The cure for cancer comes down to this: video games. In a research lab at Wake Forest University, biophysicist and computer scientist Samuel Cho uses graphics processing units (GPUs), the technology that makes videogame images so realistic, to simulate the inner workings of human cells. "If it wasn't for gamers who kept buying these GPUs, the prices wouldn't have dropped, and we couldn't have used them for science," Cho says. Now he can see exactly how the cells live, divide and die....

It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of 'letters' in even a small genome? New work by researchers at the University of California, Davis, handling and observing single molecules of DNA, shows how it's done. The results are published online Feb. 8 by the journal Nature. Defects in DNA repair and copying are strongly...

Scientists have found at least one instance when the smaller sibling gets to call the shots and cancer patients may one day benefit. The protein Chk1 has long been known to be a checkpoint in cell development: it keeps normal cells and damaged cells from dividing until their DNA has been fully replicated or repaired. Now scientists at Georgia Health Sciences University and the California Institute of Technology have discovered a shorter form they've dubbed Chk1-S ("S" stands for short)...

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies. To visualize the synthesis of...

Researchers have revealed how a molecule called telomerase contributes to the control of the integrity of our genetic code, and when it is involved in the deregulation of the code, its important role in the development of cancer. The University of Montreal scientists involved explain how they were able to achieve their discovery by using cutting edge microscopy techniques to visualize telomerase molecules in real time in living cells in Molecular Cell on December 9, 2011. "Each time our...

Shortening end caps on chromosomes in human cervical cancer cells disrupts DNA repair signaling, increases the cells´ sensitivity to radiation treatment and kills them more quickly, according to a study in Cancer Prevention Research. Researchers would to like see their laboratory findings — published in the journal´s Dec. 5 print edition — lead to safer, more effective combination therapies for hard-to-treat pediatric brain cancers like medulloblastoma and high-grade...

Understanding the endocycle has implications for agriculture and medicine An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass. This discovery, led by a geneticist at Fred Hutchinson Cancer Research Center and reported Oct. 30 in Nature, leads to a new...
