According to a theoretical model developed by LMU physicists, in cell protrusions, cargo-transporting motor proteins often get in each other’s way. The upshot is that freely diffusing proteins reach the leading edge faster.

Unlocking the secrets of the Achilles’ heel

Transition from tendon to bone connected by collagen fibers

Walking, running, jumping – every movement of the foot stretches the Achilles’ tendon and the loads can approach ten times the body weight. But the connection between the heel bone and Achilles’ tendon withstands this challenge. Scientists at TU Munich including NIM member Prof. Andreas Bausch has now discovered why.

A new spin on electronics

Our computer technology is based on the transport of electric charge in semiconductors. This technology’s potential will be soon reaching its limits since the components deployed cannot be miniaturized further. NIM scientists and colleagues demonstrate an alternative: using an electron’s spin to transmit information.

Hairpins help each other out

The evolution of cells and organisms is thought to have been preceded by a phase in which informational molecules like DNA could be replicated selectively. New work shows that hairpin structures make particularly effective DNA replicators.
