Es war bisher unbekannt, dass die deutschsprachige Musikhistoriographie dem Komponisten Tomás Luis de Victoria relativ viel Beachtung geschenkt hat. Als iberischer Counterpart des Heroen Palestrina spielt er bei der Gestaltung eines Geschichtsbildes der musikalischen Renaissance daher eine viel wichtigere Rolle als bisher vermutet. Die Auseinandersetzung deutscher Musikwissenschaftler mit Victoria spielte eine zentrale Rolle bei der Würdigung des Komponisten durch die spanische Historiographie.

A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a Yukon ice core ( Eclipse) that is chemically distinct from andesitic 1809 tephra found in Antarctic ice cores indicates a second eruption in the Northern Hemisphere at this time. Together with the similar magnitude and timing of the 1809 volcanic signal in the Arctic and Antarctic, this could suggest a large tropical eruption produced the sulfate and Antarctic tephra and a minor Northern Hemisphere eruption produced the Eclipse tephra. Nonetheless, the possibility that there were coincidental eruptions of similar magnitude in both hemispheres, rather than a single tropical eruption, should not be discounted. Correctly attributing the source of the 1809 volcanic signal has important implications for modeling the magnitude and latitudinal distribution of volcanic radiative forcing.

Bereits zum dritten Mal führte die Private Universität im Fürstentum Liechtenstein UFL im November 2012 ihr jährliches Symposium zum Gesundheitsrecht durch. Dieses Mal beschäftigten sich die Referate mit dem Thema Alter und Altern, und zwar nicht nur aus rechtlicher Perspektive, sondern mit Blick über die Disziplinengrenzen hinaus.

Adaptations to new pollinators involve multiple floral traits, each requiring coordinated changes in multiple genes. Despite this genetic complexity, shifts in pollination syndromes have happened frequently during angiosperm evolution. Here we study the genetic basis of floral UV absorbance, a key trait for attracting nocturnal pollinators. In Petunia, mutations in a single gene, MYB-FL, explain two transitions in UV absorbance. A gain of UV absorbance in the transition from bee to moth pollination was determined by a cis-regulatory mutation, whereas a frameshift mutation caused subsequent loss of UV absorbance during the transition from moth to hummingbird pollination. The functional differences in MYB-FL provide insight into the process of speciation and clarify phylogenetic relationships between nascent species.
