This course encompasses the study of eating as it affects the health and well-being of every human. Topics include taste preferences, food aversions, the regulation of hunger and satiety, food as comfort and friendship, eating as social ritual, and social norms of blame for food problems. The politics of food discusses issues such as sustainable agriculture, organic farming, genetically modified foods, nutrition policy, and the influence of food and agriculture industries. Also examined are problems such as malnutrition, eating disorders, and the global obesity epidemic; the impact of food advertising aimed at children; poverty and food; and how each individual’s eating is affected by the modern environment.

胎儿干细胞，取自未出生就被遗弃的“被堕”胎儿，全世界每年都有四千万双还未睁开就永远闭上的眼睛，堕胎反对者称之为“谋杀”；胎儿干细胞，有治愈多种疾病的奇效，从肌肉、血管硬化症到自闭症，让卧床不起的病人重新站起，让“星星的孩子”回到地球，创造了无数个现代医学的奇迹。胎儿干细胞，每一个光彩照人的奇迹背后都有一出鲜血淋漓的悲剧，它究竟是天选之物还是人类原罪的“试金石”，我们不得而知。本片将聚焦共担诟病和美誉的“灰色技术”——胎儿干细胞疗法，力求在50分钟里还原争议背后的故事，给世界多一个角度的思考。

共三集：1.隐匿的王道 2.生命中的化合 3.生命的火花 　　The Cell In a three-part series, Dr Adam Rutherford tells the extraordinary story of the scientific quest to discover the secrets of the cell and of life itself. Every living thing is made of cells, microscopic building blocks of almost unimaginable power and complexity. “I am normally not a lover of scientific docu’s but this one I found I had to watch all 3 parts back to back”. 　　The Hidden Kingdom 　　The first part explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realize that there was, literally, more to life than meets the eye. 　　The Chemistry of Life 　　This episode explores how scientists delved ever deeper into the world of the cell, seeking to reveal the magic ingredient that can spark a bundle of chemicals into life. Their discoveries have brought us to the brink of being able to create life for ourselves. 　　The Spark of Life 　　The final part reveals how our knowledge of cells has brought us to the brink of one of the most important moments in history. Scientists are close to repeating what has happened only once in four billion years - the creation of a new life form.
