- 16.05.2013Sea level: one third of its rise comes from melting mountain glaciers
About 99% of the world’s land ice is stored in the huge ice sheets of Antarctica and Greenland, while only 1% is contained in glaciers. However, the meltwater of glaciers contributed almost as much to the rise in sea level in the period 2003 to 2009 as the two ice sheets: about one third. This is one of the results of an international study with the involvement of geographers from the University of Zurich.

In the last thirty years, vegetation has changed significantly the world over. Until recently, the extent to which the climate or humankind was responsible remained unclear. However, geographers from the University of Zurich and colleagues from the Netherlands now reveal that over half of these changes are climatological, humans or as yet unknown human-climate interactions cause over a third and around ten percent cannot be explained fully by either the climate or human activity.

Researchers at Wits University in South Africa, including Peter Schmid from the University of Zurich, have described the anatomy of a single early hominin in six new studies. Australo-pithecus sediba was discovered near Johannesburg in 2008. The studies in Science demon-strate how our two million year old ancestor walked, chewed and moved.

For the first time, researchers from the Centre for Evolutionary Medicine at the University of Zurich together with colleagues abroad have been able to provide evidence of periodontitis, tooth decay and accident-related dental damage in the ice mummy ‘Ötzi’. The latest scientific findings provide interesting information on the dietary patterns of the Neolithic Iceman and on the evolution of medically significant oral pathologies.

Like humans, mice can become infected with Borrelia. However, not all mice that come into contact with these bacteria contract the dreaded Lyme disease: Animals with a particular gene variant are immune to the bacteria, as scientists from the universities of Zurich and Lund demonstrate. Wild mice are the primary hosts for Borrelia, which are transmitted by ticks. More... - 27.03.2013The placodonts are fellow Europeans
Placodonts were among the first marine reptiles. With their trademark crushing teeth, they fed on shellfish and crustaceans. However, when and where these highly specialized marine reptiles originated remained unclear until now. A 246-million-year-old skull of a juvenile placodont was recently discovered in the Netherlands. Paleontologists from the universities of Zurich and Bonn have now proved that it is one of the earliest examples of this saurians and that it originated in Europe.

Incorrect or poor protein regulation can lead to uncontrolled growth and thus cancer or chronic inflammation. Members of the Institute of Veterinary Biochemistry and Molecular Biology from the University of Zurich have identified enzymes that can regulate the activity of medically important proteins. Their discovery enables these proteins to be manipulated very selectively, opening up new treatment methods for inflammations and cancer. More...
