Biologists take snapshot of fleeting protein process

Structural biologists from Rice University and Baylor College of Medicine (BCM) have captured the first three-dimensional crystalline snapshot of a critical but fleeting process that takes place thousands of times per second ...

Building electronics from the ground up

(Phys.org)—There's hardly a moment in modern life that doesn't involve electronic devices, whether they're guiding you to a destination by GPS or deciding which incoming messages merit a beep, ring or vibration. But our ...

Energy-saving chaperon Hsp90

A special group of proteins, the so-called chaperons, helps other proteins to obtain their correct conformation. Until now scientists supposed that hydrolyzing ATP provides the energy for the large conformational changes ...

Microspiders: Polymerization reaction drives micromotors

(PhysOrg.com) -- Though it seems like science fiction, microscopic "factories" in which nanomachines produce tiny structures for miniaturized components or nanorobots that destroy tumor cells within the body and scrape blockages ...

Life's origins in need of metals

Scientists have proposed a new potential catalyst for jump-starting metabolism, and life itself, on the early Earth. Transition metals like iron, copper and nickel along with small organic molecules could have catalyzed the ...
