Using machine-learning methods, researchers at ETH Zurich have shown that more than half of all killer T cells exhibit nuclear invaginations, or folds in the cell’s nuclear envelope. Thanks to this particular cellular architecture, such cells are able to mount a faster and stronger response to pathogens.

Number, size, surroundings and water level: for the first time, there are quantitative scientific recommendations when it comes to the development of new ecological infrastructures for amphibian conservation. A team of researchers from Eawag, WSL and info fauna karch has analysed the optimal conditions for life between water and land. 

At temperatures above 30°C, water loss through transpiration increases in trees, while CO₂ uptake decreases – even when there is enough CO₂ in the atmosphere. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL were able to show this in a study conducted using a new high-tech facility. This finding is important for understanding how trees adapt to climate change and the associated rise in temperatures.

An EPFL scientist along with colleagues from universities across Europe have completed the first-ever quantitative study of the changes that soil organic matter from forests can cause in high-altitude and high-latitude lakes once it’s dissolved in the water.

When the BBC commissioned two reptilian robots from the EPFL BioRob lab for a documentary on the African wilderness in 2016, the researchers could not have predicted how testing the devices in uncontrolled environments would change their approach to robotic design.
