On Monday, a paper announcing that all four DNA bases had been found on an asteroid sparked a lot of headlines. But many of ...

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 ...

Scientists are exploring DNA-based robots, tiny molecular machines that could one day navigate the body, deliver targeted therapies, and even build nanoscale technologies.

DNA, long known as the molecule that carries genetic information, is taking on a new role in science. Researchers now see it ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

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 ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...

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 ...

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 ...
