DNA adds new chapter to Indonesia’s layered human history
A new study from the University of Adelaide and The Australian National University (ANU) has outlined the first genomic evidence of early migration from New Guinea into the Wallacea, an…
Scientists discover a ‘Goldilocks’ zone for DNA organization, opening new doors for drug development
In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known…
DNA of 1,000 year-old maize sheds light on origins of globally important food crop
Researchers have tested ancient DNA from corn found at archaeological sites in Arkansas, shedding new light on the dispersal of one of the world’s most important food crops. By reconstructing…
Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry
A tiny, four-fingered “hand” folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles…
How cells recognize and repair DNA damage
Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic…
Technique to study how proteins bind to DNA is easily misused; New study offers solution
Researchers at University of California San Diego have published new guidelines that could help scientists significantly improve their results when quantifying the interactions between DNA and proteins. Understanding these interactions…
Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers…
Hidden DNA mechanisms of rare genetic diseases uncovered
Researchers at the Pacific Northwest Research Institute (PNRI) and collaborating institutions have made a groundbreaking discovery that could significantly advance our understanding of genomic disorders. Their latest study, funded by…
Cellular activity hints that recycling is in our DNA
Although you may not appreciate them, or have even heard of them, throughout your body, countless microscopic machines called spliceosomes are hard at work. As you sit and read, they…
First step to untangle DNA: Supercoiled DNA captures gyrase like a lasso ropes cattle
Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the…
