The Sun — Earth's main source of energy — appears to shine at a constant rate. However, the Sun's magnetic field is actually constantly changing, and this affects its energy output. These variations cause effects that extend throughout the solar system. In this video segment adapted from NOVA, learn about some of the effects that solar activity may have on Earth. Closed captioning included. Run time 02:20.

Opportunities in Building More Sustainable Supply Chains
When a global corporation implements sustainability standards, it pays to work closely with supply chains, as these panelists attest.
From his research, Richard M. Locke knows that the traditional methods of achieving decent labor conditions don’t work well. When Locke examined years of records gathered by Nike a
The Second Law and Energy
This Nobel Prize-winning scientist admits to staying up late the night before his talk to bone up on thermodynamics. He puts his research to good use, discussing the history and application of the laws of thermodynamics, which have served as “the scientific foundation of how we harness energy, and the basis of the industrial r

2 River flow
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there area areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enought water to support the currently population adequately. Decisions will have to be made on the best way to use water in a
Just as digital technology has expanded the means of producing media, so has it increased the geographic range new media may travel. Locally generated content can zip around the world in a heartbeat. But, says moderator Henry Jenkins, “as a society we’re in a contradictory state in terms of having greater access to glob

3.1.1 Stellar masses and stellar evolution Measured stellar masses range from about 0.08M⊙ to about 50M⊙, with stars of lower mass being more common. Stars lose a rather small fraction of their masses during much of their lifetimes, but much larger fractions when they shed planetary nebulae, or when they undergo supernova explosions. When stellar masses are placed on an H-R diagram, and coupled with observations of mass loss,
