Scientists explore the complexity of rocks within the Earth's crust
A team of scientists has provided insight into the mechanisms at work in geothermal reservoirs located deep underground, known as supercritical reservoirs. Through a combination of computer simulations and lab experiments, they showed that rocks located between five and eight kilometers deep in the Earth's crust are also permeable to fluids.

Reducing Herbivore Damage Using Biodiversity
Pesticides aren't always necessary: researchers at the University of Zurich have conducted a comprehensive field study showing that damage from herbivores can be reduced by using biodiversity within a plant species. Different plant genotypes can cooperate to help fend off herbivorous insects. Just like humans, plants interact with the individuals around them.

New approach can reduce traffic congestion at no extra cost
Engineers at EPFL and ETH Zurich have come up with a new approach for reducing traffic congestion in large cities during rush hour. Their system is designed to be both fair and effective. Rush-hour traffic congestion is a major headache for commuters and a real problem for city planners. Worldwide, a huge amount of time is wasted stuck in traffic.

Biological evaluation of water bodies in a time of climate change
Aquatic invertebrates are used as bioindicators to evaluate the quality of Swiss watercourses. However, climate change is also leading to changes in the species composition of these organisms. Eawag has now investigated the impacts of increasing temperatures on water body evaluations on behalf of the FoeN.

How a bacterium becomes a permanent resident in a fungus
An organism as a tenant in another - in biology, this often works quite well. researchers have now shed light on how such a partnership of a cell in a cell can establish. Endosymbiosis is a fascinating biological phenomenon in which an organism lives inside another. Such an unusual relationship is often beneficial for both parties.

Promising Genotyping Technique for Assessing Antimalarial Drug Efficacy
To estimate the efficacy of antimalarial drugs, distinguishing recurring from new infections is crucial. Researchers from Swiss TPH have now compared five genotyping methods to make this distinction and assessed their impact on drug efficacy. The results, published yesterday in the peer-reviewed journal The Lancet Microbe, could help confirm antimalarial resistance and inform WHO guidelines.

A sub-Earth detected around our neighbouring star Barnard
A team of scientists including researchers from the University of Bern, the University of Geneva and the NCCR PlanetS used the ESPRESSO Spectrograph to discover a sub-Earth mass exoplanet orbiting Barnard's star, the second-closest star system to the Sun. This discovery helps to understand planetary formation around red dwarfs and provides insights into the diversity of planetary systems in our cosmic neighbourhood.

Public Discourse Promotes Socially Responsible Behavior
Public discourse campaigns often promote social responsibility, but do such discussions also impact our market behavior? Economists at the University of Zurich have published a new study that shows that engaging in public discourse increases socially responsible market behavior - regardless of participants' social norms and values.

Stardust in the bathroom
Widespread skin diseases such as psoriasis or neurodermatitis are difficult to treat. Together with an industrial partner, researchers have found an innovative solution: Nanoceramic "stars" create tiny skin lesions and allow therapeutic molecules to reach their site of action. When material scientists look into the stars, they may be able to recognize the future - namely when it comes to stars made of nanoceramics.

New target to treat severe autoimmune disease
Researchers at the University of Basel have made significant progress in understanding a rare but serious immune disease. The team has uncovered critical mechanisms involved in the cellular recycling process, thus providing novel therapeutic approaches. LRBA deficiency is a rare and severe autoimmune disorder that was first described in 2012.

Cities influence precipitation and experience more intense thunderstorms than other regions.
A new study from the University of Lausanne reveals how cities influence precipitation and storms, and are prone in summer to more severe and localized rainfall events than surrounding areas. This phenomenon could lead to an increased risk of flooding in the future, as urban areas expand in line with global warming.

How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. Our DNA is not just a string of genes; it's a complex and dynamic structure where the spatial organization within the nucleus plays a crucial role in regulating which genes are turned on or off.

Kidney stones are often excreted without pain
A research team led by Inselspital, Bern University Hospital, and the University of Bern has shown that a high percentage of kidney stones are excreted without symptoms. This finding should be incorporated into the future treatment of patients with recurrent kidney stones. Kidney stones are caused by the deposition of minerals and salts in the kidneys and can lead to severe pain when passing through the urinary tract.

Unexpected immune response may hold key to long-term cancer remission
Results from a preclinical study in mice, led by EPFL, and a collaborative clinical study in patients show that the type 2 immune response - associated with parasitic infection and thought to play a negative role in cancer immunity - is positively correlated with long-term cancer remission. In 2012, 7-year-old Emily Whitehead became the first pediatric patient to receive pioneering chimeric antigen receptor (CAR-T) therapy to fight the recurrence of acute lymphoblastic leukemia (ALL).

Programming cells to target brain tumours
Scientists from the University of Geneva and HUG have developed CAR-T cells capable of targeting malignant gliomas while preserving healthy tissue. Glioblastoma is the most common and most aggressive primary brain tumour, with an average survival after diagnosis of less than two years, and against which current treatments remain ineffective.

Signs of developing asthma are evident in the first year of life
What factors lead to chronic respiratory disease? Researchers investigated this question using health data from about 780 infants. Their analysis shows that children's risk of developing asthma later in life can be more reliably predicted by observing the dynamic development of symptoms during the first year of life.

NA62 experiment at CERN observes ultra-rare particle decay
Geneva, 25 September 2024. At a seminar held at CERN this week, the NA62 collaboration reported the unequivocal confirmation of the ultra-rare decay of a positively charged kaon into a positively charged pion and a neutrino-antineutrino pair. Experiments including NA62 have previously measured and seen evidence of this process, but this is the first time it has been measured with a statistical significance of five standard deviations , crossing the threshold traditionally required to claim a discovery in particle physics.
