    New findings from Colorado’s rock formations provide physical evidence supporting the Snowball Earth theory, which suggests Earth was once frozen entirely, down to the equator. This study offers insights into a key phase of climate and life evolution. Credit: SciTechDaily.com Evidence from Colorado suggests glaciers once covered Earth to the equator, supporting the Snowball Earth theory. This discovery provides insight into early climate shifts and the evolution of life. Geologists have discovered compelling evidence in Colorado that hundreds of millions of years ago, enormous glaciers blanketed Earth as far as the equator, turning the planet into an icicle drifting through...

    During the experiment, 26 participants each sat with their eyes closed in a dark, quiet chamber lined with electrical coils. These coils manipulated the magnetic field inside the chamber such that it remained the same strength as Earth’s natural field but could be pointed in any direction. Participants wore an EEG cap that recorded the electrical activity of their brains while the surrounding magnetic field rotated in various directions. ...Joseph Kirschvink, a neurobiologist and geophysicist at Caltech, and colleagues studied alpha waves to determine whether the brain reacts to changes in magnetic field direction. Alpha waves generally dominate EEG readings...
