Researchers at ETH Zurich achieved a shape memory effect for the first time with objects that are only a few nanometers in size. This can be used to manufacture tiny machinery and robotic devices on the nanoscale. Alloys that can return to their original structure after being deformed have a so-called shape memory.
A new tool for protein sequence generation and design
Researchers have developed a new technique that uses a protein language model for generating protein sequences with comparable properties to natural sequences. The method outperforms traditional models and offers promising potential for protein design. Designing new proteins with specific structure and function is a highly important goal of bioengineering, but the vast size of protein sequence space makes the search for new proteins difficult.

After a decline in 2021, the Swiss FinTech sector grew again in 2022. Insights into the dynamic financial technology market are provided by the results of this year's FinTech study by the Lucerne University of Applied Sciences and Arts. After a decline of around five percent in 2021, the development of the Swiss FinTech sector returned to its usual direction.
A team from the University of Geneva has discovered the mechanisms by which the seed decides to remain in 'hibernation' or to trigger its germination depending on the outside temperature. Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable.
Novel computer components inspired by brain cells
Researchers at Empa, ETH Zurich and the "Politecnico di Milano" are developing a new type of computer component that is more powerful and easier to manufacture than its predecessors. Inspired by the human brain, it is designed to process large amounts of data fast and in an energy-efficient way. In many respects, the human brain is still superior to modern computers.

A new study shows what it will take for the plastics industry to become completely sustainable: lots of recycling combined with the use of CO2 from the air and biomass. It is also the image of plastics that need to change. Plastic is everywhere. Our society cannot do without it: plastics have numerous advantages, are extremely versatile, and are also cost effective.
When it comes to chronic infections and cancer, a particular type of immune cell plays a central role in our defenses. Researchers at the University of Basel have uncovered the key to the tenacity of these immune cells in coping with the marathon that is fighting a chronic infection. Their results lay the foundations for more effective therapies and vaccination strategies.
Researchers have for the first time estimated how probable the accidental release of nanomaterials will be in the future. They based this on models from the nuclear industry. For a risk assessment, the results now have to be linked to information about the hazardous nature of the materials. Every year, more than two million tonnes of nanomaterials are produced and used for a wide variety of consumer goods.
Plants have a powerful warning system in case of attack, based on a sophisticated communication mode. In a study published in the journal "Cell", the group of Prof. Edward Farmer of the University of Lausanne details the mechanism of propagation of the electrical signal essential to this defense process .
Lausanne museum unveils the secrets of the first color photographs
An exhibition on Gabriel Lippmann, the inventor of one of the first methods for color photography, opens today at the Photo Elysée museum in Lausanne and will run until 21 May. The exhibition provides a unique glimpse into Lippmann's multispectral imaging technique - for which he was awarded the Nobel Prize - by presenting his original color plates in an entirely novel way, thanks to a joint project with EPFL.

Researchers have managed to take three-dimensional pictures of single nanoparticles using extremely short and strong X-ray pulses. In the future this technique could even be used to make 3D-movies of dynamical processes at the nanoscale. X-ray diffraction has been used for more than a hundred years to understand the structure of crystals or proteins - for instance, in 1952 the well-known double helix structure of the DNA that carries genetic information was discovered in this way.
Forest soils store large amounts of organic carbon. When storms devastate the forest, this carbon is lost and a large part enters the atmosphere as CO2. Mountain forests are particularly vulnerable to such carbon losses, shows a study by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL.
To mark the tenth annual UN World Wildlife Day, we compiled a sample of EPFL research projects that are using technology to protect and preserve wildlife. Everywhere you look, biodiversity is under threat. According to the World Wildlife Fund (WWF), wildlife populations have plummeted by 69% since 1970.
Scientists improve the accuracy of weather and climate models
Scientists from EPFL and the WSL Institute for Snow and Avalanche Research SLF have developed a program that improves the accuracy of a widely used weather forecasting model by incorporating surface phenomena that weren't previously taken into account. Given the challenges associated with climate change and the energy transition, it's essential for weather and climate forecasters to be able to accurately predict what happens to snowfall.

A team of biologists led by UNIGE and UNIL has discovered how to awaken neural stem cells and reactivate them in adult mice. Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood.
A fan-shaped tail with shimmering colors in the peacock, eyes perched at the ends of long stems on either side of the head in the Diopsidae flies. The different finery that males use to distinguish themselves is the "seductive" part of mating. The aggressiveness they show to each other, and especially to females, can have an extremely deleterious effect on the biology of populations.
The next unit at NEST, the research and innovation building of Empa and Eawag, goes by the name of STEP2. For about two years, partners from research and industry have been working on various innovations in the fields of circular economy, digital and industrial fabrication, building envelope and energy systems, turning them into products ready for market entry.
It is known that toxins in tobacco smoke can change our DNA - but where exactly in the genome they do this has been a mystery. A new approach developed by researchers at ETH Zurich now brings light into the darkness. In the future, this could make it easier than ever to determine the safety of many chemical substances.
Researchers have published a method for 3D-printing an ink that contains calcium carbonate-producing bacteria. The 3D-printed mineralized bio-composite is unprecedently strong, light, and environmentally friendly, with a range of applications from art to biomedicine. Nature has an extraordinary knack for producing composite materials that are simultaneously light and strong, porous and rigid - like mollusk shells or bone.
When is remdesivir effective for COVID-19?
Remdesivir was one of the first medications approved for treatment of COVID-19. Clinical studies evaluated its effectiveness, but did not generate conclusive results. A new analysis of the study data shows that a specific group of patients benefits the most from the drug. Since the outbreak of the COVID-19 pandemic, researchers and medical practitioners have made a massive effort to find effective treatments for the illness.
