    Acids against viruses

    A new study by various Swiss universities shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air – with profound implications for virus transmission and strategies to contain it.

  • 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.

    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.

    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.

    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.

    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.

    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.

    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.

    Individual Cells Are Smarter Than Thought

    Humans make decisions based on various sensory information which is integrated into a holistic percept by the brain. But how do single cells make decisions? Much more autonomously than previously thought, as researchers from the University of Zurich have now shown. Cells base their decisions not only on outside signals like growth factors, but also on information they receive from inside the cell. This can even lead to treatment-resistant cancer cells.

    Watch dolphins line up to self-medicate skin ailments at coral “clinics”

    If a human comes down with a rash, they might go to the doctor and come away with some ointment to put on it. Indo-Pacific bottlenose dolphins get skin conditions, too, but they come about their medication by queuing up nose-to-tail to rub themselves against corals. In the journal iScience on 19 May, researchers show that these corals have medicinal properties, suggesting that the dolphins are using the marine invertebrates to medicate skin conditions.

    Satellite Monitoring of Biodiversity Moves Within Reach

    Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers from the universities of Zurich and Montréal have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring.

    Previously Unknown Dolphin Species Was Present in Switzerland

    Twenty million years ago, the Swiss Plateau region, or “Mittelland”, was an ocean in which dolphins swam. Researchers at the University of Zurich’s Paleontological Institute have now discovered two previously unknown species related to modern sperm whales and oceanic dolphins, which they identified based on ear bones.

    Complex Human Childbirth and Cognitive Abilities a Result of Walking Upright

    Childbirth in humans is much more complex and painful than in great apes. It was long believed that this was a result of humans’ larger brains and the narrow dimensions of the mother’s pelvis. Researchers at the University of Zurich have now used 3D simulations to show that childbirth was also a highly complex process in early hominins species that gave birth to relatively small-brained newborns – with important implications for their cognitive development.

    Fossil Treasures of the Alpstein

    A new special exhibition at the University of Zurich’s Zoological and Paleontological Museum showcases sublime fossils found in the Alpstein massif in eastern Switzerland, taking visitors on a journey through time to the marine wildlife of the Cretaceous and Eocene more than 100 million years ago. The exhibition, conceived by the Natural History Museum in St.Gallen, is based on a book by UZH paleontologist Christian Klug and Peter Kürsteiner.

    A Single Gene Controls Species Diversity in an Ecosystem

    To test if a single gene could affect an entire ecosystem, a research team of the University of Zurich conducted a lab experiment with a plant and its associated ecosystem of insects. They found that plants with a mutation at a specific gene foster ecosystems with more insect species. The discovery of such a “keystone gene” could change current biodiversity conservation strategies.

    Popular Male Dolphins Produce More Offspring

    The reproductive success of male dolphins is not determined by strength or age, but via social bonds with other males. The better integrated males are in their social network, the more offspring they produce, a new study by an international team of researchers led by the University of Zurich has shown using long-term behavioral and genetic data.

    Astrocyte Networks in the Mouse Brain Control Spatial Learning and Memory

    Astrocytes form large networks of interconnected cells in the central nervous system. When these cell-to-cell couplings are disrupted in the brain of adult mice, the animals are no longer able to store spatial information. The astrocytes network is thus essential for spatial learning and memory formation, as neuroscientists of the University of Zurich now show.

    Illuminating Real-Time Brain Dynamics of Neuropeptides with a Fluorescent Biosensor

    Neuropeptides play fundamental roles in modulating cellular and circuit functions within the brain. One such signaling molecule – orexin – regulates arousal and wakefulness, and its failure can lead to constant daytime sleepiness (narcolepsy). University of Zurich researchers have now developed a fluorescent orexin biosensor to observe this molecule "live" in the living mouse brain.

    Arctic Winter Warming Causes Cold Damage in the Subtropics of East Asia

    Due to climate change, Arctic winters are getting warmer. An international study by UZH researchers shows that Arctic warming causes temperature anomalies and cold damage thousands of kilometers away in East Asia. This in turn leads to reduced vegetation growth, later blossoming, smaller harvests and reduced CO2 absorption by the forests in the region.
