Discovery of long-sought biological compass claimed

By David Cyranoski | November 16, 2015 Protein complex offers explanation for how animals sense Earth’s magnetic pull. In the cells of fruit flies, Chinese scientists say that they have found a biological compass needle: a rod-shaped complex of proteins that can align with Earth’s weak magnetic field. The biocompass — whose constituent proteins exist in related forms in other species, including humans — could explain a long-standing puzzle: how animals such as birds and insects …

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 …

Fossils suggest animals and not a meteorite wiped out planet’s first ‘Ediacarans’ microbes | Daily Mail Online

By Ellie Zolfagharifard for DailyMail.com | September 3, 2015 Did critters cause Earth’s first mass extinction? Fossils suggest animals and not a meteorite wiped out planet’s first microbes Earth’s first ever mass extinction event took place 540 million years ago This is when Ediacarans – immobile, tube-like creatures – were wiped out Some evolved into animals such as, mollusks, anthropoids and jellyfish It was these hungry creatures that killed off early Ediacarans, …
