An artist's interpretation of <i>Rusingoryx atopocranion</i> on the Late Pleistocene plains of what is now Rusinga Island, Lake Victoria. Scientists have found many links between <i>Rusingoryx</i> and hadrosaur dinosaurs -- particularly the large, hollow dome that makes a crest on top of the animal's skull.By poring over the fossilized skulls of ancient wildebeest-like animals (Rusingoryx atopocranion) unearthed on Kenya's Rusinga Island, researchers have discovered that the little-known hoofed mammals had a very unusual, trumpet-like...

Lithium battery catalyst found to harm key soil microorganism

<I>Shewanella oneidensis</I> is a ubiquitous, globally distributed soil bacterium. In nature, the microbe thrives on metal ions, converting them to metals like iron that serve as nutrients for other microbes. The bacterium was shown to be harmed by the compound nickel manganese cobalt oxide, which is produced in nanoparticle form and is the material poised to become the dominant material in the lithium ion batteries that will power portable electronics and electric vehicles.The material at the heart of the lithium ion batteries that power electric vehicles, laptop computers and smartphones has been shown to impair a key soil bacterium, according to new...
