Latest Earth's magnetic field Stories

2014-02-25 08:21:32

SAN DIEGO, Feb. 25, 2014 /PRNewswire/ -- Science fiction sometimes foreshadows science fact. Remember the movie Forbidden Planet and the Martian epic Total Recall? Each had within their planets powerful alien-built reactors. The evidence continues to build that Earth contains a powerful nuclear fission reactor at its center, not made by aliens or humans, but by Mother Nature. J. Marvin Herndon presents the scientific basis, evidence and implications accumulated over the past 20...

Dogs Poop According To The Earth's Magnetic Field
2014-01-03 04:44:08

redOrbit Staff & Wire Reports - Your Universe Online Ever wonder why your dog turns in circles before relieving himself? A new study published Friday in the journal Frontiers in Zoology may hold the answer. The researchers discovered that dogs of a variety of breeds align their bodies with the Earth’s magnetic field before squatting, and even the smallest fluctuations in the magnetic field will affect the dogs’ position. The researchers at Czech University of Life Sciences...

Oil Drilling Costs, Impacts Improved Using Modern Compass Technology
2013-12-20 08:05:12

Gerard LeBlond for redorbit.com - Your Universe Online Oil and gas drilling companies are using the Earth’s magnetic field along with modern technology to reduce the cost and decrease the environmental impact while increasing production. The technology being used was discussed in the 2013 fall issue of Oilfield Review. It also emphasizes on the public-private partnership between the US Geological Survey (USGS) and partners to employ this technology and its uses around the world....

Recalling The 2003 Nightmare Halloween Magnetic Storm
2013-10-30 08:32:39

[ Watch the Video: Is There Space Weather In Store For Trick-Or-Treaters? ] Lawrence LeBlond for redOrbit.com - Your Universe Online As Halloween approaches, most people are thinking about costume parties, tricks and treats, haunted hayrides and perhaps a rogue werewolf running amok. But for scientists, this October 31 may provide a scare much different from what most kids get when they go Trick-or-Treating this All Hallow's Eve. The NOAA/NWS Space Weather Prediction Center on...

lightning strikes affect mountain tops
2013-10-15 10:20:36

[ Watch the Video: Lightning Strikes Can Change Mountains ] Brett Smith for redOrbit.com - Your Universe Online Using a simple magnetic compass and a little ingenuity, researchers from the University of the Witwatersrand in Johannesburg, South Africa have found that lighting strikes have a far greater impact on mountaintops than previously thought, according to a report of their experiments in the journal Geomorphology. During powerful thunderstorms, lightning strikes can hit rocks...

Researchers May Have Solved The Spin Mystery Of Earth's Core
2013-09-17 06:18:52

April Flowers for redOrbit.com - Your Universe Online For the last 300 years at least, we have been questioning what direction the center of the earth spins. A group of scientists from the University of Leeds, UK, and the Swiss Federal Institute of Technology may have found the answer. According to the study, published in Proceedings of the National Academy of Sciences (PNAS), the Earth's inner core - made of solid iron - "superrotates" in eastward directions. This means it spins faster...

NASA’s dramatic video of a black-topped sun on the verge of flipping its magnetic polarity has captivated people. Friends of Science say the current low solar sunspot activity, not seen in 200 years, is a pattern that historically preceded global cooling and that the sun is the main driver of climate change, not carbon dioxide. Calgary, Alberta, Canada (PRWEB) August 15, 2013 Climate change on earth is significantly affected by the changing 11 year solar magnetic cycles, according to...

Salmon Use Magnetic Maps To Navigate Home
2013-02-08 10:14:44

April Flowers for redOrbit.com - Your Universe Online A new analysis of over 56 years of data has revealed that sockeye salmon use a magnetic map to return to their spawning grounds after years at sea. The findings of this study were published online in the journal Current Biology. "To find their way back home across thousands of kilometers of ocean, salmon imprint on the magnetic field that exists where they first enter the sea as juveniles," said Nathan Putman of Oregon State...

Rapid Changes In The Earths Core
2012-10-23 05:44:09

Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the journal Proceedings of the National Academy of Sciences (PNAS) said the magnetic gravity fields of Earth are going through some changes. Earth's magnetic field is generated by flows of liquid iron in the outer core. The Earth's magnetic field protects us from cosmic radiation particles. By understanding these processes in the outer core, scientists are able to have a better grasp of the terrestrial shield....

41,000 years ago, a complete and rapid reversal of the geomagnetic field occured. Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north. Moreover, data obtained by the research team formed around GFZ researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, together with additional data from other studies in the North...
