Electronic zippers control DNA strands

A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry.

Nanotechnology-enhanced DNA analysis

European researchers enhanced the selectivity of state-of-the-art genetic sequencing methods using nanotechnology. Immediate application in detection of strains of Salmonella and Staphylococcus should facilitate speedy identification ...

Aging human bodies and aging human oocytes run on different clocks

Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span, according to Coleen Murphy, ...

Faster DNA analysis at room temperature

DNA microarrays are one of the most powerful tools in molecular biology today. The devices, which can be used to probe biological samples and detect particular genes or genetic sequences, are employed in everything from forensic ...

Technique Detects More Than 700 Antimicrobial-Resistance Genes

(PhysOrg.com) -- Using an advanced genetic screening technique, Agricultural Research Service (ARS) scientists and cooperators have detected, for the first time, more than 700 genes that give microbes like Salmonella and ...
