Fruit fly study advances genetics (11/17/2007)

The humble fruit fly has played a lead role on the scientific stage for more than a century. Tiny picnic pests to us, flies from a single species, Drosophila melanogaster, have provided a bounty of Nobel Prize-winning discoveries for researchers in the fields of genetics and developmental biology, and helped serve as models of human diseases such as Parkinson's and cancer. ...> Full Article

Domestic Cat Genome Sequenced (11/2/2007)

The DNA of a 4-year-old Abyssinian cat named Cinnamon, whose well-documented lineage can be traced back several generations to Sweden, has been sequenced. Cinnamon is one of several mammals that are currently being analyzed using "light" (two-fold) genome sequence coverage. To make sense of Cinnamon's raw sequence data, a multi-center collaboration of scientists leveraged information from previously sequenced mammalian genomes as well as previous gene-mapping studies in the cat. In doing so, they found that Cinnamon's sequences spanned about 65% of the euchromatic (gene-containing) regions of the feline genome. ...> Full Article

Individual Differences Caused by Shuffled Chunks of DNA in the Human Genome (9/30/2007)

Researchers offer a new view of what causes the greatest genetic variability among individuals - suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged or present in extra copies. ...> Full Article

Research project on rice epigenetics using new techniques (9/11/2007)

Using a novel "deep sequencing" technology that can in one fell swoop decode 50 million sequences representing well over a billion bases of DNA, a research team led by University of Delaware scientists is working to unmask where, why and how certain genes are switched on or off in rice--a crop vital to the world's food supply. ...> Full Article

Comprehensive Gene Sequencing Find Strong Connection Between Virus and Colony Collapse Disorder in Bees (9/9/2007)

A team led by scientists from the Columbia University Mailman School of Public Health, Pennsylvania State University, the USDA Agricultural Research Service, University of Arizona, and 454 Life Sciences has found a significant connection between the Israeli Acute Paralysis Virus (IAPV) and colony collapse disorder (CCD) in honey bees. The findings, an important step in addressing the disorder that is decimating bee colonies across the country, are published in the journal Science this week. ...> Full Article
