...certain where the water came from, though a collision with an icy comet is likely. Just as important as the origin of the ice is its future. "Settlers could break the water into oxygen and hydrogen and turn them into rocket fuel and air," suggests Dunston. And as for the possibility of ice-dwelling organisms? Not likely. Water may help sustain life, but at nearly 400[degrees] below, it couldn't get started in the first place...
...asphyxiate herself with a garden hose connected to an auto exhaust pipe. Within minutes, nine paramedics and fire fighters aboard two pumper trucks, a battalion fire chief in a Ford Bronco and a pair of medics from a private ambulance company had converged on the scene to administer oxygen to the woman and transport her to a hospital. Across this Denver suburb, a variety of rescue scenes were being repeated in similar all-hands fashion. Boasts fire chief Ray Barnes: "When lives are at stake, we want the fullest emergency response possible...
...replacing the nitrogen atom with an oxygen atom, researchers found that the new compounds bound specifically to dopamine transporters as well as other transporters in the brain such as serotonin and norepinephrine...
Witnesses portrayed the crash as a horrific consequence of a chain of irresponsibility shared by ValuJet, SabreTech (one of the airline's maintenance companies) and ultimately the Federal Aviation Administration. Volatile oxygen-generating canisters were incorrectly marked empty, packed in cardboard boxes that lacked hazardous-warning labels, and stowed in the cargo hold of the DC-9 without required safety caps designed to prevent discharges that could start a fire...
Like all organisms, cells produce waste as they metabolize energy. One of the most troublesome by-products of this process is a species of oxygen molecule known as a free radical--essentially an ordinary molecule with an extra electron. This addition creates an electrical imbalance that the molecule seeks to rectify by careening about, trying to bond with other molecules or structures, including DNA. A lifetime of this can lead to a lot of damaged cells, which may lead to a range of disorders, including cancer and the more generalized symptoms of aging like wrinkles and arthritis...
