...Sewalls as they turn over in their graves. It will not be an act of inhospitality, mind you (even in death they are too well-bred for that), simply one of incredulity that in the land of the Bean and the Cod, he who is called Summus Pontifex, Vicarius Petri, Servus Servorum Dei, Dominus Deus, Nostra Papa, and addressed as Sanctissime Pater should be here. Their amazement is only matched...
...humanly happier, if ethically problematic, event occurred in England. The first baby ever conceived outside the human body was born 8% months after doctors there united sperm and egg in a laboratory petri dish and then implanted the embryo in the mother's womb...
...stop treating their new baby daughter as a medical oddity. Like every child ever conceived and born, the so-called test-tube baby [July 31] spent about nine months in utero and entered the world in a manner acceptable to society and medicine. Louise Brown was conceived in a Petri dish, not a test tube, and she developed and was born from within her natural mother's womb. To herald this girl as a test-tube baby only perpetuates the myth that we are entering a Huxleian world of callous indifference to childbirth and motherhood...
...cancer, they can grow tumor cells from people with common forms of cancer. (The mouse cells apparently produce some yet unidentified factor that supports the growth of certain human cancer cells.) According to Salmon, the cancer cells that thrive and form colonies in the laboratory's plastic petri dishes appear to be the tumor's "clonogenic," or "stem," cells. Though they account for less than 1% of all the cells in a tumor, these cells are thought to be the cancer's key replicating units; they divide and migrate, "seeding" new cancers in the body...
...Arizona team began applying anticancer drugs to cells taken from tumors and then culturing the cells in order to, in their words, "determine whether there are correlations between what is observed in the petri dish and in the patient." Tumor cells taken from nine people with myeloma, a bone marrow malignancy, and nine with ovarian cancer were exposed to varying concentrations of several anticancer drugs, then cultured in petri dishes. The researchers compared the effects of the drugs on the cultured cells with the patients' responses to the same drugs. In all but one case, the effects matched...
