The secret lives of whales

...rs in the Deep Sea—A New World Discovered Earlier forensic DNA work by Palumbi and his colleagues revealed that whale populations in the North Atlantic were as much as ten times greater than today. New technologies that allow researchers to observe the deep-sea, now point to another unintended legacy of hunt...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

...ves that one of the first applications could be in forensic science, where time, the traumatic circumstances of a crime scene or the environment has caused DNA samples to become degraded. "We hope this gives criminal investigators another tool to re-open cold cases or revisit crime scenes, stringing together ...

Researchers develop rapid diagnostic tool for pathogen identification

...s such as blood product surveillance, agriculture, forensic microbiology, and biodefense.?/p> To address the need for highly sensitive diagnostics, researchers built on an established method known as polymerase chain reaction that allows amplification of genetic sequences and on a technology previously us...

Microbial forensics: The next great forensic challenge

...is in the process of developing a strong microbial forensic program to attribute and prosecute such attacks, a.... "It is imperative to establish robust microbial forensic capabilities, with the power of the methods, results, and interpretations well understood and defens...

Bioelectronic ‘signatures?hold key to DNA mutations

...eases, detection of infectious agents and reliable forensic analysis. Wang, who recently was recruited to the Biodesign Institute and serves a joint appointment as professor in the chemical and materials department at the Ira A. Fulton School of Engineering and the Department of Chemistry, is a renowned expe...

Aptamer-based Biosensor screens Air Force personnel and equipment

...a bleach solution and then safely transported to a forensic laboratory for further analysis where it can be opened to retrieve the sample material. A liquid crystal display, or LCD, provides a quantitative readout of the concentration of targeted material present, and a set of red, yellow, and green light em...

New tooth enamel dating technique could help identify disaster victims

...uclear testing in the 1950s and 1960s is providing forensic scientists with a more precise way to determine a ...tion of the journal Nature. Buchholz said Swedish forensic scientists already have used enamel dating to help narrow the search for victims of last December's ...

UF study first to quantify validity of DNA I.D. tool using marine snails

...es its benefits to ecology, DNA barcoding has some forensic applications, Meyer said. One applied use already being employed is identifying the bird species responsible when a carcass damages an airplane engine, he said. "Engines are built to withstand strikes by birds up to a certain size, but not a large cr...

Detection of DNA on nanotubes offers new sensing, sequencing technologies

...us biological agents to simpler and more efficient forensic identification. In the Jan. 27 issue of the journal Science, chemical and biomolecular engineering professor Michael Strano and his students reported that single-walled carbon nanotubes coated with DNA could be placed in living cells and detect trac...

Eminent inventor of DNA fingerprinting gains new recognition

...he clone of another sheep. "The new discipline of forensic molecular biology is therefore a direct outcome of Jeffreys' research, but his discoveries have also opened up other doors, for example the ability to determine whether someone is a carrier of certain pathogenic genes. Most recently, Jeffreys has con...

Magnetic computer sensors may help study biomolecules

... simultaneously for massively parallel medical and forensic studies—a sort of magnetic random access memory (MRAM) for biosciences. Spin valves are made by stacking thin layers of materials with different magnetic properties. Their net magnetization can be switched on and off by applying an external magnet...
