This picture taken on January 20, 2009 shows a newly born Madagascan lemur, Propithecus coronatus, an en-dangered species named Tahina, at Besancon Zoo, eastern France.
I travel around the world and have worked on 6 of the 7 continents studying lowland gorillas in central Africa, grizzly bears in North America, ringtail lemurs in Madagascar, cougars in California, lions in Tanzania, and more.
What is particularly intriguing for Dr Krasnow and his colleagues, though, is that, in captivity at least, mouse lemurs suffer several illnesses which affect humans too.
