Light has been frozen in the ultracooled Bose-Einstein condensates. In these systems the atoms gather in a single quantum state and act in synchrony. Quantum space-time calibrations are metric. At 60 km/hr light's compressed energy isn't amplified in these condensates. A pulse of slow light transiting a condensate vortex would rotate with this gas like the phenomenon expected to occur near black holes.

A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research.  The new study refutes the 'island rule' which says that in island environments small mammals such as rodents tend to evolve to be larger, and large mammals such as elephants tend to evolve to be smaller, with the original size of the species being the key determining factor in these changes.
