Winners and losers of energy transition
Winners and losers of energy transition
Accounting for multiple social aims other than costs is critical for transitioning from fossil fuels to renewable electricity. A new study by UNIGE proposes a viable compromise. The European Green Deal aims to drastically reduce greenhouse gas emissions in the electricity sector, which could have substantial economic and social impacts across Central European regions.

Scientist gains fresh insight into the origins of earthquakes
The speed and intensity with which seismic waves propagate after an earthquake depend mainly on forces occurring deep inside the rocks along a fault line, according to a study by EPFL scientist François Passelègue. His sophisticated models are giving us fresh insight into the factors that can trigger an earthquake.  Sometimes barely noticeable, and at other times devasting, earthquakes are a major geological phenomenon which provide a stark reminder that our planet is constantly evolving.

Mental accounting is impacting sustainable behavior
Mental accounting is impacting sustainable behavior
UNIGE psychologists are analysing the way our minds plan the use of resources so that interventions can be developed to reduce excessive energy consumption and carbon emissions. Mental accounting is a concept that describes the mental processes we employ to organise our resource use. Human beings tend to create separate mental budget compartments where specific acts of consumption and payments are linked.

Using electric current to stabilize low-permeability soils
Using electric current to stabilize low-permeability soils
Scientists have developed a new approach to stabilizing clay soils. The method involves using a battery-like system to apply electric current to carbonate and calcium ions in order to promote soil consolidation. Their findings were published yesterday in Scientific Reports. According to figures released by the UN yesterday, natural disasters have killed more than 1.2 million people since 2000 and cost nearly $ 3 trillion.These pressing threats bring into sharp focus the need for new answers to the problem of soil stabilization.

Well-formed disorder for versatile light technologies
Researchers at ETH have managed to make an efficient material for broadband frequency doubling of light using microspheres made of disordered nanocrystals. The crucial idea for the method arose during a coffee break. In the future, the new approach could be used in lasers and other light technologies.

Mechanical forces of biofilms could play role in infections
Studying bacterial biofilms, EPFL scientists have discovered that mechanical forces within them are sufficient to deform the soft material they grow on, e.g. biological tissues, suggesting a -mechanical- mode of bacterial infection. The vast majority of bacteria in the world live on surfaces by forming structures called -biofilms-.

HIV epidemic: Successful use of self-tests in rural Africa
HIV epidemic: Successful use of self-tests in rural Africa
Despite significant progress in prevention and therapy, millions of people still get infected with HIV every year. The main burden of HIV/AIDS falls on Africa. To contain the epidemic, innovative methods are needed to enable early diagnosis of all those affected. A Basel research group has now been able to significantly improve the success of "door-to-door" testing campaigns thanks to HIV self-tests.

Bacteria in sediment continue to show effects of over-fertilisation
Bacteria in sediment continue to show effects of over-fertilisation
Whether a lake was once polluted with excess nutrients is reflected even decades later in the community of bacteria living on these nutrients in the sediment. However, there is still surprisingly little research into how microbes in the sediment cooperate. From a global perspective, lake sediments are important carbon sinks.

Modeling eternity in the rock laboratory
Modeling eternity in the rock laboratory
Cement is one of the key materials for the safe storage of radioactive waste. What is needed is an almost infinite durability of the containers. Empa researchers are therefore analyzing material systems that can handle this task. Exploratory tunnel in the Mont Terri international rock laboratory. Since 1996, rock formations that could play a role in the storage of radioactive waste have been investigated here.

Miniature organs shed light on intestinal regeneration
Miniature organs shed light on intestinal regeneration
In a study, researchers from Basel unraveled mechanisms orchestrating organoid formation and intestinal regeneration. Using a unique image-based screening approach, the researchers identified a compound that improves intestinal regeneration in mice. The last decade has seen a boom in the field of organoids, miniature organs grown from stem cells in vitro.

Vaporised metal in the air of an exoplanet
An international team of researchers led by the National Centre of Competence in Research PlanetS of the University of Bern and the University of Geneva studied the atmosphere of the ultra-hot exoplanet WASP-121b. In it, they found a number of gaseous metals. The results are a next step in the search for potentially habitable worlds.

Intestinal regeneration: lessons from organoid research
Intestinal regeneration: lessons from organoid research
Intestinal organoids recapitulate not only the structure of intestinal epithelium but also its ability to regenerate following damage. Using this research tool, the group of Prisca Liberali unraveled mechanisms orchestrating organoid formation and intestinal regeneration with a unique image-based screening approach.

Making disorder for an ideal battery
Making disorder for an ideal battery
Manufacturing safer, more powerful batteries that use geopolitically stable resources requires solid electrolytes and replacing lithium with sodium. A chemical solution is now being offered to battery developers. The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks.

HIV Self-Tests: Key Contributor to Ending HIV Epidemic in Sub-Saharan Africa
HIV Self-Tests: Key Contributor to Ending HIV Epidemic in Sub-Saharan Africa
HIV continues to be a major global health issue, with 1.7 million new infections in 2019 alone. In Africa, a part of the world that shoulders most of the HIV burden, home-based HIV testing is a promising solution to address the HIV epidemic. In two recent studies published in The Lancet HIV and the Journal of International AIDS Society, Swiss TPH and partners found that HIV self-tests during home-based testing campaigns significantly increased people's awareness of their HIV status, particularly in the most remote regions.

Artificial lung helps investigate how COVID-19 causes blood clots
Scientists at EPFL are using technology to better understand how coronavirus causes blood clots in some patients. They have developed a simplified model of a lung that lets them observe, for the first time, how the virus attacks the cells lining blood vessels. COVID-19 sometimes causes blood clots, although the exact incidence remains a mystery.

Job satisfaction decreases with digitisation
Job satisfaction decreases with digitisation
This year's Swiss HR Barometer combines two major trends: digitisation, and an aging society. Almost 40 percent of those surveyed can imagine working beyond retirement age. Job satisfaction decreases as digitisation of an employee's tasks increases. Digitisation and electronic monitoring The respondents believed that employers in Switzerland are relatively open to new technologies: more than 74 percent of employees indicated that their employer is willing to use digital solutions.

Lego-like assembly of zeolitic membranes improves carbon capture
EPFL chemical engineers have developed a new way to manufacture zeolitic membranes, state-of-the-art materials used for gas separation in harsh conditions. Zeolites are porous minerals that occur both naturally but also are being synthesized artificially. Because they are stable and durable, zeolites are used for chemical catalysis, purification of gases and liquids, and even in medical applications such as drug delivery and blood-clotting powders, e.g. the QuickClot trauma bandages used in the US military.
