By identifying a protein that helps regulate blood glucose and lipids, researchers at UNIGE hope for the rapid development of treatments more effective than current insulin therapy. Insulin, a hormone essential for regulating blood sugar and lipids, is normally produced by pancreatic - cells. In many people with diabetes, however, pancreatic cells are not (or no longer) functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through daily insulin injections.

Ecosystems provide numerous benefits, supplying food, clean water and other resources. So, it is vital that ecosystem stability is maintained in the face of disturbances such as drought, heatwaves or nutrient inputs. Nutrient inputs can be particularly problematic in aquatic ecosystems if they lead to algal blooms.

Multidrug-resistant bacteria are found in half of all dog foods made from raw meat, researchers from the University of Zurich have found. Feeding pets a diet of raw meat, also known as a "BARF" diet, is a growing trend. The resistant bacteria in the raw food can be transmitted to the pets - and thus also to humans.

The human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production. A study by anthropologists at the University of Zurich now shows that changes in the brain occurred independent of evolutionary rearrangements of the braincase.

Physicists from UNIGE have discovered a new quantum property: by placing three pairs of photons in a network, it is possible to entangle them and create new ultra-strong correlations. Entanglement is one of the properties specific to quantum particles. When two photons become entangled, for instance, the quantum state of the first will correlate perfectly with the quantum state of the second, even if they are at a distance from one another.

Scientists from the Universities of Geneva and Lyon have discovered which molecule is held responsible for tissue necrosis due to an infarctus, and how to reduce the tissue damage by 30% in mice. Each year, heart attacks kill almost 10 million people in the world, and more than 6 million die from stroke.

Clay minerals suspended in seawater binds sedimentary organic carbon to their mineral surfaces. But the quantity of carbon that is bound and the source of that carbon very much depends on the clay mineral in question. A research team from ETH Zurich and Tongji University have shown this by studying sediments in the South China Sea.

A team of Empa acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can also "swallow" low frequencies very well, as they report Communicatons. The world of crystals offers many interesting properties: crystals can strike electric sparks in disposable lighters, for example, they can produce polarized light and they can scatter bundled X-rays into thousands of individual reflexes that are refracted in all spatial directions.

Molecular dynamics simulations represent an increasingly important cornerstone of modern scientific research, thanks to their unparalleled ability to meticulously describe fundamental aspects of complex systems. It is not a coincidence that nowadays molecular simulations are considered a "virtual microscope" from which admire and examine biological processes, as well as confirm through "computational assays" innovative hypotheses which provide the basis for designing new experiments.

EPFL scientists have developed a deep-learning based motion-capture software that uses multiple camera views to model the movements of a fly in three dimensions. The ultimate aim is to use this knowledge to design fly-like robots. "Just think about what a fly can do," says Professor Pavan Ramdya, whose lab at EPFL's Brain Mind Institute , with the lab of Professor Pascal Fua at EPFL's Institute for Computer Science, led the study.

Researchers at EPFL have created a metallic microdevice in which they can define and tune patterns of superconductivity. Their discovery, which holds great promise for quantum technologies of the future, has just been published in Science. Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies.

Early childhood life in the womb is particularly sensitive to the effects of environmental pollutants. A team from Empa and the University of Vienna has now for the first time been able to show how a pollutant from contaminated food - the environmental estrogen zearalenone - spreads in the womb and is metabolized into harmful metabolites.

In 2002, EPFL awarded the distinction of doctor honoris causa to Michel Mayor, an astronomer at the University of Geneva, for discovering the first exoplanet. This past Tuesday, Mayor, along with colleague Didier Quéloz and the American scientist James Peebles, was awarded the Nobel Prize in Physics.

So far it has not been possible to predict whether a strong quake will probably be followed by a stronger one or not. A new study by researchers from the Swiss Seismological Service at ETH Zurich gives rise to hopes of being able to make predictions in almost real time. Whereas most major earthquakes are not preceded by foreshocks, they are always followed by thousands of aftershocks, whose frequency and magnitude fade over time.

Researchers at EPFL have carried out an in-depth survey of commuter practices in Greater Geneva - the area covering Geneva Canton, the Nyon region and neighboring parts of France. Why do some people cycle instead of taking the bus' Why do others drive rather than traveling by train? Two factors - price and journey time - have long determined how commuters choose to get to work.

A hot, molten Earth would be around 5% larger than its solid counterpart. This is the result of a study led by researchers at the University of Bern. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar System and the understanding of Earth itself.

Michel Mayor and Didier Queloz were awarded the 2019 Nobel Prize in Physics for their discovery of the first exoplanet in 1995. On October 6, 1995, Michel Mayor, Professor at the Observatory of the Faculty of Science of the University of Geneva (UNIGE), Switzerland, and the doctoral candidate Didier Queloz revolutionized the world of astrophysics when they announced the discovery of the first planet located outside our solar system.

To play a piece of music as it was conceived by the composer is a trend. But where can the rare historical instruments be found? The solution would be exact copies of the coveted originals. A team of Empa researchers is analysing such replicas with the aim of reproducing historical trombones with their typical sound.

Increased equality has a positive effect on mothers and fathers. Thanks to greater freedom to strike an individual balance between caring for children and working in paid employment, mothers and fathers today are happier with their lives than parents were 20 or 30 years ago, a study by sociologists at the University of Zurich has shown.

Animals are able to attach simple ratings to complex objects in their environment to guide behavior. For example, humans can easily tell whether they like a wine or not, which will influence their future choices in the wine store. Similarly, animals can tell whether a complex odor is good or bad in order to decide whether to approach or avoid it.
