Garlic Helps Protect Our DNA
Mutagens damage DNA. Consequently, antimutagens have to repair these damages. As the effects on DNA differ, the ways of reparation also vary. However, the mechanism of the activity of some antimutagens has not been found yet. A team headed by Professor G.D. Zasukhina at N.I. Vavilov Institute of General Genetics (http://www.vigg.ru/vigg-en.htm),... view more... (2002-06-07)
Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different? view more (2007-03-28)
Genetic double-agents unmasked
Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer. view more (2004-10-26)
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)
Researchers discover RNA repair system in bacteria
In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria. view more (2009-10-13)
Study reveals why certain ovarian cancers develop resistance to platinum-based chemotherapy
A team of researchers led by Fred Hutchinson Cancer Research Center has identified a new mechanism that explains why some recurrent ovarian tumors become resistant to treatment with commonly used platinum-based chemotherapy drugs such as cisplatin and carboplatin. They describe their research online Feb. 10 in the journal Nature. view more (2008-02-11)
Harvard researchers publish MRI images of genes in action in the living brain
Biologists have just confirmed what poets have known for centuries: eyes really are windows of the soul-or at least of the brain. view more (2008-03-31)
Tumor mutations can predict chemo success
New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy. view more (2009-08-07)
Enzyme alerts cell's powerful army to repair DNA damage
Scientists know that inside each cell, a little engine called RNA polymerase II does one essential job: It copies instructions from genes in the nucleus that get carried to production units in the rest of the cell to support our daily needs. view more (2007-09-06)
Protein's essential role in repairing damaged cells revealed
University of Michigan researchers have discovered that a key protein in cells plays a critical role in not one, but two processes affecting the development of cancer. view more (2009-01-07)
Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer. view more (2008-11-21)
Common Enzyme is a Key Player in DNA Repair
A quarter century after they discovered it, researchers have identified the job of one of the most common DNA-damage response proteins. view more (2006-01-12)
Scripps scientists uncover mimicry at the molecular level that protects genome integrity
The new study, which was published on April 12, 2009, in an advanced online edition of the journal Nature Structural & Molecular Biology, draws new parallels between the Rad60 DNA repair factor and SUMO, a small ubiquitin-like modifier, which are both essential for maintaining genome stability during replication. view more (2009-04-14)
Regaining Hand Control After Nerve Damage
A Swedish study published as a research letter in this week’s issue of THE LANCET concludes that the return of sensory control in the hand after nerve damage in the arm is an age-related learning process involving the central nervous system, and is similar to the processes involved in language acquisition. One of the challenges in... view more... (2001-09-05)
New research suggests a potentially damaging effect of extremely low frequency electromagnetic fields
The effect of extremely low frequency electromagnetic fields (ELF-EMF), such as those emitted around high-voltage transmission lines on human health, is controversial. Some studies suggest an association between exposure to ELF-EMF and incidence of leukaemia, although little direct evidence exists that exposure causes damage to biological... view more...

Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
Biologists discover link between CGG repeats in DNA and neurological disorders
Researchers have long known that some repetitive DNA sequences can make human chromosomes "fragile," i.e. appearing constricted or even broken during cell divisions. view more (2009-01-12)
UC Davis researchers discover genetic switch involved in cells' response to radiation therapy
UC Davis Cancer Center researchers have discovered a genetic switch that causes cancer cells to become more sensitive to a drug administered to enhance radiation therapy effectiveness. view more (2005-11-17)
When smell cells fail they call in stem cell reserves
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. view more (2007-04-30)
Finding that 1-in-a-billion that could lead to disease
Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. view more (2007-08-20)
