Origami with DNA
Origami with DNA
A team at TU Wien was able to answer important questions about the immune system - with a trick reminiscent of paper folding. T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognise highly specific antigens. Upon detection of an intruder, an immune response is triggered.

More than just a sun tan: ultraviolet light helps marine animals to tell the time of year
More than just a sun tan: ultraviolet light helps marine animals to tell the time of year
Changes in daylength are a well-established annual timing cue for animal behavior and physiology. An international collaboration of scientists led by Kristin Tessmar-Raible at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, now shows that, in addition to daylength, marine bristle worms sense seasonal intensity changes of UVA/deep violet light to adjust the levels of important neurohormones and their behavior.

Graz researchers identify biomarker for cardiovascular diseases
Graz researchers identify biomarker for cardiovascular diseases
By Christoph Pelzl The role of the enzyme dipeptidyl peptidase 3 in the blood pressure-regulating renin-angiotensin system was investigated in the inter-university cooperation project BioTechMed-Graz. The results could pave the way for new therapies for cardio-renal diseases. The renin-angiotensin system (RAS) becomes active at low blood pressure and forms angiotensin II, a hormone that causes blood vessels to constrict, causing blood pressure to rise again.

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

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.

Microbial interactions stabilize carbon in the soil
Microbial interactions stabilize carbon in the soil
Soils play a major role when it comes to the long-term storage of CO2 and the resulting reduction of this gas in the atmosphere - therefore they can contribute to slowing down climate change. In order to gain a better understanding of these mechanisms, it can be helpful to look at the microscopic level of soil microorganisms.
