...Stem-Cell Study Moves Ahead...
Perhaps if Alice Park had interviewed even one opponent of embryonic research, her article would not have lacked so many important facts. Adult (nonembryonic) stem cells, dismissed by Park as "less versatile," have already treated thousands of actual human patients in the fight against conditions like juvenile diabetes--a disease mentioned anecdotally by Park. Different types of adult stem cells (there are several) can be used for different situations; we do not need a one-size-fits-all cell that can become anything. Brian Gillin, BROOMALL...
...including former President George W. Bush, is against stem-cell research. It's embryonic-stem-cell research that's debatable. The so-called dark days of the Bush Administration's stem-cell restrictions were a result of our former President's courage to enact policies that reflected his belief (shared by many) that life begins at conception. It's because of these restrictions that scientists discovered the exciting potential of other types of stem cells. Diann Claassen, TEMPERANCE, MICH...
...also encoded in DNA, and until the 1980s, biologists had almost no knowledge of the genes that built them. Over the past 25 years, biologists have identified many of the genes that help build embryos. A number of them help lay out the embryo's blueprint by letting cells know where they are. The cells absorb proteins floating around them, and the signals trigger the cells to make other proteins, which in turn clamp onto certain bits of DNA to switch neighboring genes on and off. This network of genes eventually leads a cell to give rise...
...gate.Leaving the gate, I joined forces with Josh and Amy—a staffer for Rep. Robert Wexler (D-FL) and his behavioral science funding lobbyist wife—in search of an alternate route. On our first attempt we overheard a displeased Samuel L. Jackson working his cell phone over his own inability to make it through the barricade. At least we weren’t the only ones. Eventually, after a three-mile detour, around the White House and parade route, we made the six blocks along Constitution Avenue and reached the purple ticket entry gate. The time...
