“Phobias have often been a subject of ridicule. But ‘funny’ is one thing they are not.”—Jerilyn Ross, director of a treatment center for anxiety disordersTHE word “phobia” refers to an intense, unrealistic fear of an object, an event, or a feeling. But a definition alone cannot convey the terror and loneliness that mark this condition. Raeann Dumont, who has treated phobias for more than two decades, notes: “Phobic people may avoid so many situations that they become housebound, or they may live with constant, unrelenting anxiety, or they may relieve their anxiety with alcohol, which may cause additional problems.”

Treatment Obstacles
In time, the large pharmaceutical companies started to offer AIDS drugs at much lower prices to developing countries in need. It was hoped that in this way many more people would be able to make use of the drugs. However, there are major obstacles to overcome to make such drugs readily available in developing lands. One of these is the cost. Even at drastically reduced prices, the drugs are still far too expensive for the majority of the people who need them.
Another problem is that the drugs are not easy to administer. Many pills must be taken daily, at specified times. If they are not taken correctly or if the medication routine is interrupted, this could lead to the development of drug-resistant strains of HIV. It is difficult to ensure adherence to correct dosages in African conditions, where there may be little food, a low supply of clean drinking water, and few medical facilities.

Comet Crash !
For a week in July 1994, the collisions of about 20 fragments of the comet Shoemaker-Levy 9 into the planet Jupiter captured the attention of stargazers around the world. Comet watchers marveled, since the display turned out to be, as one astronomer put it, “the celestial drama of the century.” Why did this event far exceed expectations?

Those Awesome Baby Brains
They are awesome from their beginning. Three weeks after conception, they start out with 125,000 cells and thereafter increase in spurts of 250,000 cells a minute. Each little brain continues its explosive growth until at birth its cells number some 100,000,000,000—as many as there are stars in the Milky Way!
But months before that, while still in the womb, baby’s brain has gone into operation. It is registering perceptions from its watery environment. It hears, tastes, senses light, reacts to touch, learns, and remembers. The mother’s emotions can affect it. Gentle words or soft music calms it. Angry speech or rock music agitates it. The mother’s rhythmic heartbeat soothes it. But if fear sets her heart racing, soon baby’s heart beats twice as fast. A distressed mother transmits anxiety to the babe in her womb. A tranquil mother carries a peaceful baby. A joyful mother may make the babe in her womb jump for joy. All of this and more keeps baby’s brain busy. Even in the womb it is awesome.

The Power of Spider Silk
It is lighter than cotton, yet ounce for ounce it is stronger than steel. For decades scientists have studied the silk produced by orb-weaving spiders. Dragline silk—the strongest of the seven silks these spiders can spin—has attracted the most attention. It is tougher and more waterproof than silkworm strands, which are commonly used in clothing.

Smoking Deaths Helpful to the Economy?
“Philip Morris Cos. officials in the Czech Republic have been distributing an economic analysis concluding that . . . smokers’ early deaths help offset medical expenses,” says The Wall Street Journal. “The report, commissioned by the cigarette maker . . . , totes up smoking’s ‘positive effects’ on national finances, including revenue from excise and other taxes on cigarettes and ‘health-care cost savings due to early mortality.’” The article adds: “Weighing the costs and benefits, the report concludes that in 1999 the government had a net gain of 5.82 billion koruna ($147.1 million) from smoking.”
