New molecule halts mitochondrial DNA loss before it triggers inflammation. When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration and ...

Epigenetic modifications such as DNA methylation play a key role in regulating gene expression. Emerging evidence suggests that intermediates generated during DNA demethylation may have distinct ...

A team of researchers have developed an easy-to-use colorimetric assay for the detection of food contaminated with salmonella. The assay is based on a novel nucleic acid probe that is cleaved by an ...

We report on single-molecule nanopore sensing combined with position-encoded DNA molecular probes, with chemistry tuned to simultaneously identify various antigen proteins and multiple RNA gene ...

Multiplexed imaging of cell and tissue samples with methods such as fluorescence in situ hybridization (FISH) for nucleic acid targets and immunofluorescence (IF) for protein targets can reveal ...

A shark DNA investigation has revealed the presence of shark species threatened with extinction in products commonly sold in Thailand’s markets. The study identified products derived from 15 shark ...

PCR/qPCR solution will support surveillance and monitoring of the current H5N1 strain of bird flu in response to multi-state outbreak in U.S. dairy cows CORALVILLE, Iowa--(BUSINESS WIRE)--Amidst ...

Light accelerates DNA hybridization using gold nanoparticles and polystyrene microparticles as probes for PCR-free DNA detection. News organizations may use or redistribute this image, with proper ...

Scientists are uncovering the secrets of a fast-acting molecular messaging network that strongly influences how people and all organisms adjust and react to the world around them. While DNA and the ...
