The blind Mexican cavefish (Astyanax mexicanus) have not only lost their sight but have adapted to perpetual darkness by also losing their pigment (albinism) and having altered sleep patterns.

The largest galaxies within the largest halos of dark matter also harbor the most massive black holes, which has led to speculation that exotic physics controls the growth of black holes and their link to massive dark matter halos.

A new theory pioneered by cosmologist Christos Tsagas claims that some of the most confounding observations and theories in modern physics, specifically that of an expanding universe caused by slippery dark energy, may be just an illusion created by the location of our corner of the cosmos relative to other parts. The explanation hinges on an observation known as 'dark flow' which states that our section of the universe, roughly 2.5 billion light years wide, is moving at a different speed and direction than other sections.
