Genetic knowledge has played a direct role in pregnancy for more than 50 years, since the first use of amniocentesis to extract amniotic fluid containing fetal cells and DNA for analysis. Noninvasive ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

Researchers tested five species of commonly hunted waterfowl in the northeast Atlantic Flyway and, in every sample, found contaminants that could impact the health of the birds, as well as the ...

Another more interesting question would be whether this is convenient: to produce human beings from asexual reproduction, a bit like in Huxley's dystopia. Again, the answer would be no ...
