Rules devised for building ideal protein molecules from scratch

(Phys.org)—By following certain rules, scientists can prepare architectural plans for building ideal protein molecules not found in the real world. Based on these computer renditions, previously non-existent proteins can ...

Protein knots gain new evolutionary significance

(Phys.org) -- A new study suggests that protein knots, a structure whose formation remains a mystery, may have specific functional advantages that depend on the nature of the protein's architecture.

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 ...

Evolution provides clue to blood clotting

A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting ...

Pull-chain 'polymer' solves puzzle of complex molecular packing

(PhysOrg.com) -- Sometimes the simplest things hold the key to understanding complex effects. It turns out that a humble metal pull-chain -- just like those used on ceiling fans -- can be a pretty good model for complex properties ...

Strain-induced isomerization of molecular chains

National University of Singapore scientists have demonstrated a strain-induced structural rearrangement of one-dimensional (1D) metal-organic molecular chains for potential use in fabricating functional nanostructures.
