How to start a nanomotor?
How to start a nanomotor?
Research news Most people have never heard of them, and yet every living being needs them to survive: fine protrusions of cells known as cilia. They allow sperm to move, form fine protective hairs in the lungs and play a crucial role in the differentiation of organs in embryos. A research team at the Technical University of Munich (TUM) has now reconstructed the protein complex responsible for transport within cilia, which plays a decisive role in their functioning.

Ultracold atoms and ultrafast lasers: Hamburg scientists combine experimental expertise
Ultracold atoms and ultrafast lasers: Hamburg scientists combine experimental expertise
Two separate research fields have been united in Hamburg for the very first time. Ultrashort laser pulses enable us to observe and manipulate matter on very short time scales, whereas ultracold atoms permit experiments with high precision and controllability. In the cluster of excellence "The Hamburg Centre for Ultrafast Imaging," scientists from Universität Hamburg have united the two research fields and succeeded in observing the emergence of ions in ultracold atoms.

New Insights into the Maturation of miRNAs
New Insights into the Maturation of miRNAs
An international research team has used a structural biological approach to elucidate the maturation of a cancer-causing microRNA in gene regulation. In the future, the authors hope to develop new therapies based on their findings. MicroRNAs (miRNAs) are a class of molecules consisting of short RNA sequences that inhibit the formation of certain proteins by destroying the corresponding RNA blueprint.

Give and Take: How We Recognize Interactions
Give and Take: How We Recognize Interactions
Tübingen neuroscientists investigate how actions that relate be-tween individuals are recognised and represented in the brain Social behaviour relies on interactions with others. How does our brain perceive and process these interactions' Until recently, psychologists and neuroscientists have mainly investigated the neuronal processing of individual actions.

Breakthrough in the search for an alternative to chick killing
Research news For economic reasons, around 50 million male chicks die every year in Germany because they do not lay eggs and provide poor meat. Several teams are looking for alternatives to stop the killing of day-old male chicks. Scientists at the Technical University of Munich (TUM) have developed a method for non-invasive fertility and sex determination that was currently patented.

Wave fronts and ant trails
Wave fronts and ant trails
Research news Munich physicists have discovered unique patterning phenomena in systems whose parts move actively. Despite identical initial conditions, two different states can coexist and dynamically interconvert. Their findings provide new insights into the variety of biological processes. Bird flocks and bacterial suspensions, but also the dynamic filamentous protein systems that make up the cytoskeleton of eukaryotic cells, have something in common.

Complex Organic Molecules On Saturn's Moon Enceladus
Complex Organic Molecules On Saturn’s Moon Enceladus
Under its icy crust, Saturn's moon Enceladus conceals an global ocean of liquid water. A detector on the Cassini space probe detected ice particles propelled from Enceladus that contain high concentrations of organic substances. They exhibit the structures typical of highly complex macromolecular compounds.

The attosecond stopwatch
The attosecond stopwatch
Research news Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Quantum Mechanics: Entanglements In Ultracold Atomic Clouds
Quantum Mechanics: Entanglements In Ultracold Atomic Clouds
A system's state is characterised as entangled or quantum correlated if two or more particles cannot be described as a combination of separate, independent states but only as a whole. Researchers at the Kirchhoff Institute for Physics of Heidelberg University recently succeeded in verifying so-called non-local quantum correlations between ultracold clouds of rubidium atoms.

Closing the gap: On the road to terahertz electronics
Research news A team headed by the TUM physicists Alexander Holleitner and Reinhard Kienberger has succeeded for the first time in generating ultrashort electric pulses on a chip using metal antennas only a few nanometers in size, then running the signals a few millimeters above the surface and reading them in again a controlled manner.

The jazz bell
The jazz bell
Research news Researchers at Technical University of Munich (TUM) are using computer simulations to investigate how and why bells ring. The virtual models result in new bell designs that generate highly unusual harmonies - for example a jazzy A9 chord. Now the world's first jazz bell has been cast. The high art of bell casting requires a wealth of experience: In order for the finished bell to create a harmonious sound, the casting mold has to have the exactly right shape, narrow at the top, wide at the bottom, bulges in just the right places.

Polar ice may be softer than we thought
Polar ice may be softer than we thought
Tübingen and international researchers investigate ice flow speed in northern Greenland, correcting models predicting sea level change Ice is a material that can flow like a very viscous liquid. In the polar ice sheets, it flows towards the oceans under its own weight. Knowing how fast the ice flows is of crucial importance to predict future sea level rises, particularly under changing climate conditions.

Producing sensors with an inkjet printer
Research news Microelectrodes can be used for direct measurement of electrical signals in the brain or heart. These applications require soft materials, however. With existing methods, attaching electrodes to such materials poses significant challenges. A team at the Technical University of Munich (TUM) has now succeeded in printing electrodes directly onto several soft substrates.

Pacemakers on a roller test bench - TUM
Research news Pacemakers and defibrillators are often implanted in patients with heart failure or cardiac arrhythmias to regulate heart function. These devices are susceptible to electromagnetic interference, which can potentially occur in electric cars. In a recent study, however, a team led by Dr. Carsten Lennerz, a cardiologist at the German Heart Centre Munich and scientist at the German Centre for Cardiovascular Research (DZHK), concludes that current electric cars pose no threat to patients.
