Cataglyphis , the desert ant, is a genus in the subamily Formicinae. The most famous species is C. bicolor , the Sahara Desert ant. There, the midday sun is so hot that even the permanent residents, sand lizards, insects and a few birds, have to take shelter. But this is when, for not much than […]
The definition of life is not a simple one. According to classical textbooks, “living things are born, grow, reproduce and die”. But one doesn’t have to look too far to find some caveats in this interpretation. For example, when bacteria divide, can we really say that one is “giving birth” to the other? The part […]

Rabies is a fatal viral disease largely transmitted to humans by infected animals—predominantly from domestic dogs. The contagion is usually through the saliva from rabid animals. The disease is entirely preventable through prompt administration of post-exposure prophylaxis to bite victims and can be controlled through widely applied vaccination of domestic dogs. Yet, rabies is still […]

I am not sure whether we should be proud of this legacy. The «little fly» is one of humanity most dangerous and terrible enemies. Many species of mosquitoes act as vectors of […]
The nose is one of the strangest structures of human anatomy. It is much more different from our closest relatives than other parts of the body, it is sexually dimorphic, being on average larger in males than in females, and it is different among different hominin species and among different ethnic groups. Size and shape […]
Cooperation is the process of groups of individuals working or acting together for common or mutual benefit. Members of social insect societies cooperate in sophisticated modes. The specialization of individual ants in performing particular tasks or roles tend to increase group efficiency that is best exemplified by workers that display a wide array of specific […]

Neanderthals ( Homo neanderthalensis ) were a species –some say a subspecies although most authors consider there is enough evidence to consider them as a separate species– of human closely related to us. They were firstly discovered in a cave in the Neander Valley («Tal» in German), about 12 km east of Düsseldorf. There is […]
