A recent study has revealed that Marmoset monkeys have conversational patterns and etiquettes are remarkably similar to our own. It has long been known that primates use verbal communication in disputes or mating calls, but this is the first time we have seen any primate taking turns to 'speak' and glean so much information from verbal communication. They engage in chit chat for up to 30 minutes, just like we do.

It has long been thought that several different early human species existed 2 million years ago. But research published this week suggests that may need re-thinking, and that many of the species we thought were separate were actually all part of the same one.

Women in Laos are among the first in the developing world to receive a new vaccine against the virus that causes cervical cancer. The vaccine prevents the sexually transmitted human papillomavirus which causes 70% of cervical cancer cases. Laos is one of nearly a dozen countries to benefit from a programme to ensure that poorer countries also receive the latest vaccines.
