Although the ability to sense magnetic fields has been a long-established fact for a multitude of animal species, experiments searching for magnetoreceptive capabilities in humans have come up empty-handed. A new study may change our view on this seeming disability, having found evidence that our brains register changes in theread more
Scientists have detected that the earth’s magnetic field has been significantly weakening over the past six months. Data collated by the European Space Agency (ESA) Swarm satellite array indicates that the field has developed several weak areas over the Western Hemisphere.
Conversely, the field has strengthened in other areas such as the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites.

Different Things are happening at the top and bottom of our world: Antarctica is gaining MORE ice, at the same time that glaciers are melting in the Arctic. What’s causing this strange discrepancy? The wind.
Changing wind patterns around Antarctica have caused a small increase in sea ice, as a result of cold winds off the continent blowing ice away from the coastline.

Some of the same species are living on BOTH ENDS of the earth?how in the world did this happen?
In BBC News, Mark Kinver quotes researcher Ron O’Dor as saying, “Some of the more obvious species like birds and whales migrate between the poles on an annual basis.” It’s the small, non-migrating species, like sea cucumbers and snails, that are found in both the Arctic and Antarctic that baffle scientists. Did they hitch a ride on a whale?
Kinver quotes O’Dor as saying, “The oceans are a mixing ground. There are all kinds of currents that allow things to move around.” Scientists call these “conveyor belt” currents.
