P(acman) takes a bite out of deciphering Drosophila DNA
11-30-2006 · EurekAlert!A new method of introducing DNA into the genome of fruit flies promises to transform the ability of scientists to study the structure and function of virtually all the fly's genes, and the method may be applicable to other frequently studied organisms such as mice.

- Exploring the dark matter of the genome
06-14-2007 · EurekAlert!
"Junk DNA" is what biologists used to call heterochromatin, the highly repetitive, gene-poor DNA concentrated near the centromeres and telomeres of chromosomes. With the publication of version 5.1 of the genome of the fruit fly, Drosophila melanogaster, led by scientists at Lawrence Berkeley National Laboratory and their colleagues, the term "junk" will be heard less often. Heterochromatin, it appears, is crucial to genome maintenance and cell biology.

- Scientists complete DNA sequencing and analysis of multiple fruit fly genomes
11-07-2007 · EurekAlert!
In one of the first large-scale comparisons of multiple animal genomes, scientists have analyzed the genomes of 12 species of the fruit fly Drosophila, 10 of which were sequenced for the first time, to reveal insights on the evolution of genes and genomes and to discern the functional elements encoded in animal DNA.

- Alternative Energy: New Way To Take A Bite Of Sunlight
10-05-2006 · ScienceDaily
Flash those pearly whites in a dazzling smile and you showcase a natural light collector mechanism hidden inside the internal structure of dentin - the hard, bone-like material that forms the main part of teeth. Scientists in Germany are reporting that the photonic crystal structure of dentin was their inspiration to propose a new method for harvesting sunlight to produce electricity.

- New study shows how genetic repair mechanism helps seal DNA breaks
10-19-2006 · EurekAlert!
A new study by researchers from the Scripps Research Institute, Lawrence Berkeley National Laboratory, the Washington University School of Medicine and the University of Maryland has provided a clearer picture of the final steps of a critical DNA repair process. When these repair processes go awry, cells can malfunction, die or become cancerous.

- Sea urchin genome is a biology boon and a computational feat
11-09-2006 · EurekAlert!
Now that the entire DNA map of the sea urchin is complete, it's clear that these spiny sea creatures are even closer genetic cousins to humans than suspected. Brown University professors Gary Wessel and Sorin Istrail helped reveal the secrets of the urchin -- from its powerful immune system to its formidable gene regulatory network -- by identifying individual genes and creating the first high-resolution map of genes activated in its embryo. The work appears on the cover of Science.

- Genetic variation: We're more different than we thought
11-22-2006 · EurekAlert!
New research shows that at least 10 percent of genes in the human population can vary in the number of copies of DNA sequences they contain -- a finding that alters current thinking that the DNA of any two humans is 99.9 percent similar in content and identity. This discovery of genetic variation is expected to change the way scientists think about genetic diseases and evolution.

- Bank on a Cure researchers identify pathways mediating myeloma treatment side effects
12-11-2006 · EurekAlert!
Thalidomide is a widely prescribed treatment for multiple myeloma. However, an estimated 15 to 30 percent of patients suffer venous thromboembolisms (VTEs), blood clots, as a major complication. The Bank On A Cure DNA-bank researchers have identified four gene clusters associated with the VTEs. Identifying the associated single nucleotide polymorphisms (SNPs) for use as markers, may lead to the development of screenings and tailored interventions to prevent these side effects, as a major step toward personalized medicine.

- New study sheds light on 'dark states' in DNA
01-09-2007 · EurekAlert!
Chemists at Ohio State University have probed an unusual high-energy state produced in single nucleotides -- the building blocks of DNA and RNA -- when they absorb ultraviolet (UV) light. This is the first time scientists have been able to probe the "dark" energy state -- so called because it cannot be detected by fluorescence techniques used to study other high-energy states created in DNA by UV light.
