The Gold Of The Andes
This video clip is a short film about a journey to source one of the most luxurious materials in the world. The Incas believed the Vicuña animals were  rewarded with a coat of pure gold in return for giving life to their civilization. They called it “The Gold Of The Andes”. (07:17)

Energy resources: Wave energy
The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. This free course, Energy resourc

2.797J Molecular, Cellular, and Tissue Biomechanics (MIT)
This course develops and applies scaling laws and the methods of continuum mechanics to biomechanical phenomena over a range of length scales. Topics include structure of tissues and the molecular basis for macroscopic properties; chemical and electrical effects on mechanical behavior; cell mechanics, motility and adhesion; biomembranes; biomolecular mechanics and molecular motors. The class also examines experimental methods for probing structures at the tissue, cellular, and molecular levels.

Hurricanes: New Tools for Predicting
Hurricane Katrina, which struck New Orleans and other Gulf Coast communities on August 29, 2005, provided the worst kind of reminder of the importance of accurate hurricane prediction — and of heeding those predictions. This video segment adapted from NOVA scienceNOW a year before Katrina struck, describes the current state of research into what causes hurricanes and how scientists are now able to "see" inside the storms in their ongoing efforts to more accurately predict both the path and

7.342 G-Protein Coupled Receptors: Vision and Disease (MIT)
How do we communicate with the outside world? How are our senses of vision, smell, taste and pain controlled at the cellular and molecular levels? What causes medical conditions like allergies, hypertension, depression, obesity and various central nervous system disorders? G-protein coupled receptors (GPCRs) provide a major part of the answer to all of these questions. GPCRs constitute the largest family of cell-surface receptors and in humans are encoded by more than 1,000 genes. GPCRs convert

6.2.1 The need for a reference frame for describing the Universe

The speed of the Earth in its orbit round the Sun is 29.8 km s−1, in a heliocentric frame. But to specify the velocity vector, it is not sufficient to specify the Sun as the origin of the coordinate system; fixed directions must also be identified.

4.1.1 Summary of Section 4

The integration of physiological and molecular responses links an environmental signal to a physiological response. Heat-shock proteins (Hsps) are chaperone proteins that maintain the structure and function of proteins in cells exposed to high temperatures. The initial response of cells to high temperatures is rapid transcription of heat-shock genes, e.g. Hsp70, which is possible because Hsp70 is normally partly transcribed by RNA polymerase II. Resumption of transcription requi

2.1 Introduction

Every receptor has to be able to recognize its particular ligand in a specific manner, and become activated by it in such a way that it transmits the signal to the cell. We shall deal with receptor specificity and activation mechanisms. Then we shall see how the same principles of specificity and activation also apply to intracellular receptors.
