Production in the Innovation Economy (PIE): A New MIT Study on the Current State and Future of U.S.

The Production in the Innovation Economy (PIE) project brings together leading MIT faculty from a variety of disciplines to look at the present state and future of U.S. manufacturing. The study's overarching goal is to shed light on how America's great strengths in innovation can be scaled up into new productive capabilities. This talk will present some preliminary findings from PIE and focus on examples of promising manufacturing models based on over 150 company interviews to date.

7.2 The eubacterial chromosome

Some of the diverse roles of chromatin components can be illustrated by examining the E. coli chromosome. Like most prokaryotes, E. coli has a single chromosome consisting of a single double-stranded circular DNA molecule. There is no nucleus present, but the E. coli DNA is within a discrete entity in the cytoplasm called the nucleoid. The nucleoid contains a multitude of proteins and is in close proximity to the ribosomes, where translation occurs. In addition to

6.5 Conformational changes upon protein–DNA interactions

During binding, both the protein and the DNA can alter their conformation. In the case of proteins, this conformational change can involve small changes in side-chain location, but can also involve local refolding. These changes upon binding of specific DNA sequences serve to facilitate the interaction and also to enhance the binding of other proteins, such as when dimerization of two proteins occurs at a single recognition site. Changes such as these can be the basis of cooperative binding e

Quadruplex structures

The ends of linear chromosomes are protected from potential damage by special elements called telomeres. In many organisms, telomeres consist of long stretches of DNA that contain many thousands of copies of G-rich repeat sequences. They are easily detected by FISH (Subsection 2.4), as shown in the case of human telomeres in Fig

4.2 Iron transport

It is obvious that iron must be transported around the human body. Firstly, it must be transported from the food in the gut to the places where it is required. Mostly, iron is required in the bone marrow, where red blood cells are formed. Red blood cells have a finite lifetime of about only four months, and old cells are destroyed, usually in the spleen. Iron from the destruction of these cells is then transported from the spleen back to the bone marrow to be recycled.

Iron cannot be tr

3.5 A new life

There is a common belief that life begins at the moment of conception, i.e. when a sperm fuses with an egg. This is a step forward from past years, when life was alleged to start at the time of ‘quickening’, i.e. when a woman could feel her fetus moving inside her. However, both these opinions suffer from an underlying falsehood: that life ‘begins’ at all. Life is a continuum; gametes are produced by living parents, and fuse to produce new living individuals, but unfused gametes are n

3.2.1 Axes

A graph is made using two different scales or axes, forming a right angle. The horizontal axis (x-axis) is used to represent the variable that changes in a consistent way, such as time, or in a way that you can control. The vertical axis (y-axis) is used to represent a variable that you measure but may not be able to control directly, such as a patient's temperature.

Each axis should be carefully labelled to indicate what it represents. To plot a graph, you put a mark at the poin

1.7.3 Framing an appropriate and useful research question

At the heart of any research is the research question. The quality of output hinges on the quality of the question: why it is asked, how it is asked, how it relates to other questions and knowledge, and what might constitute an answer. Hence, one key skill is demonstration of the ability to develop a well-formulated question. The examiner will be looking for evidence of:

1.4.8: Graphical conversions: summing up

This section started by looking at conversion graphs which were straight lines passing through the origin of the graph. The intercept in those cases was zero, and only one number – the gradient – was needed to describe the relationship between the quantities plotted on the horizontal and vertical axes. In the more general case, the graph is still a straight line with a constant gradient, but the line no longer goes through the origin. An extra number – the intercept – is used to pin t

1.4.4 Graphical conversions: How is the constant of proportionality represented on a graph?

One of the main features of a straight-line graph is that the line has a constant slope. The gradient of the slope is numerically equal to the constant of proportionality. For a 1 : 25 000 map, the constant of proportionality between ground distances in kilometres and map distances in centimetres is 0.25 km per cm. So the gradient of the corresponding graph is 0.25.

A similar relationship holds for a 1 : 50 000 map. In this case, 1 cm on the map corresponds to 0.5 km on the ground, so t

4.3 Graphical conversions: How do you use the graph?

Look at Figure 9. Start with the map distance on the horizontal scale, move vertically up until you reach the line, then move horizontally until you reach the vertical axis. The number at that point will give you the corresponding ground distance in kilometres.
