Brain’s Map of Space Falls Flat When It Comes to Altitude

Animal’s brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain’s ‘map’ of space is surprisingly flat, according to new research.

In a study published online in Nature Neuroscience, scientists studied cells in or near a part of the brain called the hippocampus, which forms the brain’s map of space, to see whether they were activated when rats climbed upwards. (more…)

A new analysis of data from NASA’s Galileo spacecraft has revealed that beneath the surface of Jupiter’s volcanic moon Io is an “ocean” of molten or partially molten magma.

The finding, from a study published May 13 in the journal Science, is the first direct confirmation of such a magma layer on Io and explains why the moon is the most volcanic object known in the solar system. The research was conducted by scientists from UCLA, UC Santa Cruz and the University of Michigan–Ann Arbor. (more…)
