Changes in urine could lead to BSE test for live animals (EurekAlert!)
( BioMed Central ) Researchers have demonstrated that protein levels in urine samples can indicate both the presence and progress of Bovine Spongiform Encephalopathy disease in cattle. Publishing their findings in BioMed Central's open access journal Proteome Science, the scientists hope that their discovery might lead to the development of a urine-based test that could prevent the precautionary ...

Studying The Accuracy Of DNA Editing In Mammals (Medical News Today)
Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation.

DNA Editing Tool Flips Its Target (Science Daily)
Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation. Scientists have caught in action one of the tools mammalian cells use to maintain their pattern of methylation. Visualized by X-ray crystallography, ...

Gene enhancer in evolution of human opposable thumb (EurekAlert!)
( Agency for Science, Technology and Research (A*STAR), Singapore ) Scientists have discovered gene enhancer, known as HACNS1, that may have contributed to evolution of uniquely opposable human thumb, and possibly also modifications in ankle or foot that allow humans to walk on two legs, according to paper published in Science Sept. 5, 2008.

DNA editing tool flips its target (EurekAlert!)
( Emory University ) DNA methylation -- a chemical process cells use to tag genes -- is important for keeping certain genes silent. The structure of the SRA domain of UHRF1, a protein that recognizes DNA that is methylated on only one side of the double helix, gives scientists a glimpse of how methylation is maintained during DNA replication. The SRA domain performs the unusual maneuver of ...

Engineers Create Bone That Blends Into Tendons (Kansas City InfoZine)
Engineers at Georgia Tech have used skin cells to create artificial bones that mimic the ability of natural bone to blend into other tissues such as tendons or ligaments. The artificial bones provide for better integration with the body and handle weight more successfully.
