New Deep Learning Models: Fewer Neurons, More Intelligence
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.

Cyanobacteria as 'green' catalysts in biotechnology
Cyanobacteria as ’green’ catalysts in biotechnology
By Susanne Eigner Researchers from TU Graz and Ruhr University Bochum show in the journal ACS Catalysis how the catalytic activity of cyanobacteria, also known as blue-green algae, can be significantly increased. This brings biotechnological and thus eco-friendly application a big step closer. Cyanobacteria, despite staining water green through their special pigments, are colloquially known as "blue-green algae", and convert light energy into chemical energy particularly effectively thanks to their highly active photosynthetic cells.

Styrian technological innovation: The smallest particle sensor in the world - made in Graz
By Christoph Pelzl 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. Additional at the end of the text It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices.

Gravity causes homogeneity of the universe
Gravity causes homogeneity of the universe
"During its expansion, the universe evolved towards its present state, which is homogeneous and isotropic on large scales. This is inferred, among other things, from the measurement of the so-called background radiation as nicely seen in the full sky image of the WMAP data.

Physicists Discover New Magnetoelectric Effect
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.

Producing leather-like materials from fungi
Biofabrication includes upcycling of low-cost agricultural and forestry by-products Leather is used as a durable and flexible material in many aspects of everyday life including furniture and clothing. Leather substitutes derived from fungi are considered to be an ethical and environmentally friendly alternative to traditional bovine leather.

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.

The Art of Making Tiny Holes
The Art of Making Tiny Holes
How can you perforate an atomic layer of material and leave the one underneath intact? Scientists at TU Wien (Vienna) developed a technique for processing surfaces on an atomic scale. Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact.
