Social network of synapses controls their actions

Nerve cells in the brain receive thousands of synaptic signals via their "antenna", the so-called dendritic branch. Permanent changes in synaptic strength correlate with changes in the size of dendritic spines. However, it was previously unclear how the neurons implement these changes in strength across several synapses that are close to each other and active at the same time. Researchers from the University Hospital Bonn (UKB), the University of Bonn, the Okinawa Institute of Science and Technology Graduate University (OIST) and the RIKEN Center for Brain Science (CBS) assume that the competition between spines for molecular resources and the spatial distance between simultaneously stimulated spines affect their resulting dynamics. The results of the study have now been published in the journal "Nature Communications".

Researchers create an “imprint” on a super photon

Thousands of light particles can merge into a type of “super photon” under certain conditions. Researchers at the University of Bonn have now been able to use “tiny nano molds” to influence the design of this so-called Bose-Einstein condensate. This enables them to shape the speck of light into a simple lattice structure consisting of four points of light arranged in quadratic form. Such structures could potentially be used in the future to make the exchange of information between multiple participants tap-proof. The results have now been published in the journal Physical Review Letters.

UNOOSA and University of Bonn renew partnership

The United Nations Office for Outer Space Affairs (UNOOSA) and the University of Bonn have renewed their partnership, reinforcing their commitment to leveraging space technology in response to growing threats from natural and human-made disasters. This five-year agreement, signed today in Vienna, extends the "Spaceborne Earth Observation Applications for Emergency Response and Disaster Risk Reduction" (SPEAR) project, focusing on African nations.

University of Bonn at GAIN24 in San Francisco

The University of Bonn was represented by some high-level figures at this year’s GAIN Conference in San Francisco. Rector Professor Michael Hoch and Vice Rector Professor Birgit Ulrike Münch attended the congress of the German Academic International Network (GAIN) between August 23 and 25. The conference is the largest networking event for international academic careers in Germany.

Environmental policy in Brazil leads to less violence

In December 2007, the then Brazilian government passed a law to curb the illegal destruction of the rainforest. A study by researchers from the Insper Research Institute in São Paulo and the University of Bonn now shows an interesting side effect: where the measures were implemented, not only did deforestation decrease, but so did the number of homicides. The results have now been published in the Journal of Institutional Economics.

Strength Training Activates Cellular Waste Disposal

The elimination of damaged cell components is essential for the maintenance of the body’s tissues and organs. An international research team led by the University of Bonn has made significant findings on mechanisms for the clearing of cellular wastes, showing that strength training activates such mechanisms. The findings could form the basis for new therapies for heart failure and nerve diseases, and even afford benefits for manned space missions. A corresponding article has been published in the latest issue of the journal Current Biology.

Gene scissors switch off with built-in timer

CRISPR gene scissors, as new tools of molecular biology, have their origin in an ancient bacterial immune system. But once a virus attack has been successfully overcome, the cell has to recover. Researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with researchers from the Institut Pasteur in France, have discovered a timer integrated into the gene scissors that enables the gene scissors to switch themselves off. The results of the study have been published in the renowned journal "Nucleic Acids Research".

Anti-ageing and increased mental capacity through cannabis

A low-dose long-term administration of cannabis can not only reverse aging processes in the brain, but also has an anti-aging effect. Researchers from the University Hospital Bonn (UKB) and the University of Bonn together with a team from Hebrew University (Israel) have now been able to show this in mice. They found the key to this in the protein switch mTOR, whose signal strength has an influence on cognitive performance and metabolic processes in the entire organism. The results are now presented in the journal "ACS Pharmacology & Translation Science".
