Turtles, bears and crocodiles. Tropical forests, fathomless caves and precipitous ice cliffs. These are just some of the many fascinating motifs captured on camera in the underwater photography of Michel Roggo. The Swiss photographer has traveled the world to take pictures of all major freshwater types. An exhibition in the Zoological Museum of the University of Zurich featuring over 900 of his photos presents a beautiful underwater world awash with light.

An international research team has revealed a novel mechanism for the perception of endogenous peptides by a plant receptor. The discovery of this activation mechanism sets a new paradigm for how plants react to internal and external cues. The study ‘Mechanisms of RALF peptide perception by a heterotypic receptor complex’ was published today in the journal Nature.

Following a stroke, antibodies that inhibit the signaling molecule Nogo-A can help repair blood vessels in the affected brain regions. This also promotes the regaining of motor functions, researchers at the University of Zurich have shown in a mouse model. The study opens up new avenues for treatment.

The more money there is in a lost wallet, the more likely it is to be returned to its owner, researchers from the Universities of Zurich, Michigan and Utah show in a global study. They explain the surprising result with the fact that dishonest finders have to adapt their self-image, which involves psychological costs that can exceed the material value of the wallet.

Certain membrane proteins specialise in transporting molecules out of cells - a problem for the efficacy of cancer medication and antibiotics.

When they graze, goats, sheep and cows often ingest bits of earth that can be damaging to their teeth. Researchers from the University of Zurich have now shown how the animals protect themselves against dental abrasion: Their stomach system rinses dust and sand off the ingested food before it is chewed for the second time.

The Swiss Data Cube (SDC) is an innovative technology that gathers all available satellite images from the American Landsat program and the European Sentinel 1 and 2. UNEP/GRID-Geneva, the University of Geneva (UNIGE), the University of Zurich (UZH) and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) have entered a new cooperation agreement to foster the use of Earth Observation data for environmental monitoring at national scale.
