Cancer cells hijack the 3D structure of DNA
Cancer cells hijack the 3D structure of DNA
Scientists have used a novel algorithmic approach on cancer cells to understand how changes in histone marks (H3K27ac) induce repositioning of chromatin regions in the cell nucleus, and described how modifications of local contacts between regulatory elements (enhancers and promoters) influence oncogene expression.

Regular virus tests can curb infection rates
Regular virus tests can curb infection rates
Since February 2021, the canton of Grisons is using saliva-based PCR mass testing within its mobile workforce as a potential means to contain the COVID-19 pandemic and reduce infection rates. Empa researchers are now leading the analysis of data from the first eight weeks of the testing regime. They observed a reduction in the incidence rate between 20 and 50%, depending on the business sector, and a noticeable reduction in the test positivity rate among those who were regularly tested.

The African Wild Dog: An Ambassador for the World's Largest Nature Reserve
The African Wild Dog: An Ambassador for the World’s Largest Nature Reserve
The world's largest nature conservation area lies in southern Africa, comprising 520,000 square kilometers that span five countries. A study has now shown that the critically endangered African wild dog mostly remains within the Kavango-Zambezi Transfrontier Conservation Area (KAZA) during its long periods of migration.

Flooding might triple in the mountains of Asia
Flooding might triple in the mountains of Asia
A team of Swiss and international climate scientists has shown that the risk of glacial lake outburst floods in the Himalayan region and the Tibetan plateau could triple in the coming decades. The "Third Pole" of the Earth, the high mountain ranges of Asia, bears the largest number of glaciers outside the polar regions.

Biomarker Detects Severe COVID-19 Early On
Severe cases of COVID-19 can now be detected at an early stage. Researchers at the University of Zurich have identified the first biomarker that can reliably predict which patients will develop severe symptoms. This can help to improve the treatment of severe cases of COVID-19. Most people who are infected with SARS-CoV-2 develop no or only mild symptoms.

Cell cytoskeleton as target for new active agents
Cell cytoskeleton as target for new active agents
Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before.

Exercise aids the cognitive development of children born preterm
Exercise aids the cognitive development of children born preterm
A premature start in life can cause problems even into teenage years. A study by the University of Basel and the University Children's Hospital Basel (UKBB) indicates that training motor skills in these children helps even when they are older. Children that are born before the 37 th week of pregnancy remain under close medical supervision while they are young.

Defective Epithelial Barriers Linked to Two Billion Chronic Diseases
Defective Epithelial Barriers Linked to Two Billion Chronic Diseases
Humans are exposed to a variety of toxins and chemicals every day. According to the epithelial barrier hypothesis, exposure to many of these substances damages the epithelium, the thin layer of cells that covers the surface of our skin, lungs and intestine. Defective epithelial barriers have been linked to a rise in almost two billion allergic, autoimmune, neurodegenerative and psychiatric diseases.

How mitochondria make the cut
How mitochondria make the cut
With the help of their custom-built super-resolution microscope, EPFL biophysicists have discovered where and why mitochondria divide, putting to rest controversy about the underlying molecular machinery of mitochondrial fission. Mitochondria either split in half or cut off their ends to self-regulate.

A material-keyboard made of graphene
A material-keyboard made of graphene
Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.

Climate action potential in waste incineration plants
The climate action potential of carbon capture during the processing of biomass feedstock is considerable, ETH Zurich researchers have calculated. If this potential is to be fully exploited in practice, however, there are challenges to overcome.   Over the coming decades, our economy and society will need to dramatically reduce greenhouse gas emissions as called for in the Paris Agreement.

Northern Red Sea corals pass heat stress test with flying colors
Northern Red Sea corals pass heat stress test with flying colors
Scientists are beginning to understand why corals in the Gulf of Aqaba, along with their symbiotic algae and bacteria, resist higher temperatures particularly well. Even under the most optimistic scenarios, most of the coral reef ecosystems on our planet - whether in Australia, the Maldives or the Caribbean - will have disappeared or be in very bad shape by the end of this century.

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
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?

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.
