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…)
Darwin’s notion that only the fittest survive has been called into question by new research published in Nature.
A collaboration between the Universities of Exeter and Bath in the UK, with a group from San Diego State University in the US, challenges our current understanding of evolution by showing that biodiversity may evolve where previously thought impossible.
The work represents a new approach to studying evolution that may eventually lead to a better understanding of the diversity of bacteria that cause human diseases. (more…)
