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 sense magnetism. It […]

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 […]

Snow Leopards might face extinction due to climate change and other factors

By Raymond Valledor | October 26, 2015 Climate change is now another problem for a particular species of this planet and if left unsolved it might lead to the extinction of the snow leopard. The snow leopard has experienced a decline in number due largely to poaching but according to the World Wildlife Fund climate change is now also a factor in its demise. So far there are around 4,000 of these large cats left in […]

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 […]
