Mathematicians have come up with a new way to crinkle up the fabric of space-time -- at least in theory.

Humans get most of the blame for climate change with little attention paid to the contribution of other natural forces. Now, scientists are shedding light on one potential cause of the cooling trend of the past 45 million years that has everything to do with the chemistry of the world's oceans.

Researchers in the Netherlands have developed a coating with a surface that repairs itself after damage.

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators use to hunt their prey.

Clément Gilbert, chercheur au CNRS et Cédric Feschotte, professeur à l'université du Texas, expliquent que 8 % du génome humain est constitué d'éléments fournis par des virus, que nous avons recyclés pour certaines de nos fonctions cellulaires.

It took some 10 million years for Earth to recover from the greatest mass extinction of all time, latest research has revealed.

A new type of male contraceptive could be created thanks to the discovery of a key gene essential for sperm development.

Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied.

Many people anticipating the creation of an invisibility cloak might be surprised to learn that a group of American researchers has created 25,000 individual cloaks.

Scientists have, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells.

Un trou d'une taille équivalente à cinq fois la surface de l'Allemagne s'est ouvert dans la couche d'ozone au-dessus de l'Arctique, égalant pour la première fois la diminution observée dans l'Antarctique.

The physical model to describe the hydrophobic interactions of molecules has been a mystery that has challenged scientists and engineers since the 19th century. Researchers have developed a method to study these forces at the atomic level, and have for the first time defined a mathematical equation.

Engineers and physicists have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate.

In recent decades, Arctic sea ice has suffered a dramatic decline that exceeds climate model predictions. The unexpected rate of ice shrinkage has now been explained. Researchers argue that models underestimate the rate of ice thinning, which is actually about four times faster than calculations.
