All over the planet, mountain glaciers are losing ground. They give in to increasingly constant heat, hollowing out landscapes and upsetting the ecosystems that they have shaped for millennia. However, certain places seemed to escape this trend, embodying a form of reassuring stability. The Perito Moreno, an emblematic glacier of Argentine Patagonia, was long perceived … Read more
Long perceived as icy deserts frozen in time, the Arctic regions are gradually revealing an unsuspected biological complexity. Beneath the apparently inert surface of the ice, invisible life organizes itself, interacts and transforms its environment. It is at the heart of this white matter, in the most exposed areas of the Greenlandic ice cap, that … Read more
They accompany us every day, share our routines, our joys, sometimes our sorrows. Dogs occupy a central place in our lives, but their presence too often remains fleeting. As progress in veterinary medicine accelerates, scientists are trying to understand why some of our companions live longer than others. Throughout the studies, one observation emerges. Canine … Read more
The benefits of fruits recognized since Antiquity The slogan “For your health, eat at least five fruits and vegetables a day” has been appearing on our screens for many years. However, knowledge of the beneficial effects of fruits dates back to ancient times.
Sleeping isn't just about recharging your batteries. During sleep, memory consolidates. But how sleep changes memories remains unclear. To see more clearly, researchers from the University of Hong Kong conducted a study published in 2025 in Communications Biology. Using electroencephalograms (EEG) and in-depth neuronal analyses, they demonstrated that sleep, particularly paradoxical sleep (REM), does not … Read more
The male body sometimes sends its clearest alarm signals in total silence. Well before the chest pain or shortness of breath, another symptom sets in, discreet but indicative of a broader imbalance. Long confined to the intimate domain, erectile dysfunction is gradually emerging as an early marker of vascular health. This disorder, often minimized or … Read more
Long perceived as an environmental problem confined to beaches or the seabed, plastic fragments are now proving to be much more invasive. They enter our daily lives in unsuspected ways, even altering the very composition of the foods we consume. A recent study challenges our benchmarks by demonstrating a widespread presence of microplastics in milk … Read more
Every year, millions of meals result in abdominal pain, fever or much more serious complications. Behind these often trivialized symptoms lies a massive health issue, relegated to the background for too long. The cause is infectious agents as widespread as they are formidable, capable of striking without distinction of continent or social class. While health … Read more
The image we have of glacial Europe readily evokes a white desert, populated by mammoths and reindeer, swept by cold winds from the north. However, beneath this apparent uniformity, certain valleys sheltered unsuspected ecosystems, capable of supporting unexpected fauna. It is in one of these enclaves, nestled along the Upper Rhine, that researchers have uncovered … Read more
Life on Earth has evolved through cataclysms, mass extinctions and climatic upheavals. However, certain biological forms seem to have gone through these ordeals without failing. Among them, a tiny organism intrigues as much as it fascinates scientists. Behind its apparent simplicity, the tardigrade hides an extraordinary capacity for resistance, now at the heart of a … Read more
