Discovery of long-sought biological compass claimed

… sense magnetism. It might also become an invaluable tool for using magnetic fields to control cells, report researchers led by biophysicist Xie Can at Peking University in Beijing, in a paper published on 16 November in Nature Materials (S. Qin et al. Nature Mater., 2015). “It’s an extraordinary paper,” says Peter Hore, a biochemist at the University of Oxford, UK. But Xie’s team has not shown that the complex actually behaves as a biocompass inside living cells, nor explained exactly …

Big animals’ extinction forever alters environment, study shows

… them,according to a joint report by UC Berkeley, Stanford University, California State University Sacramento and the University of Chile. “Ecological studies have shown that if you pull out a top predator or a key herbivore today, you get dramatic change in the ecosystem,” said Anthony Barnosky, a UC Berkeley professor of integrative biology and the study leader. “Our study makes it clear that in the past, such changes have lasted for thousands of years. These extinctions really do …

Scuba divers in Bahamas find trove of extinct animal fossils and clues to a scientific mystery

… island of Abaco and, in many cases, become extinct altogether. A new report in the Proceedings of the National Academies of Science describes the discovery, and the authors believe it has implications for one of the great mysteries in science — the wave of extinctions in the Americas at the end of the Pleistocene as the climate changed, and human beings arrived. It may also help us think about our present and future impact on an increasingly stressed biosphere. To continue reading this …

Desmatochelys padillai: Paleontologists Find Oldest Known Species of Sea Turtle | Paleontology | Sci-News.com

… Wikipedia is no longer up to date. We described a fossil sea turtle from Colombia that is about 10 million years older,” Dr Cadena said. “The turtle described by us as Desmatochelys padillai originates from Cretaceous sediments and is at least 120 million years old.” The partial skeleton of Desmatochelys padillai, with a length of nearly 6.5 feet (2 m), shows all of the characteristic traits of modern marine turtles, the paleontologists report online today in the journal PaleoBios. To …
