15.974 Leadership Lab (MIT)
This five-day interactive and experiential workshop focuses on how leaders lead innovations that both promote social responsibility and produce business success. The workshop is organized around three main parts: observation, sense-making, and creating. During the observation phase, students spend a full day inside the Boston office of the design company IDEO and visit some of the most interesting proven innovators in corporate social responsibility such as Ben & Jerry’s, KLD, MBDC, Pl

Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;

This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

In this unit we explore how proteins are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this unit are crucial to understanding how proteins perform their various roles.

Education in the wild: contextual and location-based mobile learning in action. A report from the ST
A new report has been published by the LSRI/University of Nottingham that gives an essential overview of research into location-based contextual mobile learning primarily across Europe, edited by Elizabeth Brown. The report follows on from a 2-day workshop funded by the STELLAR Network of Excellence as part of their 2009 Alpine Rendez-Vous workshop series. Contributors have provided examples of innovative and exciting research projects and practical applications for mobile learning in a location
7.90J Computational Functional Genomics (MIT)
The course focuses on casting contemporary problems in systems biology and functional genomics in computational terms and providing appropriate tools and methods to solve them. Topics include genome structure and function, transcriptional regulation, and stem cell biology in particular; measurement technologies such as microarrays (expression, protein-DNA interactions, chromatin structure); statistical data analysis, predictive and causal inference, and experiment design. The emphasis is on coup

HST.721 The Peripheral Auditory System (MIT)
In this course, experimental approaches to the study of hearing and deafness are presented through lectures, laboratory exercises and discussions of the primary literature on the auditory periphery. Topics include inner-ear development, functional anatomy of the inner ear, cochlear mechanics and micromechanics, mechano-electric transduction by hair cells, outer hair cells' electromotility and the cochlear amplifier, otoacoustic emissions, synaptic transmission, stimulus coding in auditory nerve
Construction d'une base de connaissances et d'une banque de ressources pour le domaine du téléappr
This article sets the foundation for the development of a knowledge base and a resource (learning object) repository in the domain of telelearning, enabling researchers to reference resources in this domain using standard specifications based on domain ontology and to integrate them according to a set of research or teaching activities. The resources are referenced with metadata based on domain ontology and their search is guided by use cases describing activities where these resources are used
Two-Cell Battery
In this hands-on activity, students build their own two-cell battery. They also determine which electrolyte solution is best suited for making a battery.
Cell Signalling
A chapter which describes the mechanisms of signal transduction in a eukaryotic cell, including the activation of G-proteins and kinase cascades (49 figures). The unit is intended as ~10hrs study at level 2/3. It also provides background reading for the experimental investigation 'Investigating intracellular signalling pathways' (http://open.jorum.ac.uk/xmlui/handle/123456789/1581).
Introduction to Glycolysis
Living cells can process certain sugar molecules, rearranging their atoms and this process can supply energy to the cell to power growth and other functions. This process is called glycolysis. Glycolysis evolved billions of years ago when there was no oxygen in the earth's atmosphere and it was therefore impossible for cells to gain energy from the oxidation of sugar molecules using oxygen. Later when oxygen was produced as a byproduct of photosynthesis cells evolved to utilise oxygen to oxidise
7.342 Cancer Biology: From Basic Research to the Clinic (MIT)
This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting.
In 1971, President Nixon declared the "War on Cancer," but after three decades the war is still raging. How much progress have we made toward winning the war and what are we doing to improve the fight? Unde
Open-celled aluminium foam
Although the processing route is complicated and the product expensive, there is a high degree of control over the cell structure of such foams and the final shape can be controlled to meet near-net-shape requirements.

Topics: development of the nervous system and its connections, cell biology or neurons, neurotransmitters and synaptic transmission, sensory systems of the brain, the neuro-endocrine system, the motor system, higher cortical functions, behavioral and cellular analyses of learning and memory. First half of an intensive two-term survey of brain and behavioral s
Virtual yeast cell
This rich learning object is used to introduce yeast cytology to students taking Module D24BS3 Brewery Yeast Management as part of the MSc in Brewing Science. The virtual cell permits the students to understand structure and function of yeast organelles.
FOAMCARP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. Calcium carbonate is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a fine and relatively uniform cell structure.
High magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, and some remnants of collapsed cell walls can be seen at the cell edges.
