Scientific instruments of Rosetta's Philae lander

When traveling to far off lands, one packs carefully. What you carry must be comprehensive but not so much that it is a burden. And once you arrive, you must be prepared to do something extraordinary to make the long journey ...

Smallest, fastest-known RNA switches provide new drug targets

(Phys.org)—A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting ...

Virus uses 'Swiss Army knife' protein to cause infection

In an advance in understanding Mother Nature's copy machines, motors, assembly lines and other biological nano-machines, scientists are describing how a multipurpose protein on the tail of a virus bores into bacteria like ...

Reversible method of tagging proteins developed

Chemists at UC San Diego have developed a method that for the first time provides scientists the ability to attach chemical probes onto proteins and subsequently remove them in a repeatable cycle.

Building a biofuel-boosting Swiss Army knife

Researchers at Michigan State University have built a molecular Swiss Army knife that streamlines the molecular machinery of cyanobacteria, also known as blue-green algae, making biofuels and other green chemical production ...

A delivery platform for gene-editing technology

A new delivery system for introducing gene-editing technology into cells could help safely and efficiently correct disease-causing mutations in patients. The system, developed by KAUST scientists, is the first to use sponge-like ...
