Trying to untangle a knot in a mess of strings can be frustrating and time-consuming. But not so for molecular ...

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 ...

Scientists study a molecular machine that moves jumping genes in DNA, paving the way for a new gene editing tool beyond CRISPR-Cas9. (Nanowerk News) More than a decade ago, scientists harnessed a ...

Shixin Liu is pioneering new ways of studying the tiny proteins that copy and read DNA in living cells. (Credit: Roshni ...

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 ...

Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria, the ‘powerhouses’ of our cells, allows us to make the fuel we need from sugars, a ...

Tiny machines built from individual molecules are moving from science fiction into working hardware, promising to reshape medicine, manufacturing, and even computing. Instead of gears and pistons, ...

Professor Jiawen Chen and Associate Researcher Yan Wang from South China Normal University, in collaboration with Professor Ben L. Feringa's team at the University of Groningen, Netherlands, designed ...

At the dawn of complex life, evolution created a container for DNA, its most treasured item. A few billion years later, 20th-century microscopists looked at this container — the nucleus — up close and ...
