Crisis resilience: Swiss companies receive good marks
Crisis resilience: Swiss companies receive good marks
Swiss companies have been more financially resilient through the past years of crisis than their neighbors in Germany and Austria. A high equity ratio, an advanced degree of digitalization and uncomplicated support measures from the state have ensured that Swiss companies are highly resilient to crises.

Excessive fluid consumption: habit or hormonal disorder?
Excessive fluid consumption: habit or hormonal disorder?
People who drink more than three liters of fluid a day may be suffering from a rare hormone deficiency. For many, however, it is just a harmless habit. Failing to differentiate the two correctly can be fatal, so researchers have been investigating what kind of test delivers a reliable diagnosis. In most cases, drinking excessive amounts of fluid, known as polyuria-polydipsia syndrome, either arises out of habit over time or is concomitant with a psychological illness.

A new kind of magnetism
Researchers have detected a new type of magnetism in an artificially produced material. The material becomes ferromagnetic through minimization of the kinetic energy of its electrons. For a magnet to stick to a fridge door, inside of it several physical effects need to work together perfectly. The magnetic moments of its electrons all point in the same direction, even if no external magnetic field forces them to do so.

Is there a physiological explanation behind experiencing glare?
Is there a physiological explanation behind experiencing glare?
Understanding glare is important for improving visual comfort in the built environment. Specific pigments in the eye reduce perception of glare from a blue colored light source, but the pigments do not explain sensitivity to neutrally colored light, scientists show. What is glare? Simply put, glare is visual discomfort often leading to annoyance, fatigue or even headaches.

Printed robots with bones, ligaments, and tendons
Printed robots with bones, ligaments, and tendons
For the first time, researchers have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique. 3D printing is advancing rapidly, and the range of materials that can be used has expanded considerably. While the technology was previously limited to fast-curing plastics, it has now been made suitable for slow-curing plastics as well.

Natural coasts protect against tropical cyclones
Natural coasts protect against tropical cyclones
People living on the in low-lying coastal areas will be at even greater risk from cyclones in the future. Natural ecosystems offer protection, but this protection has decreased in recent years and is expected to continue to decline. This is a finding of a model study by an international team of researchers led by ETH Zurich.

How the COVID-19 virus makes itself more infectious
How the COVID-19 virus makes itself more infectious
Scientists at EPFL have uncovered a cunning strategy that SARS-CoV-2, the virus that causes COVID-19, uses to increase its infectivity. SARS-CoV-2, the novel coronavirus first identified in late 2019, has since spread globally, leading to the COVID-19 pandemic that has affected millions. As countries grapple with its health, social, and economic impacts, scientists and researchers worldwide have been working tirelessly to understand the virus better and develop effective treatments and vaccines.

Better energy efficiency in data processing
Better energy efficiency in data processing
Developed by researchers, the first large-scale in-memory processor using 2D semiconductor materials could substantially cut the ICT sector's energy footprint. As information and communication technologies (ICT) process data, they convert electricity into heat. Already today, the global ICT ecosystem's CO2 footprint rivals that of aviation.

The quagga mussel threatens to upset Lake Geneva ecosystem
The quagga mussel threatens to upset Lake Geneva ecosystem
A team from UNIGE, Eawag and the University of Konstanz has compared the spread of this invasive species in Switzerland and the United States. The result is a better understanding of the threats facing Lake Geneva. Invasive species are one of the main causes of human induced changes to ecosystems. The quagga mussel ( Dreissena rostriformis ) is one of them.

Diverse forests hold huge carbon potential, as long as we cut emissions
Diverse forests hold huge carbon potential, as long as we cut emissions
New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. Research results published in the journal, external page Nature call_made , show that realistic global forest carbon potential is approximately 226 Gigatonnes (Gt) of carbon.

The risk of thrombosis decreases rapidly when hormonal contraception is discontinued.
The risk of thrombosis decreases rapidly when hormonal contraception is discontinued.
A team of researchers has shown that the risk of thrombosis largely disappears within two to four weeks of stopping the use of hormonal contraceptives. The use of the contraceptive pill and other combined hormonal contraceptives (CHC) triples the risk of blood clots. However, a prospective study by the University of Geneva and the University Hospitals of Geneva (HUG), published in the journal Blood , shows that this risk largely disappears within two to four weeks of stopping use of these contraceptives.

Poison dart frogs: Personality determines reproductive strategies
Unlike their relatives, individuals of the poison frog Allobates femoralis are not poisonous but are captivating due to their different behavioral profiles: They successfully reproduce with different strategies depending on whether they are bold, aggressive or explorative. In addition, certain character traits are already present in this species at the tadpole stage.

Structural disadvantages in addiction support
Addiction support in Switzerland has grown historically and is the responsibility of the cantons and municipalities. The structures and services are correspondingly fragmented. People affected by addiction cannot always access the same help services. The place of residence and canton influence the services on offer.
