About seventeen million years ago, a Short, stockier relative of modern giraffes roamed northern China. His skull was fitted with a thick keratin “helmet” probably used in clashes with rival males for sexual competition. Details of the study are published in the journal Science. A thick neck, a helmeted head Say hello to Discokeryx xiezhi. […]

A recent study published in Nature revealed that large-scale reforestation can increase evaporation, an effect capable of affecting water availability and stream flow. Although reforestation plays a very important role in mitigating the effects of climate change, scientists are not sure that it may be the best alternative to do so. According to the publication, […]

As it moves forward with plans to send astronauts to the Moon, NASA is also already thinking about human exploration of Mars. A first mission involving the sending of four people on site for thirty days would already be in the papers. After the Moon, the planet Mars. This is the stated objective of NASA […]

Towards the end of the Paleozoic, a period of cold climate was interrupted by an episode of temporary but dazzling warming, accompanied by generalized anoxia of the oceans due to a massive release of carbon dioxide, as evidenced by a study published in the magazine PNAS on May 2. About 320 to 270 million years […]

Several British aerospace engineering players are currently considering a major project. The objective would be to assemble a first orbital solar power plant in the mid-2030s. However, the researchers assure that the technology to support such a structure already exists. We know that an orbital solar power plant project has been in the Chinese papers […]

A team of paleontologists announces the discovery of an “exceptionally well-preserved” ancient animal in southern Ontario. The specimen, which had no eyes, moved on the seabed by means of stilts. It evolved about 450 million years ago. The vast majority of fossils are originally made of biosynthesized minerals, which facilitates their preservation. Conversely, soft tissues […]

Atmospheric methane may be the first sign of life beyond Earth detectable by astronomers. While non-biological processes can also generate it, a new study establishes a set of circumstances that may point to true biological activity on a rocky planet. Many technical means, under the tutelage of some of the brightest minds on the planet, […]

Researchers have used the “invisible species” ecological model to estimate the number of medieval chivalrous works and heroic tales lost throughout history. According to this work, more than 90% of these testimonies would have disappeared. Our ancestors left us books, manuscripts, paintings, sculptures and other artefacts that allow us to better understand their cultures. However, […]

Extinction specialists have tried to bring the Christmas Island rat back from the dead. The species had been exterminated in Australia a little over a century ago. To do this, they relied on a related species: the brown rat. Details of the study are published in the journal Current Biology. Deextinction is the process of […]

The venom of the tiger snake and the brown snake makes these two species among the most dangerous in Australia. As part of a study, scientists recently analyzed their genome with the aim of finding out more about their origin. Presentation of the two species The tiger snake (Notechis scutatus) is usually orange-yellow with green […]
