The ability for the human mind to gauge hierarchical structures in music over the span of lengthy works suggests that we exercise greater cognition in that skill than in language.
Induced pluripotent stem cells allow researchers to ethically create any cell type from an adult cell, raising hopes for regenerative medicine. Eyebrows started to raise recently, though, when labs grew brains with them and turned others into sperm and egg cells.
Epigenetics has become a hot topic in biology. There are players "above DNA"– some heritable – that may be more important than the genetic code itself.
Another epic photo of Earth from space was taken on July 19 of Earth from Saturn by Cassini, and released on July 22. From Mercury, the MESSENGER spacecraft also portrayed Earth as a small dot.
