A study led by researchers from the Higher Council for Scientific Research (CSIC) has revealed that about a ton of material from comet 21P / Giacobini-Zinner was deposited in the Earth's atmosphere on October 8 and 9, 2011, during one of the The most intense falling star showers of the last decade, which recorded an activity of just over 400 meteors per hour.

Researchers at the University of Minnesota (USA) have developed a brain-computer interface that allows controlling the flight of a helicopter using only the mind. The research will help people with disabilities or neurological problems to increase their independence.
Why have most birds, which reproduce by internal fertilization (within the female) like humans, have lost their penis in the course of evolution? Scientists from the University of Florida (USA) have managed to solve the mystery by showing that, although during development the phallus of embryos of gallinaceous birds begins to grow, from a certain moment a gene called Bmp4 activates a process of programmed cell death.
A kind of gigantic Colorado Canyon on the red planet. This is Kasei Valles, one of the largest river channel systems that occupies 1,550,000 square kilometers of Mars and whose height exceeds 3,000 meters in some points. The canal begins near the Valles Marineris and ends in the vast plain of Chryse Planitia. We show it to you in photographs.
In the last 37 years, temperatures have risen, and these changes have had an effect on the composition of the Drosophila subsurface fly, one of the most common on the European continent. These are the conclusions of a study carried out by researchers from the Autonomous University of Barcelona, who have analyzed the evolution of the genome of this species since 1976.
An international team of researchers has announced in Nature the discovery of the oldest fossil primate skeleton in the world. It belongs to a hitherto unknown species that lived 55 million years ago and has been baptized as Archicebus achilles. His remains were buried at the bottom of an ancient lake in China's Hubeu province, near the current course of the Yangtze River.
Researchers from the University of Gerona and the Federal Institute of Technology in Zurich (Switzerland) have shown that since the eighties the solar radiation that reaches the Iberian Peninsula has increased by 2.3% every decade. The increase is related to a lower presence of clouds. The work has been published in the magazine 'Global and Planetary Change'.
