Tiny plastic particles are found everywhere
Tiny plastic particles are found everywhere
Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed. This is one finding of a recent study involving researchers from the University of Basel. It's not the first study on microplastics in Antarctica that researchers from the University of Basel and the Alfred-Wegener Institute (AWI) have conducted.

Protecting art and passwords with biochemistry
Protecting art and passwords with biochemistry
A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers. Security experts fear Q-Day, the day when quantum computers become so powerful that they can crack today's passwords. Some experts estimate that this day will come within the next ten years.

A friendly pat on the back can improve performance in basketball
A friendly pat on the back can improve performance in basketball
A free throw in basketball will have every eye glued to one person. It's an intensely stressful situation. A research team led by the University of Basel studied whether a friendly tap on the shoulder increases the odds of making a shot. In difficult situations, physical touch like a hug or a pat on the back can reduce stress.

Global warming is sinking meteorites
Global warming is sinking meteorites
More than 300,000 meteorites lie on the Antarctic ice. They contain an unprecedented wealth of information about our solar system. With every tenth of a degree of global warming, thousands of meteorites sink. Researchers from WSL and ETH recommend that their collection be promoted. The Antarctic holds a valuable treasure of around 300,000 meteorites lying on the surface of the ice.

Largest 3D map of the universe ever made
Largest 3D map of the universe ever made
The first results from the Dark Energy Spectroscopic Instrument, or DESI, project, with significant contributions from EPFL astrophysicists, has mapped galaxies and quasars with unprecedented detail measuring how fast the universe expanded over 11 billion years. The Dark Energy Spectroscopic Instrument project, an international collaboration of more than 900 researchers from over 70 institutions around the world including EPFL, has released its first results - a map of galaxies and quasars with unprecedented detail, creating the largest 3D map of the universe ever made.

CHEOPS detects a ’’rainbow’’ on an exoplanet
New observations from the space telescope point to the existence of a 'glory' in the atmosphere of WASP-76b, a luminous phenomenon like a rainbow. The CHEOPS space telescope, whose scientific operations centre is based at the University of Geneva , is providing new information on the mysterious exoplanet WASP-76b.

Transformative potential of decentralization
Transformative potential of decentralization
Researchers from EPFL and HES-SO Valais Wallis have published a study outlining a path to a more sustainable energy future for Switzerland. The study emphasizes the importance of local energy solutions, and the role of decentralized systems for community empowerment. A pivotal finding of the study, published in Energies , is the integration of decentralized photovoltaic (PV) systems into the Swiss energy grid; this could reduce annual system costs by 10% and elevate self-consumption rates to 68%.

Cystic fibrosis: why infections persist despite therapy
A team from the University of Geneva discovered that treatment for cystic fibrosis does not eliminate the docking stations of bacteria responsible for respiratory infections. Cystic fibrosis is a genetic and hereditary disease affecting specific cells - epithelial cells - lining certain organs, including the respiratory epithelium in our lungs (inset).

Airy cellulose from a 3D printer
Airy cellulose from a 3D printer
Ultra-light, thermally insulating and biodegradable: Cellulose-based aerogels are versatile. researchers have succeeded in 3D printing the natural material into complex shapes that could one day serve as precision insulation in microelectronics or as personalized medical implants. At first glance, biodegradable materials, inks for 3D printing and aerogels don't seem to have much in common.

Impacts of invasive species transcend ecosystem boundaries
Impacts of invasive species transcend ecosystem boundaries
Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade and that three mechanisms are primarily responsible for this.

Liberalization of medical marijuana and mental health in the USA
Liberalization of medical marijuana and mental health in the USA
The approval of marijuana for medical use has had little effect on the mental health of the general population in the US. But legalization for therapeutic purposes does benefit those for whom it is intended. This is the conclusion of a study by researchers at the University of Basel. In the US, access to marijuana has been facilitated in most states since the mid-1990s - whether through medical clearance or through decriminalization of recreational use.

Nanodevices can produce energy from evaporating tap or seawater
Nanodevices can produce energy from evaporating tap or seawater
Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential. Evaporation is a natural process so ubiquitous that most of us take it for granted.

New Discovery Unravels Malaria Invasion Mechanism
New Discovery Unravels Malaria Invasion Mechanism
A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study, led by the Swiss Tropical and Public Health Institute (Swiss TPH) and Griffith University's Institute for Glycomics, reveals the role of a sugar called sialic acid in this invasion process.

Machine learning enables viability of vertical-axis wind turbines
Machine learning enables viability of vertical-axis wind turbines
Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind. If you imagine an industrial wind turbine, you likely picture the windmill design, technically known as a horizontal-axis wind turbine (HAWT).

How the brain senses body position and movement
How the brain senses body position and movement
Researchers at EPFL use neural networks to study proprioception, the sense the brain uses to "know" the body's movement and position. How does your brain know the position and movement of your different body parts? The sense is known as proprioception, and it is something like a "sixth sense", allowing us to move freely without constantly watching our limbs.

Corn reduces arsenic toxicity in soil
Corn reduces arsenic toxicity in soil
When crops grow in arsenic-contaminated soil, this toxic element accumulates in the food chain. A study involving the University of Basel has now discovered a mechanism used by corn plants to reduce arsenic uptake: the key factor is a special substance released into the soil by the roots. Arsenic is a toxic metalloid of natural origin.
