Spiritual effects of hallucinogens persistIn a follow-up to research showing that psilocybin, a substance contained in "sacred mushrooms," produces substantial spiritual effects, a Johns Hopkins team reports that those beneficial effects appear to last more than a year.
Writing in the Journal of Psychopharmacology, the Johns Hopkins scientists note that most of the 36 volunteer subjects given psilocybin, under controlled conditions in a Hopkins study published in 2006, continued to........Go to the Psychology news blog (Added on 7/1/2008 9:38:49 PM)
Find ways to predict IVF successScientists at the Stanford University School of Medicine have identified a method that can predict with 70 percent accuracy whether a woman undergoing in vitro fertilization therapy will become pregnant. This information may someday help the tens of thousands of couples who want to undergo IVF each year, and their doctors, decide on their course of action.
