How does water seep through porous rock? Investigating this question with a mathematical model was the starting point for Barbara Dembin’s research. The mathematician is generating new insights in what is known as percolation theory.

Hearing-impaired people whose auditory nerve is still intact can often be helped with a cochlear implant. But inserting the implant into the inner ear is not without risks, as facial nerves can be damaged in the process. Empa researchers have developed a novel smart drill that minimizes the risk by automatically shutting off when it comes near nerves.

For the first time, farmers in the Philippines have cultivated Golden Rice on a larger scale and harvested almost 70 tonnes of grains this October. This nearly never-ending story began at ETH Zurich.

A needle and some blood are usually needed for medical diagnostics.

In Switzerland, tire and road wear particles are one of the biggest sources of microplastics released into the environment, yet the chemical compounds contained in those particles – and their effects – remain largely a mystery. To remedy that knowledge gap, scientists at EPFL and two other Swiss research institutes are conducting a study of the toxicity of tire-particle compounds and how readily they’re absorbed by living organisms. The first phase of the study has just been completed.

Despite their differences, cold powder avalanches and hot pyroclastic flows during volcanic eruptions do have a number of things in common, not least their immense destructive power. Completely independently of one another, researchers from both fields have discovered that pulsating flows are responsible for the destructive power of these two natural hazards. A research project supported by the Swiss National Science Foundation is aiming to uncover the origin of this still unknown phenomenon.  

Together with partners in Ethiopia, Rwanda, the Democratic Republic of the Congo and South Africa, ETH Zurich researchers are creating circular economies that use processed organic waste and human excreta as fertilizer or animal feed, resulting in higher crop yields and new jobs.

EPFL researchers have discovered that it is not just molecular density, but also pattern and structural rigidity, that control super-selective binding interactions between nanomaterials and protein surfaces. The breakthrough could help optimize existing approaches to virus prevention and cancer detection.

Gregor Weiss used state-of-the-art microscopy to show how the body prevents bladder infections. He now wants to make this method from basic research usable for the analysis of patient samples – and has received the Lopez-Loreta Prize for it.

Next week the UN intergovernmental negotiating committee (INC) on plastic pollution will meet in Uruguay to develop an international legally binding instrument against plastic pollution. There is concern among scientists that the negotiations will overlook the diversity and complexity of chemicals present in plastics. This would severely undermine the treaty’s effectiveness, according to a new study published in the recent issue of the scientific journal Environmental Science & Technology Letters.

Borrowing from methods used to produce optical fibers, researchers from EPFL and Imperial College have created fiber-based soft robots with advanced motion control that integrate other functionalities, such as electric and optical sensing and targeted delivery of fluids.

Scientists at EPFL, Ludwig Institute of Cancer Research, and CHUV have identified a key protein that helps tumors evade attacks by the immune system, contributing to poor responses to immunotherapy in the clinic.

Researchers from ETH Zurich and the University of Zurich are taking magnetic resonance imaging a step further. With their new method, they can visualise metabolic processes in the body. Their objective is to improve the future diagnosis and treatment of heart disease.

Empa researchers are developing a medical chip in collaboration with the ETH Zurich and the Cantonal Hospital of St. Gallen that will allow statements to be made about the effect of substances on babies in the womb. The Zurich-based ProCare Foundation is funding the project, which was recently launched.

The sweet chestnut and the walnut are an economically important tree species in Europe. It is thanks to the ancient Romans that we find their fruits and wood so widespread today. Scientists at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and the University of Bern have retraced the history of their distribution based on pollen and archaeological evidence.
