A team led by UC Davis researchers have come up with a new way to estimate the biological sex of human skeletal remains based on protein traces from teeth.

That was the case in a murder trial that Bruce McCord, a forensic chemist at Florida International University, served as an expert witness in. A woman was murdered shortly after she went through a divorce, and DNA from her ex-husband was found on her body. But it was hard to tell if the DNA was the result of innocent contact between the two, or if it was incriminating, and came from blood.
New Study: DNA Molecular Tagging is an Effective Tool to Authenticate Denim, One of the Toughest Fabrics
STONY BROOK, N.Y.–(BUSINESS WIRE)–Results of a new study published in the September/October 2018 issue of the AATCC Review confirmed that DNA molecular tagging is an effective tool to authenticate denim and maintains its integrity even after exposed to the rigors of bleaching and abrasion.
CAMDEN, N.J. -Crime scenes might yield DNA evidence to help reveal the identity of a criminal, but law enforcement investigators often are stymied in that determination because genetic material collected can come from more than one person.
A Rutgers University–Camden researcher is working to create new scientific approaches to forensics that may provide new crime-solving tools for law enforcement agencies.
Criminals who naturally shed more DNA than others could be linked to a crime scene with greater accuracy, following the advent of a new DNA test developed by Australian researchers.
The test, which involves the use of a binding dye, allows investigators to determine where DNA evidence has been left behind at a crime scene, potentially cutting the cost of expensive forensic laboratory testing and dramatically reducing the time it takes to identify a DNA profile.
URBANA — A commercial genetic genealogy company that relies on science and public records, combined with old-fashioned detective work, led to the arrest Tuesday of a Mahomet man for one of the most horrendous Champaign County murders in modern history.
Television writers portray DNA evidence as a slam dunk, sealing the fate of many a villain in a fast-paced game of cat and mouse. The reality, however, is that a single DNA sample requires days to analyze, and many samples never get processed at all. DNA profiling has come a long way since its debut in 1986, but in many ways, it’s still in its infancy. Here are four ways researchers are breaking new ground with forensic uses of genetic analysis.
The backlog of sexual assault kit samples in crime laboratories across the nation is a topic that hit the spotlight when a group of journalists uncovered the issue in an open records search of crime lab records in 2015. Reasons for the backlog include lack of staff, lack of funding, and simply, lack of time or a decision not to prosecute the case. Processing samples can be a labor-intensive process.
“If you’re working criminal cases, you need to be able to generate match statistics,” said Katherine Gettings, the NIST biologist who led the study. “The data we’ve published will make it possible for labs that use NGS to generate those statistics.”
FORT WASHINGTON, Pa.–(BUSINESS WIRE)–Nutrisystem, Inc. (Nasdaq: NTRI), a leading provider of health and wellness and weight management products and services including Nutrisystem® and South Beach Diet® brands, today announced the launch of DNA Body Blueprint™, a genetic-based product using a proprietary algorithm that provides an integrated personal action plan focused on eating behaviors, nutrition and metabolism. The national marketing campaign will debut this week.
HARRISBURG, Pa. (WHTM) – More than 25 years after Lancaster County elementary teacher Christy Mirack was brutally killed, an arrest has been made using DNA evidence and a genealogy site.
The same technology led to an arrest in a 30-year-old double murder case in Seattle and also helped police identify a suspect in the Golden State Killer cases.
Fingerprints hold a lot more information than you might realise. They don’t just provide a pattern with which to identify people. They can also contain DNA. And as neither DNA nor fingerprints are infallible ways of working out who was at a location, combining both pieces of evidence could be vital for investigators.
Modern forensics lead Brazos County authorities to executed murderer as likely killer of Virginia Freeman
“The solving of this cold case, after 37 years of investigating, brings relief and closure for the Freeman family, Virginia’s friends, the local real estate industry and our community,” Kirk said Monday.
A technique called Raman spectroscopy provides information about the chemical composition and molecular structure of material. Thus, Igor Lednev and colleagues wanted to see whether they could use this method to analyze blood components to determine the ages of victims and suspects.
AUSTIN — A judge has tossed out some DNA evidence that prosecutors planned to present at the trial for the man charged with with killing a University of Texas student on campus in 2016, KVUE’s news partners at the Austin American-Statesman report.
Meechaiel Criner appeared in court Monday and Tuesday where a discussion regarding the DNA collection software used during the investigation unfolded.
