Plasmodium, a protozoan responsible for malaria, flourishes in the human body, growing inside red blood cells until the cells burst. And without enough red cells to carry oxygen through the body, humans become anemic and can die from renal failure or convulsions. Bacteria, which are considerably smaller than protozoans, generally do their damage indirectly, producing toxins that stimulate the body to mount an immune response. Ideally the immune cells kill the bacteria. But if the bacteria get out of control, their poisons can either kill cells or generate a huge immune reaction that is itself toxic...
...tend to be a mixture of ice, rock and dust, along with substances, like carbon monoxide, that evaporate easily to form a halo and a tail. Scientists studying the chemical composition of the spots on Jupiter where S-L 9 hit thought they might see evidence of water and oxygen, two of the expected products when an icy comet vaporizes. But except for one unconfirmed report,researchers have found only ammonia, hydrogen sulfide and sulfur...
...Storm King fighters were apparently working below the fire's edge, trying to keep it from creeping down the 1,000 ft. to where it would menace the traffic on Interstate 70. Suddenly the wind wheeled around 180 degrees and began gusting at 47 m.p.h. The fresh infusion of oxygen into superheated air created a blowup, an unconfined explosion of unimaginable power. In a matter of moments, the fire above those on the slope had also become the fire below them...
...this any place to drill for oil? the temperature plunges to -40F in winter, then soars to 120F in summer, when swarms of mosquitoes make life even more unbearable. On top of that, workers must wear gas masks and carry oxygen packs, since just a whiff of the invisible hydrosulfide gas that seeps from the ground can cause instant death. "In winter it is difficult to motivate anyone to work," says Larry Barthold, general manager of the joint venture that U.S. oil giant Chevron and the former Soviet republic of Kazakhstan have formed to tap the wealth that lies...
...disease is treated with blood transfusions, which replace defective red blood cells. Those cells, when functioning properly, carry oxygen throughout the body...
