...altitudes of about 10,000 ft. and higher, mountain climbers run the risk of developing a serious condition in which their lungs fill with water. Now scientists in Switzerland report that inhaling an extremely diluted dose of nitric oxide gas--about the amount present in Los Angeles smog--can help treat the problem...
...there a murderer among the mice? Indeed there was. In a paper published in Nature last week, a team from Johns Hopkins and Massachusetts General Hospital reported that by "knocking out" a gene essential to the synthesis of nitric oxide, an important neurotransmitter in the brains of mice and men, they had inadvertently created a strain of extraordinarily ferocious male rodents (females were unaffected...
Researchers speculate that nitric oxide may effect the emotion-regulating areas of the brain, perhaps by putting the brakes on aggressive male behavior. Could a lack of nitric oxide help explain violent impulses in humans? Scientists caution against making facile comparisons. But they are watching the mad mice of Baltimore closely, looking for clues to treating similar behavior in humans...
...complex as violent behavior in human beings obviously can't be traced to a single gene." The scientists from the Johns Hopkins University School of Arts and Sciences and Massachusetts General Hospital bred the mice to eliminate a working copy of a gene needed to make an enzyme called nitric oxide. The researchers say that nitric oxide may act as a brake on behavior...
...mixture of nitric acid and ethanol creates fumes which are a corrosive irritant. Nitric acid, a strong caustic acid, tends to bubble and splatter whencombined with certain other chemicals...
