Scientists 'watch' as individual alpha-synuclein proteins change shape
In an Early Edition publication of The Proceedings of the National Academy of Sciences (PNAS) this week, the researchers demonstrate the "alpha-synuclein dance" - the switching back and forth of the protein between a ben ...

Optics get magnetic powers
For decades, scientists have studied a class of materials called ‘multiferroics’ in which static electric and magnetic structures are coupled to each other. This allows capabilities such as controlling ...

Neutron scattering confirms DNA is as stretchy as nylon
(PhysOrg.com) -- Neutron scientists at the Institut Laue-Langevin (ILL, France) have measured how fast sound travels along DNA to determine its ‘stiffness’. These findings help to explain how DNA folds, coils and ...

New 3-D model of RNA 'core domain' of enzyme telomerase may offer clues to cancer, aging
(PhysOrg.com) -- Telomerase is an enzyme that maintains the DNA at the ends of our chromosomes, known as telomeres. In the absence of telomerase activity, every time our cells divide, our telomeres get shorter. ...
