How Octopus Arms Make Decisions

Researchers studying the behavior and neuroscience of octopuses have long suspected that the animals' arms may have minds of their own. A new model is the first attempt at a comprehensive ... read more

Bees Can Link Symbols to Numbers, Study Finds

We know bees get the concept of zero and can do basic math. Now researchers have discovered they may also be capable of connecting symbols to numbers. It's a finding that sheds new light on how ... read more

Researchers Discover the Source of New Neurons in Brain's Hippocampus

Researchers have shown, in mice, that one type of stem cell that makes adult neurons is the source of this lifetime stock of new cells in the hippocampus. These findings may help neuroscientists ... read more

Fish Appear to Recognize Themselves in the Mirror

The cleaner wrasse fish (Labroides dimidiatus), responds to its reflection and attempts to remove marks on its body during the mirror test -- a method considered the gold standard for determining ... read more
