...addition, the SAM6 is equipped with a heat sensor that can guide it to the aircraft's hot jet exhaust pipe. Finally, in its beam-riding mode, the SAM6 can be directed by its operator, who keeps the aiming dot of an electronic gun sight on the attacking aircraft. That is all it takes to send the missile accurately along a radar beam to the target. To make matters even worse for the enemy, the frequency of the missile's radar systems can be changed quickly, making it difficult to jam or confuse them with electronic countermeasures...
...post-operative pain, often has to forgo even the satisfaction of complaining; any talking may irritate his throat and delay his recovery. Now doctors at Boston University Medical Center are finding a way around both problems. They have found that a carbon-dioxide laser, which produces a high-intensity beam of invisible infra-red light, can quickly remove many polyps, cysts and cancers from vocal cords. Moreover, the laser operations, which are more precise and efficient than conventional surgery or freezing with cryoprobes, have proved remarkably free of discomfort for the patient...
Brief Exposure. Though the laser is a complex mechanism, its application is relatively simple. Inserting a tube that gives them line-of-sight access to the vocal cords, the surgeons aim the laser through the passage by means of a binocular microscope and a tiny beam of normal white light. After zeroing in on the target growth, the surgeon then steps on a foot pedal that opens a shutter on the laser and allows the infra-red laser beam to strike the diseased tissue for as little as one-tenth or as much as one-half of a second...

...Some YEWESSERS dwell in apartments, where they live on either side of a flimsy medicine cabinet. All others live in white split-level houses. The males are cranky in the morning and astonished when the coffee is not bitter or the breakfast is palatable. Then they beam and demand to know the name of the product, which they repeat nine times. The wives then proceed to their day, which consists of eight hours of unmitigated jealousy and fear. The jealousy is exhibited at wash time. During this period they stare enviously at their neighbor's laundry, which is always...
