Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. In fact some dogs are distinctly more pessimistic than others, new research shows.
Dogs look at a person interacting with a new object longer than a person interacting with a familiar object moved to a different location, suggesting perception of goal-directed behavior, according to a new study.
A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs.
