Road pavements require bitumen as a binder. But its production has many disadvantages. Empa researchers are now experimenting with string, which holds gravel together without the need for concrete - and is also more flexible, more permeable to rainwater and more environmentally friendly.

Tests with recycled asphalt on Swiss roads show promising results. In Uster ZH and on the Lukmanier Pass GR, the proportion of recycled asphalt could be increased without any loss of performance, according to Empa.

Fossil fuels are a thing of the past, the future of mobility is sustainable. Which propulsion systems live up to this claim and also have what it takes to win through on the mass market? An overview.

Using artificial intelligence, researchers supported by the SNSF were able to predict electricity consumption from data on the load of railways and roads.

Earth’s orbit will soon be teeming with new satellites. Companies such as Amazon and Space X want to use them to connect even the remotest corners of the globe to the Internet. Researchers from the Swiss Federal Institute of Technology (ETH) in Zurich recently unveiled how this Internet from space could be optimized even further.

Nobody knows the Ebola virus better than Pardis Sabeti. Viral pandemics are her special area of interest. And now, this genetic researcher is looking for a way out of the Covid crisis. Rock music helps her in that.

Researchers have come up with the vision of a pumped storage power plant of a special kind. Their idea involves a type of cable car that can be used to transport sand or gravel up mountains in order to generate electricity when required by transporting it down the mountain again.

What should one do in a deadlock situation, run over an elderly person or a young child? Such ethical dilemmas take center stage in the public debate relating to self-driving cars. However, there are other much more pressing questions.

A habitat for other celestial bodies – this is the goal behind the second edition of the student project “Igluna” sponsored by ESA. In July, the prototype of the habitat will be erected on Mount Pilatus and remote-controlled from the Swiss Museum of Transport in Lucerne.

Maritime transport accounts for a significant portion of global CO₂ emissions. Commissioned by a shipping company, researchers at the Swiss Federal Institute of Technology in Zurich (ETH) investigated how this could be changed. They see considerable potential in electric propulsion systems and in hydrogen and ammonia-based fuels.
