A Swiss research team has succeeded in increasing the efficiency of perovskite silicon tandem solar cells to over 30 percent. This is a world record.

The sun is likely to become the world's most important source of energy before 2050, according to British scientists. This is the result of an analysis of technological and economic data by the University of Exeter and University College London.

The larvae of a species of beetle native to Central and South America can apparently survive with plastic as their only food source. The larvae's appetite for Styrofoam could be the key to mass plastic recycling.

Cement production is responsible for 9 percent of carbon emissions in Switzerland. Researchers at Empa believe that this can be changed. Even cement production methods that absorb more CO₂ than they emit are on the horizon.

Storing energy for months without loss and using it for heating in winter: researchers have invented a new type of chemical heat storage system that can store large amounts of energy for virtually unlimited periods in an environmentally friendly way.

Viennese complexity researchers have found a method to predict the growth of cities. This could facilitate much more efficient urban development and help conserve resources.

How fast is the ice melting in Antarctica? Autonomous drones and AI could help reduce the uncertainty of sea-level rise.

In a recent study, US scientists suggest using moon dust to combat global warming, since lunar dust shields a lot of sunlight with little mass. Other experts are critical of this method.

Computers powering self-driving cars could be a big contributor to global carbon emissions, according to MIT.

In an Empa research project, study participants rated the noise of new types of aircraft as less annoying than the noise of today's aircraft.
