The Mechanics of the Immune System

Novel microcopy methods allow scientists to study the mechanical interaction of T-cells and particles

04-Jan-2021

When T-cells of our immune system become active, tiny traction forces at the molecular level play an important role. They have now been studied at TU Wien. Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy ...

New cancer diagnostics: A glimpse into the tumor in 3D

In order to analyze tumors, they have to be cut into thin slices. Now, a new technology has been developed that makes pieces of the tumor visible in 3D without cutting them

29-Oct-2020

After cancer surgery, the crucial question is: Are there possibly cancer cells left behind that can continue to grow, or has the entire tumor actually been removed? To find out, the tumor is examined by pathologists. Until now, thin sections were made which were then analyzed under a microscope. ...

COVID-19: Distancing and Masks are not Enough

Decades-old data is being used to describe the propagation of tiny droplets - Now a fluid dynamics team has developed new models

21-Oct-2020

Wear a mask, keep your distance, avoid crowds - these are the common recommendations to contain the COVID-19 epidemic. However, the scientific foundations on which these recommendations are based are decades old and no longer reflect the current state of knowledge. To change this, several ...

The Surprising Stretching Behaviour of DNA

What happens when you pull a DNA molecule? It behaves quite differently than we are used to from macroscopic objects

06-Aug-2020

When large forces, for example in bridge construction, act on a heavy beam, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks in civil engineering. But what happens when you apply these considerations ...

Taking a deep look into animals

04-Jun-2020

Advances in neuroscience research and microscopy: Researchers look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders. Analyses of individual cells in the context of whole organs or tissues is becoming increasingly important in biology. A ...

How to Put Neurons into Cages

Using an acoustic bioprinting technology it was possible to develop multicellular nerve tissue

05-May-2020

Using microscopically fine 3D printing technologies from TU Wien (Vienna) and sound waves used as tweezers at Stanford University (California), tiny networks of neurons have been created. Microscopically small cages can be produced at TU Wien (Vienna). Their grid openings are only a few ...

Neural Hardware for Image Recognition in Nanoseconds

Ultra-fast image sensor with a built-in neural network can be trained to recognize certain objects

06-Mar-2020

Automatic image recognition is widely used today: There are computer programs that can reliably diagnose skin cancer, navigate self-driving cars, or control robots. Up to now, all this has been based on the evaluation of image data as delivered by normal cameras - and that is time-consuming. ...

Bioprinting: Living cells in a 3D printer

22-Oct-2019

With a new process developed at TU Wien (Vienna), living cells can be integrated into fine structures created in a 3D printer - extremely fast and with very high resolution. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a ...

Algal biomass as a raw material for fermentations and for the isolation of valuable sugars

Research team deciphers enzymatic degradation of sugar from marine alga

10-Jul-2019

Enzymes are biocatalysts that are crucial for the degradation of seaweed biomass in oceans. For the first time, an international team of 19 scientists recently decoded the complete degradation pathway of the algal polysaccharide Ulvan by biocatalysts from a marine bacterium. The study was ...

A Chip with Blood Vessels

14-Nov-2018

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way. Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, ...
