Instead of reacting to the perception that higher education has let us down by forcing colleges into justifying their value through statistics, the Department of Education ought to address root problems of higher education—many of which stem all the way back to early childhood learning—in order to ensure the United States’s continued academic success. In fact, other parts of the department’s report chart out commendable efforts in the pursuit of educational accessibility and availability. It’s unfortunate that these come nestled in amongst the commission?...
...involves turning back the clock on adult cells, worked better with younger, more "embryo"-like cells. The less that the cloning process has to undo, the theory goes, the more successful the technique will be. In fact, there was good evidence to support this theory: In previous studies embryonic stem cells, which can generate all of the body's cell types, produced clones ten times more efficiently than adult stem cells, which can develop into only a restricted number of cell types. And when scientists had tried to clone fully differentiated cells, they had very little luck...
...Connecticut group's report, however, found that fully differentiated cells could prove useful in cloning, although they're still not sure why. Nearly 40% of these more mature cells developed to the blastocyst stage, at which point stem cells can be extracted, while only 4% of the more actively dividing cells did so. "That is good news for therapeutic cloning," notes Yang. From his research, Yang believes that most of the problems that occur in cloning occur after the blastocyst stage, when the embryo begins to divide to re-create all the tissue types in a developing fetus. "Based...
What causes changes in both the dark matter and the genes themselves as one species evolves into another is random mutation, in which individual base pairs--the "letters" of the genetic alphabet--are flipped around like a typographical error. These changes stem from errors that occur during sexual reproduction, as DNA is copied and recombined. Sometimes long strings of letters are duplicated, creating multiple copies in the offspring. Sometimes they're deleted altogether or even picked up, turned around and reinserted backward. A group led by geneticist Stephen Scherer of the Hospital for Sick Children in Toronto has identified...
...reason for Utah's MLM success seems again to stem from the church. Nature's Sunshine became the first to go that route back in 1975, and Mormons--trained in door-to-door evangelism through compulsory missions--proved natural salespeople. "The church provides a network--a real plus factor for MLM companies," says Rory Mahony, general manager of Nature's Way, which sells through health-food and vitamin shops. Under direct-sales plans, independent reps earn commissions for items they sell but also receive payouts by recruiting others to become distributors. The bigger one's network, the better...
