Scientists measure the distance to stars by their music
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe. For most of us, the countless bright spots in the nighttime sky all seem to be stars.

Experts revive ancient techniques to make concrete more sustainable
Experts revive ancient techniques to make concrete more sustainable
A team of experts from EPFL, ETH Zurich and a Geneva-based architecture firm has developed a new type of non-reinforced concrete made from stone offcuts. Their method, which reduces the use of carbon-intensive cement-based binders, draws on ancient techniques uncovered in historical archives. Some walls could easily be built without reinforced concrete, a material that accounts for a large share of the construction industry's carbon footprint.

Treating tumors with engineered dendritic cells
Treating tumors with engineered dendritic cells
Cancer biologists at EPFL, UNIGE, and the German Cancer Research Center (Heidelberg) have developed a novel immunotherapy that does not require knowledge of a tumor's antigenic makeup. The new results may pave the way to first-in-kind clinical applications. Dendritic cells (DCs) work at the forefront of the immune system.

Scientists explore hidden dynamics in peat under mosses and shrubs
Scientists explore hidden dynamics in peat under mosses and shrubs
Global warming is causing extensive changes to peatland vegetation in Europe and Western Siberia, with consequences for soil composition and the peatlands' ability to sequester carbon. An EPFL-led study has examined the mechanisms behind these complex processes. Peatlands are significant carbon sinks, meaning they're potential time bombs when it comes to greenhouse gas emissions.

AI helps detecting plastic in oceans
AI helps detecting plastic in oceans
A research team from EPFL and Wageningen University has developed a new artificial intelligence model that recognises floating plastics much more accurately in satellite images than before. This could help to systematically remove plastic litter from the oceans with ships. Our society relies heavily on plastic products and the amount of plastic waste is expected to increase in the future.

Is there a physiological explanation behind experiencing glare?
Is there a physiological explanation behind experiencing glare?
Understanding glare is important for improving visual comfort in the built environment. Specific pigments in the eye reduce perception of glare from a blue colored light source, but the pigments do not explain sensitivity to neutrally colored light, scientists show. What is glare? Simply put, glare is visual discomfort often leading to annoyance, fatigue or even headaches.

How the COVID-19 virus makes itself more infectious
How the COVID-19 virus makes itself more infectious
Scientists at EPFL have uncovered a cunning strategy that SARS-CoV-2, the virus that causes COVID-19, uses to increase its infectivity. SARS-CoV-2, the novel coronavirus first identified in late 2019, has since spread globally, leading to the COVID-19 pandemic that has affected millions. As countries grapple with its health, social, and economic impacts, scientists and researchers worldwide have been working tirelessly to understand the virus better and develop effective treatments and vaccines.
