Forscher entwickeln mit Spieltheorie These zur Entwicklung der Zusammenarbeit

Moralsysteme sind der Schlüssel zur Unterscheidung zwischen “gut” und “böse” und damit für die Festlegung sozialer Ordnungen elementar. Ein internationales Forschungsteam um den Mathematiker Tatsuya Sasaki von der Universität Wien hat nun eine neue optimale Theorie zur Entwicklung von Zusammenarbeit im Sinne der evolutionären Spieltheorie vorgelegt. Die Wissenschafter haben herausgefunden, dass die moralische Nicht-Bewertung ein effektiver Grundstein beim Aufbau einer Kooperation ist. Die Ergebnisse wurden kürzlich im Fachjournal Scientific Reports veröffentlicht.

When paleontologists at the University of Washington cut into the fossilized jaw of a distant mammal relative, they got more than they bargained for — more teeth, to be specific. (more…)

The truth about Galileo and his conflict with the Catholic Church

By Guest PostMarch 14, 2017Sciencecatholic church, conflict, heliocentrism, henry kelly, truth about galileo

Today virtually every child grows up learning that the earth orbits the sun.

But four centuries ago, the idea of a heliocentric solar system was so controversial that the Catholic Church classified it as a heresy, and warned the Italian astronomer Galileo Galilei to abandon it. (more…)

Toward safer, long-life nuclear reactors: Metal design could raise radiation resistance by 100 times

ANN ARBOR — In findings that could change the way industries like nuclear energy and aerospace look for materials that can stand up to radiation exposure, University of Michigan researchers have discovered that metal alloys with three or more elements in equal concentrations can be remarkably resistant to radiation-induced swelling.

Experiments at Berkeley Lab confirm that structural defects at the periphery are key in catalyst function

Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, a team of researchers working at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Hebrew University of Jerusalem in Israel confirmed with a unique infrared probe.

If you had told me ten years ago that I’d be a Ph.D. student studying solar energy technologies, I would have laughed in your face.

No, really. (more…)

Heat from Earth’s core could be underlying force in plate tectonics

By Guest PostMarch 5, 2017Sciencedavid rowley, east pacific rise, heat, mid ocean ridges, pacific subduction zones, plate dynamics, plate tectonics, underlying force

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. (more…)

Wissenschaftler zeigen, dass die Venusfliegenfalle Stickstoff-Verbindungen ihrer Beute zur Energiegewinnung einsetzt

Die Venusfliegenfalle fängt Insekten nicht nur, um an wertvolle Nährstoffe zu gelangen: Ein Forschungsteam um Prof. Dr. Heinz Rennenberg und Lukas Fasbender vom Institut für Forstwissenschaften der Universität Freiburg hat nachgewiesen, dass die fleischfressende Pflanze aus ihrer Beute auch Energie gewinnt. Die Wissenschaftlerinnen und Wissenschaftler haben ihre Ergebnisse im Fachjournal „New Phytologist“ vorgestellt.
