The “tiki-taka”-style of the Spanish national football team is amazing to watch: Xavi passes to Andrès Iniesta, he just rebounds the ball once and it’s right at Xabi Alonso’s foot. The Spanish midfielders cross the field as if they run on rails, always maintaining attention on the ball and the teammates, the opponents chasing after them without a chance.
The striker has to divide his attention: He has to attend to the goalkeeper, but also to player #3 who might block his shot. By splitting his ‘spotlight of attention’ he stays on top of the situation. To ensure that his information processing capacities are not overtaxed he is able to suppress the irrelevant information next to and between his two attentional foci. This provides him with all the necessary information in optimal quality and without distraction. This process is visualized in the picture through various degrees of blurriness.

An international team of scientists from the German Primate Center and McGill University in Canada, including Stefan Treue, head of the Cognitive Neuroscience Laboratory, has now uncovered how the human brain makes such excellence possible by dividing visual attention: The brain is capable of splitting its ‘attentional spotlight’ for an enhanced processing of multiple visual objects. (Neuron, doi: 10.1016/j.neuron.2011.10.013)
When we pay attention to an object, neurons responsible for this location in our field of view are more active then when they process unattended objects. But quite often we want to pay attention to multiple objects in different spatial positions, with interspersed irrelevant objects. Different theories have been proposed to account for this ability. One is, that the attentive focus is split spatially, excluding objects between the attentional spotlights. Another possibility is, that the attentional focus is zoomed out to cover all relevant objects, but including the interspersed irrelevant ones. A third possibility would be a single focus rapidly switching between the attended objects.
This multi-tasking allows us to simultaneously attend multiple objects”, Stefan Treue says. Such a powerful ability of our attentive system is one precondition for humans to become perfect football-artists but also to safely navigate in everyday traffic.Original Publication

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
