A blind, cave-dwelling amphibian appears to live for more than 100 years, an inexplicable feat that may eventually (when explained) provide insights into aging in other species.
But first, scientists have to unravel the mystery of how the species — known as “human fish” — achieves such longevity. “We cannot, at this time, say how this animal manages to survive such a long time,” said eco-physiologist Yann Voituron, from the Université Claude Bernard – Lyon, first author of the study published online today (July 21) in Biology Letters.

The Galilean satellites, or Jupiter’s moons as they are known to lay-folk like myself, were the first objects found orbiting something other than Earth or the Sun.

Though they may be large for moons, Jupiter dwarfs them, weighing in at five thousand times more massive and causing them extreme tidal stress. Jupiter is also radioactive, bathing its moons in high-energy electron beams and radio emissions.
