Mark Schnitzer is assistant professor of Biology and Applied Physics at Stanford University. His group is developing fluorescence optical imaging techniques, such as microendoscopy techniques involving fiberand micro-optics, for studying populations of individual neurons in live animals over both short and long time scales. He is applying these techniques to studies of learning and memory as we...

Coronary stents were developed to overcome the two main limitations of balloon angioplasty, acute occlusion and long-term restenosis. Coronary stents can tack back intimal flaps and seal the dissected vessel wall, thereby treating acute or threatened vessel closure after unsuccessful balloon angioplasty. After successful balloon angioplasty, stents can prevent late vessel remodeling (chronic ve...

Critical intellectuals were traditionally those who utilized their skills of speaking and writing to denounce injustices and abuses of power, and to fight for truth, justice, progress, and other positive values. In the words of Jean-Paul Sartre (1974: 285), "the duty of the intellectual is to denounce injustice wherever it occurs." The modern critical intellectual's field of action was what Hab...

Visualization of cellular and molecular processes is an indispensable tool for cell biologists, and innovations in microscopy methods unfailingly lead to new biological discoveries. Today, light micros-copy (LM) provides ever-higher spatial and temporal resolution and visualization of biological process over enormous ranges. Electron microscopy (EM) is moving into the atomic resolution regime a...
