| Plant-based insulation materials as CO2 sinks? |
Empa researchers want to develop a novel type of insulating material from plant-based raw materials or waste products that can permanently bind the carbon dioxide it contains by means of a special heat treatment – and thus act as a CO2 sink. What's more, once the buildings have been deconstructed, this "biochar" and the carbon dioxide it contains can be used in agriculture to increase soil fertility.

Patchwork of issues limits solar expansion
|
Whether rooftop solar panels are worth the cost is largely dependent in Switzerland on local compensation rates for solar power and on electricity prices in general – these are the findings of a study by researchers at ETH Zurich and the University of Bern. Many power grid operators pay too little, thereby limiting the expansion of solar power.

How non-native tree species affect biodiversity
|
Non-native forest tree species can reduce native species diversity if they are planted in uniform stands. In contrast, the effects of introduced species on soil properties are small. This was found by an international review study with the participation of the WSL.

More light in the darkness
|
The Standard Model of particle physics describes our visible universe with incredible precision. Yet researchers are not entirely satisfied with it and are trying to find gaps in the theory. PSI’s unique infrastructures play a key part in their mind-boggling experiments.
