Women rate photographs of male faces as more attractive and are more likely to date the men pictured when they have previously heard music. Moreover, highly arousing music led to the largest effect on sexual attraction. A team of psychologists led by Manuela Marin (University of Innsbruck) and Helmut Leder (University of Vienna) explains the significance of this finding in relation to the origins of music in their latest publication in the scientific journal PLOS ONE.

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century.

TU Graz researchers develop new brain-computer interface application which allows music to be composed by the power of thought. How this works is shown in the current issue of the journal PLOS ONE. Brain-computer interfaces, known as BCI, can replace bodily functions to a certain degree. Thanks to BCI, physically impaired persons can control special prostheses through the power of their minds, surf in internet and write emails.

The bending of a hook into wire to fish for the handle of a basket by the crow Betty 15 years ago stunned the scientific world. However, the finding was recently relegated as similar behavioural routines were discovered in the natural repertoire of the same species, suggesting the possibility that Betty's tool manufacture was less intelligent than previously believed.

Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses.

Researchers from ETH Zurich and the University of Vienna have discovered a type of bacteria that uses tiny daggers to prevent itself from being eaten by amoebae. The scientists also resolved the three-dimensional structure of the mechanism that allows the micro-daggers to be shot quickly. Bacteria have to watch out for amoeba.

Flowering plants with at least 300,000 species are by far the most diverse group of plants on Earth. They include almost all the species used by people for food, medicine, and many other purposes. However, flowering plants arose only about 140 million years ago, quite late in the evolution of plants, toward the end of the age of the dinosaurs, but since then have diversified spectacularly.

By Martina Geier The pharma industry is in search of sustainable and cost-effective manufacturing processes for drugs. In the "CHEM21" project, project teams from TU Graz and acib developed genetic tools to provide tailored microorganisms for quick and straight forward drug production approaches. Classical drug production processes often require up to 100 kg of raw materials to manufacture 1 kg of the active ingredient of a drug.

American alligators produce loud, low-frequency vocalizations called "bellows". Cognitive biologists at the University of Vienna, Stephan Reber and Tecumseh Fitch, investigated these vocalizations and found that they reveal the caller's body size. Alligators can use this information to avoid unpromising contests for mates and breeding areas.

A new bioinformatics tool to compare genome data has been developed by teams from the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, together with researchers from Australia and Canada. The program called 'ModelFinder' uses a fast algorithm and allows previously not attainable new insights into evolution.

Acute psychosocial stress leads to increased empathy and prosocial behavior. An international team of researchers led by Claus Lamm from the University of Vienna investigated the effects of stress on neural mechanisms and tested the relationship between empathy and prosocial behavior in a new experiment.

In order for a fuel cell to work, it needs an oxidising agent. TU Wien has now found a way to explain why oxygen does not always enter fuel cells effectively, rendering them unusable. Fuel cells use a simple chemical reaction, such as the combination of oxygen and hydrogen to form water, to generate electricity.

Ravens have impressive cognitive skills when interacting with conspecifics - comparable to many primates, whose social intelligence has been related to their life in groups. An international collaboration of researchers led by Thomas Bugnyar, Professor at the Department of Cognitive Biology, University of Vienna, could uncover for the first time the group dynamics of non-breeding ravens.

Since a couple of decades, metal-containing drugs have been successfully used to fight against certain types of cancer. The lack of knowledge about the underlying molecular mechanisms slows down the search for new and more efficient chemotherapeutic agents. An international team of scientists, led by Leticia González from the University of Vienna and Jacinto Sá from the Uppsala University, have developed a protocol that is able to detect how metal-based drugs interact with DNA.

For the first time ever, researchers at TU Graz and the Medical University of Graz have managed to functionally characterise the three-dimensional interaction between red-light receptors and enzymatic effectors. The results, with implications for optogenetics, have been published in Science Advances.

Neurotransmitter transporters are some of the most popular transport proteins in research as they play a major role in the processing of signals in the brain. A joint study by TU Wien and the Medical University of Vienna has now successfully demonstrated for the first time the structural impact of membrane lipids on medically relevant serotonin transporters.

Chemists are investigating a substance class for biological and pharmaceutical applications Annette Rompel and her team of the Department of Biophysical Chemistry at the University of Vienna are investigating so-called polyoxometalates. These compounds exhibit a great diversity and offer the scientists a wide range of applications.

"Till death do us part" - for marine bristle worms, these words are invariably true: Shortly after mating, the parent worms die, leaving thousands of newly fertilized eggs to develop in the water. This extreme all-or-nothing mode of reproduction demonstrates a general principle: Animals need to decide if they invest their available energy stores either in growth or in reproduction.
