Dust accumulating on solar panels is a big problem. But washing the panels consumes large amounts of water. MIT engineers have now developed a waterless cleaning method.

A new web tool called “Carculator” determines the ecological footprint of vehicles with different types of propulsion. According to the Paul Scherrer Institute (PSI) in Switzerland, the calculations are intended to serve as a decision-making aid when purchasing a car.

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.

The leading shipping associations intend to establish an international fund with a volume of five billion US dollars to drive forward the reduction of CO2 emissions – the German Shipowners’ Association (VDR) announced.

Biodiversity is declining rapidly. In order to recognise species worthy of protection in time, a research group from Fribourg wants to combine artificial intelligence, image data and citizen science.

Sustainable electronic elements can be made from wood. This is helped by a novel process that uses a laser to engrave electrically conductive tracks into veneers.

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 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.
