When mental health moves through social media
When mental health moves through social media
Can a Tweet or a post on Instagram tell us something about our mental health? How meaningful is the relationship between well-being and the use of these platforms? To answer these questions, Marta Fadda, a researcher in bioethics at UniversitÓ della Svizzera italiana, Oliver GrŘbner, a health geographer, and Marcus Wolf, a psychologist, at the University of Zurich conducted a series of studies to demonstrate the usefulness of social platforms for mental health research.

Optimising nitrogen removal from wastewater
Optimising nitrogen removal from wastewater
Too much nitrogen continues to enter many water bodies, negatively impacting ecosystems and human health. The anammox process co-developed by Eawag can make an important contribution to reducing outputs from wastewater treatment plants and also saves energy and resources. It has now been further optimised by researchers at Eawag.

James Webb Space Telescope identifies origins of icy building blocks of life
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discovered the deepest and coldest ice ever detected in such a molecular cloud.

Private patients receive treatment for heart conditions more often than those with basic health insurance
Private patients receive treatment for heart conditions more often than those with basic health insurance
Patients in Switzerland with supplementary private health insurance are more likely to undergo cardiac procedures than those with only basic health insurance. This has been demonstrated in a study by researchers from the University of Basel and the Cantonal Hospital of Aarau. Switzerland has one of the most expensive healthcare systems in the world.

Tracing the flow of water with DNA
Tracing the flow of water with DNA
Environmental DNA analysis of microbial communities can help us understand how a particular region's water cycle works. Basel hydrogeologist Oliver Schilling recently used this method to examine the water cycle on Mount Fuji. His results have implications for Switzerland as well. Where does the water come from that provides drinking water to people in a particular region? What feeds these sources and how long does it take for groundwater to make its way back up to the surface? This hydrological cycle is a complex interplay of various factors.

Why rivers matter for the global carbon cycle
Why rivers matter for the global carbon cycle
In a new journal article, EPFL professor Tom Battin reviews our current understanding of carbon fluxes in the world's river networks. He demonstrates their central role in the global carbon cycle and argues for the creation of a global River Observation System. Until recently, our understanding of the global carbon cycle was largely limited to the world's oceans and terrestrial ecosystems.

Tumultuous migration on the edge of the Hot Neptune Desert
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.

From molecules to organisms
From molecules to organisms
How did life on Earth first emerge? And how was it able to prosper and evolve? researchers are involved in the quest to find answers to these fundamental questions. Since time immemorial, humanity has pondered the question of how life on Earth first began. Ancient cultures declared the creation of the world and the origin of life to be the work of gods and other divine beings.

Protecting ecosystems with ecological theory
Protecting ecosystems with ecological theory
Ecosystems respond sometimes very differently to human impacts. However, it is still poorly understood what causes these differences. A team of researchers from Eawag and WSL is now proposing an integrative approach based on four fundamental processes shaping biodiversity on land and in water. The approach provides guidance for how biodiversity in blue (water) and green (land) ecosystems can be better protected.

Improving perovskite solar cell resistance to degradation
Improving perovskite solar cell resistance to degradation
Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.

Deflecting lightning with a laser lightning rod
Deflecting lightning with a laser lightning rod
A European consortium led by UNIGE, Úcole Polytechnique (Paris), EPFL, hes-so and TRUMPF has managed to guide lightning using a high-power laser installed at the top of Mount Sńntis 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.

A precision arm for miniature robots
A precision arm for miniature robots
Until now, microscopic robotic systems have had to make do without arms. Now researchers at ETH Zurich have developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap particles. We are all familiar with robots equipped with moving arms.

Drug combo breaks down cancer resistance to immunotherapy
By combining a checkpoint inhibitor with a new immunocytokine, scientists at EPFL, Ludwig Institute for Cancer Research, CHUV and Roche have made a breakthrough in fighting against immunotherapy-resistant cancers. Immunotherapy is a way of treating cancer by reprogramming the patient's immune system to attack their tumor.

Financial incentives for vaccination do not have unintended negative consequences
Financial incentives for vaccination do not have unintended negative consequences
Contrary to warnings in the academic literature and public debate, modest financial incentives for vaccination can be used without fear of serious unintended consequences. This is the result of a scientific study, published in "Nature", conducted by the University of Zurich, Lund University and UnisantÚ.

Placebo reduces feelings of guilt
Guilt is an uncomfortable feeling and can be burdensome. Researchers at the University of Basel have shown that placebos can help reduce feelings of guilt, even when the placebo is administered openly. People don't always behave impeccably in relationship to others. When we notice that this has inadvertently caused harm, we often feel guilty.

Integrated photonic circuits could help close the 'terahertz gap'
Integrated photonic circuits could help close the 'terahertz gap'
Researchers have collaborated with those at Harvard and ETH Zurich on a new thin-film circuit that, when connected to a laser beam, produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics and telecommunications. Researchers led by Cristina Benea-Chelmus in the Laboratory of Hybrid Photonics ( HYLAB ) in EPFL's School of Engineering have taken a big step toward successfully exploiting the so-called terahertz gap, which lies between about 300-30,000 gigahertz (0.3 to 30 THz) on the electromagnetic spectrum.

How grasses avoid inbreeding
How grasses avoid inbreeding
Researchers have been able to show which genes inhibit self-fertilisation in grasses. Plant scientists can now use this mechanism in a more targeted way to breed new varieties of forage grasses as well as rice or barley. 'This breakthrough was enabled by technological advances in genome analysis. It's only in recent years that these have made it possible to efficiently sequence the entire genome of an individual organism.' Studer has devoted over 15 years to this subject, together with collaborators from Denmark, Wales and the USA.

New oxytocin sensor: novel applications in psychiatry
New oxytocin sensor: novel applications in psychiatry
A recent study from the University of Lausanne unveils a new method to measure oxytocin in the brain using a bioengineered fluorescent sensor. The applications of this sensor are novel and promising for psychiatry . Oxytocin Oxytocin is a neuropeptide produced by the hypothalamus, an area at the base of the brain that regulates many of the body's physiological processes as well as instinctive brain behaviors.
