Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is known as the diffraction limit of light. Super-resolution imaging techniques, ...

In recent years, technologies that allow scientists to study a person's DNA at single-molecule resolution have vastly expanded our knowledge of the human genome, the microbiome, and the genetic basis ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

Thymine modified polymer for delivering DNA into cells. A thymine modified compound, poly (ethylene glycol) (PEG), is bound to DNA through an annealing process, then delivered by intramuscular ...

Roche's AXELIOS 1 enters next generation DNA sequencing. Can it or rivals unseat Illumina's long-standing market dominance?

Polymerase chain reaction (PCR) is a workhorse for quantifying nucleic acids across a range of applications, including biomanufacturing and clinical research for viral titer, vector copy number, ...

Schematic showing a single DNA duplex bridging two gold electrodes (yellow) patterned on a silicon nitride substrate (green). The setup allows measurement of electrical conductance as metal ions bind ...

Researchers have built an artificial protein motor that walks in a set direction along a strand of DNA. It moves one step at ...

Add Yahoo as a preferred source to see more of our stories on Google. A Tokyo team built a neutral PEG-DNA complex that boosted gene expression in mouse muscle, avoiding cation-linked inflammation.

Researchers extracted DNA from long-dead animals that lived in South Africa during the last ice age, revealing that genetic ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...
