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.

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 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.

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.

In two separate studies, researchers at EPFL have carried out extensive tests to develop the best mouse models for studying kidney and liver diseases. The findings provide crucial insights into both conditions, and are expected to open up new avenues of research and treatment. "In these two studies we investigated how the mouse's genetic background affects the susceptibility to fatty liver disease and the transition from acute kidney injury to chronic kidney disease," says Professor Johan Auwerx at EPFL.

Researchers at EPFL have found that infection with a common bacterium that is linked to periodontal disease, oral cancers, and bad breath may cause a small increase in the risk of cardiovascular disease. A combination of genetic and environmental risk factors contributes to heart disease, which is responsible for about a third of all deaths worldwide.

Researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond. Until now, the ability to make electronic devices faster has come down to a simple principle: scaling down transistors and other components.

Architects at EPFL have developed a new, multi-criteria evaluation method to support better decision-making for the redevelopment of brownfield sites in Geneva, Sion and elsewhere along the Rhone.

After four years of research, EPFL's Blue Brain Project shares an enriched version of their 3D digital cell atlas of the mouse brain which includes more neuron types. The new approach can be extended to any other cell type, and provides a resource to build tissue-level models of the mouse brain.

EPFL mathematicians, in collaboration with Purdue University, have settled a 30-year-old question about spheres and 4-dimensional spaces. The results bring new light to the "Euler Class," one of the most powerful tools to understand complicated spaces. For mathematicians, "Euler Class" is one of the most powerful tools for understanding complicated spaces by cutting them into simpler pieces.

In a new approach to security that unites technology and art, researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages. Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL's School of Engineering.

Researchers have uncovered the intricacies of gene expression rhythms in humans, shedding new light on how sex and age influence our body clocks. The human body runs on a finely tuned clock synchronized to the 24-hour cycle of Earth's rotation, known as the circadian clock, which controls various physiological processes such as the sleep-wake cycle, hormone production, and metabolism.

A new microfluidic device developed by scientists in Switzerland can detect the SARS-CoV-2 virus with high accuracy and speed, using a unique DNA/RNA duplex technology. The device can prove to be a game-changer in the fight against the ongoing COVID-19 pandemic. The ongoing COVID-19 pandemic created an urgent need for ways to detect the SARS-CoV-2 virus quickly, accurately and on a massive scale in order to control its spread.

Researchers from EPFL and JTEKT Corporation have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers. Autonomous driving technologies have already been integrated into many mass-produced vehicles, providing human drivers with steering assistance in tasks like centering a vehicle in its lane.

Researchers have combined low-power chip design, machine learning algorithms, and soft implantable electrodes to produce a neural interface that can identify and suppress symptoms of various neurological disorders. Mahsa Shoaran of the Integrated Neurotechnologies Laboratory in the School of Engineering collaborated with Stéphanie Lacour in the Laboratory for Soft Bioelectronic Interfaces to develop NeuralTree: a closed-loop neuromodulation system-on-chip that can detect and alleviate disease symptoms.

Researchers at EPFL have developed a new technique that can visualize and control the rotation of a handful of spins arranged in a vortex-like texture at the fastest speed ever achieved. The breakthrough can advance "spintronics", a technology that includes new types of computer memory, logic gates, and high-precision sensors.

Blood platelets can be stored for only up to a week, and hospitals often run short of this life-saving resource.

In a new journal article, EPFL professor Tom Battin reviews our current understanding of carbon fluxes in the world's river networks. He demonstrates their central role in the global carbon cycle and argues for the creation of a global River Observation System. Until recently, our understanding of the global carbon cycle was largely limited to the world's oceans and terrestrial ecosystems.

Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.
