"It's almost like the oceans are getting ready for a heart attack."
A new study published in Nature says that the overall oxygen content of the ocean has declined by 2% over the past 50 years. Because oxygen is always unevenly distributed in the ocean, that 2% average represents a larger drop in some areas than others. Bacteria in areas of low oxygen tend to produce nitrous oxide, a potent greenhouse gas that has risen in a way similar to CO2 over the decades since the industrial revolution. Low O2 leading to more N2O from the ocean is another likely global warming feedback loop. Projections indicate that we could lose 7% of the ocean's oxygen by 2100. [more inside]

What a thought looks like
Researchers at Japan's National Institute of Genetics have succeeded in imaging neuronal activity in a fish's brain. They showed a genetically modified (to enable easier imaging) fish some food and "correlate[d] neuronal activity in the brain with prey capture behavior." The video is short but cool.
