Reaching your life goals as a single-celled organism
Reaching your life goals as a single-celled organism
How do simple creatures manage to move to a specific place? Artificial intelligence and a physical model from TU Wien can now explain this. How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails.

Tracking down the tiniest of forces: how T cells detect invaders
Tracking down the tiniest of forces: how T cells detect invaders
T cells use their antigen receptors like sticky fingers - a team from TU Wien and MedUni Vienna was able to observe them doing so. T-cells play a central role in our immune system: by means of their so-called T-cell receptors (TCR) they make out dangerous invaders or cancer cells in the body and then trigger an immune reaction.

Marmoset monkeys have personalities too
Marmoset monkeys have personalities too
In humans, differences in personalities have been evident since the ancient times. Personality in animals has long been ignored, but recently this question has received increasing research interest as it has been realized that personality has evolutionary and ecological significance. An international team of behavioral biologists from Austria, Brazil and the Netherlands, with Vedrana ¦lipogor from the University of Vienna as leading author of the study, designed a set of tasks to assess personality of common marmosets.

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.

Unusual sex chromosomes of platypus, emu and duck
Unusual sex chromosomes of platypus, emu and duck
Three papers unveil the extraordinary diversity of animal sex chromosomes The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually appear as one pair of morphologically different chromosomes between sexes. For example, women have one pair of XX chromosomes, while men have one pair of XY chromosomes.

Graz researchers identify biomarker for cardiovascular diseases
Graz researchers identify biomarker for cardiovascular diseases
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.
