Last week, opponents of human embryonic stem cell research declared that new research techniques have cleared away the ethical controversies that have plagued stem cell science. From Vatican City to the Bush administration, spokesmen gave sound bites of “we told you so”; with above-the-fold headlines in every major paper describing how scientists can now create stem cells without destroying embryos, opponents of embryonic stem cell research claimed to hold unbeatable evidence on their side...
Pardon us for raining on this parade of jubilation. A “milestone” the research of groups in Japan and Wisconsin may be, but their method does not yet negate the need for controversial research on embryonic stem cells. Scientists and supporters of stem cell research should not allow conservatives to declare victory and should persevere in their fight to eliminate restrictions on embryonic stem cell research...
...Stem cells generated by this method are ideal not just because they are free of political and moral baggage. They can also be coaxed into becoming any type of tissue, and then be transplanted back into the donor with little risk of rejection. Still, these cells are far from ready for medical use. The viruses used to ferry the genes that manipulate the cells can introduce genetic mutations and cancer. And with myriad ways to reprogram a cell, sorting out the best ones will take time - meaning that stem cells from embryos will remain useful (and controversial) for a while...
...iPhone, but I plan to in the near future. Like Grossman, I'm sick of the sour grapes from naysayers who moan about what the iPhone doesn't do and ignore what it does do and just how well it does it. I hate my conventional cell phone with its 100-page, four-language manual that I can't begin to understand. I've used the iPhone without having to look at the manual. And the only language required is intuition. Brad Cathey, Wheaton, Illinois...
...this straight: TIME passed up inventions that save energy, produce energy, make us safer, make our commutes easier, protect us from diseases, reduce our impact on our finite resources and bring knowledge to the Third World to name a cool new cell phone as Invention of the Year?
