Analysis of Iron Age textiles indicates that during c. 1000-400 BC Italy shared the textile culture of Central Europe, while Greece was largely influenced by the traditions of ancient Near East.
Scientists confirm that the age and content of an old sack is in accordance with a medieval myth about Saint Francis of Assisi.
How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? A study led by the Spanish National Research Council researcher, Antonio Rosas, has studied the fossil remains of a Neanderthal child's skeleton in order to establish whether there are differences between the growth of Neanderthals and that of sapiens.
David Lohman, associate professor of biology at The City College of New York's Division of Science, is co-author of a landmark paper on butterflies 'An illustrated checklist of the genus Elymnias Hübner, 1818 (Nymphalidae, Satyrinae).' Lohman and his colleagues from Taiwan and Indonesia revise the taxonomy of Asian palmflies in the genus Elymnias in light of a forthcoming study on the butterflies' evolutionary history.
The paper outlines how the urban design of the city of Teotihuacan differed from past and subsequent cities, only to be rediscovered and partially modelled on many centuries later by the Aztecs.
Scientists say that a large, now extinct, frog called Beelzebufo that lived about 68 million years ago in Madagascar would have been capable of eating small dinosaurs. The conclusion comes from a study of the bite force of South American horned frogs from the living genus Ceratophrys, known as Pacman frogs for their characteristic round shape and large mouth, similar to the video game character Pac-Man.
The nearly nine hundred giant stone statues discovered by the first Europeans to land on Easter Island seemed at odds with the small population found living there. It is believed a once thriving community witnessed sweeping ecological change and suffered internal conflict, resulting in a population crash. A new detailed study of the farming potential of the Island suggests it could have sustained 17,500 people at its peak.
Very simple ribonucleic acid (RNA) molecules (compounds similar to Deoxyribonucleic acid (DNA)) can join other RNA molecules to themselves though a chemical reaction called ligation. The random joining together of different pieces or RNA could give rise to a group of molecules able to produce copies of themselves and so kick start the process of life. Wits researchers discovered exactly how this was done.
The first large-scale genetic study of people in Papua New Guinea has shown that different groups within the country are genetically highly different from each other. Scientists at the Wellcome Trust Sanger Institute and their colleagues reveal that the people there have remained genetically independent from Europe and Asia for most of the last 50,000 years, and that people from the country's isolated highlands region have been completely independent even until the present day.
The Ancient Greeks may have built sacred sites deliberately on land affected by previous earthquake activity, according to a new study by BBC presenter Iain Stewart MBE, Professor of Geoscience Communication at the University of Plymouth.
