Component of volcanic gas may have played a significant role in the origins of life on Earth

...lfide. Carbonyl sulfide is present in volcanic gasses and deep sea vent emissions today, and since these geological phenomena were prominent features on the early Earth, it is reasonable to assume that the gas was present. In their report, the scientists demonstrate that the gas can bring about a vi...

Delays in cutting greenhouse gasses could harm environment

...ssful efforts to stabilize the level of greenhouse gasses in the atmosphere could still result in serious ec...t three possible goals: stabilizing all greenhouse gasses at levels equivalent to 500, 600 or 700 parts per million of carbon dioxide, which is the chief huma...

Scripps research scientists discover new key to pulmonary edema in respiratory distress syndrome

...i. When a tiny portion of air reaches the alveoli, gasses are easily dissolved into the fluid, and then exchanged with molecules in the adjacent bloodstream. One physiology that enables this exchange is the lung epithelium, the specialized layer of cells immediately lining the air sacs. The epithelium is he...

...rtant in understanding bubbles formed of dissolved gasses in other situations, such as nitrogen bubbles that grow in the blood vessels of surfacing divers and can cause decompression sickness, and the explosive release of carbon dioxide gas from Cameroon's Lake Nyos that killed over 1800 people in 1986. T...

...tive clothing and the physical laws that dangerous gasses (and the like) must adhere to. A key focal point of the research is determining at which point in time the clothing loses its effectiveness. At a certain point, the absorbent carbon layers in the clothing become saturated, whereby the protective fu...

...) Soil is a reactive surface in which heat, water, gasses and chemical elements are absorbed, stored and transmitted. Biogeochemical processes that occur on this surface play a key part in many ecosystems. Soil scientists, chemists, physicists and biologists will collaborate in the Priority Programme "Bioge...

North Pole's ancient past holds lessons for future global warming

...Haven, Conn. -- Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature. An expedition to the Artic Ocean in 2004 by a ...
