A group of scientists from the University of Florida (USA) has identified the oldest Martian meteorite found to date, which would date back more than 1.7 billion years. The rock, barely six centimeters in diameter, would have wandered through space during this time until finally impacting our planet last year in the Sahara desert.
A fractal is a semi-geometric object whose basic structure, fragmented or irregular, is repeated at different scales. The term was proposed by the mathematician Benoît Mandelbrot in 1975, who passed away the week
Mars is no longer what it was. This NASA 3D recreation shows how scientists believe the red planet was 4 billion years ago, much more like Earth than today. In fact, researchers recently discovered, Mars had an oxygen-rich atmosphere precisely 4 billion years ago, long before atmospheric oxygen emerged about 2.5 billion years ago.

Scientists were already predicting it: Comet ISON would be visible to the naked eye at the end of November, despite the fact that the point of closest approach to Earth would not occur until December. However, a burst of activity has advanced that moment and can already be observed thanks to the increase in its brightness. Comets are small, frozen solid bodies that change as their temperature increases as they approach the Sun.
The first big cat to inhabit the Earth could do so millions of years earlier than paleontologists believed. This is the conclusion of the scientists who have just identified the remains of a fossil found in the Himalayas three years ago, documenting a new species of feline similar to the snow leopard.
When we surf the internet, what is called a 'banner' frequently appears, a form of online advertisement that usually includes images or animations and whose objective is to capture our attention to attract us to another website where a product or service is offered.

A team of researchers from the Max Plank Center for Psycholinguistics in Nijmegen (Netherlands) has discovered, after analyzing ten different languages, that the interjection used to show incomprehension is similar in all of them. The "Huh?" in Spanish, "Huh?" in English and "Hein?" in French they would already reveal said phonetic similarity, a sign that the expression has a greater relevance in interpersonal communication than expected.
