Living in the genetic comfort zone

The information encoded in the DNA of an organism is not sufficient to determine the expression pattern of genes. This fact has been known even before the discovery of epigenetics, which refers to external modifications to ...

Host influences bacterial metabolism

Bacteria are masters in adapting to their environment. This adaptability contributes to the bacteria's survival inside their host. Researchers at the Vetmeduni Vienna now demonstrated that the bacterial pathogen Listeria ...

Avian malaria also affects wild birds in Austria

Avian malaria is not uncommon in Central Europe, as many endemic wild birds are infected with species of Plasmodium, which cause avian malaria. In most cases these blood parasites, transmitted by mosquitoes, do not produce ...

Cichlid sisters swim together in order to reach the goal

The manner and routes of dispersal vary with the species and the ecological conditions. Many fish form shoals to avoid predation. Shoaling with familiar conspecifics affords the fish an even greater advantage by increasing ...

Wolves discriminate quantities better than dogs

Being able to mentally consider quantities makes sense for any social species. This skill is important during the search for food, for example, or to determine whether an opponent group outnumbers one's own. Scientists from ...

Scientists uncover secrets of hibernation

For hibernating mammals, the pre-winter months are a race against time to accumulate enough energy reserves to last until spring. Offspring born late in the year have much less time to achieve this. Scientists from the Research ...

Investigating the "underground" habitat of Listeria bacteria

The literature describes Listeria as ubiquitous bacteria with widespread occurrence. Yet they only become a problem for humans and animals when they contaminate food processing facilities, multiply, and enter the food chain ...
