Chatting coordinates heterogeneity

Bacterial populations can, under certain conditions, react in a coordinated manner to chemical messages produced by a minority of their members, as a new theoretical study carried out by NIM biophysicists from LMU Munich shows.

Supramolecular materials with a time switch

Materials that assemble themselves and then simply disappear at the end of their lifetime are quite common in nature. NIM scientists and colleagues have now successfully developed supramolecular materials that disintegrate at a predetermined time – a feature that could be used in numerous applications.

Saving energy with a tiny spot of silver

In the future, computers are expected to run on light particles instead of electrons. To that end, researchers are testing the use of gold nanoparticle chains as light conductors. LMU scientists now demonstrate how a tiny spot of silver could save enormous amounts of energy in light computation.

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.

Shaken, but not stirred

A team of researchers led by NIM physics professor Immanuel Bloch has experimentally realized an exotic quantum system which is robust to mixing by periodic forces.

What holds the heart together

Our hearts beat a life long. With every beat our heart muscle contracts and expands. How this can work throughout an entire life remains largely a mystery. NIM scientists from TU Munich and a team from Vienna have now measured the forces acting between the building blocks titin and α-actinin which stabilize the muscle.

Lighting up ultrathin films

Based on a study of the optical properties of novel ultrathin semiconductors, NIM researchers have developed a method for rapid and efficient characterization of these materials.

A novel carbon nitride-based polymer is capable of storing electrons energized by sunlight for hours and releasing them on demand. The system might provide the basis for the storage of solar energy in the future.

Ernst Haage Prize for Aliaksandr Bandarenka

NIM member Prof. Aliaksandr Bandarenka (TU Munich) was awarded the Ernst Haage Prize 2016. The prize is given jointly by the Ernst Haage foundation and the Max Planck Institute for Chemical Energy Conversion and endowed with 7.500 EUR. It honors young scientists for outstanding achievements in this research field.

Shaping up to make the cut

Before RNA copies of genes can program the synthesis of proteins, the non-coding regions are removed by the spliceosome. Munich researchers report that distinct conformations of a member of this molecular complex play a vital role in the process.

Genes on the rack

Physicists at LMU have developed a novel nanotool that provides a facile means of characterizing the mechanical properties of biomolecules. They constructed a molecular clamp out of artificial DNA strands that can be programmed to exert a defined force on a test molecule.

Tiny measuring device for humidity and solvent vapors

NIM scientists developed a measuring device which is only a few nanometers in size but fulfills two functions: it detects very low humidity levels and identifies vapors of organic solvents. The central part of the device is a stack of nanolayers.

Measuring forces in the DNA molecule

DNA normally has the structure of a double helix. Among other things, it is stabilized by stacking forces between base pairs. Scientists at the TUM have succeeded at measuring these forces for the very first time on the level of single base pairs. This new knowledge could help to construct precise molecular machines out of DNA.

Random walk into captivity

The cell’s internal skeleton undergoes constant restructuring. LMU physicists now show that its constituent proteins can be efficiently transported to their sites of action by diffusion – provided they can be arrested when they get there.

DNA dominos on a chip

Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. An international team of physicists has now succeeded in artificially recreating this "DNA condensation" on a biochip.

NIM scientists and their colleagues have found a clever way to decouple organic nanosheets grown on metal surfaces. By intercalation of iodine atoms the “organic carpet” behaved almost as it was free-standing: Ideal conditions to transfer organic nanostructures from metal onto more suitable substrates for molecular electronics.

Live is motion

Any system in thermodynamic equilibrium is known to satisfy perfectly balanced forward and backward transitions between any two states. Living systems like cilia violate this principle. Thus, even stochastic fluctuations in such systems could be used to drive a small-scale engine. Picture: C. Hohmann (NIM), M. Leunissen (Dutch Data Design)

The LMU physicist Chase Broedersz and co-workers have developed a way to distinguish the random motions of particles in non-living molecular systems from the motility of active living matter.

The method affords new insights into fundamental biological processes.

Friedrich Simmel receives ERC grant

The NIM member Friedrich Simmel from the Physics Department of TUM won out in the latest round of ERC grants. His interdisciplinary project is at the interface of physics and biology.
