At temperatures above 30°C, water loss through transpiration increases in trees, while CO2 uptake decreases - even when there is enough CO2 in the atmosphere. Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL were able to show this in a study conducted using a new high-tech facility.

Freshwater bacteria with small genomes frequently undergo prolonged periods of adaptive stagnation. Based on genomic analyses of samples from Lake Zurich and other European lakes, researchers at the University of Zurich uncovered specific evolutionary strategies that shape these bacteria's lifestyles.

An EPFL scientist along with colleagues from universities across Europe have completed the first-ever quantitative study of the changes that soil organic matter from forests can cause in high-altitude and high-latitude lakes once it's dissolved in the water Treelines are rising around the world as a result of global warming.

In order to understand the Earth's resilience, researchers at ETH Zurich are modelling climate changes from times long past. And they show: Plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth. Over the course of hundreds of millions of years, Earth has lived through a series of climatic shifts, shaping the planet as we know it today.

Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the Universities of Bern and Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats. Exploratory behavior is one of the fundamental personality traits of animals - and these traits influence their probability of survival, among other things.

A team of researchers from EPFL, UNIL, and Unisanté have published a report that goes through about the legacy of pollution from a trash incinerator that burned in the Lausanne Vallon neighborhood from 1958 to 2005.

Researchers at ETH Zurich have engineered bacteria in the laboratory to efficiently use methanol. The metabolism of these bacteria can now be tapped into to produce valuable products currently made by the chemical industry from fossil fuels. To produce various chemicals such as plastics, dyes or artificial flavours, the chemical industry currently relies heavily on fossil resources such as crude oil.

The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into a carbon source, exacerbating the effects of climate change. Open-top chambers (OTCs) in Latnjajaure, Sweden provide a controlled environment to study simulated warming of the tundra ecosystem.

Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests. New research from the Crowther Lab at ETH Zurich illustrates a critical barrier to natural regeneration of tropical forests.

A research team has developed a new type of polymer, the main component of plastics, which is more easily degradable than conventional materials. Mechanical treatment such as grinding, combined with the use of an alkaline solution, is all that's needed to facilitate chemical recycling and reduce environmental impact .

Swiss cities are more likely to accept densification when densification projects provide affordable housing and green spaces compared to densification that is implemented through reduced regulations for housing construction. By prioritizing a socio-ecological densification, extensive planning procedures and delays might be minimized.

Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed. This is one finding of a recent study involving researchers from the University of Basel. It's not the first study on microplastics in Antarctica that researchers from the University of Basel and the Alfred-Wegener Institute (AWI) have conducted.

More than 300,000 meteorites lie on the Antarctic ice. They contain an unprecedented wealth of information about our solar system. With every tenth of a degree of global warming, thousands of meteorites sink. Researchers from WSL and ETH recommend that their collection be promoted. The Antarctic holds a valuable treasure of around 300,000 meteorites lying on the surface of the ice.

Researchers from EPFL and HES-SO Valais Wallis have published a study outlining a path to a more sustainable energy future for Switzerland. The study emphasizes the importance of local energy solutions, and the role of decentralized systems for community empowerment. A pivotal finding of the study, published in Energies , is the integration of decentralized photovoltaic (PV) systems into the Swiss energy grid; this could reduce annual system costs by 10% and elevate self-consumption rates to 68%.

Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade and that three mechanisms are primarily responsible for this.

Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential. Evaporation is a natural process so ubiquitous that most of us take it for granted.

Researchers at ETH Zurich led by Robert Boes are developing specific solutions to optimise electricity production from Swiss hydropower plants. This will ensure that hydropower remains the backbone of Switzerland's electricity supply in the future. "Although Swiss hydropower is a proven technology, we must constantly work on optimising it.

Environmental scientist Alice Pradel cultivates ice cores in the lab to investigate the transport and accumulation of microand nanoplastics. Her aim in doing so is to better understand material flows in the Arctic ice. "Beat the Microbead" is the name of a campaign launched in 2012 with the aim of reducing the use of microplastics in cosmetic products in order to minimise negative effects on the environment and people.

It is important for water management to understand how drought spreads. In a new study, researchers from the WSL Institute for Snow and Avalanche Research SLF show that in every third case, atmospheric drought is followed by low water levels. More rarely does drought have a negative impact on groundwater.

Automated building systems offer a great potential for reducing the energy consumption of properties. Studies on such systems show that optimized solutions can reduce the energy requirements of buildings by around 30 percent on average. In order to avoid the necessity to produce new and emission-heavy computer chips, Empa researcher Hanmin Cai is currently investigating the extent to which damaged smartphones that are no longer used could perform these control and maintenance tasks.
