A man walks into a store to buy a Barbie doll for his daughter. “How much is that Barbie in the window?”, he asks the shop assistant.
In a manner she responds, “Which Barbie? We have Barbie Goes to the Gym for $19.95, Barbie Goes to the Ball for $19.95, Barbie Goes Shopping for $19.95, Barbie Goes to the Beach for $19.95, Barbie Goes Nightclubbing for $19.95, and Divorced Barbie for $395.00.”
The guy asks, “Why is Divorced Barbie different from all the others?”
“That’s obvious,” the assistant states, “Divorced Barbie comes with Ken’s house, Ken’s car, Ken’s boat, Ken’s furniture…”

CAMBRIDGE, Mass. (UPI) -- U.S. scientists say they've found a common class of freshwater invertebrates called bdelloid rotifers is extraordinarily resistant to ionizing radiation.
Harvard University researchers said the animals survive and continue to reproduce after being exposed to doses of gamma radiation much greater than can be tolerated by any other animal species studied.
Because free radicals such as those generated by radiation have been implicated in inflammation, cancer and aging in higher organisms, Harvard Professor Matthew Meselson and graduate student Eugene Gladyshev said their findings could stimulate new lines of research into these medically important problems.
The researchers found bdelloid rotifers Adineta vaga and Philodina roseola -- about a half-millimeter in size and commonly observed under microscopes -- remained reproductively viable after doses of radiation roughly five times greater than other classes of rotifers and other animals could endure.
The research, supported by the National Science Foundation's Eukaryotic Genetics Program, is reported in the Proceedings of the National Academy of Sciences.
DALLAS (UPI) -- U.S. and British scientists said they might have discovered why some species can nearly never interbreed -- a key insight into the basis of reproduction.
University of Texas Southwestern Medical Center researchers said their finding might point to a possible malaria vaccine, thwarting the disease that kills about 1 million people each year, primarily children in sub-Saharan Africa.
The researchers found sexual reproduction begins with two genetically different steps: First, two reproductive cells must latch onto each other with one protein, and secondly they must fuse their membranes to form a single cell using a different protein.
The scientists collaborated with malaria experts at Imperial College London and found the parasite causing malaria also uses that two-step process. When they blocked "male" and "female" malarial cells from fusing, spread of the mosquito-borne disease was stopped.
The research is to appear in the April 14 issue of the journal Genes and Development and is now available at the journal's Web site.
