Among the challenges on the agenda, one of the most urgent—and least publicized—is the preservation of the night sky, which is now threatened by the proliferation of satellites.

Not so long ago, China was seen as the “world’s factory”—the country to which European industries were relocating. Little by little, that status is changing. One of the most emblematic sectors is the energy sector...

“What’s it called again?” The word is right there. We can feel it within reach, almost within our grasp, “on the tip of our tongue,” but we just can’t seem to say it right away. So we work around it, rephrase it, wait a little...

At Grenoble University Hospital, patients with epilepsy read sentences such as “I’m bumping into something,” “I’m burning myself,” “I’m tasting something,” or “He’s tickling me,” while their brain activity was recorded. The result: the posterior insula...

Various players in the tech industry are considering using satellites to perform computations. In other words, the idea is to send data centers into space. Is this realistic? A computer scientist weighs in.

In late October, Airbus asked airlines to ground 6,000 A320s following an in-flight incident. The company attributed this to a software update that was reportedly more sensitive to radiation...

A new molecule capable of protecting neurons from the toxic effects of chemotherapy, while enhancing the effectiveness of certain cancer treatments, has been discovered and is showing promising results ...

While current regulations require the measurement of concentrations of only certain PFAS, the number of such compounds to be analyzed is still quite limited. Portable sensors and new methods are needed.

A new study, published today in the journal *Nature*, reveals two young exoplanets within an unusual star system.

Animal testing is a topic of debate. Is scientific research ready to do without animals? Are there enough alternatives? In any case, the discussion deserves to be conducted in the most objective...

"Shifting" involves consciously switching from reality to an imaginary experience and perceiving visual or auditory sensations within it.

Snow sometimes takes on unusual colors… and what’s most intriguing is that blood-red snow harbors algae that promote biodiversity in this environment we think of as so “pristine.”

A month ago, the announcement came as a bolt from the blue—even in the darkest skies on Earth—because it threatens astronomers’ observations in the Atacama Desert (Chile).

Some robots are very impressive, but for now they're a little... clunky. Artificial intelligence could make them more adaptable and better suited to our needs.

The question comes up every year, and the answer seems increasingly uncertain. Here’s an update on snowfall trends.

Orbiting a star that is only 2 million years old, astrophysicists have detected a newly formed planet orbiting very close to its star.

Laboratory animals, often mammals, evoke mixed feelings in us. A study reveals how we devalue them in order to more readily accept their use.

The Sun provides us with light, warmth, and a tan. But our star also experiences crises—storms that can have very real repercussions on our societies.

We can see through the windowpane but not through the wall surrounding it. How does physics explain why light does not behave the same way in these two cases?

As the digital world’s environmental footprint grows, can we really envision artificial intelligence that is resource-efficient and has a limited impact?

How did we go from the scientific meaning of the word “algorithm” to the notion of a “black box” with unpredictable and poorly understood results?

To find out when spoken language first appeared, we would need to be able to study the languages of our ancestors. The problem is that languages do not fossilize, so we have to model them.

In 2022, the first “exascale” supercomputer—capable of performing one billion billion operations per second—was unveiled. This technological feat comes with environmental challenges.

Certain medications can be (de)activated by light. This is a promising area of research that could help limit the negative effects of certain treatments.

While it may seem easy to understand a written sentence, how does our brain parse information when it’s spoken? A new model helps explain this phenomenon.

Dark matter remains a mystery; yet it is believed to be six times more abundant than “ordinary” matter. Several laboratories around the world are working to unravel this mystery.

Atmospheric rivers play a role in the water cycle and cause heavy precipitation. Well known in our latitudes, they also affect the poles.

The Northern Lights are very rare in mainland France, but about once every 10 years, it is possible to catch a glimpse of these beautiful lights.

A universal phenomenon in which we associate an object’s name with its shape, the “bouba-kiki effect” is not related to language, but rather to the physics of objects.

This year, supercomputers reached a milestone—performing one billion billion operations per second. Why and how did they get there?

Is experimental research compatible with advances in artificial intelligence systems?

From brain research to recreational applications: brain-machine interfaces—the gap between concrete technological developments and fantasy.

The microbes we know today are the result of billions of years of evolution; some are harmful, while others are essential to our survival.

The DART space probe is set to crash into the moon of an asteroid in the solar system.

Do clouds limit global warming by acting like umbrellas, or do they accelerate it by amplifying the greenhouse effect?

An artificial intelligence system has managed to outperform eight world-class bridge champions.

By measuring a quantum system, it is possible to transfer energy to it and conceive of new “quantum engines” capable of amplifying laser light, for example.

Commitment to animal causes and expressions of empathy toward animals appear, in fact, to be much more common among women than among men. But are these socially constructed roles?

Cell reprogramming is a very promising technique for developing new treatments, but it is not—yet—a fountain of youth.

For the first time, a global atlas has been created to track changes in glaciers.
