Flight ticket prices could rise by 50 percent if aviation is made climate-neutral. This is an estimate from a new study by researchers at ETH Zurich. It is based in particular on the use of synthetic fuels.

A recent study examined how training programs for Indian women working in agriculture can be improved. ETH student Alicia Luther found that effective trainings should be held in a participative and demand-driven way. A participative methodology is key to include participants’ topics of interest, making the potential for adoption higher.

On the Pic du Midi in the Pyrenees, ETH Zurich researchers have analysed particulate matter, clouds and rainwater for traces of arsenic. Using newly developed measurement methods, they have elucidated the transport pathways of the environmental toxin in the atmosphere.

Daria Odermatt and Helena Ström are the winners of this year's Swiss Forum for International Agricultural Research (SFIAR) award. Both Odermatt's and Ström's research offers promising pathways to healthier plants and increased yields for smallholder farmers in Africa.
