Fast forensic test can match suspects' DNA with crime samples in 4 hours (8/6/2010)

A newly developed test could make checking DNA from people arrested for crimes with DNA samples from crime scenes stored in forensic databases almost as easy as matching fingerprints. With the test, police could check on whether a person's DNA matches that found at past crime scenes while suspects are still being processed and before a decision on whether to release them on bail. A report on the fast forensic test appears in the ACS' Analytical Chemistry, a semimonthly journal. ...> Full Article

New method manipulates particles for sensors, crime scene testing (6/9/2010)

Researchers at Purdue University have developed a potential new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics. The technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses and DNA, which are contained inside the drops. ...> Full Article

New hand bacteria study holds promise for forensics identification (3/16/2010)

Forensic scientists may soon have a valuable new item in their toolkits -- a way to identify individuals using unique, telltale types of hand bacteria left behind on objects like keyboards and computer mice, says a new University of Colorado at Boulder study. ...> Full Article

Use of DNA evidence is not an open and shut case (2/23/2010)

Whether used to clinch a guilty verdict or predict the end of a CSI episode, DNA evidence has given millions of people a sense of certainty -- but the outcomes of using DNA evidence have often been far from certain, according to David Kaye, Distinguished Professor of Law at Penn State. In his new book, "The Double Helix and the Law of Evidence" (Harvard University Press), Kaye focuses on the intersection of science and law, and emphasizes that DNA evidence is merely information. ...> Full Article

Forensics firm builds on genomic discovery to advance DNA-based identification (10/14/2009)

High-tech forensics firm, Casework Genetics, is applying new technology to forensic evidence enabling law enforcement labs to solve crimes with greater molecular precision and efficiency than ever before. ...> Full Article

A better test to detect DNA for diagnosing disease, investigating crimes (8/28/2009)

Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA. Such tests are done for criminal investigation, disease diagnosis, and other purposes. The new lab-on-a-chip test could lead to wider, more convenient use of DNA testing, the researchers say. Their study is scheduled for the Sept. 2 issue of the Journal of the American Chemical Society, a weekly publication. ...> Full Article

Scientists find new way to extract diluted and contaminated DNA (8/11/2009)

University of British Columbia researchers have developed a new way to extract DNA and RNA from small or heavily contaminated samples that could help forensic investigators and molecular biologists get to "the truth." ...> Full Article

Faster, more cost-effective DNA test for crime scenes, disease diagnosis (7/12/2009)

Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction, a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR in medicine, the criminal justice system and elsewhere, the researchers say. Their study is scheduled for the July 15 issue of Analytical Chemistry, a semi-monthly journal. ...> Full Article
