A DNA nano-harvester stays on its track inside tumor cells, measuring cancer aggressiveness by detecting a key microRNA biomarker. (Nanowerk Spotlight) Detecting a cancer-linked microRNA inside a ...
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as ...
Macrophages, the immune system’s front-line scavenger cells, do more than simply digest dead cells. A new study published in Nature Communications shows they actively extract nuclear DNA from dying ...
The immune system depends on molecular alarms that detect danger inside cells. One of these alarms is STING, short for ...
Researchers at the Francis Crick Institute have shown that the "pacemaker" controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...
The Korea Research Institute of Standards and Science has developed an ultrasensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA ...
The use of nucleic acid-based nanostructures as synthetic biological tools to interface with and regulate cell processes remains challenging. A major obstacle lies in nuclear delivery and retention ...
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications, describe how ...
YAHOO.COM - Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The ...
A cell nucleus reconstituted in vitro in Xenopus laevis (African clawed frog) egg extract. Left image shows a fluorescence image where DNA has been stained and right image shows a density map of the ...
A team of researchers led by HHMI Investigator Michael Rosen has captured the most detailed images yet of the molecules in synthetic chromatin condensates — droplet-like structures of compacted DNA.
