PSI scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the protein is responsible for relaying the optical signal from the eye to the brain. If a genetic disorder disrupts the molecular function in a person, they will go blind. Scientists have deciphered the protein’s three-dimensional structure, preparing the way for innovative medical treatments. The study is published in the scientific journal Nature Structural & Molecular Biology.

How much does a country's vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more "crossover" models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. Empa researchers analyze databases using deep learning methods - and can make precise statements: In which region of the country do the fattest cars drive? What can car buyers do to reduce CO₂ consumption?

Shared e-scooters and e-bikes transport the image of a climate-friendly mobility solution. ETH researchers have now shown that shared micromobility solutions in Zurich emit more CO₂ emissions than the alternatives they replace.

Thanks to the high-power electron microscopes at the Dubochet Center for Imaging (DCI), EPFL scientists were able to observe the configuration of the Omicron variant’s spike protein at a near-atomic scale. This should provide fresh insight into the mechanisms the variant uses to evade vaccines and antibodies.

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics – circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes in electron microscopy.

Quantum effects in superconductors could give semiconductor technology a new twist. Researchers at the Paul Scherrer Institute PSI and Cornell University in New York State have identified a composite material that could integrate quantum devices into semiconductor technology, making electronic components significantly more powerful. They publish their findings today in the journal Science Advances.

In a unique collaboration with ECAL/University of Art and Design Lausanne, EPFL researchers have developed an algorithm designed to generate some of the world’s first Chinese typefaces, using machine learning.

Like bridges and tall buildings, large mountains are constantly vibrating, excited by seismic energy form the Earth. An international team of researchers has now been able to measure the resonant swaying of the Matterhorn and make its motion visible using computer simulations.

Two EPFL research groups teamed up to develop a machine-learning program that can be connected to a human brain and used to command a robot. The program adjusts the robot’s movements based on electrical signals from the brain. The hope is that with this invention, tetraplegic patients will be able to carry out more day-to-day activities on their own.

The launch of the James Webb Space Telescope is set to take place in the coming days. For ETH Zurich physicist Adrian Glauser, who was involved in two unspectacular but vital contributions to this ambitious project, it will bring to an end a long period of anxious anticipation.

Intelligent packaging with sensors that monitor goods, such as vegetables, on long transport routes is a trend for the future. Yet printed and disposable electronics also cause problems: Metals in printing inks are expensive – and disposing of them in an environmentally sound manner is costly and exacerbates the problem of electronic waste. A new solution from Empa researchers aims to remedy this.

Noise barriers or improved wheel systems and brakes that are less noisy are not the only ways to reduce railway noise for close-by residents. An inconspicuous component under the tracks is a source of hope for a research team including Empa scientists.
