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 …

Bees prefer cities to rural areas as mass crops blamed for decline | Daily Mail Online

By Fiona Macrae, Science Correspondent for The Daily Mail | April 1, 2015 We think of them as thriving in wildflower meadows and rolling fields. But new research suggests Britain’s bees are happier near towns and cities. A study of wildlife sites across four English counties has found that most are home to fewer species of bee today than they were in the past.

It wasn’t the first time I had mourned the fading of the firefly.  The National Wildlife Federation says that fireflies live in fields, meadows, …
