Researchers capture six new structures of the ribosome in action

St. Jude Children's Research Hospital scientists have used single-molecule fluorescence resonance energy transfer (smFRET) and cryogenic electron microscopy (cryo-EM) to capture six new structures of the ribosome and its ...

How chemists are building molecular assembly lines

Four huge robot arms surround the gleaming metal shell of what will soon be a top-of-the-range automobile. They jerk into life, attaching the bonnet, the wing mirrors, and other panels. It's the kind of precision operation ...

How ribosomes are like Russian dolls

Maturation of the ribosome is a complex operation. Work by an LMU team now shows that the 90S precursor of the small 40S subunit undergoes a "molting" process, during which it progressively discards its outermost components.

Super-resolution microscopy reveals a twist inside of cells

If you want to understand the underlying mechanisms of cellular motility and division, then the centriole is the organelle of interest. Each cell has a pair of centrioles which help to segregate chromosomes during cell division. ...

Breakthrough in molecular machines

Molecules are some of life's most basic building blocks. When they work together in the right way, they become molecular machines that can solve the most amazing tasks. They are essential for all organisms by, for example, ...
