New forensics technique measures individual DNA shedding to aid criminal investigations
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect's individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes......»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
Experimental archaeology sheds light on skill and technique in Bronze Age spear combat
How can we tell whether and how a prehistoric weapon was used? How can we better understand the dexterity and combat skills involved in Bronze Age spear fighting?.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Comprehensive efforts needed to develop health-promoting learning environments, review finds
Mental ill-health among students in higher education is a growing problem globally. Most efforts implemented to address ill-health involve individual treatment and adjustments to pedagogy. But more can and needs to be done at a structural or environm.....»»
Researchers reveal key mechanism in regulating DNA recombination
Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This process requires a set of recombinases polymerized on single-stranded (ss) DNAs called the nucleoprotein filament to undergo h.....»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
Unique IDs for individual (digital) specimens from natural history museums streamline and future-proof science
The wealth of data hosted in natural history collections can contribute to finding a response to global challenges ranging from climate change to biodiversity loss to pandemics. However, today's practices of working with collected bio- and geodiversi.....»»
"Tough and uncompromising" training capable of transforming social work culture
Described as "tough and uncompromising", Grit Breakthrough Programs uses intensive group workshops and individual coaching to challenge assumptions, attitudes, and expectations, with the aim of helping participants break through self-imposed limitati.....»»
Football can improve well-being of people in UK prisons, and could help stop reoffending
The prison overcrowding crisis in the UK has shown the public what researchers and those working in criminal justice have known for years: prisons are unsafe for those serving time and working there......»»
Manufacturers are lucrative targets for cybercriminals
Hackers and other bad actors believe manufacturers are behind on security measures and more likely to pay a ransom......»»
Scientists Figured Out How to Recycle Plastic by Vaporizing It
A new technique could prevent tons of waste in the future—if it can scale......»»
The Titan Submersible Hearings End With Few Solid Answers. Here’s What Comes Next
The Coast Guard hearings into the OceanGate disaster are done. Next comes the full report—and any potential criminal investigations......»»
23andMe Is Sinking Fast. Can the Company Survive?
The home DNA testing boom is over, and 23andMe is running out of options......»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
Franklin expedition captain who died in 1848 was cannibalized by survivors
Scientists matched DNA of living descendent to Capt. James Fitzjames of the HMS Erebus. Scientists at the University of Waterloo have identified one of the doomed crew members of.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Ex-VW Winterkorn"s diesel scam trial suspended due to ailing health
The criminal charges against Winterkorn include fraud, market manipulation and unlawful false testimony before a parliamentary committee......»»
Use Windows event logs for ransomware investigations, JPCERT/CC advises
The JPCERT Coordination Center – the first Computer Security Incident Response Team established in Japan – has compiled a list of entries in Windows event logs that could help enterprise defenders respond to human-operated ransomware atta.....»»
