Fluoride in groundwater: global map shows all risk areas for the first time

Researchers from ETH Zurich discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed.

Crystals consisting of wildly mixed ingredients - so-called high-entropy materials - are currently attracting growing scientific interest. Their advantage is that they are particularly stable at extremely high temperatures and could be used, for example, for energy storage and chemical production processes. An Empa team is producing and researching these mysterious ceramic materials, which have only been known since 2015.

Researchers at the University of Bern have investigated how organic, biodynamic and conventional management in vineyards affects insect fauna. They were able to show that organic - and to a lesser extent biodynamic - management provides better habitat conditions for insects than conventionally managed vineyards.

Most vaccines require constant refrigeration during shipment to remain effective. An international research team led by ETH Zurich has now developed a special hydrogel that vastly improves the shelf life of vaccines, even without refrigeration. The development could save many lives and lower the cost of cold chains.
