Study of poison frogs the first to show that the Andes Mountains have been a major source of diversity for the Amazon basin. AUSTIN, Texas—Colorful poison frogs in the Amazon owe their great diversity to ancestors that leapt into the region from the Andes Mountains several times during the last 10 million years, a new [...]

Karl Bates and his colleagues in the palaeontology and biomechanics research group have reconstructed the bodies of five dinosaurs, two T. rex (Stan at the Manchester Museum and the Museum of the Rockies cast MOR555), an Acrocanthosaurus atokensis, a Strutiomimum sedens and an Edmontosaurus annectens. The team, whose findings are published in the Public Library [...]

Scientists have sequenced over seventy strains of yeast, the greatest number of genomes for any species. “Analysing so many strains has helped us to bring the small branches of Darwin’s ‘Tree of Life’ into focus,” said Dr Steve James of the National Collection of Yeast Cultures (NCYC) at the Institute of Food Research. “We can [...]
