A Zen discovery: Unrusted iron in ocean

Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or - a surprising new study finds - float up from the sea floor. The discovery, published online ...

Magnetic 'springs' break down marine microplastic pollution

Plastic waste that finds its way into oceans and rivers poses a global environmental threat with damaging health consequences for animals, humans, and ecosystems. Now, using tiny coil-shaped carbon-based magnets, researchers ...

Nanoparticles accumulate quickly in wetland sediment

(Phys.org) —A Duke University team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indirectly damage ...

Southern Ocean iron cycle gives new insight into climate change

An international team of researchers analyzed the available data taken from all previous studies of the Southern Ocean, together with satellite images taken of the area, to quantify the amount of iron supplied to the surface ...

Preliminary study suggests mercury not a risk in dog foods

Researchers at the University of California, Davis, recently investigated levels of methylmercury in a small sampling of commercial dog foods and found good news for dog owners. Of the 24 diets tested, only three were positive ...
