Simulations reveal how saltwater behaves in Earth's mantle

Scientists estimate that the Earth's mantle holds as much water as all the oceans on the planet, but understanding how this water behaves is difficult. Water in the mantle exists under high pressure and at elevated temperatures, ...

Earth's lower mantle can be oxidized in the presence of water

If we took a journey from Earth's surface to the center, the midway point is roughly at 1900 km depth in the lower mantle. The lower mantle ranges from 660 to 2900 km depth and occupies 55% of our planet by volume. The chemical ...

Scientists lead study of galaxy's 'water worlds'

Astrophysical observations have shown that Neptune-like water-rich exoplanets are common in our galaxy. These "water worlds" are believed to be covered with a thick layer of water, hundreds to thousands of miles deep, above ...

10 years after BP spill: Oil drilled deeper; rules relaxed

Ten years after an oil rig explosion killed 11 workers and unleashed an environmental nightmare in the Gulf of Mexico, companies are drilling into deeper and deeper waters, where the payoffs can be huge but the risks are ...

Images of 'invisible' holes on cells may jumpstart research

High blood pressure, inflammation, and the sensation of pain may rely in part on tiny holes on the surface of cells, called pores. Living cells react to the environment, often by allowing water and other molecules to pass ...
