Scientists have invented an efficient way to produce apparently safe alternatives to human embryonic stem cells without destroying embryos, a long-sought step toward bypassing the moral morass surrounding one of the most promising fields in medicine.
A team of researchers at the Harvard Stem Cell Institute in Boston published a series of experiments Thursday showing that synthetic biological signals can quickly reprogram ordinary skin cells into entities that appear virtually identical to embryonic stem cells. Moreover, the same strategy can then turn those cells into ones that could be used for transplants.




From the attempted delivery of humanitarian aid to the Gaza Strip to the call for Israel to join the nuclear non-proliferation treaty, the number of things officials have warned against on the grounds of “hindering peace talks” has been staggering. This did not appear to expend to Israeli Foreign Minister Avigdor Lieberman’s office, however, as he delivered a speech at the United Nations calling for the mass expulsion of Arabs from Israel.
The search for a faraway planet that could support life has found the most promising candidate to date, in the form of a distant world some 120,000 billion miles away from Earth.
When Army investigators tried to interrogate Staff Sgt. Calvin R. Gibbs in May about the suspected murders of three Afghan civilians, he declined to answer questions. But as he was being fingerprinted, Gibbs lifted up his pant leg to reveal a tattoo.
About 80% of the world's population lives in areas where the fresh water supply is not secure, according to a new global analysis.
