this progress is a sensation for the scientific community d.n.a. scissors have prompted the kind of excitement that surgery once did in the 19th century. to think it has to. turn on the surgery as it often could assume a similar important. i m going to predict that 50 years from now we ll probably see as many people undergoing genome surgery as the conventional kind. professor who called his team aims to find a cure for hemophilia using cells donated by a boy who has the hereditary bleeding disorder the scientists are well acquainted with a mutation in question it s caused by a piece of d.n.a. being the wrong way around and as a result impossible for cells to read this prevents them from forming a particular clotting factor that s needed for a womb to heal. the. really kind of life now this is this.
she looked around she noticed something. blood not just where elizabeth lay, but high up along the staircase walls, too. too much blood, she thought, for a slip and fall. if you fell down the stairs, why would there be blood splurted up the side of the walls? it didn t make any sense to me. reporter: and she says there were household details out of order: like the table that liz set out every night with the girls breakfast plates. it was bare. the snow boots she routinely left by the front door, still on her feet. liz never wore her boots in the house. she d always took her boots off. and that was another clue to me that something was wrong. it s obvious that she was either running from someone or trying to escape. reporter: amybeth thought a full-fledged investigation would ensue. but, as she tells it, michael peterson spoke to the authorities that day, relating that elizabeth had a hereditary bleeding disorder. perhaps she d had a stroke and fallen down the stairs.
