Nanoelectronics 101
Semiconductor device technology has transformed our world by making possible supercomputers, personal computers, cell phones, ipods, and much more that we now take for granted. Moore's Law observes that the number of transistors (the basic building blocks of electronic systems) per electronic chip doubles each technology generation. This doubling of transistor density each technology generation has continued since Gordon Moore, one of the co-founders of Intel, made his observation in 1965. It ha

The Discovery of Penicillin
In this video segment adapted from A Science Odyssey, learn what led British researcher Alexander Fleming to the chance discovery of antibacterial properties of a mold extract he later named penicillin. After treating World War I battlefield casualties, Fleming began searching for compounds that would ward off infections in humans. Returning from vacation in the summer of 1928, he noticed that mold was partly covering one of the agar plates in which he had been growing bacteria, and that the mol
