Control of Surface Exudation by Slugs
This experiment is meant to study water regulation in mollusks by observing the reaction of slugs, which are closely related to mollusks, to excess water.
Symba: a Framework to Support Collective Activities in an Educational Context
Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates an organizational level and an activity level. The organization level allows students to organi
Assembly of Proteins in Membranes II from the course General Biochemistry and Molecular Biology
General Biochemistry and Molecular Biology - Fall 2006. This course covers molecular biology of prokaryotic and eukaryotic cells and their viruses. Mechanisms of DNA replication, transcription, translation. Structure of genes and chromosomes. Regulation of gene expression. Biochemical processes and principles in membrane structure and function, intracellular trafficking and subcellular compartmentation, cytoskeletal architecture, nucleocytoplasmic transport, signal transduction mechanisms, and c
Gas Particles in Motion
We are constantly being exposed to the behavior of gases. Each time we pump up a tire, blow up a balloon, use a spray can, or experience the cooling of gases as they escape from a gas storage container, we are reminded of how gases behave with changes in temperature, volume, pressure, or number of particles. In an astronomical scale, we know that star formation involves contraction of gas clouds to produce dense, high-pressure cores capable of fusion reactions. These labs will help your students
Human Genome Education
Anyone with a computer and an Internet connection can now explore the draft sequence of the human genome. How can molecular biologists capitalize on these data riches, and what are the advantages of using the assembled draft sequence? This website aims to jump-start those who want make use of this information, but are not sure where or how to start.

Bad blood - A case study of the Tuskegee syphilis project
Syphilis is a venereal disease spread during sexual intercourse. It can also be passed from mother to child during pregnancy. It is caused by a corkscrew-shaped bacterium called a spirochete, Treponema pallidum. This microscopic organism resides in many organs of the body but causes sores or ulcers (called chancres) to appear on the skin of the penis, vagina, mouth, and occasionally in the rectum, or on the tongue, lips, or breast. During sex the bacteria leave the sores of one person and enter
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
The Global Emerging Market and its role in a time of crisis
The global emerging market, which did not exist 25 years ago, now has an input of about 50% into the world economy and attracts more than 40% of foreign direct investment. The economic dynamic of emerging market countries has a strong and positive influence on the world economy and, as such, has to be re-evaluated during this development of a new global order. Dr. Vladimir Kvint, economist and strategist, is the President of the International Academy of Emerging Markets and Chairman of the Russi
Seizing the Opportunity of the Cloud: the Next Wave of Business Growth
The pervasive nature of technology and the ever increasing pace of development are rapidly changing the way we work, live and play. These changes bring enormous opportunity for individuals, organisations and society. For more than three decades, Microsoft, and current CEO Steve Ballmer, have played a vital role in leading a technology industry that has transformed the world of business in dramatic fashion. In one of the opening public lectures of the LSE term, Ballmer will discuss what's next,
A conversation with James Caan
A recession can uncover some great entrepreneurial talent and surprising opportunities. The speakers will explore how we can make the UK more entrepreneurial, what are the key components in creating a successful business, the major pitfalls and what are the emerging sectors for people to capitalise on. They will also debate whether an entrepreneurship can be taught or is a part of genetic make up. James Caan is one of the UK's most successful and dynamic entrepreneurs. He is now CEO of private e
7.340 Regenerative Medicine: from Bench to Bedside (MIT)
Regenerative medicine involves the repair and regeneration of tissues for therapeutic purposes, such as replacing bone marrow in leukemia, cartilage in osteoarthritis or cells of the heart after a heart attack. In this course, we will explore basic mechanisms of how cells differentiate into specific tissues in response to a variety of biologic signaling molecules. We will discuss the use of such factors for in vitro tissue production. We will also study the cellular mechanisms involved in the cl
7.345 Vascular Development in Life, Disease and Cancer Medicine (MIT)
The growth of blood vessels, a process known as angiogenesis, is one of the earliest events in mammalian development and is regulated by a sensitive interplay of growth factors and other molecules. In this course, we will discuss the key molecular regulators of blood vessel development as well as the techniques and experimental systems that have been utilized by vascular biologists. We will also examine the success of several anti-angiogenic treatments that have been approved by the Food and Dru
5.111 Principles of Chemical Science (MIT)
Introduction to chemistry, with emphasis on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. Introduction to the chemistry of biological, inorganic, and organic molecules.
Stem Cells: Programming and Personalized Medicine
After years of relentless lab work, rising and falling expectations, and the challenge of a sometimes hostile public, Rudolf Jaenisch says, “The scenario that looked like a fantasy … has come closer to reality. We can study complex human diseases in a Petri dish and potentially contribute to therapy.” In this l
An introduction to biological systematics
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
Keynote Presentation: Academic Perspectives
Very simply stated, systems biology attempts to “capture the dynamic nature of living systems.” To accomplish this, says Hood, you “have to bring together the flavors of biology, chemistry, computer science, engineering and physics,” among others. It’s a vast area to tackle. But with tools like the internet and digital
Bioengineering at MIT: Building Bridges Between the Sciences, Engineering and Health Care (Part Two
Glycomics, the study of sugars’ role in living systems, is a relative newcomer to the revolution in molecular biology. In fact, Ram Sasisekharan remembers how colleagues told him “not to work on carbohydrates -- that it was useless.” But his research has shown that glycans, observed as long chains or intricat
Nanotechnology and the Study of Human Diseases
Subra Suresh fleshes out the promise of nanotechnology, at least in regard to our understanding of disease. His talk, which focuses on malaria and its impact on red blood cells, demonstrates how the fields of engineering, biology and medicine are converging.
To function properly, he explains, a red blood cel
