Light activated anticancer drug targeted to DNA using cisplatin like sub-units
One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair. view more (2006-03-27)
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)
HIV inserts into human genome using a DNA-associated protein
A human DNA-associated protein called LEDGF is the first such molecule found to control the location of HIV integration in human cells. view more (2005-11-28)
Brain gene shows dramatic difference from chimp to human
One of the fastest-evolving pieces of DNA in the human genome is a gene linked to brain development. view more (2006-08-17)
Scientists discover a genetic code for organizing DNA within the nucleus
DNA - the long, thin molecule that carries our hereditary material - is compressed around protein scaffolding in the cell nucleus into tiny spheres called nucleosomes. view more (2006-07-20)
Evolution in action? African fish could be providing rare example of forming two separate species, Cornell scientists speculate
Avoiding quicksand along the banks of the Ivindo River in Gabon, Cornell neurobiologists armed with oscilloscopes search for shapes and patterns of electricity created by fish in the water. view more (2006-06-02)
Clawed frog helps Fanconi anemia research make leaps
A large, clawed frog is helping Oregon Health & Science University researchers gather a princely sum of knowledge on Fanconi anemia, a rare, genetic, cancer-susceptibility syndrome. view more (2006-01-25)
New research finds surveys of larval-stage organisms effective for measuring marine biodiversity
There is a push to document the biodiversity of the world within 25 years. However, the magnitude of this challenge is not well known, especially when it comes to vast and often inaccessible marine environments. view more (2006-05-15)
Cigarette smoke blocks cell repair mechanism, University of Florida study shows
Cigarette smoke can turn normal breast cells cancerous by blocking their ability to repair themselves, eventually triggering tumor development, University of Florida scientists report. view more (2006-08-23)
Single nucleotide polymorphisms and forensic genetics, maybe not such a perfect combination
Forensic genetics is the branch of genetics that, through DNA analysis and comparison, deals with the resolution of legal problems such as paternity tests. Recently, it has been proposed that single nucleotide polymorphisms (SNPs) could be used as a new genetic marker in the field eventually even replacing the methods/markers now employed. But in... view more... (2004-10-21)
Novel molecular 'signature' marks DNA of embryonic stem cells
A team of scientists announced today a critical step on the path of realizing the promise of embryonic stem (ES) cells for medicine. view more (2006-04-21)
How a zebra lost its stripes: Rapid evolution of the quagga
DNA from museum samples of extinct animals is providing unexpected information on the extent and effect of the Ice Age as well as the path of species evolution, according to a report by scientists from Yale University, the Smithsonian Institute and the Max Planck Institute for Evolutionary Anthropology. view more (2005-09-27)
Cell survival depends on chromosome integrity
As part of a large National Institutes of Health-funded Technology Centers for Networks and Pathways project, Johns Hopkins researchers have discovered protein machinery important for cells to keep chromosomes intact. view more (2006-07-10)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
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)
New Study Identifies Louse-Borne Diseases That Ravaged Napoleon's Army
Napoleon marched into Russia in the summer of 1812 with a half-million soldiers. Only a few thousand staggered out again, victims of war, weather, and disease. view more (2005-12-15)
Penn researchers determine structure of smallpox virus protein bound to DNA
Researchers at the University of Pennsylvania School of Medicine have determined the structure of an important smallpox virus enzyme and how it binds to DNA. view more (2006-08-07)
New clues for treatment of liver cancer
By generating tumors in laboratory mice that mimic human liver cancer and by comparing the DNA of mouse and human tumors, researchers at Cold Spring Harbor Laboratory have identified two genes that are likely to play a role in the third leading cause of human cancer deaths. view more (2006-06-29)
Animals that seem identical may be completely different species
Animals that seem identical may belong to completely different species. This is the conclusion of researchers at the University of Gothenburg, Sweden, who have used DNA analyses to discover that one of our most common segmented worms is actually two types of worm. The result is one of many suggesting that the variety of species on the earth could... view more... (2009-04-23)
New test to stop illegally logged timber
SMUGGLERS and burglars could now be trapped by something as innocuous as a wood shaving. Forensic scientists have found a way to DNA fingerprint wood, and their discovery could help track illegally logged timber or place a suspect at a crime scene. Forensic botany is increasingly helping to solve... view more... (2002-05-08)
