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 …

Earth’s magnetic fields headed towards switch: Rare event believed to have caused extinction of Neanderthal species

By Andre Mitchell | November 8, 2015 Do not be surprised if one day, compasses will point to the south by default instead of the north. The National Aeronautics and Space Administration (NASA) confirmed that the Earth’s magnetic fields are headed towards a complete reversal—a rare event believed to have once caused the wiping out of the Neanderthal species. Principal investigator Bruce Jakosky from the University of Colorado made this announcement recently while discussing how NASA …

Extinction Means Less Mammal Poop To Fertilize The Earth

By Rebekah Marcarelli | October 26, 2015 New research suggests the loss of mammal poop could mean a more barren Earth. The world relies on the nutrient transfer from animal feces to remain fertile, but new research suggest major species declines and extinctions have put this planetary nutrient recycling system in jeopardy. The weakening of this vital system could have a negative impact on ecosystem health, fisheries, and agriculture, the University of Vermont reported. The researchers calculated …

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 …
