More than a decade ago, scientists harnessed a bacterial molecular machine that identifies and cuts specific sections of DNA, revolutionizing the ability to edit genes and accelerating research into t ...

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 ...

Today's science tells us that our bodies are filled with molecular machinery that orchestrates all sorts of life processes. When we think, microscopic "channels" open and close in our brain cell ...

When a woman becomes pregnant, the outcome of that pregnancy depends on many things—including a crucial event that happened ...

Human genes that encode proteins often contain non-coding segments known as introns. Removing introns is crucial for the proper expression of genetic information. Understanding how our cells ...

Biology is full of molecular machines, such as motor proteins and ATP synthase, that operate self-sufficiently through cycles of oxidation and reduction. A team of human chemists at the University of ...

The flux of protons from respiratory supercomplexes (blue) to ATP producing complexes (pink) powers the regeneration of ATP in mitochondria. Mitochondria are the powerhouses in our cells, producing ...

Cell division is one of the most thoroughly studied processes in biology, yet many of its details remain mysterious. A ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

A study published in Nature Communications describes how lymphatic endothelial cells assist in generating robust immune ...

This conceptual version of the catenane made by Michael Kathan and coworkers shows the molecular motor portion of the molecule on the left. Credit: Tommy Wachsmuth/C&EN The molecular machine was ...
