Symbionts sans frontieres: Bacterial partners travel the world
Symbionts sans frontieres: Bacterial partners travel the world
This pandemic year has seen us confined to our homes and restricted from travelling the world. Not so for some microscopic bacteria in the ocean: Throughout the globe, they partner up with clams from the family Lucinidae, which live unseen in the sand beneath the shimmering blue waters of coastal habitats.

Bacterial survival kit to endure in soil
Bacterial survival kit to endure in soil
Soil bacteria have amazing strategies to attain energy in order to withstand stressful times Soils are one of the most diverse habitats on the planet. There are more than thousand microbial species per gram that significantly influence numerous environmental processes. However, the majority of these organisms are believed to be in a state of 'dormancy' due to environmental stress, such as nutrient-poor conditions.

New insights into aortic dissection
New insights into aortic dissection
Aortic dissection is a life-threatening tear in the aortic wall. At present, little is known about the causes. Researchers at TU Graz have now developed algorithms and models designed to support early-stage diagnosis and treatment. Images for download at the end of the message. In most cases, aortic dissection is the result of a tear in the inner layer of the aortic wall, the intima.

Bacteria hijack latent phage of competitor
Bacteria hijack latent phage of competitor
Biochemists discover highly selective phage activation based on signal molecule Bacteriophages are still a relatively unknown component of the human microbiome. However, they can play a powerful role in the life cycles of bacteria. Biochemist Thomas B÷ttcher from the University of Vienna and PhD candidate Magdalena Jancheva were able to show for the first time how Pseudomonas bacteria use a self-produced signal molecule to selectively manipulate phages in a competing bacterial strain to defeat their enemy.

Meiosis: Mind the gap
Meiosis: Mind the gap
Meiosis is a specialized cell division process required to generate gametes, the reproductive cells of an organism. During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange parts of their DNA in a process called meiotic recombination. In order to mediate this exchange of genetic material, cells introduce double strand breaks (DSBs) into their chromosomal DNA.

Crystalline supermirrors for trace gas detection in environmental science and medicine
Crystalline supermirrors for trace gas detection in environmental science and medicine
In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating high-performance laser mirrors in the sensing-relevant mid-infrared wavelength range that absorb less than ten out of a million photons.

A sulfosugar from green vegetables promotes the growth of important gut bacteria An international team of scientists led by microbiologists Alexander Loy from the University of Vienna and David Schleheck from the University of Konstanz has uncovered new metabolic capabilities of gut bacteria. For the first time, the researchers have analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose.

Fear of COVID-19 : Psychological, not environmental factors are important
Fear of COVID-19 : Psychological, not environmental factors are important
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population's response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors that help to maintain high perceived levels of health during restrictions.

Promising metallodrug candidate for tumour therapy
Promising metallodrug candidate for tumour therapy
BOLD-100/KP1339 is a ruthenium-based anticancer agent that has been decisively co-developed at the University of Vienna and which has shown promising results in clinical trials in cancer patients. However, the mode of action of this metal compound has not yet been fully elucidated. Researchers from the University of Vienna and the Medical University of Vienna have now been able to demonstrate that BOLD-100 binds to ribosomal proteins in tumour cells.

The therapeutic potential of peptides
The therapeutic potential of peptides
Currently there are more than 80 peptide drugs on the global market and about twice as many in clinical development. Due to their beneficial properties, these biomolecules play already an important role in the treatment of diseases such as diabetes, cancer, hormone disorders, HIV infection, and multiple sclerosis.

Cardiovascular diseases: New computer model improves therapy
Using mathematical image processing, scientists at the BioTechMed-Graz research cooperation have found a way to create digital twins from human hearts. The method opens up completely new possibilities in clinical diagnostics. Additional Images for download at the end of the text Although treatment options are constantly improving, cardiovascular diseases are still one of the most frequent causes of death in Europe.

Resistant rice plants: TU Graz identifies bacterium that protects rice plants against diseases
Resistant rice plants: TU Graz identifies bacterium that protects rice plants against diseases
With their expertise in microbiome research, the researchers at the Institute of Environmental Biotechnology were able to demonstrate how a specific bacterium inside the seeds of rice plants effectively and in an eco-friendly way inhibits destructive plant pathogens. Rice is the staple food of about half the world's population.
