An Introduction to DNA: Spectrophotometry, Degradation, and the 'Frankengel' Experiment
In this laboratory students perform three exercises as an introduction to the basics of handling and analyzing DNA. In the first, they expose circular plasmid, linear phage, and high molecular weight genomic DNA samples to a variety of physical, thermal, chemical, and enzymatic conditions that might be expected to affect DNA integrity. The DNA's are analyzed by electrophoresis on a group agarose gel. In the second, they pour and reconstruct a "Frankengel" (a gel containing sections with three di

When Everything Looks Like a Nail: Graph Models of the Internet
The general appeal of abstracting real-world networks to simple graphs is understandable and has been partly responsible for fueling the new field of "network science". However, as the Internet application has demonstrated, such abstractions that ignore much of what engineers consider as critical come at a price. For example, they can lead to the study of graph models that have little in common with the real-world networks that motivated these models in the first place. In turn, they tend to foc

To What Extent Do Economic Conditions Determine the Outcome of Presidential Elections?
Students consider how economic performance is evaluated and are introduced to four major indicators of macroeconomic performance: growth rate of real income, unemployment rate, inflation rate, misery index. They complete a worksheet comparing changes in these indicators with the outcomes of U.S. presidential elections from 1960 to 1992 and examine the influence of economic conditions on the likelihood of the incumbent party winning an election.

"A Person Like Me, Oppress'd By Dame Fortune, Need Not Care Where He Goes": The "Infortunate" Willia
Many travelers made their way to Philadelphia and the Mid-Atlantic colonies in the eighteenth century in search of economic opportunity, but not all experienced the fabulous success of Benjamin Franklin. William Moraley, born in 1699 into a modest artisanal family, was more typical. Economic cycles were often critical in determining migration patterns; approximately 73,000 people left for the British colonies in the1730s, twice the average of earlier in the century (17,000 arrived in Philadelphi

Otis MFA Graphic Design Guest Lecture: Walead Beshty
Graduate Graphic Design Presents a lecture by Artist Walead Beshty, who has long used photography as a tool to explore the social and political conditions of our material culture. More recently, the material conditions of photography itself have spurred his continuing investigations of the gap between the physical world and the image world, and the way this rupture is instrumentalized by ideologies that seek to infiltrate the processes through which we produce meaning.From his early projects, li

2 Growth and development: the big picture

The scale of the problem facing the human zygote is vast. The zygote, the single cell resulting from the fusion of a sperm and an ovum, is about the size of a full stop on a nomal printed page, yet within 9 months it has become a 3 kg, 50 cm long baby. The single cell has made millions of other cells; 1011 (i.e. 100 000 000 000) neurons in the brain alone. Not only is there this vast and rapid increase in the number of cells (some calculations put the peak figure at 250 000 new
