  • Vulnerable Prehistoric Giants

    The remains of glyptodonts, a group of extinct giant armadillos, indicate that humans spread to South America earlier than previously assumed. Found in northwestern Venezuela, the fractured skulls could represent evidence of hunting by humans, says UZH paleontologist Marcelo Sánchez. Skilled human hunters are also likely to have contributed to pushing the large, heavily armored animals over the brink. More …

    Vegetation Regulates Energy Exchange in the Arctic

    Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. Different plant communities in the tundra play a key role in the energy exchange between land and the atmosphere but are not taken into account in climate models. More …

    Vocal Communication Originated over 400 Million Years Ago

    Acoustic communication is not only widespread in land vertebrates like birds and mammals, but also in reptiles, amphibians and fishes. According to researchers at the University of Zurich, the evolutionary origin of vocal communication dates back more than 400 million years. More …

    A Factory in Outer Space

    It’s possible to produce things in orbit that wouldn’t be possible on Earth, says Oliver Ullrich. We sat down with the biochemist and space physician to learn more about weightless cells, the UZH Space Hub, and humans as an interplanetary species. More …

    Threatened Aldabra Giant Tortoise Genome Decoded

    They can live for more than 100 years and weigh up to 250 kilograms – Aldabra giant tortoises. Researchers at the University of Zurich have now decoded the genome of Aldabrachelys gigantea, one of only two remaining giant tortoise species worldwide. The findings will help to ensure the long-term survival of the threatened species. More …

    New Flight Platform Increases Flexibility in Research

    The 6th Swiss Parabolic Flight Campaign, run by the UZH Space Hub and the Swiss Sky Lab Foundation, takes place at the Air Base Dübendorf from 3 to 14 October. It is the first time a campaign is featuring a Cessna Citation II research aircraft, operated by the Royal Netherlands Aerospace Centre (NLR). The airplane will carry four research projects into weightlessness. More …

  • New UZH Magazin

    The Art of Learning

    Learning is itself a skill that must be learned. The best ways to do this and the requirements for success are current topics of research at UZH. The new UZH Magazin examines how our ability to learn changes over the course of our lives, how good teaching works, and what goes on in our brains when we learn. The current issue is published jointly by the University of Zurich and UZH Alumni. More …

    Longer, Hotter and More Frequent Heat Waves in Swiss Cities

    Hot days followed by sweltering nights without any temperature relief in between might become a new norm towards the end of the 21st century. Researchers from the University of Zurich have analyzed the frequency, intensity and length of such extreme events for five Swiss cities. Lugano and Geneva would be most affected. More …

    Doctor Einstein

    One hundred years ago, Albert Einstein was awarded the Nobel Prize for Physics. Zurich played an important role in the renowned scientist’s career – he was a student here, and in 1905 submitted his dissertation to the University of Zurich. Einstein’s doctoral certificate has now returned to the university and is on permanent display. The new display case containing the diploma was unveiled yesterday. More …

    Frogs Use Brains or Camouflage to Evade Predators

    How do frogs protect themselves from predators? Some species rely on cognitive predator evasion, using their large brains and strong hind legs. For species exposed to high predation pressure, effective camouflage to avoid being detected in the first place may be preferable. More …

    New 3D Model Shows: Megalodon Could Eat Prey the Size of Entire Killer Whales

    International researchers in collaboration with UZH used an exceptionally preserved fossil to create a 3D computer model of the full body of a megadolon. Their results suggest that the megalodon could fully consume prey the size of today’s killer whales. More …

    Global Spread of Powdery Mildew through Migration and Trade

    The worldwide distribution of one of the most important cereal pathogens is the result of human activity. Researchers at the University of Zurich have traced the history and spread of wheat powdery mildew along wheat trade routes and found that mixing of genetic ancestries of related powdery mildew species played a central role in the evolution and adaptation of the pathogen.

    Communication Makes Hunting Easier for Chimpanzees

    Chimpanzees use communication to coordinate their cooperative behavior – such as during hunting. When chimpanzees produce a specific vocalization, known as the “hunting bark”, they recruit more group members to the hunt and capture their prey more effectively. More …
