The identification of molecular markers linked to loci affecting leaf morphology traits resolves conflicting hypotheses on the genetics of these complex traits and has potential for molecular breeding improvement of white clover.

FORBES: The Four-Leaf Clover Gene?

Last year Dr Benenson's team developed one of the most complex cell-based molecular circuits created so far, though it is still much simpler than systems built in test tubes.

The world at the molecular level is a three-dimensional one with its own busy, complex environment.

FORBES: Autism And Genetics: It's Complicated

As the brain grows older, it undergoes complex and poorly understood changes from the biochemical, to the molecular, structural and functional that lead it to shrink.
