Portable Kit Can Recover Traces of Chemical Evidence
A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris.
Forensics Professor Detects Blood on Revolutionary War Projectiles
More than 230 years after the Revolutionary War ended, Edinboro University professor of forensic science Dr. Ted Yeshion has found the presence of blood on buckshot recovered from a battlefield in upstate New York.
Single Molecule Detection of Contaminants, Explosives or Diseases
A technique that combines the ultrasensitivity of surface-enhanced Raman scattering (SERS) with a slippery surface invented by Penn State researchers will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
Potential New Tool for Forensic Science
Microbial communities associated with humans tick in predictable, clock-like succession following death.
Perfecting Age Estimations Under 25
The Idaho State University Department of Anthropology has received a $510,409 grant from the National Institute of Justice to develop forensic science techniques to better identify individuals under 25 years of age for criminal justice purposes.
Identifying Gender from a Fingerprint
Culprits beware, a University at Albany research group, led by assistant chemistry professor Jan Halámek, is taking crime scene fingerprint identification to a new level.
Viruses, Too, Are Our Fingerprint
A group of researchers from the University of Helsinki and the University of Edinburgh have been the first to find the genetic material of a human virus from old human bones.
Questioning the Validity of Forensic DNA Match Statistic
Fifteen years of criminal cases with affected mixture evidence.
Study Raises Questions About DNA Evidence
University of Indianapolis researchers say contamination through secondary transfer of material could implicate the innocent or help the guilty go free.
'Forensic Toolkit’ to Improve Evidence Detection and Analysis
Students from The University of Dundee have been developing a forensic `toolkit’ that will allow investigators to determine the age of fingerprints, detect traces of steel on bone from stabbings, and produce a biosensitive spray that can reveal traces of bodily fluids at crime scenes.

A Novel Method for the Extraction of Mitochondrial DNA from Human Hair, Skin, and Blood Stain

Pressure Biosciences Inc.

Forensic samples are often limited in their quantity; in addition, the quality of their biomolecules may also be in relatively poor condition. If there is insufficient material for nuclear DNA analysis, mitochondrial DNA (mtDNA) can provide great sensitivity and valuable information from samples such as hair, skin, or blood stains, by taking advantage of the fact that cells may contain thousands of copies mtDNA, while somatic cells typically contain two copies of nuclear DNA. In an effort to increase the safety, speed, simplicity, and efficiency of mtDNA extraction from forensic specimens, Pressure BioSciences, Inc. (PBI) has developed a novel extraction system based on a new, patented process called Pressure Cycling Technology (PCT). This PCT Sample Preparation System (PCT SPS) eliminates the requirement for the use of harsh chemicals and time consuming processes to extract and purify mtDNA from a number of samples. Furthermore, mtDNA may be released from the specimen in the single-use container in which the sample was collected, transported, and stored (PULSE Tube). In addition, mtDNA released by PCT from hair, skin, or blood can be amplified directly by PCR without the need for additional purification. Consequently, the PCT SPS offers a safer, more rapid, simpler, and more efficient method for extracting mtDNA.
