The black soils or 'tera preta' of the Amazon forests were created by burning and composting, in an Pre-Columbian farming style that is still much admired. A study has looked at how these ancient farming techniques may be used to help reduce deforestation.

Yuka, a young mammoth (Mammuthus primigenius), was found preserved in the permafrost of Siberia. Was this mammoth killed by lions or humans and why did the mammoth become extinct? Over 10,000 years later, scientists search for answers.

Modelling and hydrodynamics. If locomotion drove evolution in the same way as it seemed to drive the industrial revolution, ignoring the efficiency of an animal's metabolism, these models of marine animals could almost be the real thing.

Proof that the people of Madagascar are of Indonesian origin. Genetics have provided evidence of the Polynesian DNA (mitochondrial) in Madagascar from remote Oceania and Y chromosome 'haplogroups' from south-east Asia and Oceania.

In the history of science, sperm chemoattraction has long been recorded in a large variety of species, including plants. When a sperm can find an unfertilised egg more easily, sexual selection and a host of other efficient systems improve.

In extreme conditions or even in normal situations, an animal has to get itself back into the groove quickly after any disorientation. Survival normally depends on it. Your sense of place is dependent on either panorama-matching processes or by matching the actual 3D geometry of a place.

Some carnivores often lose their taste for sweet foods and mammals that swallow their food whole have little ability to taste, scientists have found.

When we wrote on Oetzi the archer who became 'The Iceman,' we must have missed the point. Now geneticists have jumped into the glacier with him and extracted his DNA for a whole-genome sequence.
