Wandering celestial bodies provide a glimpse into the formation of stars and planets
With observations of one of the closest star-forming regions to the sun a team of international astronomers discovered the largest population of free-floating planets. These celestial bodies do not revolve around a star and are very hard to find due to their very low brightness. The large number of planets now detected provides information about the formation process of stars and planets and important information for future research.

Covid-19 Infections in Nursing Homes: Simulation model for optimal prevention and vaccination strategies
Researchers from TU Graz and Complexity Science Hub (CSH) Vienna have developed a detailed epidemiological model for the spread of the coronavirus in nursing homes. This enables optimal prevention strategies to be identified, as practical experience in Caritas nursing homes has shown. Since the beginning of the coronavirus pandemic, residents of nursing homes have been particularly at risk.

World’s oldest family tree provides new insights into kinship and burial practices in Neolithic times
By analyzing ancient DNA an international team of scientists with participation of Ron Pinhasi's team of the University of Vienna was able to retrace the world's oldest family tree. They took samples from a Neolithic tomb in Britain. In their study published they reveal undiscovered information about the structure of prehistoric families.

New State of Matter: Crystalline and Flowing at the Same Time
Through their research efforts, the team was able to finally disprove an intuitive assumption that in order for two particles of matter to merge and form larger units (i.e. aggregates or clusters), they must be attracted to each other. As early as the turn of the century, a team of soft matter physicists headed by Christos Likos of the University of Vienna predicted on the basis of theoretical considerations that this does not necessarily have to be the case.

The role of bitter receptors in cancer
Bitter taste receptors do not only support humans in tasting. They are also found on cancer cells. A team led by Veronika Somoza from the Faculty of Chemistry at the University of Vienna and the German Leibniz Institute for Food Systems Biology at the Technical University of Munich has investigated the role they play there.

In quantum mechanics, not even time flows as you might expect it to
The boundary between forward and backward blurs in quantum mechanics A team of physicists at the Universities of Vienna, Bristol, the Balearic Islands and the Institute for Quantum Optics and Quantum Information (IQOQI-Vienna) has shown how quantum systems can simultaneously evolve along two opposite time arrows (forward and backward in time).

The Study of the Microbiome Enables New Strategies for Healthy and Climate-Resilient Crops
By Christoph Pelzl Study led by TU Graz shows that apple trees inherit their microbiome to the same extent as their genes. The results lay the foundation for new breeding strategies for healthy and climate-robust fruit and vegetables. Agriculture is facing enormous challenges worldwide due to global changes caused by human activities.

’Coronavirus-proof’ Interiors: New Measuring Method Documents Movements of Infectious Aerosols
By Christoph Pelzl With the method co-developed by TU Graz, virus movements in indoor spaces can be simulated easily and cost-effectively. The method helps to implement measures in rooms that significantly reduce the risk of transmission via the air. Further can be found at the end of the text How far apart must people sit from each other to prevent transmission of the coronavirus via the air?

How to decode the meaning of melodies in animal vocalizations
Evolution led to similarities in the melodies of animal vocalizations and human languages When listening closely, the melodies of human languages and animal vocalizations are very similar. However, it is not yet fully resolved if similar patterns in languages and animal vocalizations also have similar meanings.

Autonomous Driving: Styrian Development Saves Millions in Test Kilometres
By Christoph Pelzl TU Graz, JOANNEUM RESEARCH, AVL and Fraunhofer Austria have developed a method to validate test drives through highly realistic driving simulation studies and to substantially simplify the approval process for automated driving systems. Further images for download at the end of the text Driving simulator tests are popular - for understandable reasons: any scenario can be simulated at the touch of a button.

Profound ecological change in the Eastern Mediterranean Sea
Distinct ecological niches: Tropical species profoundly alter ecosystem functioning in the Eastern Mediterranean Sea - with unknown consequences. Assemblages of tropical non-indigenous species in the Eastern Mediterranean have biological traits that markedly differ from those of native biological communities.

Why do humans possess a twisted birth canal?
Extraordinary shape makes births more difficult, but guarantees stability The relatively narrow human birth canal presumably evolved as a "compromise" between its abilities for parturition, support of the inner organs, and upright walking. But not only the size of the birth canal, also its complex, "twisted" shape is an evolutionary puzzle.

Fighting viruses with interchangeable defense genes
Bacteria rapidly modify mobile parts of their genome to develop resistance to viruses Bacterial viruses, so-called phages, destroy bacteria. Bacteria are constantly exposed to viral attacks. A research team led by Martin Polz, a microbiologist at the University of Vienna, has now studied how bacteria defend themselves against viral predators.

Let there be Light: Photoinitiators for Dental Fillings, Contact Lenses and Dentures etc
By Susanne Filzwieser Photoinitiators ensure that liquid plastic - for example for dental fillings - hardens quickly by means of light. Thanks to a new synthesis method developed by TU Graz, these initiators can be produced cheaply, something which will open up further doors for the technology. Anyone who has ever been in the dentist's chair with a hole in their tooth is probably familiar with the procedure.

Fire Tests Show that Austria’s Tunnels are Fit for Electric Cars
By Susanne Filzwieser TU Graz, the University of Leoben, the Austrian Fire Brigade Association and ILF Consulting Engineers have investigated the effects of e-vehicle fires in tunnel systems. The results are reassuring for passenger cars, but not for commercial vehicles. For the latter, as well as for fires in multistorey car parks, further investigations are urgently needed.

Molecular burdocks: peptides guide self-assembly on the micrometre scale
Chemists demonstrate new approach to self-assembly of colloidal nanoparticles Sometimes even small forces can make comparatively big things happen: In a study in "Angewandte Chemie", scientists from the Faculty of Chemistry at the University of Vienna showed how short peptides can trigger the self-assembly of comparatively large nanoparticles into new structures on the micrometre scale.

Getting the measure of tricky measurements
By Susanne Filzwieser The new Christian Doppler Laboratory for Measurement Systems for Harsh Operating Conditions at TU Graz is conducting research into suitable measurement techniques that can deliver precise results in tough operating and environmental conditions. Although measurement technology has come a long way, established approaches often come up against their limits in difficult operating and environmental conditions, ultimately delivering inaccurate results or even none at all.

BCI Research: Computer Decodes Continuous Movement from Brain Signals
By Christoph Pelzl For the first time ever, the intention of a continuous movement was able to be read out from non-invasive brain signals at TU Graz. This success enables more natural and non-invasive control of neuroprostheses to be carried out in real time. Intended to give paraplegic people back some freedom of movement and thus a better quality of life, so-called brain-computer interfaces (BCIs) measure the person's brain activity and convert the electrical currents into control signals for neuroprostheses.
