The role of surface tension in biological symmetry
The role of surface tension in biological symmetry
Researchers have discovered that symmetry in the human body is influenced by surface tension, the same mechanical phenomenon that allows lightweight insects to walk on water. A paper discussing this surprising finding, which is akin to a form of natural self-correction, has been published. In vertebrates, the arms, legs, fins and wings are neatly aligned on either side of the torso.

Glowing glass droplets on the ISS
Glowing glass droplets on the ISS
Together with researchers from Ulm and Neuchâtel, Empa will soon be studying material samples on the ISS. The material in question are super-hard and corrosion-resistant alloys of palladium, nickel, copper and phosphorus - also known as "metallic glasses". A high-tech company from La Chaux-de-Fonds, which produces materials for the watch industry, is also involved.

Imaging chemical kinetics at liquid-liquid interfaces
Imaging chemical kinetics at liquid-liquid interfaces
Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of dynamics on the sub-millisecond timescale, which is very difficult to do with current applications.

Urine treatment: from trial and error to exciting innovation
Urine treatment: from trial and error to exciting innovation
What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine.

A solution to perovskite solar cell scalability problems
A solution to perovskite solar cell scalability problems
Scientists at EPFL have found a way to overcome power loss and the manufacturing complexity of scaling up perovskite solar cells. Perovskites are hybrid materials made from metal halides and organic compounds. They have attracted a lot of interest in the field of solar energy because of their light-harvesting capacities combined with a low cost of manufacturing, making them prime candidates for overtake the market from their silicon counterparts.

Legionellosis Cases Continue to Increase in Switzerland
Legionellosis Cases Continue to Increase in Switzerland
The number of legionellosis cases in Switzerland has increased five-fold over the past 20 years. A study by the Swiss Tropical and Public Health Institute (Swiss TPH) published today in the International Journal of Hygiene and Environmental Health analysed case numbers from 2000 to 2020 and determined the potential impact of the COVID-19 pandemic on reporting.

Bioassays evaluate ozonation and post-treatment of wastewater
Bioassays evaluate ozonation and post-treatment of wastewater
Through wastewater, rivers and lakes are polluted with numerous micropollutants which originate from care products and pharmaceuticals, among other things. The Waters Protection Act therefore aims to expand Swiss wastewater treatment plants (WWTP) with the addition of a further treatment step. In pilot tests, two processes have proven particularly successful in the removal of trace substances: ozonation and treatment with activated carbon.

Improving the efficiency of tandem solar cells
Improving the efficiency of tandem solar cells
Scientists in Neuchâtel have developed a tandem solar cell that can deliver a certified efficiency of 29. This achievement was made possible by combining a perovskite solar cell with a textured silicon solar cell. Solar cells made of silicon are used widely but have limited power-conversion yields. These yields will likely top out at around 27% in the foreseeable future, owing to fundamental thermodynamic limitations.

A new mutation behind synucleinopathies
A new mutation behind synucleinopathies
Scientists at EPFL have carried out an extensive study of a newly discovered mutation that can uncover new insights into the molecular basis of pathology formation in a family of disorders that includes Lewy body dementia and Parkinson's disease. Parkinson's disease and Lewy body dementia belong to a family of neurodegenerative disorders called synucleinopathies because they are caused by the pathological accumulation of protein alpha-synuclein into structures called Lewy bodies and Lewy neurites in the brain.

Breakthroughs at IOR in the search for anti-metastatic therapies
Breakthroughs at IOR in the search for anti-metastatic therapies
The Molecular Oncology research group at USI has identified, through the use of bioinformatics and artificial intelligence, a new way to selectively identify and kill a specific type of cells involved in metastasis dissemination. The problem Metastasis, the spreading of tumor cells from a primary site to their progressive outgrowth at a distant organ, is ultimately what kills almost 90% patients with cancer.

Climate warming alters glacier-fed stream ecosystems worldwide
Climate warming alters glacier-fed stream ecosystems worldwide
According to two recent studies carried out as part of the Vanishing Glaciers Project, the ecosystems of glacier-fed streams are undergoing profound change around the world. That could have major repercussions on the food chain and the natural carbon cycle. The ecosystems of glacier-fed streams have survived nutrient-poor and harsh environmental conditions over the course of thousands of years, yet they are now being transformed by climate change at unprecedented pace.

Countless chemical substances, including fertilisers and pesticides but also pharmaceutical substances and industrial products, leak into groundwater, lakes and rivers. "We want to know what the impact of these chemicals is on aquatic species, and whether they are toxic or not," says Marco Baity-Jesi, Head of the Eawag Data Science Group.

Palmitoylation, a new target for anti-cancer drugs
By developing a tool to visualize the membrane association and activation status of normal and oncogenic proteins, scientists at the University of Geneva have established the basis for innovative drug discovery. Peripheral membrane proteins have the particularity of temporarily binding to cell membranes, a necessary step for them to be able to fulfil their biological function.

Targeting ’anti-tumor’ genes to provide better treatment for leukemia
Scientists discuss the possibility of offering personalized treatment for chronic lymphocytic leukemia by regulating the expression of a gene known for its "anti-tumorous" properties. Chronic lymphocytic leukemia (CLL) is one of the most common blood cancers in adults. The disease originates in B cells - the part of the immune system that produces antibodies - and then evolves slowly, typically affecting older people.

Revolutionary images of the birth of crystals
Revolutionary images of the birth of crystals
A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now. At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology.

Multiple treatments to slow age-related muscle wasting
Multiple treatments to slow age-related muscle wasting
Everyone wants to stay fit and healthy as they grow old. But as we age, our body degrades, our muscles shrink and strength declines. Some older people suffer from excessive muscle loss, a condition known as sarcopenia. University of Basel researchers show that a combination therapy could delay the onset of sarcopenia.

Structural insights into the assembly of cilia
Cilia, the little "hairs" attached to almost all cells of the human body, play a role in various cellular functions and cause diseases called ciliopathies when they are defective. Researchers from the group of Patrick Matthias and the FMI Structural Biology platform determined the structure, at near atomic resolution, of a protein complex that plays an essential role in the assembly of cilia - and causes ciliopathies when it is mutated.

No glacial fertilization effect in the Antarctic Ocean
No glacial fertilization effect in the Antarctic Ocean
Can iron-rich dust fertilize the ocean, stimulate algae growth there, and thereby capture carbon dioxide from the atmosphere? An international research team involving the University of Bern and led by the University of Bonn used deep-sea sediment cores from the Scotia Sea to investigate whether this hypothetical greenhouse gas sink had an effect during ice ages.
