Antibiotic-resistant bacteria in wastewater
Antibiotic-resistant bacteria are a threat to health worldwide. This makes it all the more important not only to track their spread, but also to recognise trends. Over the course of a year, researchers have analysed wastewater from six wastewater treatment plants in Switzerland for the spread of antibiotic-resistant coliform bacteria.

First Week after Birth Is Critical for Development of Senses
Researchers at UZH have found that the maturation of the senses for smell and touch is closely linked in mice and that this strong interaction takes place within a narrow developmental time window. These findings not only underline the importance of environmental stimuli for brain assembly in early life, but also the interdependent development of the senses.

Fish out of water: How killifish embryos adapted their development
The annual killifish lives in regions with extreme drought. A research group at the University of Basel now reports in "Science" that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.

Not just a sneeze: Pollen increase blood pressure
An estimated one-fifth of the world's population is affected by pollen allergies. Researchers at Swiss TPH and the University of Basel have now discovered that a high concentration of pollen can increase blood pressure in allergy sufferers. It is estimated that around 20% of adults globally are allergic to pollen.

More than sneezing: Pollen increases blood pressure
An estimated one-fifth of the world's population is affected by pollen allergies. Researchers at Swiss TPH have now discovered that high pollen concentrations can increase blood pressure in allergy sufferers. Pollen allergies are thus becoming a growing public health problem, especially as the pollen season is becoming longer and more intense due to climate change.

Scientists map biodiversity changes in the world's forests
A group of EPFL and scientists have mapped the biodiversity in forests worldwide. Their data, when combined with climate projections, reveal trends that could support ecosystem conservation and restoration efforts. According to the latest figures from the Food and Agriculture Organization of the United Nations, forests cover just over 4 billion hectares of the Earth's surface, or one-third of its total land.

Using solar energy to generate heat at high temperatures
Instead of burning coal or oil to produce cement or steel, in the future solar energy could be used for this purpose. Researchers at ETH Zurich have developed a thermal trap that can absorb concentrated sunlight and deliver heat at over thousand degrees Celsius. The production of cement, metals and many chemical commodities requires extremely high temperatures of over a thousand degrees Celsius.

Portable method lets scientists identify plant DNA out in the field
In EPFL's GenoRobotics project, a cross-disciplinary team of students is developing a novel method for identifying plant DNA - one that's faster, cheaper and less energy-intensive than the conventional one. The team hopes their new protocol, designed for use out in the field, will make it easier to categorize plants and ultimately help protect biodiversity.

Mosaic grassland landscapes are the most beneficial
Like forests, grassland provides numerous ecological, economic and social benefits. Researchers in the Swiss canton of Solothurn have investigated ways to maintain and improve these benefits. Grass, clover and herbs are the foundation of Swiss agriculture: two-thirds of Switzerland's agricultural land is grassland, much of which is barely suitable for arable farming.

Reaction of trees to heat unravelled
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.

Limited Adaptability Makes Freshwater Bacteria Vulnerable to Climate Change
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.

How rising treelines can affect Alpine lakes
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.

How the plant world shapes the climate cycle
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.

Curiosity promotes biodiversity
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.

On the trail of pollution in Lausanne
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.

Bacteria for climate-neutral chemicals of the future
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.

Understanding carbon release from the tundra
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.

Tropical forests can’t recover naturally without fruit eating birds
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.

Will plastics soon be easier to degrade?
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 .
