Brain organoid developed for research
The human brain is not only larger and contains more nerve cells than the control center of other species, it is also networked in a very special way: Thick bundles of nerves connect brain regions like highways over long distances, such as the left and right hemispheres of the brain. A team of researchers at IMBA, in cooperation with MedUni Vienna, has now presented the first organoid model in which these information "highways" can be studied.

Nerve Cells 'Old at Heart'
Nerve Cells ’Old at Heart’
April 5, 2024 New research shows: key molecules within nerve cells persist throughout life Most human nerve cells last a lifetime without renewal. A trait echoed within the cells' components, some enduring as long as the organism itself. New research by Martin Hetzer, molecular biologist and president of the Institute of Science and Technology Austria (ISTA), and colleagues discovered RNA, a typical transient molecule, in the nerve cells of mice that remain stable for their entire lives.

A self-cleaning wall paint
A self-cleaning wall paint
A breakthrough in catalysis research leads to a new wall paint that cleans itself when exposed to sunlight and chemically breaks down air pollutants. Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while - but over time, the colour changes and needs to be renewed.

Ultra-short light pulses enable high-precision 'artificial nose'
Ultra-short light pulses enable high-precision ’artificial nose’
A new spectroscopy method has been developed at TU Wien: Using a series of laser pusles, chemical analyses can be carried out much faster and more precisely than before. Whether you want to analyze environmental samples in nature or monitor a chemical experiment, you often need highly sensitive sensors that can "sniff out" even tiny traces of a certain gas with extreme accuracy.

Micro- and nanoplastics in the body are passed on during cell division
The gastrointestinal tract is already known to researchers as a major storage site for microand nanoplastic particles (MNPs) in the human body. A research consortium consisting of the University of Vienna, the Medical University of Vienna and other partners under the leadership of CBmed GmbH in Graz has now investigated the effects of the tiny plastic particles on cancer cells in the human gastrointestinal tract.

Down to the Core of Poxviruses
Down to the Core of Poxviruses
ISTA researchers uncover the architecture of poxvirus cores A recent re-emergence and outbreak of Mpox brought poxviruses back as a public health threat, underlining an important knowledge gap at their core. Now, a team of researchers from the Institute of Science and Technology Austria (ISTA) lifted the mysteries of poxviral core architecture by combining various cryo-electron microscopy techniques with molecular modeling.

The rock that creates clouds
The rock that creates clouds
Feldspar is very common in rocks. As atmospheric dust, this mineral contributes efficiently to cloud formation. Researchers at TU Wien have now discovered what happens during this process. Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role.

Revolutionary advances in CO2 utilization technology
Revolutionary advances in CO2 utilization technology
Converting the climate-damaging CO2 into usable substances could offer an important approach to tackling the climate crisis. Promising methods have already been developed at the Johannes Kepler University Linz. A new discovery now brings industrial use within reach. Using special catalysts, Assoc. Prof. Wolfgang Schöfberger (JKU Institute of Organic Chemistry) developed a method years ago on a laboratory scale to convert CO2 into industrial alcohol.

Less waste thanks to mechanochemistry
"Chemistry is when it smokes and stinks" is an old saying. But green chemistry shows that things can be done differently . Green chemistry has been firmly established in research at TU Wien for more than a decade. With the inter-university Master's in Green Chemistry, it is now also gaining visibility in teaching.

Two Conductors of a Chemical Reaction
For the first time, researchers at TU Wien have successfully observed the operating principle of so-called promoters in a catalytic reaction in real-time. These promoters play an important role in technology, but so far there is only limited understanding of how they work. Catalysts are essential for numerous chemical technologies, ranging from exhaust gas purification to the production of valuable chemicals and energy carriers.

Aerosols: When scents influence our climate
One of the great unknowns in climate models is the behavior of certain gases that often smell strongly and cause water to condense. TU Wien (Vienna) is providing new insights into this. It has long been clear that man-made greenhouse gases are changing the climate - but there are still important details of climate change that are not well understood.

Interacting polarons
Interacting polarons
In physics, the complex processes in solids are often described in terms of quasiparticles. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now, for the first time, Innsbruck scientists led by Rudolf Grimm have been able to observe in experiments how Fermi polarons - a special type of quasiparticle - can interact with each other.

Art with DNA - Digitally creating 16 million colors by chemistry
The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary sequences. Fluorescent markers bound to one of the matching DNA strands make the duplex visible, and fluorescence intensity increases with increasing duplex stability.

A Longer Life for Organic Solar Cells
A Longer Life for Organic Solar Cells
By Philipp Jarke Photovoltaic cells made of organic materials are light and flexible, which is why they are considered very promising. An international research network led by TU Graz is now aiming to increase the stability of the materials. Solar cells made of silicon have been around for 70 years. Organic solar cells, on the other hand, are quite new, but open up new possibilities for emission-free electricity production.
