The life of a cell

This amaving video from Harvard shows the inner life of a cell.

Thoughts from Harvard professors on ethics in the humanities and science (with links to lectures):

• Michael Sandel: 'We must bring back into philosophy an older set of questions - about the moral status of nature and about the proper stance of human beings toward the 'given' world. To what extent should we aspire to unlimited dominion over the natural world, even to the point of remaking our own nature?'
  
• Steven Hyman: Questions about the ethics of ... biomedical issues 'are questions about our very humanity.'
