At least 29 recruits died during basic training at law enforcement academies around the country in the last decade, an AP investigation found.

A new study has challenged conventional wisdom on oxygen reduction reaction (ORR) catalysts by uncovering a novel reaction ...

Researchers have discovered an "unexpected" accumulation of the radioactive isotope beryllium-10, deep underneath the surface of the Pacific Ocean. As detailed in a paper published in the journal ...

A team of researchers has found an unusual spike in beryllium-10 levels in the Pacific seabed, dating back 10 million years.

Groundwater is water stored beneath the Earth's surface in the spaces between rocks and sediments, collectively known as aquifers.

We collected 10–50 mg of enamel for carbon, nitrogen, and oxygen isotope analyses, which were measured in duplicate or triplicate whenever possible. At each sampling site, 30 ml of unfiltered water ...

Introduction: Recent work has proposed that the nitrogen isotopes in marine sediments can be impacted ... About 0.2 g of sediment was added into a 15 mL centrifuge tube and acidified by about 15 mL of ...

Scientists recently reported an unexpected deep-sea development in the Pacific: certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean. This ...
