Recovering DNA from challenging forensic evidence in forensic genomics
(Press-News.org) New Rochelle, NY, July 19, 2021--Duct tape and items retrieved from the water are common pieces of evidence in forensic cases. A new study evaluates the recovery of DNA from folded duct tape that has been submerged in ocean water for up to 2 weeks. The study is published in the peer-reviewed journal Forensic Genomics. Click here to read the article now.
Joseph Donfack, PhD, from the Federal Bureau of Investigation (FBI) Laboratory Division, and coauthors showed that it is possible to recover enough DNA to yield a complete short tandem repeat (STR) profile from folded duct tape that has been submerged in ocean water for up to 2 weeks if the initial amount of cellular material is sufficient. They concluded that "the durability and adhesive nature of duct tape seem to provide protection to cellular material on its surface while submerged in aqueous environments."
Also published in the current issue of Forensic Genomics is the article entitled "Genes, Race, Ancestry and Identity in Forensic Anthropology: Historical Perspectives and Contemporary Concerns," by Amy Michael, PhD, University of New Hampshire, Jennifer Bengtson, PhD, Southeast Missouri State University, and Samantha Blatt, PhD, Idaho State University. "As anthropologists who collaborate with Forensic Genomics experts, we are interested in considering how debates within anthropological circles might inform--or be informed by--detailed biogeographical ancestry estimates generated as part of forensic genomic analyses," state the authors. "In this article, we summarize the history of the race concept in anthropology and contemporary debates about ancestry estimation occurring more specifically among forensic anthropologists." The proper assessment of biogeographical ancestry can be key for identifying unknown persons from forensic evidence.

On 23 July 2012, humanity escaped technological and economic disaster. A diffuse cloud of magnetized plasma in the shape of a slinky toy tens of thousands of kilometers across was hurled from the Sun at a speed of hundreds of kilometers per second.
This coronal mass ejection (CME) just missed the Earth because its origin on the Sun was facing away from our planet at the time. Had it hit the Earth, satellites might have been disabled, power grids around the globe knocked out, GPS systems, self-driving cars, and electronics jammed, and railway tracks ...
Retail traders often fear that reducing the amount of urban space made available for parking private vehicles would have a negative effect on their businesses. A survey conducted by researchers from the Institute for Advanced Sustainability Studies (IASS) on two shopping streets in Berlin shows that traders have a skewed perception of their customers' mobility habits. The findings of this research will facilitate better-informed decision-making around urban land-use planning.
The researchers surveyed around 2,000 customers and 145 retailers on Kottbusser Damm (Friedrichshain-Kreuzberg district) and Hermannstraße (Neukölln district). The vast majority of shoppers - 93 per cent - had not travelled to their ...
No benefit of high-flow therapy (HFT) can be derived from the available study data for patients with advanced chronic obstructive pulmonary disease (COPD) or chronic type 1 respiratory failure. It therefore remains unclear whether this form of treatment has advantages over long-term oxygen therapy (LTOT) or non-invasive ventilation (NIV).
This is the conclusion of the benefit assessment that the Institute for Quality and Efficiency in Health Care (IQWiG) has now completed. The Federal Joint Committee (G-BA) had commissioned IQWiG to investigate the advantages and disadvantages of HFT in patients with stable, advanced COPD or chronic respiratory failure with oxygen deficiency ...
These motions were measured by analyzing 10 years of observations from NASA's Solar Dynamics Observatory (SDO). Using computer models, the scientists have shown that the newly discovered oscillations are resonant modes and owe their existence to the Sun's differential rotation. The oscillations will help establish novel ways to probe the Sun's interior and obtain information about our star's inner structure and dynamics. The scientists describe their findings in today's issue of the journal Astronomy & Astrophysics.
In the 1960s the Sun'ss high musical notes were discovered: The Sun rings like a bell. ...
New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution - underlining that species can diversify surprisingly quickly under certain conditions.
The zoologists, from Trinity College Dublin's School of Natural Sciences, sequenced DNA and took measurements and song recordings from Sulawesi Babblers (Pellorneum celebense), shy birds that live in the undergrowth on Indonesian islands.
Although these islands were connected by land bridges just tens of thousands of years ago, and although the babblers look ...
One of the leading thinkers in nano-science has called on the energy materials community to help finally put an end to the world's reliance on fossil fuels.
In a hard-hitting editorial published by Energy and Environmental Materials, Professor Ravi Silva, Director of the Advanced Technology Institute (ATI) at the University of Surrey, argues that there are no coherent excuses left to justify the use of fossil fuels. In his paper, Professor Silva challenges the scientific community to lead the world away from a reality where fossil fuels still account for 80 per cent of the energy mix.
While the cost of clean energy generation has plummeted over recent years, ...
Hydropower has massive potential as a source of clean electricity, and the Indus basin can be a key player in fulfilling long-term energy storage demands across Africa, Asia, Europe, and the Middle East. IIASA researchers explored the role the Indus basin could play to support global sustainable development.
According to the International Energy Agency (IEA), the growth of hydropower plants worldwide is set to slow down this decade. This puts at risk the ambitions of countries across the globe aiming to reach net-zero emissions while ensuring reliable and affordable energy supplies for their citizens. Even so, there are thousands of dams planned to be built this next decade. New hydropower dams installed worldwide are forecasted to increase global hydroelectricity ...
Decreasing bacterial acidity could help reduce antimicrobial resistance by eliminating bacteria that can survive being treated with antibiotics.
Scientists at the University of Exeter have developed a novel method, which allows users to measure the pH of individual bacteria before, during and after treatment with antibiotics.
The research, published in the journal mBio, lays the foundation for understanding the special properties of bacteria that survive being treated with antibiotics, so that new ways of targeting them can be developed.
The Exeter University research team found that even before antibiotic treatment, common infection causing Escherichia coli cells that can survive treatment have a more acidic intracellular pH compared to clonal cells that are eliminated ...
Interstellar clouds are the birthplaces of new stars, but they also play an important role in the origins of life in the Universe through regions of dust and gas in which chemical compounds form. The research group, molecular systems, led by ERC prize winner Roland Wester at the Institute for ion physics and applied physics at the University of Innsbruck, has set itself the task of better understanding the development of elementary molecules in space. "Put simply, our ion trap allows us to recreate the conditions in space in our laboratory," explains ...
