A man wakes up one morning to...

A man wakes up one morning to find a bear on his roof. So he looks in the yellow pages and sure enough, there's an ad for "Bear Removers."
He calls the number, and the bear remover says he'll be over in 30 minutes. The bear remover arrives, and gets out of his van. He's got a ladder, a baseball bat, a shotgun and a mean old pit bull.
"What are you going to do," the homeowner asks?
"I'm going to put this ladder up against the roof, then I'm going to go up there and knock the bear off the roof with this baseball bat. When the bear falls off, the pit bull is trained to grab his testicles and not let go. The bear will then be subdued enough for me to put him in the cage in the back of the van."
He hands the shotgun to the homeowner.
"What's the shotgun for?" asks the homeowner.
"If the bear knocks me off the roof, shoot the dog."

Cloned mice

In 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.
