Arnold Kriegstein, a neuroscientist at the University of California, San Francisco, also argues that though the scientists found inhibitory interneurons strikingly depleted in the brains of the oxygen - deprived piglets, this alone can not account for the dramatic shrinking of the animals» overall brain size and the diminished number of cortical folds «The interneurons are part of the story but not the entire story of how the brain is affected by this kind of [lack of oxygen].»

Scientists are keeping a close watch on variables that might affect life in the open ocean, including depleted oxygen levels caused by a feeding frenzy from oil - and gas - eating microbes, and the unknown effects of dispersants, which break the oil into droplets but may keep it suspended in the water.

Researchers suspected that oil might deprive birds of oxygen by affecting hemoglobin, which carries oxygen in the blood.

The researchers used a room calorimeter, a 25m3 furnished chamber that measures movement, oxygen, carbon dioxide, temperature and pressure, to assess how dietary changes affected energy expenditure and the way nutrients were processed by the body.

I suspect detection of TC events by oxygen - 18 ratios is complicated by the fact that oxygen - 18 ratios are also affected by summer to winter precipitation ratios, although the very different timescales make it possible to disentangle such issues.

Further complicating the use of these proxies is the fact that the deviation in oxygen - 18 ratios is affected by the amount of TC rainfall, the distance from the center of the cyclone at which the rain was produced, and the intensity of the cyclone — so I doubt these proxies alone will enable disentangling intensity and rainfall, tnough a large number of samples over an area could reveal information about the track and extent of the TC event.
