"Photo 51" was a cleaner version of an earlier X-ray image, "Photo 49," that Rosalind Franklin had already used to calculate ...

A new analysis suggests that Rosalind Franklin, who took the first images of DNA’s double-helix structure, knew far more ...

(Agnes Noy/Catley et al., Nucleic Acids Research, 2026) If you could peer inside a cell's nucleus, you would find DNA tightly ...

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, ...

Metal ions bridging the grooves of two DNA helices explain how they lock together, the first direct look at the DNA zipper proposed in 2001.

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 ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

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 ...

Using advanced imaging techniques and precise microfluidics control to stretch out curly DNA into a straight line, new research demonstrates techniques for stretching and immobilizing DNA with minimum ...
