What we eat can say a lot about us - where we live, how we live and eventually even when we lived. From the analysis of the intestinal contents of the 5,200-year-old Iceman from the Eastern Alps, Professor James Dickson from the University of Glasgow in the UK and his team have shed some light on the mummy's lifestyle and some of the events leading up to his death.
By identifying six different mosses in his alimentary tract, they suggest that the Iceman may have travelled, injured himself and dressed his wounds. Their findings1 are published in the December issue of Springer's journal Vegetation History and Archaeobotany, which is specially dedicated to Oetzi the Iceman.
The Iceman is the first glacier mummy to have fragments of mosses in his intestine. This is surprising as mosses are neither palatable nor nutritious and there are few reports of mosses used for internal medical treatments. Rather, mosses recovered from archaeological sites tend to have been used for stuffing, wiping and wrapping.
Dickson and colleagues studied the moss remains from the intestines of the Iceman on microscope slides, to find out more about his lifestyle and events during the last few days of his life. Their paper describes in detail the six different mosses identified and seeks to provide answers to two key questions in each case. Firstly, where did the Iceman come in contact with each species; secondly, how did each come to enter his alimentary tract.
In particular, the authors suggest that one type of moss is likely to have been used to wrap food, another is likely to have been swallowed when the Iceman drank water during the last few days of his life, and yet another would have been used as a wound dressing. One type of moss in the Iceman's gut is not known in the region where the mummy was found, implying that the Iceman must have travelled.
Other papers in this special issue of Vegetation History and Archaeobotany look at subfossil caprine dung from the discovery site of the Iceman, plant economy and village life in Neolithic lake dwellings at the time of the Alpine Iceman, and the significance of the Tyrolean Iceman for the archaeobotany of Central Europe.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
