New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia
CHAPEL HILL ?An enzyme inside a bacterium that grows in the soil of potato fields can -- in a split second -- break down residues of a common powerful pesticide used for killing worms on potatoes, researchers have found.
That may be expensive for farmers but lucky for the environment because Univ...
Sustainable agriculture at the ESA Annual Meeting
...just above-ground approaches. Soil bacteria can affect the growth and success of crop plants by fixing nitrogen, aiding in the uptake of nutrients and decomposing
dead organic matter. Some current farming practices, however, may disrupt the soil ecosystem and decrease the effectiveness of the microbe community. ...
Cleaning the atmosphere of carbon: African forests out of balance
...tanding the causes of this African forest carbon sink and projecting its future is anything but straightforward.
Growing trees absorb carbon. Dead, decomposing
trees release carbon. Researchers expect growth and death to approximately balance each other out in mature, undisturbed forests, and thus for total t...
Ancient geologic escape hatches mistaken for tube worms
... siboglinids, look like long lipstick tubes and have been observed in warm and cold environments on the ocean floor, as well as in whale carcasses and decomposing

On the positive side, the study also found certain proteins and such natural organic matter as humic acids may mitigate the effects of decomposing
quantum dots by coating them or by complexing the metal ions released, making them less toxic.
The researchers cautioned that short-term studies c...
Oil spray reduces greenhouse gas emissions from pig finishing barns

"Not one of the more than 250 living primate species is a scavenger," says Sussman. "They are not scavengers because they avoid decomposing

For the analysis, Manzoni assembled a database of more than 2,800 samples of decomposing
