Albert Einstein considered the origin of the Earth's magnetic field one of the five most important unsolved problems in physics. The weakening of the geomagnetic field, which extends from the planet's core into outer space and was first recorded 180 years ago, has raised concern by some for the welfare of the biosphere.

Last winter’s El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years.

Scientists have discovered high levels of extremely toxic chemicals in the most remote place on earth — the 36,000-foot-deep Mariana Trench in the western Pacific Ocean, according to new research published in the journal Natural Ecology and Evolution.

Marine biologists used fish traps and robotic submarines to collect crustaceans from the trench’s seafloor and then measured the level of persistent organic pollutants (POPs) in each specimen.

Fresh insights into how immune cells are regulated could signal a new approach to tackling infections.

A Florida State University researcher is delving into the complexities of exactly how permafrost thawing in the Earth’s most northern regions is cycling back into the atmosphere as carbon dioxide and further fueling climate change.

Answer: It has a lot to do with tiny little bugs called microbes and little to do with sunlight.

Assistant Professor of Earth, Ocean and Atmospheric Science Robert Spencer and a team of researchers traveled to Siberia from 2012 to 2015 to better understand how thawing permafrost affected the carbon cycle. They specifically investigated how the vast amounts of carbon stored in this permafrost transferred to the atmosphere as carbon dioxide.
