(PhysOrg.com) -- Based on studies of old volcanic basalt, scientists know that the Earth’s magnetic field reverses at irregular intervals, ranging from tens of thousands to millions of years. Volcanic basalt rock contains ...
(Phys.org) —A new study shows for the first time that microorganisms are thriving deep within the oceanic crust under the sea floor, and hence far from light or oxygen.
Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter ...

An international team of researchers has found evidence that suggests atmospheric CO2 levels at the end of the Triassic era were nearly the same as those predicted for the 21st century. In their paper published in the journal ...
When fossil fuels are burned, carbon dioxide (CO2) is emitted. As the gas rises and becomes trapped in the atmosphere, it retains heat as part of a process called the greenhouse effect. The increased temperatures associated ...
