When magpies Dexter Seasons 1-5 DVD Boxset marked with a red or yellow dot that was visible to the birds only in a mirror, they scratched the dot. To prove the birds scratched the dot because they recognized themselves in the mirror - and not because they were investigating what had been done to them - other magpies were marked with a black dot. Those birds didn't scratch. This means self-awareness isn't limited to mammals. It also means birdbrains are brainier than we'd previously thought.The Office Seasons 1-7 DVD Boxset German study done by the University of Duisburg-Essen found that cows can sense the Earth's magnetic field. Using Google Earth, the researchers looked at more than 8,500 cows in 300 pastures all over the world.
They discovered that cows line up their bodies to face north or south when they are grazing or resting - regardless of the sun's position or which direction the wind is blowing. Although birds and bats use internal compasses for navigation, the researchers don't know why cows use theirs. For now they're cowedHouse M.D dvdthe unknown.Scientists recently discovered mice can smell fear. Mice have a tiny bundle of cells in their nose that enables them to smell "alarm pheromones", the chemicals produced when animals are afraid. Mice that had the cells removed showed no fear when exposed to air in which other mice had been euthanized. When mice with the cells in tact were exposed to the same air, they froze in fear. Although fish have the same ability to smell new season of true blood pheromones, scientists have discovered that water pollution can interfere with it.
