人们都说，母亲是孩子生命中不可或缺的一部分，她们赋予了孩子们生命，也在孩子的成长给他们以无微不至的爱与关怀,而父亲，往往是以一个严厉的形象存在，往往是孩子幼年时期的偶像。那么，在生物学意义上，父亲这个角色会对孩子的成长起到什么作用呢？他们仅仅是母亲的替补？还是有其真正意义的所在？鉴于父亲节即将到来，让我们一起来认识一下，父亲对于孩子们成长的重大意义吧~！

“你是电视的产物。” 　　“电视通过商业主义教导的是物质消费。” 　　如今举世闻名的雕塑家理查德·塞拉早年曾涉足当时的新媒体电影和视频。 　　他与卡洛塔·费伊·斯库尔曼合作，创作了六分钟的视频《电视传递人》，批判电视大众媒体和资本主义社会。 　　在当时典型的超市或电梯音乐的伴奏下，蓝色背景上电子生成的黄色文字带从下到上横跨屏幕。观众面对的是批判性言论，迫使他们反思自己对电视大众媒体的消费主义行为。伪装成娱乐的商业主义的影响显而易见：“你被消费了。”这些批判性论点具有挑衅性，与欢快的器乐形成鲜明对比，强调了矛盾的情况。事实上，这部视频作品实际上在 1973 年在电视上播出过——两位艺术家购买了播出时间。 　　影像的低成本美学也让人联想到当时常见的观众信息公告：受到批评的不是电视节目的内容，而是电视广播公司的策略被解构。

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.
