It should never have been conceived.Scientists are sceptical about even the preliminary results Dr Shettles has claimed and they nearly all agree that the birth of a cloned human being is still far from being a practical possibility.
At the time that Clarke wrote his Wireless World article, the V-2s had already fallen on London, so it was well known that high-altitude rockets were a practical possibility.
However, cap-and-trade policies have spread round the world, to California, South Korea and parts of China for carbon-dioxide emissions as they had done for other pollutants, suggesting their implementation is a practical possibility.A market for these permits would ensure that a single carbon price emerges from mutually beneficial trades.
In contrast, Al-Kateb argued that the provisions only allowed unlawful non-citizens to be detained while removal was a practical possibility, and that if removal was not a practical possibility, then they should be released from detention, at least while it remained impractical.
This outbreak was the first influenza pandemic during which provision of real-time diagnostic virologic testing on large numbers of specimens had been a practical possibility.
Extracting the quantitative data is not time consuming so generating each patient's elastography data during their scan appointment time and using the information to influence management (e.g., whether to perform a biopsy or not) is a practical possibility.
We suggest that artificial disturbance of endogenous cytokinin levels at specific stages of organ development through targeted manipulation of particular family members is a practical possibility, and have identified several key candidate genes for genetic improvement of grain yield in this species.
Thanks to all this work, along with a great deal more funding than any academic robotics programme would ever garner, self-driving cars are now a practical possibility.They are not yet a business (a Google car would still cost far too much to put into production, even if the regulatory framework were to allow its widespread use), and it is not clear how they will turn into one.
Personalized medicine using stem cells is now a practical possibility because of the convergence of two distinct fields: genomic research, which has developed techniques to analyze cells on a genome-wide scale using a very small sample size (even single cells), and direct reprogramming, which has allowed researchers to obtain cells of virtually any phenotype from any human genotype.
Until now, being permeable to protons was not considered a practical possibility, but an international team of scientists led by Sir Andre, who shares the 2010 Nobel Prize for his work on graphene, has shown that the one-atom thick crystal acts like a chemical filter.
