Scientists reveal how biological activity is regulated in fruit fly and roundworm genomes Thursday, December 23, 2010 - 00:00
Scientists today published catalogs of the fruit fly and roundworm's functional genomic elements: DNA sequences in the genome that carry the instructions and determine which genes are turned on and of
Carnegie Mellon Researchers Discover Mechanism for Cell Receptor Recycling Thursday, December 23, 2010 - 00:00
Discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a s
Genome sequence of 50,000 year old finger bone connect to present-day human Wednesday, December 22, 2010 - 00:00
The genome of the bone found in Denisova cave in 2008 in Southern Siberia is now sequenced. The Denisova bone belonged to a female and is considered to be 30000-50,000 years old. The results publish
Scientists decipher 3 billion-year-old genomic fossils Monday, December 20, 2010 - 00:00

MIT scientists have created a sort of genomic fossil that shows that the collective genome of all life underwent an enormous expansion about 3 billion years ago, which they're calling the Archean Expa
