New discovery reveals how diatoms capture CO2 so effectively
Tiny diatoms in the ocean are masters at capturing carbon dioxide (CO2) from the environment. They fix up to 20 percent of the Earth's CO2. A research team at the University of Basel has now discovered a protein shell in these algae that is necessary for efficient CO2 fixation. This groundbreaking discovery can provide ideas for bioengineering approaches to reduce CO2 in the atmosphere.

E-Flower records neuronal activity with electronic petals
Researchers have developed a novel neural recording device called the "e-Flower" that gently wraps organoids in soft petals. Neural spheroids - 3D clusters of brain cells - are emerging as essential tools for understanding neural networks and studying neurological diseases in the lab. EPFL's e-Flower, a flower-shaped 3D microelectrode array (MEA), allows researchers to monitor the electrical activity of these spheroids in a way that was previously impossible.

AI Helps to Detect Antibiotic Resistance
In a pilot study, researchers at the University of Zurich have used artificial intelligence to detect antibiotic resistance in bacteria for the first time. This is an important first step toward integrating GPT-4 into clinical diagnostics. Researchers at the University of Zurich (UZH) have used artificial intelligence (AI) to help identify antibiotic-resistant bacteria.

Biodiversity increases organic nutrient availability across ecosystems
Insects and spiders are important elements in the food webs of aquatic and terrestrial ecosystems. With declines in their biodiversity, the food supply for birds, fish, reptiles, amphibians and small mammals is not only becoming scarcer, but also poorer in important fatty acids, as an international research team led by scientists from Eawag and WSL reports in the journal Science .

Protein interactions: who is partying with whom and who is ruining the party?
Using a new method, researchers at ETH Zurich can measure alterations in the social network of proteins in cells. This work lays the foundation for the development of new drugs to treat diseases such as cancer and Alzheimer's. Inside cells, it's like in a packed dance club: hundreds are partying. Some keep to themselves, others make their way through the crowd, chatting to everyone they meet.

European streamflow data and where to find it
A new catalogue and database of over 17,000 European river catchments facilitates the work of researchers in the field of hydrology. The EStreams project, carried out at Eawag, provides hydrological and meteorological data as well as information on the landscape of the river regions. The records go back up to 120 years.

Inducing plant resistance for sustainable agriculture
Biologists who worked for several years at the University of Neuchâtel report on induced plant resistance in a special multimedia dossier published today in the prestigious journal Frontiers in Science . The method is presented as a kind of vaccination, making it possible to reduce dependence on pesticides not only to combat crop diseases and pests, but also to ensure healthier, more sustainable harvests.

Novel App Tracks Travel-Related Illnesses
On around one in three trips someone falls ill, with gastrointestinal and respiratory complaints among the most common symptoms. These are the findings of a new study based on data from a travel app developed by researchers at the University of Zurich. The app could be used in the future to help detect outbreaks of contagious diseases at an early stage.

Effectiveness of Organised Youth Sports in Switzerland
Maintaining physical activity throughout life is crucial for health and well-being. However, the age-related decline in average physical activity is a challenge. In our study, we found that organised sports, supported by the Swiss Youth+Sports (Y+S) programme, plays an important role in counteracting this trend.

New test improves diagnosis of allergies
Researchers at the University of Bern and Bern University Hospital have developed a test to simplify the diagnosis of allergies. Its effectiveness has now been confirmed in clinical samples from children and adolescents suffering from a peanut allergy. The results could fundamentally improve the clinical diagnosis of allergies in future.

More intense physical activity will help you live longer
As a general rule, regular physical activity is healthy. A research team from the University of Basel has now found that the intensity of the activity impacts the mortality risk. Longevity is all the rage: we all want to live as long as possible while staying healthy. That's why the internet is abuzz with tips on how to achieve this "longevity", be it through fasting, healthy eating, sweat-inducing workouts, yoga or perhaps even meditation.

A novel approach to combat fatty liver disease
Blocking the enzyme ACMSD can significantly reduce damage caused by metabolic liver disease according to a study from EPFL. Metabolic dysfunction-associated steatotic liver disease (MASLD) - previously known as "non-alcoholic fatty liver disease" - affects about 25% of the global population. Its severe form, metabolic dysfunction-associated steatohepatitis (MASH), can lead to liver fibrosis and even liver failure.

A new turn in the fight against cancer
The groundbreaking discovery at the Institute for Research in Biomedicine (IRB) in Bellinzona, affiliated with USI, has revealed, through the study of DNA repair mechanisms, a function of a protein with the ability to fight specific cancerous formations. In Professor Petr Cejka 's laboratory, a team of ten researchers has been studying the mechanisms of DNA repair, a crucial process for preventing diseases such as cancer.

Record-breaking laser pulses
Researchers at ETH Zurich have developed a laser that produces the strongest ultra-short laser pulses to date. In the future, such high power pulses could be used for precision measurements or materials processing. The word laser usually conjures up an image of a strongly concentrated and continuous light beam.

Catastrophically warm predictions are more plausible than we thought
Researchers developed a rating system to evaluate the plausibility of climate model simulations in the IPCC's latest report, and show that models that lead to potentially catastrophic warming are to be taken seriously. What will the future climate be like? Scientists around the world are studying climate change, putting together models of the Earth's system and large observational datasets in the hopes of understanding - and predicting over the next 100 years - the planet's climate.

How catalysts remove dangerous nitrogen oxides
Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual iron atoms sitting in certain neighbouring pores communicate with each other, thereby driving the desired reaction.

Mitigating the consequences of heavy rainfall with Blue-Green Infrastructure
During heavy rainfall, sewage systems are frequently overloaded, leading to untreated wastewater being discharged into surface waters. Modelling techniques used by researchers now show that the volume of such combined sewer overflows could more than triple as a result of climate change However, these studies also reveal that this increase could be avoided through the use of Blue-Green Infrastructure, such as infiltration basins, retention ponds, and porous pavements.

A peak shows the diversity of a forest
Its preservation benefits many others: the umbrella species. This is the role played by the white-backed woodpecker for beetles that feed on dead wood. This rare bird is therefore an indirect indicator of biodiversity, as researchers at BFH-HAFL have shown. Deciduous or mixed forests with lots of dead wood - this is the preferred habitat of the White-backed Woodpecker.

A stiff material that stops vibrations and noise
Materials researchers have created a new composite material that combines two incompatible properties: stiff yet with a high damping capacity. A compressor hums, an air conditioning system rattles, a railway carriage chassis clatters, sending reverberations through its passengers. Vibrations are not only annoying but can also be harmful.

How personal care products affect indoor air quality
An EPFL study has revealed the impact of five common personal care products when they're used in enclosed spaces. Surprisingly, when they come into contact with ozone, the products spark chemical reactions generating new air pollutants. The personal care products we use on a daily basis significantly affect indoor air quality, according to new research by a team at EPFL.
