Bats Use Second Sense to Hunt Prey in Noisy Environments
AUSTIN, Texas — Like many predators, the fringe-lipped bat primarily uses its hearing to find its prey, but with human-generated noise on the rise, scientists are examining how bats and other animals might adapt to find their next meal. According to a new study, when noise masks the mating calls of the bat’s prey, túngara frogs, the bat shifts to another sensory mode—echolocation. (more…)
Hunt for ninth planet reveals new extremely distant Solar System objects
Washington, DC — In the race to discover a proposed ninth planet in our Solar System, Carnegie’s Scott Sheppard and Chadwick Trujillo of Northern Arizona University have observed several never-before-seen objects at extreme distances from the Sun in our Solar System. Sheppard and Trujillo have now submitted their latest discoveries to the International Astronomical Union’s Minor Planet Center for official designations. A paper about the discoveries has also been accepted to The Astronomical Journal. (more…)
Wenn Wasser zum Zerreißen gespannt ist
Computersimulation erlaubt Einblick in Dampfblasen auf molekularer Ebene
Wasser kann über lange Zeit einer beachtlichen Zugbelastung standhalten. Dies ist eine Voraussetzung für wichtige biologische Prozesse wie etwa den Wassertransport in Bäumen. Experimente über die Stabilität von Wasser unter Zugbelastung kamen bis dato jedoch zu stark unterschiedlichen Resultaten. PhysikerInnen um Christoph Dellago von der Universität Wien entwickelten mit Hilfe von Computersimulationen ein mikroskopisches Modell, das die Stabilität von Wasser abhängig von der angelegten mechanischen Spannung quantitativ vorhersagt. Dabei zeigte sich, dass die Zugstabilität von Wasser höher ist als bisher angenommen. Die aktuelle Studie erscheint im Fachmagazin “PNAS”. (more…)
‘Perfect’ soap molecule
Discovery could have major impact on multibillion-dollar cleaning products industry
A team of researchers, led by the University of Minnesota, has invented a new soap molecule made from renewable sources that could dramatically reduce the number of chemicals in cleaning products and their impact on the environment. (more…)
Earthquakes, ‘Marsquakes,’ and the possibility of life
A new study shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen — a finding that suggests similar seismic activity on Mars may produce enough hydrogen to support life. (more…)
Offenheit hinterlässt Eindruck
Junge Unternehmen, die sich den Prinzipen von „Open Strategy“ verschreiben, erhalten mehr Aufmerksamkeit und wirken vertrauenswürdiger. Das zeigen Leonhard Dobusch vom Institut für Organisation und Lernen und Thomas Gegenhuber von der JKU Linz in der Fachzeitschrift „Long Range Planning“. Dazu zeichneten die Wissenschaftler den „offenen Weg“ von zwei Start-Up-Unternehmen nach. (more…)
Keep Your Spirit Up and Stress Level Down for the Holidays
When the holidays descend upon us, we find ourselves simultaneously excited and bracing for the stress that is rushing toward us. As children, we only had to look forward to all the magic and festivities that awaited. As adults, we have become the facilitators of all of those festivities, working too hard to get them right.
