In a paper publishing August
7th in the Open Access journal PLOS Biology, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI - CBG) succeeded in mimicking the sustained expression of the transcription factor Pax6 as seen in the developing human brain, in mouse cortical progenitor cells.
As an example of how active the debate over his theory is
in the scientific literature, Sloan & Wolfendale, 2013 (
Open access), which criticises the theory, was published
in the
journal Environmental Research Letters on
7th November 2013, but coincidentally, on the next day, a new paper by Svensmark — Svensmark et al., 2013 (Abstract;
access to ArXiV preprint)-- was published
in Physics Letters A.
