The inequalities of low-carbon electricity
A team from the University of Geneva reveals how a low-carbon electricity sector could favour or disadvantage certain regions in Europe. Greenhouse gas reduction, new jobs, new investment opportunities: the benefits of decarbonising the electricity sector - one of the most polluting - are obvious. However, a transition to lower-carbon electricity production could have a negative impact on some regions, depending on their vulnerabilities and their capacity to adapt, while it could have a positive impact on others.

How opioid drugs get into our cells
Unlike natural opioids, opioid drugs penetrate our cells, which explains both their high efficacy and their side effects, reveals a team from the University of Geneva. The human body naturally produces opioid-like substances, such as endorphins, which block the perception of pain and increase the feeling of well-being.

How music can prevent cognitive decline
A team from UNIGE, HES-SO Geneva and EPFL shows the positive impacts of musical activities to counteract brain ageing. Normal ageing is associated with progressive cognitive decline. But can we train our brain to delay this process? A team from the University of Geneva , HES-SO Geneva and EPFL has discovered that practicing and listening to music can alter cognitive decline in healthy seniors by stimulating the production of grey matter.

The unexpected contribution of medieval monks to volcanology
By analysing medieval texts, an international team led by the University of Geneva has succeeded in precisely dating some of the largest eruptions in history. By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers, led by the University of Geneva , drew on readings of 12th and 13th century European and Middle Eastern chronicles, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen.

Tumour avatars to fight colorectal cancer
A team from the University of Geneva has developed a new approach to customize treatments by testing them on artificial tumours. How to determine the most effective treatment for colon cancer? The response to chemotherapy varies greatly from one patient to another. A team from the University of Geneva has developed a new method for testing different drugs, without going through the affected person's body and without resorting to animal experiments.

Diagnosing Alzheimer’s disease with blood biomarkers
An international team led by the University of Geneva and the HUG shows that certain blood biomarkers could facilitate the diagnosis of Alzheimer's disease. An international research team led by the University of Geneva and the HUG has shown that amyloid and tau blood-based biomarkers are highly correlated with the corresponding biomarkers used so far for the diagnosis of Alzheimer's disease.

Allies or enemies of cancer: the dual fate of neutrophils
An international team including scientists from the University of Geneva and Harvard has discovered a new type of immune cell whose action is essential for the success of immunotherapies. Neutrophils infiltrating tumors are heterogeneous and different neutrophil types can have opposing effects on cancer progression.

Shining a light into the ’’black box’’ of AI
An international team led by UNIGE, HUG and NUS has developed an innovative method for evaluating AI interpretability methods, with the aim of deciphering the basis of AI reasoning and possible biases. Researchers from the University of Geneva , the Geneva University Hospitals (HUG), and the National University of Singapore (NUS) have developed a novel method for evaluating the interpretability of artificial intelligence (AI) technologies, opening the door to greater transparency and trust in AI-driven diagnostic and predictive tools.

Sculpting quantum materials for the electronics of the future
An international team led by the University of Geneva has developed a quantum material in which the fabric of space inhabited by electrons can be curved on-demand. Artistic view. Curvature of the space fabric due to the superposition of spin and orbital states at the interface between lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3).

Bypassing antibiotic resistance with a combination of drugs
By combining an antibiotic with an anti-cancer agent, an international team has developed a treatment capable of circumventing the antibiotic resistance of the bacterium Enterococcus faecalis. Antibiotic resistance is one of the world's most pressing health challenges: in 2019, nearly 5 million people died from an infection associated with or attributed to antibiotic resistance.

High-performance detectors to combat spies
A team from the University of Geneva and ID Quantique has developed single-photon detectors with unprecedented performance. These results open new perspectives for quantum cryptography. How can we combat data theft, which is a real issue for society? Quantum physics has the solution. Its theories make it possible to encode information (a qubit) in single particles of light (a photon) and to circulate them in an optical fibre in a highly secure way.

An internal thermometer tells the seeds when to germinate
A team from the University of Geneva has discovered the mechanisms by which the seed decides to remain in 'hibernation' or to trigger its germination depending on the outside temperature. Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable.

How to generate new neurons in the brain
A team of biologists led by UNIGE and UNIL has discovered how to awaken neural stem cells and reactivate them in adult mice. Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood.

Climate: lessons from the latest global warming
By analysing sediments dating back to the global warming that happened 56 million years ago, a team from the University of Geneva is taking a new look at our climate future. PETM was marked by an increase in the seasonality and intensity of rainfall. This increased the mobility of river channels - the deepest areas of a river - and resulted in the transport of large quantities of fluvial clays deposited on adjacent alluvial plains to the deep ocean.

Four classes of planetary systems
A team from the University of Geneva and UNIBE reveals that the distribution of planets can be organised in four different ways around a star. Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers from the Universities of Bern and Geneva, as well as from the National Centre of Competence in Research PlanetS, have now shown for the first time that there are in fact four types of planetary systems.

Tumultuous migration on the edge of the Hot Neptune Desert
A team from the University of Geneva reveals the eventful migration history of planets bordering the Hot Neptune Desert, these extrasolar planets that orbit very close to their star. All kinds of exoplanets orbit very close to their star. Some look like the Earth, others like Jupiter. Very few, however, are similar to Neptune.

Deflecting lightning with a laser lightning rod
A European consortium led by UNIGE, école Polytechnique (Paris), EPFL, hes-so and TRUMPF has managed to guide lightning using a high-power laser installed at the top of Mount Säntis in Switzerland. Forest fires, power cuts and damaged infrastructure..lightning fascinates and destroys in equal measure, causing as many as 24,000 deaths a year worldwide not to mention widespread destruction.

How to turn a tentacle into a foot
By identifying a key regulator of cell identity, a team from the University of Geneva and the FMI has succeeded in modifying the structure and function of tentacle cells in hydra. Humans, animals, plants: all multicellular organisms are made up of specialized cells called differentiated cells. Thus, the cells that make up the epidermis do not have the same identity - nor the same function - as those that line the digestive system, for example.

Managing emotions better could prevent pathological ageing
A team from the University of Geneva deciphers how negative emotions durably modify brain activity in the older adults . Negative emotions, anxiety and depression are thought to promote the onset of neurodegenerative diseases and dementia. But what is their impact on the brain and can their deleterious effects be limited? Neuroscientists at the University of Geneva observed the activation of the brains of young and older adults when confronted with the psychological suffering of others.
