OUR ability to use and manipulate numbers is integral to everyday life - we use them to label, rank, count and measure almost everything we encounter. It was long thought that numerical competence is dependent on language and, therefore, that numerosity is restricted to our species. Although the symbolic representation of numbers, using numerals and words, is indeed unique to humans, we now know that animals are also capable of manipulating numerical information. One study published in 1998, for example, showed that rhesus monkeys can form spontaneous representations of small numbers and…

Earlier studies have found that different parts of a rodent's brain are activated in the face of danger, depending on how imminent that danger is. Now, scientists at University College London has found the…
