A study published in the journal Proceedings of the National Academy of Sciences claims to have identified the location of two million barrels of submerged oil thought to be trapped in the deep ocean following the 2010 Deepwater Horizon spill. By analyzing data from more than 3,000 samples collected at 534 locations over 12 expeditions, they identified a 1,250-square-mile patch of the deep sea floor upon which 2 to 16 percent of the discharged oil was deposited. The fallout of oil to the sea floor created thin deposits most intensive to the southwest of the Macondo well. The oil was most concentrated within the top half inch of the sea floor and was patchy even at the scale of a few feet.

Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. Researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. The study results were published the journal Science (pay wall). “Our study suggests that changes in the storage of heat in the deep ocean could be as important to climate change as other hypotheses – tectonic activity or a drop in the carbon dioxide level – and likely led to one of the major climate transitions of the past 30 million years," said one of the authors.

In a research article in the journal Cell scientists report that there is a subset of neurons that are vital in social interest of female mice for males during estrus, the sexually receptive phase of their cycle. They say that these neurons are responsive to oxytocin. The level of oxytocin rise when we hug or kiss a loved one.

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions.
