Most of all, Murphy dreaded the "dragon's tail effect"-that frightening phenomenon in which a mere twitch at the tail's base can be come a paroxysm by the time it reaches the tip. By lingering an hour over schedule in one place, the Humphrey cavalcade can make a shambles of a whole day's tight schedule...
...most formidably inaccessible places is the labyrinth of arteries inside the brain. But at the latest meeting of the American Roentgen Ray Society, Dr. Sadek K. Hilal demonstrated a catheter with a magnetic tip that "swims" through small and tortuous arteries and can be guided to the exact spot that the radiologist or neurologist wants to reach...
...Earlier catheters were often stopped by friction and could not always be guided into the desired path at a junction or around sharp curves. The new model, developed in research at Manhattan's Columbia-Presbyterian Medical Center and at the Weizmann Institute in Israel, has a magnetic tip. This can be made to oscillate in different directions under the control of an external magnet on alternating current. As the tip vibrates, it pulls clear of the artery's walls, leaving them undamaged, and "swims" forward. When the magnet is powered by direct current, it helps to steer...

The trouble was not serious enough to affect the mission. Astronaut Eisele, 38, an Air Force major also making his first space mission, reported radio interference that sounded like a commercial. "I', getting a hot tip on some hostpital-insurance plan...
