Researchers improve understanding of molecular mechanisms underlying stomach’s acid pump

Nagoya University researchers and colleagues have improved understanding of the molecular mechanisms of a key protein that makes the stomach acidic. Their findings, published in the journal Nature Communications, could lead to better drugs for stomach ulcers and shed light on the functions of similar proteins across the human body.

Supercoiling and looping can transmit mechanical stress along the DNA backbone, shows study

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are known to influence every aspect of DNA activity, but how this happens has not been clear.

Novel method improves the resolution of hard X-ray nanotomography

It's been a truth for a long time: if you want to study the movement and behavior of single atoms, electron microscopy can give you what X-rays can't. X-rays are good at penetrating into samples -; they allow you to see what happens inside batteries as they charge and discharge, for example -; but historically they have not been able to spatially image with the same precision electrons can.
