The evolutionary origin of the gut

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal lineage, researchers from ...

Clever cockatoos bend hooks into straight wire to fish for food

In the early 2000s the New Caledonian crow Betty in Oxford shocked the world when she spontaneously bent a hook into a straight piece of wire while trying to retrieve a small out-off-reach basket with a handle from a vertical ...

Physicists measure molecular electronic properties of vitamins

Quantum physics teaches us that unobserved particles may propagate through space like waves. This is philosophically intriguing and of technological relevance: a research team at the University of Vienna has demonstrated ...

Massive particles test standard quantum theory

In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive ...

Magnetic quantum objects in a 'nano egg carton'

Magnetic quantum objects in superconductors, so-called "fluxons," are particularly suitable for the storage and processing of data bits. Computer circuits based on fluxons could be operated with significantly higher speed ...

In both love and war, alligators signal size by bellowing

American alligators produce loud, low-frequency vocalizations called "bellows." Cognitive biologists at the University of Vienna, Stephan Reber and Tecumseh Fitch, investigated these vocalizations and found that they reveal ...

Unbreakable quantum entanglement

Einstein's "spooky action at a distance" persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon ...

A new tool to decipher evolutionary biology

Understanding evolution is one of the cornerstones of biology—evolution is, in fact, the sole explanation for life's diversity on Earth. Based on the evolution of proteins, researchers may explain the emergence of new species ...

Chemically tailored graphene

Graphene is considered as one of the most promising new materials. However, the systematic insertion of chemically bound atoms and molecules to control its properties is still a major challenge. Now, for the first time, scientists ...
