  One of the most striking features found in the cosmic microwave background
data is the presence of an anomalous Cold Spot (CS) in the temperature maps
made by the Wilkinson Microwave Anisotropy Probe (WMAP). This CS has been
interpreted as the result of the presence of a collapsing texture, perhaps
coming from some early universe Grand Unified Theory (GUT) phase transition. In
this work we propose an alternative explanation based on a completely different
kind of texture which appears in a natural way in a broad class of brane-world
models. This type of textures known as brane-skyrmions can be understood as
holes in the brane which make possible to pass through them along the
extra-dimensional space. The typical scales needed for the proposed
brane-skyrmions to correctly describe the observed CS can be as low as the
electroweak scale.
