Health & Safety
The first clinical trials in 20 years of a vaccine against group A Streptococcus -- the bacterium that causes strep throat -- are now under way, at the University of Maryland's Center for Vaccine Development. Tests of a group A strep vaccine ground to a halt in the 1970s, after some experimentally vaccinated children developed rheumatic fever, which often leads to heart disease. However, scientists continued investigating because of accumulating links between group A strep and pneumonia, toxic shock syndrome, and "flesh-eating" disease. Genetic engineering has now enabled them to strip from the vaccine those components thought to react with heart tissue. The first phase of the trials will involve adults only; plans call for eventually including children.
Q&A

Doctors disagree on what causes this phenomenon, which appears to be hereditary and goes by three clinical names: "photosternutatory reflex," "autosomal dominant compelling helio-ophthalmic outburst" (ACHOO), and, most commonly, "photic sneeze reflex." According to one theory, light stimulates the nerves in the face, which in turn irritate the mucous membranes, resulting in a sneeze; a second theory holds that the optic nerve irritates the mucous membranes. Up to a third of the population is thought to be afflicted. Military researchers, worried about the implications for combat pilots, have sought remedies, but to no avail. After subjecting pilots wearing military, designer, and ordinary sunglasses and goggles to different wavelengths and intensities of light, the researchers were able to conclude only that "the best defense appears to be education and identification of those pilots with the sneezer trait."

Environment

The Skies
October 5: Venus, the waning crescent Moon, and the bright star Regulus make a tight triangle in the east just before dawn. Venus has just passed its maximum brilliance for the year. 23: Jupiter is at opposition -- it rises as the sun sets and stays in the sky all night long. It is also at its brightest since 1987. 24: Full Moon, also known this month as the Hunter's Moon and the Moon of the Freezing Water. 31: At 2:00 A.M., Daylight Saving Time gives way to Standard Time. Turn clocks back one hour.
25 Years Ago
Edwin Newman, writing in the October, 1974, issue of The Atlantic Monthly: "[The expression] eyeball-to-eyeball, though it came close to burlesque even at the beginning (for example, when hard-nosed private eyes are private-eyeball-to-private-eyeball, does an eye or nose prevail?), was once a fairly graphic phrase. Because of overuse, it has been devalued. American journalism has a way of seeing to that, of fastening on words and sucking them dry. Controversial is such a word, because it is applied to almost every issue that arises in politics, and because reporters feel obliged to tell us that issues that are resolved in the Senate by votes of fifty-one to forty-nine are controversial. Again, as anyone can discern from book jackets, scarcely a book appears that is not controversial, even when it is also witty, warm, and wise."
