Nanoplastics - an underestimated problem?
Nanoplastics - an underestimated problem?
The images leave no one cold: giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants - the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected in virtually all ecosystems.

Stress and Mental Health Problems During First COVID-19-Lockdown
One-third of children and adolescents experienced mental health problems during the first COVID-19 lockdown in Switzerland. Parents and young adults also perceived considerable stress, yet the perceived stresses differed from those of children and adolescents, the first Switzerland-wide representative study by the University of Zurich and La Source School of Nursing Lausanne has shown.

COVID-19 test detects antibodies in hundreds of tiny blood samples
Antibody testing can be a powerful tool for tracking the spread of SARS-CoV2 infections, the virus responsible for the COVID-19 pandemic. A group of scientists from EPFL, UNIGE and HUG have now developed a reliable and cheap antibody test that can analyze more than 1,000 samples at once and requires a small drop of blood, such as that from a finger prick.

USI develops innovative system for better credit card fraud detection
USI develops innovative system for better credit card fraud detection
The use of credit cards and other cashless or digital payment methods has become the norm for consumers all over the globe, and the strong surge of online buying during the pandemic has further boosted this decade-long trend. However, behind the convenience of 'click and pay' there are also risks, such as fraud and related losses, which are mostly borne by the card companies.

A physics perspective on wound healing
A physics perspective on wound healing
Scientists from the University of Geneva and UZH have used a statistical physics approach to identify the lengthscales of key intercellular interactions which govern tissue healing. In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells?

New hydropower dam design tested at EPFL
New hydropower dam design tested at EPFL
A team of EPFL engineers has completed proof-of-concept tests for the new Massongex-Bex-Rh˘ne hydropower dam. The tests, involving both a physical scale model and computer simulations, enabled the engineers to fine-tune their design. Engineers at EPFL's Platform of Hydraulic Constructions (PL-LCH) in Lausanne have just finished testing the design for the new Massongex-Bex-Rh˘ne (MBR) hydropower dam.

How diet controls RNA maturation
How diet controls RNA maturation
Two UNIGE teams have discovered a new mechanism for regulating RNA maturation that depends on diet. Particularly sensitive to chemical modifications, messenger RNAs (mRNAs) are molecules responsible for transmitting the information encoded in our genome, allowing for the synthesis of proteins, which are necessary for the functioning of our cells.

A bacterial toxin facilitating chronic infection
A bacterial toxin facilitating chronic infection
Some pathogens persist in the body causing chronic infections. Researchers at the University of Basel have now discovered a mechanism of highly selective targeting of host proteins by a bacterial toxin that is critical for the bacteria to establish chronic infection. The study recently published in PNAS provides new insights into the activity and function of bacterial toxins.

The shape of light changes our vision
The shape of light changes our vision
Scientists at the UNIGE have shown that the response of the retina to light depends not only on the intensity of the light perceived by the eye, but also on its temporal shape and the order in which the colours are organized. Vision is a complex process that has been successfully deciphered by many disciplines -physics, biochemistry, physiology, neurology, etc.-: The retina captures light, the optic nerve transmits electrical impulses to the brain, which ultimately generates the perception of an image.

Uncertainty of future Southern Ocean CO2 uptake cut in half
Uncertainty of future Southern Ocean CO2 uptake cut in half
The Southern Ocean dominates the oceanic uptake of human-made CO2. But how much carbon dioxide can it actually absorb in the future? This long-standing question remained unresolved as projections of different generation of climate models repeatedly showed a wide range of future Southern Ocean CO2 sink estimates.

Global glacier retreat has accelerated
Global glacier retreat has accelerated
An international research team including scientists from ETH Zurich has shown that almost all the world's glaciers are becoming thinner and losing mass' and that these changes are picking up pace. The team's analysis is the most comprehensive and accurate of its kind to date. Glaciers are a sensitive indicator of climate change - and one that can be easily observed.

The First Comprehensive Single-Cell Atlas of Human Teeth
The First Comprehensive Single-Cell Atlas of Human Teeth
Researchers at the University Zurich have mapped the first complete atlas of single cells that make up the human teeth. Their research shows that the composition of human dental pulp and periodontium vary greatly. Their findings open up new avenues for cell-based dental therapeutic approaches. During the last 30 years, medical and dental research has attracted a large number of scientists and practitioners working on aspects of high medical relevance that involve a combination of genetic and tissue regeneration approaches.

Theory and experiments to understand a contact between two filaments
Theory and experiments to understand a contact between two filaments
Mechanical engineers and mathematicians at EPFL have joined forces to gain a better understanding of the geometry and mechanics of two filaments in contact - as in the cases of knots and woven fabrics. Pedro Reis, head of EPFL's Flexible Structures Laboratory, and John Maddocks, head of EPFL's Laboratory for Computation and Visualization in Mathematics and Mechanics, have something in common: a fascination with ropes and knots.

Quantum steering for more precise measurements
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. In quantum information, the fictitious agents Alice and Bob are often used to illustrate complex communication tasks.

Eliminating resistant bacteria with nanoparticles
Novel nanoparticles developed by researchers at ETH Zurich and Empa detect multi-resistant bacteria hiding in body cells and kill them. The scientists' goal is to develop an antibacterial agent that is effective where conventional antibiotics remain ineffective. In the arms race "mankind against bacteria", bacteria are currently ahead of us.
