Waking proteins up from deep sleep to study their motions

In order to carry out their functions, proteins need to move. Scientists at EPFL have developed a new technique to study motions in proteins with unprecedented accuracy. The method, which is based on NMR, freezes proteins ...

How water molecules dance to activate proteins

An international team of researchers has shed light on the molecular mechanism behind the importance of water for functional protein dynamics. The scientists have discovered that water's ability to flow on the surface of ...

Mathematicians model fluids at the mesoscale

When it comes to boiling water—or the phenomenon of applying heat to a liquid until it transitions to a gas—is there anything left for today's scientists to study? The surprising answer is, yes, quite a bit. How the bubbles ...

What makes Champagne bubbly?

(Phys.org)—Just in time for the holidays, scientists have unraveled some of the chemistry behind the diffusion of CO2 molecules in a glass of Champagne. Among their findings, they discovered that ethanol is the main molecule ...

Classical enzymatic theory revised by including water motions

Enzymes are macromolecular biological catalysists that lead most of chemical reactions in living organisms. The main focus of enzymology lies on enzymes themselves, whereas the role of water motions in mediating the biological ...

"Funnel" attracts bonding partners to biomolecule

New experimental technologies, such as terahertz absorption spectroscopy, pave the way for studies of the dynamics of water molecules surrounding biomolecules. Using this method, the researchers proved some time ago that ...
