A young woman, pursuing a graduate degree in art history, was going to Italy to study the country's greatest works of art.
Since there was no one to look after her grandmother while she was away, she took the old lady with her.
At the Sistine Chapel in the Vatican, she pointed to the painting on the ceiling. 'Grandma, it took Michelangelo a full four years to get that ceiling painted.'
'Oh my, 'the grandmother says.
'He and I must have the same landlord.'
Cloned miceIn 1998, in the 23 July issue of the science journal, Nature, an international team of scientists led by Ryuzo Yanagimachi of the University of Hawaii, announced they had accomplished the first reproducible cloning of a mammal from adult cells to produce three generations of cloned mice, more than 50 identical sisters in all. The cloning technique was said to be more reliable than the one used to create Dolly the sheep. Their “Honolulu technique”affords the researchers greater ability to manipulate the adult donor nucleus. This ability will have application industry-wide in increasing the study of the role genes play in aging and the disease processes.Image: Two-cell mouse embryo. |
