探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit15 The work of these scientists is at last throwing a spotlight onto the mysterious hidden world of epigenetics. They appear to show that the lives of our ancestors have a capaci...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit14 The impact of a famine being captured by the genes in the eggs and sperm, and a memory of this event was being carried forward to affect the grandchildren, generations later....
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit13 They discovered that when a famine was able to trigger an effect was different for the grandmother than the grandfather. The grandmother appeared susceptible while she herself...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit12 Olov Bygren was looking to see if poor nutrition had an effect on health when he stumbled on something curious. It appeared that a famine could affect people almost 100 years...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit11 But could this effect be transmitted to their offspring? They found nearly 200 women of whom a number had actually been in the Twin Towers. About half of them developed post-t...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit10 Our studies had really convinced me that it were the later experiences of the child as the child was growing up bombarded with years and years of, em, symptoms from the parent...

探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit09 The email was sent by Olov Bygren. He was studying the population records of an obscure town in northern Sweden, Overkalix. What made these records unique was their detail. Th...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit07 After we had seen how relatively easy it was to change the switches in mouse embryos, we thought that perhaps the same could be true of human embryos. In IVF, you also have th...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit06 If inheritance was not just about DNA, if these gene switches were so important, just what could turn them on or off? Stephanie and Emend Mullins have two children, Karen and...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit05 It showed that there was clearly more to inheritance than simply the coded sequence of DNA. We then realized that we were dealing with what is now known as genomic imprinting....

探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit03 Named after Henry Angelman, the pediatrician who first described Angelman syndrome. He referred to them as happy puppet children because it described, to some extent, the feat...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit02 Marcus Pembrey is one of a select band of scientists, a band of scientists who are daring to challenge an orthodoxy. They believe the lives of our parents, grandparents, and e...
探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit01 We are on the brink of uncovering a hidden world, a world that connects past and future generations in ways we never imagined possible. What this means is an environmental exp...
