James Webb Space Telescope identifies origins of icy building blocks of life
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discovered the deepest and coldest ice ever detected in such a molecular cloud.

Improving perovskite solar cell resistance to degradation
Improving perovskite solar cell resistance to degradation
Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.

A step towards solar fuels out of thin air
A step towards solar fuels out of thin air
EPFL chemical engineers have invented a solar-powered artificial leaf, built on a novel electrode which is transparent and porous, capable of harvesting water from the air for conversion into hydrogen fuel. The semiconductor-based technology is scalable and easy to prepare. A device that can harvest water from the air and provide hydrogen fuel-entirely powered by solar energy-has been a dream for researchers for decades.

Commercial Dishwashers Destroy Protective Layer in Gut
Commercial Dishwashers Destroy Protective Layer in Gut
Residue from rinse agents is left behind on dishes after they are cleaned in professional-grade dishwashers. This damages the natural protective layer in the gut and can contribute to the onset of chronic diseases, as demonstrated by researchers working with organoids at the Swiss Institute of Allergy and Asthma Research.

Unraveling the secrets of microplastics released by tires
Unraveling the secrets of microplastics released by tires
In Switzerland, tire and road wear particles are one of the biggest sources of microplastics released into the environment, yet the chemical compounds contained in those particles - and their effects - remain largely a mystery. To remedy that knowledge gap, scientists at EPFL and two other Swiss research institutes are conducting a study of the toxicity of tire-particle compounds and how readily they're absorbed by living organisms.

Chemicals could undercut global plastics treaty
Chemicals could undercut global plastics treaty
Next week the UN intergovernmental negotiating committee (INC) on plastic pollution will meet in Uruguay to develop an international legally binding instrument against plastic pollution. There is concern among scientists that the negotiations will overlook the diversity and complexity of chemicals present in plastics.

James Webb reveals the atmospheric secrets of an exoplanet
Thanks to the James Webb Space Telescope, an international team including scientists is building a complete picture of the atmosphere of the planet WASP-39b. The James Webb Space Telescope (JWST) and its unparalleled images of our Universe offer us a new first: by combining several instruments, it draws a molecular and chemical portrait of the atmosphere of the exoplanet WASP-39b.

Liver cancer: How liver cells go astray
Liver cancer is one of the most deadly types of cancer. A team of University of Basel researchers has now uncovered how a healthy liver cell turns into a tumor cell. Comprehensive metabolic changes convert mature liver cells into immature progenitor cells. These cells proliferate rapidly and tumors develop.

Stable membrane for therapeutic carriers
Stable membrane for therapeutic carriers
Cells can generate vesicles as a response to changes in their environment. Although such cell-derived vesicles have great potential for biomedical research, their membrane is fragile and they have tendency to cluster together. Researchers at the University of Basel have successfully introduced a strategy to overcome these issues by equipping the vesicular membrane with a stabilizing shell.

Accurately tracking how plastic biodegrades
Accurately tracking how plastic biodegrades
Researchers at ETH Zurich and Eawag have developed an approach to accurately record and fully track the biodegradation of plastics in soils. Modern agriculture uses a lot of plastic, especially in the form of mulch film that farmers use to cover field soils. This keeps the soils moist for crops, suppresses weeds and promotes crop growth.

Machine learning predicts heat capacities of MOFs
Machine learning predicts heat capacities of MOFs
Chemical engineers at EPFL have developed a machine-learning model that can accurately predict the heat capacity of the versatile metal-organic framework materials. The work shows that the overall energy costs of carbon-capture processes could be much lower than expected. Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores.

Combining forces for the energy transition
Combining forces for the energy transition
The Paul Scherrer Institute PSI and the start-up AlphaSYNT have a common mission. By signing a cooperation and licensing agreement, they aim to commercialise a novel approach to "power-to-gas" conversion, or to be more specific: "power-to-methane". The innovative methanation process developed by PSI will allow energy to be stored as methane gas in future.
