20.440 Analysis of Biological Networks (BE.440) (MIT)
This class analyzes complex biological processes from the molecular, cellular, extracellular, and organ levels of hierarchy. Emphasis is placed on the basic biochemical and biophysical principles that govern these processes. Examples of processes to be studied include chemotaxis, the fixation of nitrogen into organic biological molecules, growth factor and hormone mediated signaling cascades, and signaling cascades leading to cell death in response to DNA damage. In each case, the availability o
Fe, C 1.0 (wt%), hypereutectoid alloy
This secondary electron SEM image shows the cementite delineating prior austenite grain boundaries with a thin layer. The amount of proeutectoid phase is very low, with the majority of the area being taken by the pearlite eutectoid. Again each pearlite cell has a different orientation with the ferrite phase being selectively etched.

7.341 Brightening up Life: Harnessing the Power of Fluorescence Imaging to Observe Biology in Action
One summer in the 1960s a young Japanese researcher, with the help of a few high school students, chopped up ten thousand jellyfish. As a by-product of this harvest, they isolated a green fluorescent protein (GFP). Since then, GFP has triggered a revolution in our understanding of gene expression and signaling in live cells. In this seminar, we will examine how this small protein generates fluorescence, i.e. absorbs light of one wavelength and emits light of a longer wavelength. We will discuss
Cold War: Red China - part 4/5

The Young People's Chorus of New York City
The Young People's Chorus was founded by conductor Francisco Nuñez to celebrate the diversity and musical richness of his hometown, New York City. In this performance video from From the Top at Carnegie Hall, listen to a performance of Panta Rhei (Greek for "all things are in flux") by another New Yorker, composer Jim Papoulis. Many of the musical elements—a driving rhythm, syncopation, atonality, and surprising percussion—contribute to the sense of change and movement.
