...think that would be a huge deal. The scientists, from three private labs in La Jolla, Calif., and Detroit made the clones by a technique called somatic cell nuclear transfer: They took the nuclei from skin cells of adult men, inserted the genetic material into enucleated eggs from female donors, and got the eggs to begin dividing, forming embryos containing stem cells. In principle, replacement tissues grown from those cells would be genetically identical to the men they came from. So they could, in principle, be used to fix failing organs, without any fear of rejection...
...last major stops for love signals in the brain are the caudate nuclei, a pair of structures on either side of the head, each about the size of a shrimp. It's here that patterns and mundane habits, such as knowing how to type and drive a car, are stored. Motor skills like those can be hard to lose, thanks to the caudate nuclei's indelible memory. Apply the same permanence to love, and it's no wonder that early passion can gel so quickly into enduring commitment. The idea that even one primal part of the brain is involved...
Researchers inserted a gene for a red fluorescent protein into the nuclei of a cat's skin cells, which were transplanted into eggs that gave rise to the modified clones...
...generating stem cells is suddenly possible for anyone with a basic background in molecular biology. No special expertise in handling chromosomes, nuclei or eggs is needed...
Despite the concerns, Spanish government delegate to Ceuta Jenaro Garcia-Arreciado insists the city is safe. "Certainly we're closer to terrorist nuclei, but the threat isn't any greater here than on the mainland. And given all the security forces in Ceuta, we are, paradoxically, one of the safest cities in Spain." He points out that with the help of Morocco, which appoints Ceuta's imams, the city keeps radical messages out of Príncipe's mosques. But Yalila Liazid, director of the Sidi Embarek Koranic school and daughter of Ceuta's most important imam...
