No one has hours to scour the papers to keep up with the latest news, so we’ve curated the top news stories in the field of Forensic Science for this week. Here’s what you need to know to get out the door!
For nearly two decades, forensic scientists at the state’s crime lab have been trying to help police identify the person responsible for a series of rapes that took place between the years 2001 and 2008.
A $1.4 million grant Sasinouski successfully applied for opened up a new avenue to crack the case using forensic genealogy.
Evidence was sent to Bode Technologies to connect the DNA of the suspect to one uploaded to a public database by people tracking their ancestry.
Colorado investigators used DNA and genetic genealogy to solve the rape and murder of a 23-year-old Denver woman five decades ago. Betty Jones was murdered in 1970, and investigators said Thursday that her killer was Paul Martin, a man who died last year.
Researchers at Amsterdam UMC are now able to more accurately home in on the time of death of victims at a crime scene using a newly-developed technique, the hospital center announced on Saturday.
Currently, time of death is recorded with a margin of error of several hours, according to the researchers. Using the new technique, which combines temperature and weight measurements, the margin of error is reduced to under an hour.
The left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs, but unlike righthanded B-DNA, which has major and minor grooves between the twists of its sugar-phosphate backbones, Z-DNA’s grooves show little difference in width. In addition, every other base in a stretch of Z-DNA takes on a different orientation relative to the sugar backbone than the arrangement in B-DNA, giving this alternative form of DNA the zig-zag shape for which it was named.
Different “Canaanite” people from the Bronze Age Southern Levant not only culturally, but also genetically resemble each other more than other populations. A team around Ron Pinhasi from the Department of Evolutionary Anthropology found in a recent study that their DNA is a mixture of two populations: The Chalcolithic Zagros and Early Bronze Age Caucasus.
The Dead Sea Scrolls are like an ancient puzzle that researchers and scholars are trying to piece together, but multiple obstacles block the way. Now, a new study has suggested a potential aid in finding the way these puzzle pieces fit together: animal DNA from the skins used to make the scrolls.
As health care workers for the living are hailed as front line heroes during the COVID-19 crisis, experts working in pathology and forensic sciences are serving in equally critical public health roles during the pandemic. TMC News spoke with Pramod Gumpeni, M.D., assistant deputy chief medical examiner at Harris County Institute of Forensic Sciences (HCIFS), to learn more about “death care” and how the institute is collaborating with hospitals and public health agencies to better understand COVID-19 disease and help curb the spread of the SARS-CoV-2 virus.
