A UNIGE-HUG team demonstrates the value of imaging to detect the presence of tau protein in the brain to predict cognitive decline due to Alzheimer's disease. Alzheimer's disease, one of the most common neurodegenerative diseases, leads to progressive loss of memory and autonomy. It is characterised by the accumulation of neurotoxic proteins in the brain, namely amyloid plaques and tau tangles.

A team from the University of Geneva has identified two key genes whose expression influences cancer progression. Tissues, blood vessels, cells: tumours develop in a complex ecosystem known as the tumour microenvironment. While it is established that this environment differs from one patient to another and that it can have a positive or negative influence on the progress of the disease, the rules that govern tumour microenvironments are still poorly understood.

A team of Swiss and Greek archaeologists recently completed the third season of excavations on the wreck of Antikythera. The wreck of Antikythera was recently brought into the spotlight by the film Indiana Jones and the Dial of Destiny. Far from the cinematic imagination, an international team of archaeologists, divers, engineers and physical and natural scientists is currently excavating the famous wreck.

Fossils of coelacanth discovered in Ticino reveal the existence of an unexpected diversification after the greatest mass extinction in the history of life. The study of a new species of coelacanth from the Middle Triassic period, with a strange morphology for these fish known as "living fossil", show the formation of several species in a short time, after a mass extinction that occurred 252 million years ago, with more than 80% of marine species disappearing.

Harnessing advanced simulation tools, a team of scientists from UNIGE, Northwestern University and University of Florida shed light on the enigmatic nature of these celestial "beasts". Black holes, some of the most captivating entities in the cosmos, possess an immense gravitational pull so strong that not even light can escape.

Thanks to a new technique for observing chemical reactions in liquids, UNIGE and ETH are shedding light on one of the hypotheses about the chemical origins of life. What processes led to the appearance of life on our planet? Some scientists believe that urea played a key role. After being enriched in warm puddles, this small molecule is thought to have been exposed to cosmic rays to produce malonic acid, the source of RNA and DNA.

A team from the University of Geneva and HUG has for the first-time used bacteriophages to successfully treat a patient suffering from an antibiotic-resistant chronic bacterial lung infection.

A team from the University of Geneva has developed the first method for testing together Einstein's and Euler's theories for the accelerating expansion of the Universe and dark matter. The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in which celestial objects distort the Universe.

Scientists have identified a new type of molecular sensor that enables the malaria parasite to infect human cells or mosquitoes at just the right moment. With almost 250 million cases a year, 621,000 of them fatal, malaria remains a major public health problem, particularly in sub-Saharan Africa. Malaria is a parasitic disease transmitted by mosquitoes and caused by a microbe of the genus Plasmodium.

A team from the University of Geneva has worked in an innovative concept for a book for visually impaired children. Children with visual impairment do not perceive the world in the same way as sighted people. As a result, they need specific educational tools, including children's books, that enhance their skills and senses.

A team from the University of Geneva has discovered how the influenza A virus hijacks the mechanism for importing iron into cells to invade its host. Influenza epidemics, caused by influenza A or B viruses, result in acute respiratory infection. They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu.

A team from the University of Geneva shows how specifically modifying gene expression causes feathers to replace scales in the chicken. Scales, spines, feathers and hair are examples of vertebrate skin appendages, which constitute a remarkably diverse group of micro-organs. Despite their natural multitude of forms, these appendages share early developmental processes at the embryonic stage.

Researchers have found strong evidence that supermassive stars can explain the anomalies observed in large clusters of stars. Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows anomalies that are not found in any other population of stars.

A team from the University of Geneva and Beihang University reveals that the FOXI3 gene, responsible for ear development, is involved in Goldenhar syndrome. Goldenhar syndrome is a rare congenital disease, affecting early foetal development. This syndrome includes malformations of varying severity, affecting different parts of the face.

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.

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.

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.

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.

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.

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.
