...into brilliant displays of red, orange and yellow. Now two atmospheric scientists at NASA'S Langley Research Center think that they have found the cause of the heavenly pyrotechnics. Writing in Applied Optics, Physicists Michael McCormick and William Fuller Jr. report that their surveys of the stratosphere with laser beams have revealed two new layers of dust at altitudes of 10 and 12.5 miles. That extra dust would enhance a well-known phenomenon: when the sun is low in the sky, its rays travel through more of the atmosphere and thus encounter more dust particles. The particles, in turn...
...1920s, electronic engineers have been looking for a simpler, less fragile and more economical device for displaying images transmitted over the air waves. Now scientists at the Westinghouse Research Laboratories in Pittsburgh think that they may have found a way. At this month's electro-optics and international laser exhibition in San Francisco, they displayed the prototype of a flat-screen TV system that is less than one-eighth of an inch thick and may some day be hung on a wall like a pane of plate glass in an ordinary picture frame...

...higher standards can have practical benefits. Last week, for instance, President Ford signed a long overdue campaign-financing reform bill. The voters of California have approved a stringent anticorruption measure. But there is also a tendency to condemn prematurely and to burn today's leaders with the laser of hindsight. It is a particularly painful period both for public leaders and for a people in need of leaders who merit confidence...
Lately scientists have been turning to a more efficient tool for creating fusion: the laser. By heating a tiny pellet of deuterium or tritium with a powerful pulse of laser light, they cause the explosive evaporation of the pellet's surface. As the material sprays off, the rest of the pellet implodes. The hydrogen nuclei are thus forced together. As early as 1968, a team of Soviet researchers under Physicist Nikolai Basov, a Nobel laureate, reported that they had used lasers to ignite a brief but clearly detectable fusion reaction. Since then, their experiments have been repeated-and improved...
