Claude Monet, for example, was known to…

Chimp beats humans at photographic memory task

Researchers from Kyoto University’s Primate Research Institute report that a young chimp can out-perform university students on a working memory task. (Cognitive psychologists use the term working memory to refer to the temporary storage and manipulation of information.) The researchers developed a memory test called the limited-hold memory task in order to compare the working…

Do insects feel pain?

Using sophisticated techniques to silence or activate specific neurons, researchers from Stanford University have established that a simple behaviour used by fruit fly larvae to evade attack from parasitic wasps is triggered by a type of sensory neuron that is similar to the neurons which respond to painful stimuli in mammals.
