PUBLIC RELEASE DATE: 25-Jun-2014 Contact: Zach Veilleux zveilleux@rockefeller.edu 212-327-8982 Rockefeller University Genomic sequencing is supposed to reveal the entire genetic makeup of an organism. For infectious disease specialists, the technology can be used to analyze a disease-causing bacterium to determine how much harm it is capable of causing and whether or not it will be resistant to antibiotics. But new research at Rockefeller University suggests that current sequencing protocols overlook crucial bits of information: isolated pieces of DNA floating outside the bacterial chromosome, the core of a cell's genetic material. "Extensive sequencing of chromosomal DNA has been performed for a variety of pathogenic organisms, but these sequences fail to uncover the presence of DNA elements in the cell's cytoplasm. As a result, the DNA profile of a pathogenic bacteria may be incomplete," says Vincent Fischetti, head of the Laboratory of Bacterial Pathogenesis and Immunology. "We have now devised a way to identify these elements." Extrachromosomal DNA can include bacteria-infecting viruses, known as phages, and strands of self-replicating DNA, known as plasmids, often picked up from other bacteria. These phages and plasmids can easily move between bacterial cells, and scientists have known for some time that, as a result, these so-called … Continue reading →

AAP A scientist (pic) says Allison Baden-Clay's DNA was found in a car she and her husband owned. How many times? How were hotels paid for? Do you regret the whole thing or just being caught? These were some of the questions running through Brisbane mother Allison Baden-Clay's mind in the days before she disappeared, according to court evidence. Pages from the 43-year-old's diary were shown to the jury in her husband Gerard's murder trial, as it draws to a close. The final diary entry was dated April 18, 2012, just two days before Baden-Clay reported his wife missing. The entry, a long list of crossed-out questions and statements, shows her husband's three-and-a-half-year affair with his former colleague Toni McHugh was playing heavily on her mind. "How many people in the office knew?" was one question. "Were you prepared to live with the guilt if I hadn't found out?" was another. The mother of three also wrote: "Really hurt - had so many opportunities to tell me", and "Let me believe it was all my fault". The diary entry ended with: "Find whole thing dirty - maybe I'm prudent(sic)? Still get sick in stomach". See the article here: Blood matched … Continue reading →

Video will begin in 5 seconds. Gerard Baden-Clay gives a police interview the day after his wife went missing, saying "I just want her to come home". A blood stain found in the boot of Allison Baden-Clays four-wheel-drive matched the Brisbane mothers DNA, a court has been told. Mrs Baden-Clay was reported missing by her husband Gerard on the morning of April 20, 2012. Police found a blood stain in the boot of the familys Holden Captiva three days later. A police photo of Allison Baden-Clay's car. Photo: Supplied The stain was first tested with the chemical luminol, which glows fluorescent blue with the presence of blood. Advertisement The test returned a positive reading for blood. A swab from the blood stain was tested by senior Queensland Health forensic officer Amanda Reeves.

June 25, 2014 Image Caption: Molecular dynamics of DNA origami. The image shows two stages in the temporal evolution of synthetic DNA nanostructures imaged through all-atom molecular dynamics simulations on Stampede. Scientists believe DNA origami will permit easy fabrication of nanoscale objects. Credit: Jejoong Yoo and Aleksei Aksimentiev, Department of Physics, University of Illinois Aaron Dubrow, National Science Foundation Aleksei Aksimentiev, a professor of physics at the University of Illinois-Urbana Champaign, used the National Science Foundation-supported Stampede supercomputer to explore a cutting-edge method of DNA sequencing. The method uses an electric field to drive a strand of DNA through a small hole, or nanopore, either in silicon or a biological membrane. By controlling this process precisely and measuring the change in ionic current as the DNA strands move through the pore of the membrane, the sequencer can read each base pair in order. Stampede is by far the best computer system my group has used over the past 10 years, Aksimentiev said. Being able to routinely obtain 40-80 nanoseconds of molecular dynamic simulations in 24 hours, regardless of the systems size, has been essential for us to make progress with rapidly evolving projects. Aksimentiev and his group showed that localized … Continue reading →
