12、ientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had 5 died. They used strong chemicals to remove the donors cells, leaving a tissue scaffold. This was repopulated(重新构成) with cells from Ms Castillos windpipe and nose, and stem cells from her bone

13、marrow. After four 6 the cells had grown sufficiently for the trachea to be transplanted into Ms Castillo. Currently, transplant patients have to take drugs for 7 of their lives to prevent their bodies rejecting the new 8 . These 9 can have bad side-effects, and do not always prevent rejection. But

14、by using Ms Castillos own cells, 10 were able to trick her body into 11 the new trachea was her own organ. Five months on, Claudia Castillo is in 12 health.

19、on earth, also exist in space. One of the primary sources of this knowledge lies in numerous tests run on meteorites(陨星) that have landed on earth. Small traces of amino acids have been found, again and again, from a countless number of meteorites. An American scientist and researcher, Sandra Pizzar

20、ello, has recently discovered that the amino acids found on earth share the same simple structure as amino acids found in outer space. This discovery offers proof that extraterrestrial(来自地球外的) life could, quite realistically, resemble life on earth. Many years ago, Pizzarello and a colleague conduct

21、ed research on amino acids extracted(提取) from a meteorite that landed in Australia in 1969. As they analyzed the material, they discovered a greater number of acids indicating a tendency towards “left-handedness” over “right-handedness”.Further evidence to support these findings came from the analys

22、is of pristine meteorites found in Antarctica. The frozen conditions of Antarctica ensure that meteorites are preserved and remain unaffected by the earth. These buried meteorites are usually discovered due to constant motion of the ice, which eventually brings the objects back to the surface.Accord

23、ing to Pizzarello, this discovery is important because it shows that a key molecular (分子的)trait(特征) that defines life here on earth appears to have had the same effect on the cosmic lineage(世系) of life in outer space.
