In 2016, scientists published a newspaper with a bold claim: that the giraffe, first described as a species by the Swedish biologist Carl Linnaeus in 1758, is actually always four kinds. Unlike Linneaus, the researchers had access to modern genetic tools, which showed that giraffes fall into distinct clusters based on differences in their DNA, … Read more

Poitiers Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and … Read more
Researchers at Brown University have found that the geometry of fault networks, and not just the friction on fault lines, significantly influences the occurrence and intensity of earthquakes. Credit: SciTechDaily.com Researchers at Brown University found that the geometry of faults, including misalignments and complex structures within fault zones, plays a crucial role in determining the … Read more
