds a study in this week's BMJ. The current approach requires admission to hospital for a minimum of 24 hours. Over a 12-month period, researchers at... view more... (2001-08-15)
Researchers uncover new mechanism of tumor suppressor
Researchers from the University of Colorado-Denver and Health Sciences Center and Stanford University have discovered a molecular mechanism that explains how cells respond to DNA damage and other acute stresses, and if disrupted can cause cancer. view more (2006-05-22)
