Sea anemone is genetically half animal, half plant
Sea anemone shows a genomic landscape surprisingly similar to human genome, but also displays regulatory mechanisms similar to plants The team led by evolutionary and developmental biologist Ulrich Technau at the University of Vienna discovered that sea anemones display a genomic landscape with a complexity of regulatory elements similar to that of fruit flies or other animal model systems.

Sometimes the average just isnít good enough
Sometimes the average just isnít good enough
Computational biologists show that averaging is not always a good thing when it comes to analyzing protein crystal structures.

Rewards facilitate human cooperation under natural selection
Rewards facilitate human cooperation under natural selection
A new study, by Faculty of Mathematics postdoctoral fellow Tatsuya Sasaki, provides insights into how voluntary rewarding promotes cooperation in joint enterprises. It may help explain how reward funds rise (and fall) and how rewarding is better than punishing in establishing cooperation. The study is published online in the Royal Society journal "Biology Letters".

Not just clean but spotless - Researchers show how cells tidy up
Not just clean but spotless - Researchers show how cells tidy up
New findings from the team of Claudine Kraft at the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna give insights into how cells dispose of their waste. Malfunctions in this process have been linked to Alzheimer's disease and cancer. The study is published online in the renowned scientific journal Molecular Cell.

The five fingers of our feathered friends: New research results on the evolution of bird wings
The five fingers of our feathered friends: New research results on the evolution of bird wings In general, land vertebrates have five fingers or toes per hand or foot. Many animal groups, however, have modified this recipe in the course of evolution. For example, camels have only two and horses only one fully developed toe.

Monkeys "understand" rules underlying language musicality
Many of us have mixed feelings when remembering painful lessons in German or Latin grammar in school. Languages feature a large number of complex rules and patterns: using them correctly makes the difference between something which "sounds good", and something which does not. However, cognitive biologists at the University of Vienna have shown that sensitivity to very simple structural and melodic patterns does not require much learning, or even being human: South American squirrel monkeys can do it, too.

"Chimpanzees of a feather sit together": Friendships are based on homophily in personality
"Chimpanzees of a feather sit together": Friendships are based on homophily in personality Like humans, many animals have close and stable friendships. However, until now, it has been unclear what makes particular individuals bond. Cognitive Biologists of the University of Vienna, Austria, and the University of Zurich, Switzerland, explored that chimpanzees choose their friends as to be similar in personality.

Capturing brain activity with sculpted light
Capturing brain activity with sculpted light
Researchers in Vienna develop new imaging technique to study the function of entire nervous systems Scientists at the Campus Vienna Biocenter (Austria) have found a way to overcome some of the limitations of light microscopy. Applying the new technique, they can record the activity of a worm's brain with high temporal and spatial resolution, ultimately linking brain anatomy to brain function.

Cockatoos know what is going on behind barriers
How do you know that the cookies are still there although they have been placed out of your sight into the drawer? How do you know when and where a car that has driven into a tunnel will reappear? The ability to represent and to track the trajectory of objects, which are temporally out of sight, is highly important in many aspects but is also cognitively demanding.

Keeping centrioles in check to ensure proper cell division
The duplication of cellular contents and their distribution to two daughter cells during cell division are amongst the most fundamental features of all life on earth.

Cross-talk between signaling cascades
Cross-talk between signaling cascades
Signaling cascades communicate and integrate extracellular signaling cues spatially and temporally via formation of defined protein-protein interactions. Scientists from the Institute of Biochemistry in Innsbruck discovered a unique mechanism which is based on binary protein-protein interactions and which explains cross talk between critically regulated signaling cascades.

The Bee’s Knees for Detecting Disease
Fire blight is a serious threat to fruit trees. Now a quick test has been developed at the Vienna University of Technology, which can indicate the danger early - with the help of bees. When blossoms and leaves wilt and turn black, it is usually too late: the plant disease fire blight damages especially apple trees and pear trees, clearing the affected trees is often the only chance left.

Mould Fungi Can Cure Plants
Genetic research at the Vienna University of Technology (TU Vienna) yields remarkable insights on mould fungi. This opens the door to the specialized use of fungi in agriculture. We know them from our garden, from damp cellars or from the fridge - mould fungi can be found almost everywhere. Their success is due to their remarkable versatility: depending on external conditions, they can choose quite different lifestyles.
