Neuroscientist Fritjof Helmchen has been awarded a coveted SNSF Advanced Grant worth CHF 2 million to fund his project researching a new theory of memory formation.
The ability to utilize a mere single alternative food source is all it takes for diarrhoea causing Salmonella bacteria to bloom when a gut is already colonized by a closely related strain, according to researchers from ETH Zurich. This coexistence enables the exchange of antibiotic resistance.
"We will rock you": ETH Zurich researchers are developing a gene switch that triggers insulin release in designer cells by playing certain rock and pop songs.
For the first time, researchers combined human and ecological factors to analyse the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases – and for those who would like to eat meat, but don’t want to kill animals.
In autoimmune disorders like multiple sclerosis, the body’s immune system attacks the central nervous system. Immunologist Sarah Mundt wants to figure out why that happens and how to keep autoreactive T cells in check.
The media uproar over wolf attacks on livestock in Switzerland and a bear attack in Italy show how charged the issue of large carnivores and humans coexisting in Europe is. ETH Zurich researcher Paula Mayer has now created a participatory model to help facilitate human-bear coexistence using the example of the Apennine brown bear.
ETH Zurich molecular biologist Mandy Boontanrart is researching gene therapies that could be used to cure two of the most common types of inherited anaemia. She has now developed a promising approach for so-called beta-hemoglobinopathies.
The pathogens that cause urinary tract infections are becoming increasingly resistant to antibiotics. ETH Zurich researchers have now developed a rapid test and a new therapeutic approach using bacteria-infecting viruses known as phages.
A research team from ETH Zurich and the Paul Scherrer Institute PSI together with the Baden Cantonal Hospital and the University Hospital Zurich wants to improve a method for diagnosing breast cancer.
Artificial intelligence is becoming increasingly important in drug discovery. Advances in the use of Big Data, learning algorithms and powerful computers have now enabled researchers at the University of Zurich (UZH) to better understand a serious metabolic disease.
The way the brain regulates pupil size is different from previously thought: fundamentally responsible is the neurotransmitter orexin, as researchers at ETH Zurich have now shown. This discovery could well alter our understanding of consciousness and illnesses such as narcolepsy and Alzheimer’s.
Microbiologists at ETH Zurich have developed computational models that use nutrients and metabolism of plant-associated bacteria to predict how the microbes interact on the surface of leaves and ultimately form the microbiome.
Trichodesmium, a common and ecologically important bacterium, fertilises nutrient-poor regions of the oceans and thereby enables higher life. Crucial to its success is its ability to form aggregates in order to react quickly to changes in its environment. ETH Zurich researchers have shown how the microbes organise themselves in this process.
When Microorganisms decompose organic material in the soil, they actively release CO2 into the atmosphere. This process is called heterotrophic respiration. A novel model shows that these emissions could surge by up to 40 percent by the end of the century – most significantly in the polar regions.
Health data can help to improve the treatment of patients. This is why the University of Zurich, ETH Zurich and the four university hospitals in the city are creating a joint platform for sharing data of this kind. The BioMedical Informatics Platform will be up and running by 2025.
Before DNA in cells can be replicated or repaired, a very specific process must take place. By combining experiment and simulation, researchers led by the University of Zurich were able to decipher this process in detail. Their work also represents a larger change in classical structural biology and our understanding of unstructured proteins.
Our visual perception depends more strongly on the utility of information than previously thought. This has been demonstrated in a series of experiments conducted by researchers at the Neuroscience Center Zurich. Cognitive biases can begin at the retina.
Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria’s metabolism.
Researchers from Basel and Zurich are creating a high-resolution atlas that depicts the development of the human retina. One technique they use is a new method that allows them to visualise more than 50 proteins simultaneously.
Despite approved treatments being available, multiple myeloma remains incurable. But researchers at ETH Zurich and University Hospital Zurich set out to improve treatment outcomes by testing hundreds of existing therapeutics outside the body to predict their effectiveness.
Mouse lemurs give birth to their offspring during the five-month rainy season and build up fat reserves to survive the dry season when food is scarce. But what happens when the rainy season becomes drier and the dry season warmer? Researchers at the German Primate Center - Leibniz Institute for Primate Research and the University of Zurich show that climate changes destabilize mouse lemur populations and increase the risk of extinction.
The MyMi.mobile 2.0 app enables medical students to use their computers or smartphones to conduct microscope examinations of pathology tissue samples. This helps them understand the connections between cell structure and organ dysfunction.
A fuel cell under the skin that converts blood sugar from the body into electrical energy sounds like science fiction. Yet it works perfectly, as an ETH Zurich research team led by Martin Fussenegger, Professor of Biotechnology and Bioengineering, has shown.
By analyzing tumors in unprecedented depth, the Tumor Profiler project represents an important step along the road toward personalized cancer treatments. And the team have already recorded initial successes: in a study focusing on skin cancer, tumors shrank in about one third of patients.
The western chimpanzees of Guinea are threatened by mining activities. Using a novel genetic approach, UZH researchers and an international team have collected information on population size and community structure of the endangered species. These data provide an important baseline to assess the impact of mining.
