Computer simulations reveal the energy landscape of ion channels

Every cell of our body is separated from its environment by a lipid bilayer. In order to maintain their biological function and to transduce signals, special proteins, so called ion channels, are embedded in the membrane. ...

Surfaces help quantum switches

The quantum dynamics of hydrogen are central to many problems in nature, being strongly influenced by the environment in which a reaction takes place. In their contribution to PRL, members of the Lise Meitner Group at the ...

Light-activated reversal of anesthesia

In a new study, a light-sensitive moiety has been added to propofol, a commonly used anesthetic, allowing its narcotic effect to be controlled by light. The compound also offers a possible route to the treatment of certain ...

The first stage of the cascade

G proteins are molecular switches on the insides of cell membranes. They convey important signals to the inner workings of the cells. The associated receptors are targeted by all kinds of medications. Scientists at the Technical ...

How medicine literally gets under your skin

If drugs are to enter the body painlessly and efficiently, they can be administered via skin patches. Researchers at Empa and the University of Fribourg are currently developing nano-containers for therapeutic agents that ...
