Since the discovery, the FSS, which is used by police nationally, has re-examined hundreds of samples and identified the DNA of suspects in 15 serious crimes, including rape, murder and assaults.
A cellulase producing strain was newly isolated from soil samples and identified as Paenibacillus sp. LLZ1.
RT-PCR/ESI-MS detected 74/95 (77.9%) known positive samples and identified an additional 13/185 (7%) from culture-negative samples.
This provides a rapid screening technique to identify heterogeneous samples, classify new samples, and identify misclassified meteorites or interlopers in strewn fields.
FA was performed on the normalized data sets separately, to compare the compositional pattern between analyzed water samples and identify the factors influencing each one.
They extracted DNA sequences from leaf and bark samples and identified which adults had borne the seeds which gave rise to the younger trees.
They partially dissolved samples and identified diamonds by measuring their distinctive atom-to-atom distance under high-resolution transmission electron microscopy.
Now, scientists with the U.S. Fish and Wildlife Service Forensics Laboratory have discovered they can use a mass spectrometer to "sniff" the compounds in wood samples and identify them by their unique, chemical signatures.
