...Researchers at SEAS are also developing innovative fuel cells, but moving away from traditional fuels like hydrogen and oxygen to hydrocarbons...
Burn almost any kind of organic material - corn husks, hazelnut shells, bamboo and, yes, even chicken manure - in an oxygen-depleted process called pyrolysis, and you generate gases and heat that can be used as energy. What remains is a solid - biochar - that sequesters carbon, keeping CO2 out of the atmosphere. In principle, at least, you create energy in a way that is not just carbon neutral, but carbon negative...
...team researched the bacteria Shewanella oneidensis, affectionately known as Shewie. It is a specie capable of performing anaerobic metabolism in oxygen-poor environments and of donating electrons to surrounding substrates...
...graduate student who was performing the experiment, Tsing-Hua Her, noticed immediately that something was amiss when he combined the silicon with halogen gas: the silicon had turned black, but the material couldn’t have been burned, since there was no oxygen present in the chamber. Under the microscope, Her and Mazur saw, the surface of the wafers displayed a forest of tiny spikes...
...died from other causes. Researchers found that SIDS babies often have a brain defect in a region of the brain that controls breathing, heart rate and blood pressure. The abnormality appears to weaken the responsiveness of certain functions, including arousal from sleep when the body fails to get enough oxygen. Researchers think the defect may be genetic in origin, although there are no biological tests yet to determine risk...
