Imitating a science fiction robot doesn't just require memory. This requires appropriate acoustic precision, muscular control and vocal architecture. When the birds try the mechanical sounds of R2-D2, not all start with the same advantages. By comparing these performances, researchers reveal unexpected abilities in an imitative bird that is much more formidable than the parrot. … Read more
Medicine relentlessly seeks to diagnose diseases before they take hold. Heart failure, often silent at first, still too often escapes the clinical radar. What if a few drops of saliva were enough to change things? This is what seems to indicate a series of studies which rely on a trio of proteins to spot the … Read more
On Mars, strange dark streaks streak the slopes of volcanoes and craters. Spotted in the 1970s, these marks have long been interpreted as traces of flows linked to the presence of water. But despite decades of orbital observations, their exact origin remained uncertain. A team of researchers from the Center for Space and Habitability at … Read more
The determinants of health are no longer limited to biological or medical factors. Certain everyday behaviors, perceived as trivial or purely civic, in reality reveal deeper inequalities. Among them, the simple fact of voting or not draws a still little-known dividing line. The link between voting behavior and mortality, highlighted by a Finnish study, raises … Read more
The Earth's magnetic field acts as an invisible shield, deflecting solar particles that constantly bombard our planet. Without it, radiation would seriously endanger electronic systems, satellites, and especially living organisms. However, this field presents an area of increasing weakness above the South Atlantic, called the South Atlantic Anomaly. Monitored for more than a decade, this … Read more
Intelligence is measured neither by the weight of a brain nor by the size of a body. Certain insects, even though they lack a cortex, manage to accomplish tasks that were thought to be reserved for vertebrates. Their environment, apparently limited, hides much broader cognitive capacities than imagined. Temporal cognition in bumblebees offers a striking … Read more
The food consumption of a French person exceeds 1000 kg per year According to a study carried out by the National Agency for Food, Environmental and Occupational Health Safety (ANSES), in 2017, the French consumed on average 2.9 kg of food + drinks per day. Which corresponds to approximately 1058 kg per year. A significant … Read more
In North America, certain peaks not only create landscapes: they direct the flow of millions of liters of fresh water. Triple Divide Peak, perched at more than 8,000 feet in Montana's Glacier National Park, is one of those rare spots where geography dictates the direction of the rivers. Unique in its kind, this summit constitutes … Read more
Recently, violent solar flares took place, causing a striking and exceptional spectacle in the northern hemisphere with the appearance of the Northern Lights. However, these phenomena occurring 150 million kilometers from Earth are not only responsible for the appearance of celestial glow. No, they can endanger infrastructure in Earth orbit, but also directly on Earth. … Read more
The universe is not frozen in eternal youth. Behind its apparent stability there is a slow transformation, almost imperceptible on a human scale. As the galaxies continue to shine, their light betrays another, more discreet narrative, that of gradual exhaustion. Star formation, the fundamental driver of cosmic evolution, is now showing clear signs of slowing … Read more
