In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Although it also performs some functions in men, estrogen, the main female sex hormone, is involved in a myriad of processes, ...

DNA origami cages constrain individual proteins toward preferred orientations on electrodes, dramatically improving electrical measurement precision and enabling detection of subtle structural changes ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

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 ...

Before Watson and Crick basked in Nobel glory, before The Double Helix mythologized their genius, there was the photo. Photo 51 — crisp, clear, and groundbreaking — captured by Dr. Rosalind Franklin, ...

Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually ...
