An international team led by the University of Geneva has discovered three ultra-massive galaxies in the early Universe forming at unexpected speeds, challenging current models of galaxy formation. An international team led by the University of Geneva has identified three ultra-massive galaxies - nearly as massive as the Milky Way - already in place within the first billion years after the Big Bang.

Using new wearable devices, a team from UNIGE, CHUV, HUG, UNIL and EPFL identifies persistent dysfunctions in glucose regulation in women who have had gestational diabetes. A common complication linked with pregnancy, gestational diabetes increases the risk of developing metabolic disorders, such as type 2 diabetes.

A team from the University of Geneva has discovered the genetic programmes that allow motor neurons to retract from the spinal cord. This discovery opens up prospects for combating neurodegeneration. The motor cortex is made up of neurons responsible for muscle contraction. These neurons have cellular extensions called axons, which project from the cortex into the spinal cord.

Scientists at the University of Geneva, Bern Inselpital and UNIBE have discovered that hidden mutations in non-coding DNA are responsible for the ageing of certain tissues, such as those in the liver. The accumulation of mutations in DNA is often mentioned as an explanation for the ageing process, but it remains just one hypothesis among many.

A team from the University of Geneva and ETH Zurich has shown how the locus coeruleus, a small region of the brain, manages the transition from intense focus to heightened global awareness. What enables our brain to go from intense concentration to a heightened state of alertness? A study carried out by neuroscientists at the University of Geneva , in collaboration with ETH Zurich, shows that a brain region called locus coeruleus (LC) and the neurotransmitter noradrenaline act as conductors, reorganising brain functions according to the mental demands of the moment.

An international team has shown the existence of two distinct populations of sub-Neptunes, resolving a debate in the scientific community. The majority of stars in our galaxy are home to planets. The most abundant are the sub-Neptunes, planets between the size of Earth and Neptune. Calculating their density poses a problem for scientists: depending on the method used to measure their mass, two populations are highlighted, the dense and the less dense.

A team from the University of Geneva shows how visual social skills develop in a unique way in children with autistic disorders. As they grow, children increasingly focus their attention on social elements in their environment, such as faces or social interactions. However, children with autism are often more interested in non-social stimuli, such as textures or geometric shapes.
