Taking a look at generosity within the crow family reveals parallels with human evolution. Working together to raise offspring and increased tolerance towards group members contribute to the emergence of generous behavior among ravens, crows, magpies and company - similarly as it did for our human ancestors.

Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the earth's history and its development. Additional pictures for download at the end of the text How has the climate changed in the course of the earth's history? Which climatic processes have influenced the earth and its atmosphere? Paleoclimatology seeks answers to such questions in order to better understand climate changes and to derive forecasts for future climate scenarios.

New Deep Learning Models: Fewer Neurons, More Intelligence
Artificial intelligence (AI) can become more efficient and reliable if it is made to mimic biological models. New approaches in AI research are hugely successful in experiments. Artificial intelligence has arrived in our everyday lives-from search engines to self-driving cars. This has to do with the enormous computing power that has become available in recent years.

New findings pave the way to environmentally friendly supercapacitors
Similar to batteries, supercapacitors are suitable for the repeated storage of electrical energy. TU Graz researchers have presented a particularly safe and sustainable variant of such a supercapacitor. Harald Fitzek, Christian Prehal and Qamar Abbas (from left) at the SAXS facility SAXSpoint 2.0 (Anton Paar GmbH): With their work at Graz University of Technology, the researchers are providing new insights into hybrid supercapacitors.

Ecological power storage battery made of vanillin
Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step towards ecologically sustainable energy storage. TU Graz researcher Stefan Spirk has found a way to replace liquid electrolytes in redox flow batteries by vanillin.

Styrian technological innovation: The smallest particle sensor in the world - made in Graz
TU Graz, ams and Silicon Austria Labs has developed a compact and energy-efficient sensor for mobile devices, which informs users in real time about the fine dust content in the air and warns them in case of elevated values. The prototype of the particle sensor (black square in the middle of the board) developed at TU Graz compared in size with a one-cent coin.

Physicists Discover New Magnetoelectric Effect
In a very unusual way, the electrical and magnetic properties of a particular crystal are linked together - the phenomenon was discovered and explained at TU Wien (Vienna). Electricity and magnetism are closely related: Power lines generate a magnetic field, rotating magnets in a generator produce electricity.

Mineral undergoes self-healing of irradiation damage
Mineral undergoes self-healing of irradiation damage
Several minerals suffer radioactive self-irradiation and hence experience long-term changes of their properties. The mineral monazite virtually behaves "just alike Camembert cheese in which holes are drilled": Existing radiation damage heals itself. An international research team led by Lutz Nasdala, Institute of Mineralogy and Crystallography, University of Vienna, conducted an ion-irradiation study that has unravelled the causes of the self-healing of monazite.

Attention, the electron is too fast!
Why do different measurements of material properties sometimes give different results? A research team led by the TU Vienna has now found an important answer. It is very hard to take a photo of a hummingbird flapping its wings 50 times per second. The exposure time has to be much shorter than the characteristic time scale of the wing beat, otherwise you will only see a colorful blur.

Autophagy: the beginning of the end
Autophagy: the beginning of the end
Scientists reveal key steps in the formation of the recycling cen-ters of the cell Autophagy, from the Greek for 'self-eating', is an essential process that isolates and recycles cellular components under conditions of stress or when resources are limited. Cargoes such as misfolded proteins or damaged organelles are captured in a double membrane-bound com-partment called the autophagosome and targeted for degradation.

A team led by Dr. Axel U. J. Lode from the University of Freiburg's Institute of Physics has now described in the journal Physical Review Letters how the use of dipolar atoms enables even the realization and precise measurement of structures that have not yet been observed in any material.
