In a new approach to security that unites technology and art, EPFL researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.

EPFL researchers have uncovered the intricacies of gene expression rhythms in humans, shedding new light on how sex and age influence our body clocks.

Three institutes in the ETH Domain are conducting research on so-called perovskite-based optoelectronics, such as solar cells, photodetectors, and light-emitting diodes (LEDs). In a project called AMYS, labs of EPFL, ETH Zurich and Empa have now joined forces for four years to explore new chemical compositions, but also simple and scalable low cost production methods.

The Standard Model of particle physics describes our visible universe with incredible precision. Yet researchers are not entirely satisfied with it and are trying to find gaps in the theory. PSI’s unique infrastructures play a key part in their mind-boggling experiments.

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.

Electronic components are becoming smaller, more complex and more powerful – this calls for new solutions for joining them. An Empa team is developing nanostructured joining materials for the next generation of microelectronics and other demanding applications.

Replacement parts for car repairs have a negative impact on the environment. By consistently repairing instead of replacing windshields and bumpers alone, Switzerland could save over 1000 tons of CO₂ per year. The insurance company AXA is now offering an assessment for repair workshops and introducing an industry label – based, among other things, on a study led by Empa researchers.

Whether rooftop solar panels are worth the cost is largely dependent in Switzerland on local compensation rates for solar power and on electricity prices in general – these are the findings of a study by researchers at ETH Zurich and the University of Bern. Many power grid operators pay too little, thereby limiting the expansion of solar power.

A research collaboration led by ETH Zurich and MIT will receive a further USD 15 million from the New York-based Simons Foundation to investigate the behaviour of marine bacteria and microalgae. The research will focus on microbial communities that impact the ocean’s carbon cycle.

Efforts to restore degraded ecosystems have so far fallen short of meeting global targets. Sound restoration must better incorporate social processes promoting equity in order to effectively benefit people, climate and biodiversity, says Sara Löfqvist.

One of the greatest unknowns in climate change is the question of how particulate matter affects clouds. Yu Wang is using machine learning and satellite data to investigate the surprising role of these tiny particles in the atmosphere.

EPFL 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.

Switzerland's groundwater is home to a multitude of hitherto unknown organisms. An Eawag research project is shining a light into the darkness and revealing this habitat’s exceptional biodiversity.

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.

Empa researchers want to develop a novel type of insulating material from plant-based raw materials or waste products that can permanently bind the CO₂ it contains by means of a special heat treatment – and thus act as a CO₂ sink. What's more, once the buildings have been deconstructed, this "biochar" and the CO₂ it contains can be used in agriculture to increase soil fertility. The promising idea convinced several funding institutions, which are now supporting the concept financially.
