For millennia, farming in Switzerland did not reduce plant diversity but helped increase it, researchers have shown in a detailed reconstruction covering the past 7000 years. Only recent decades paint a different picture. The fall of the Roman Empire and major plague outbreaks: These events not only affected people but also reduced plant diversity on […]

When energy storage is discussed in the context of the energy transition, the conversation almost invariably turns to electricity. Solar and wind power have made the temporal mismatch between energy production and energy demand one of the defining challenges of low-carbon energy systems, and technologies capable of storing electrical energy have consequently become central to […]
When astronomers in the eighteenth century first turned powerful telescopes toward the Milky Way, they noticed something puzzling: tight, spherical swarms of stars scattered across the sky. Now we know that each contains hundreds of thousands of suns packed into a region just a few dozen light-years across. These objects, known today as globular clusters […]
Author: Chris Kirkland, Professor of Geochronology, Curtin University In the Pilbara of Western Australia, some of Earth’s oldest rocks lie beneath the sky, as they have for billions of years. They are dark, weathered volcanic rocks, close to 3.5 billion years old, cut by veins and stewed by deep time. Their survival is remarkable. Most […]
Author: José Luis Granados Mateo is a postdoctoral researcher in the Department of Philosophy at the University of the Basque Country (EHU) and a member of the Integrated History and Philosophy of Science (iHPS) research group. His work focuses on history and philosophy of science, science and values, and the epistemology of scientific practices. A […]
Androgenetic alopecia is characterized by a progressive hair loss. This represents a cosmetic issue, treated with a limited set of pharmacological tools such as minoxidil or finasteride. While these therapies can be effective in some patients, their results are often inconsistent and frequently accompanied by unwanted side effects. This has driven researchers to search for […]

Ever since the birth of quantum mechanics in the early twentieth century, chemists have struggled with a fundamental paradox. On one hand, Lewis dot structures and molecular drawings teach us to think of electrons as localized entities—either sitting neatly in lone pairs or shared directly between two bonding atoms. On the other hand, Schrödinger’s wave […]
Authors: Thomas M. Pitot, Chercheur postdoctoral en microbiologie, Université du Québec à Chicoutimi (UQAC) and Catherine Girard, Professeure-Chercheure en microbiologie, Université Laval Viruses play a major role in the functioning of ecosystems. They profoundly influence the dynamics of microbial communities, flow of matter and global biogeochemical cycles. Yet despite their abundance and ecological importance, many […]
The world’s population is growing, people are living longer, and industry continues to expand. These changes bring many benefits, but they can also increase risks to human health. Over time, people are exposed to many substances in the environment, some of which may be harmful. At the same time, greater industrial activity means more chemicals […]
