Alien plant species are spreading rapidly in mountainous areas

Until now, mountain regions have been largely spared from biological invasions. But a new monitoring study shows that alien plants are spreading rapidly to higher altitudes along transport routes worldwide.

How grasses avoid inbreeding

ETH Zurich researchers have been able to show which genes inhibit self-fertilisation in grasses. Plant scientists can now use this mechanism in a more targeted way to breed new varieties of forage grasses as well as rice or barley.

Immediate uptick in investment needed to reach net zero

A new study by ETH Zurich researchers reveals that if Europe fails to immediately invest 302 billion euros in climate-relevant infrastructure, it will not reach its target of net-zero greenhouse gas emissions by 2050.

EPFL holds a giant hackathon on sustainability

With its Solutions4Sustainability initiative, EPFL aims to channel its community members’ knowledge and skills towards the goal of promoting more environmentally friendly lifestyles. To that end, projects selected under the initiative will be granted a hefty chunk of funding.

An eye on reconstruction in Ukraine

Ukrainian building materials professor Viacheslav Troian left his homeland with his family because of the war. At ETH Zurich, he is researching the role that recycled concrete might play in future reconstruction.

Producing fertiliser without carbon emissions

Researchers at ETH Zurich and the Carnegie Institution for Science have shown how nitrogen fertiliser could be produced more sustainably. This is necessary not only to protect the climate, but also to reduce dependence on imported natural gas and to increase food security.
