Relativitätstheorie auch in anderen Forschungsbereichen anwendbar

Einsteins Allgemeine Relativitätstheorie feiert heuer ihren 100. Geburtstag. Selbst heute noch fasziniert sie PhysikerInnen und Laien zugleich. Eine internationales Team um Časlav Brukner von der Universität Wien, Igor Pikovski von der University of Harvard und WissenschafterInnen von der University of Queensland haben nun entdeckt, dass die Relativitätstheorie auch ein ganz anderes, ungewöhnliches Phänomen erklären kann: den Übergang von der Quantenmechanik zu unserer alltäglichen, klassischen Welt. Die Forschungsergebnisse erscheinen im Journal “Nature Physics”. (more…)

Cryo electron microscope enables scientists to explore the frontiers of targeted antibiotics

Researchers at UCLA’s California NanoSystems Institute have become the first to produce images of the atomic structures of three specific biological nanomachines, each derived from a different potentially deadly bacterium — an achievement they hope will lead to antibiotics targeted toward specific pathogens.

New research suggests insect wings might serve gyroscopic function

Gyroscopes measure rotation in everyday technologies, from unmanned aerial vehicles to cell phone screen stabilizers.

Though many animals can move with more precision and accuracy than our best-engineered aircraft and technologies, gyroscopes are rarely found in nature. Scientists know of just one group of insects, the group including flies, that has something that behaves like a gyroscope — sensors called halteres, clublike structures that evolved from wings.

Forschern um Physiker Roland Wester gelang es erstmals, einen elementaren Stoßprozess zwischen Atomen und geladenen Molekülen bei tiefen Temperaturen präzise zu vermessen und zu beschreiben. Das Experiment, bei dem nur ein einziges Quant an Energie in die Drehbewegung des Moleküls übertragen wird, stimmt sehr genau mit theoretischen Berechnungen überein. (more…)

Biologically inspired engineering: Sea sponge anchors are natural models of strength

The Venus’ flower basket sea sponge has hair-like appendages that hold it in place on the sea floor. Research led by Brown University engineers shows that the internal structure of those fibers is fine-tuned for strength. The findings from this natural system could inform the engineering of load-bearing structural members. (more…)
