Evidence from ancient European graves raises questions about ritual human sacrifice
05-29-2007 · EurekAlert!A fascinating new paper explores ancient multiple graves and raises the possibility that hunter gatherers in what is now Europe may have practiced ritual human sacrifice. This practice -- well-known in large, stratified societies -- supports emerging research that argues that the level of social complexity reached in the distant past by groups of hunter gatherers was well beyond that of many more recent small bands of modern foragers.

06-16-2007 · EurekAlert!
The long-running controversy about the origins of the Etruscan people appears to be very close to being settled once and for all, a geneticist will tell the annual conference of the European Society of Human Genetics on Sunday, June 17. Professor Alberto Piazza, from the University of Turin, Italy, will say that there is overwhelming evidence that the Etruscans, whose brilliant civilization flourished 3000 years ago in what is now Tuscany, were settlers from old Anatolia, now in southern Turkey.

- Where broken DNA is repaired
08-02-2007 · EurekAlert!
Intricate DNA repair mechanisms in cell nuclei are constantly working to fix damaged DNA, but for mammalian cells, exactly where the repair work happens has been an unanswered question. By comparing computer models of damaged human DNA with microscopic images of radiation-induced damage in human cells, researchers at Lawrence Berkeley National Laboratory and their colleagues have found evidence for specific regions where broken DNA is concentrated for repair.

- ESF EUROCORES Program OMLL helps uncover ancient human behavior
06-20-2007 · EurekAlert!
A major question in evolutionary studies today is how early did humans begin to think and behave in ways we would see as fundamentally modern? One index of "behavioural modernity" is in the appearance of objects used purely as decoration or ornaments. Such items are widely regarded as having symbolic rather than practical value. By displaying them on the body as necklaces, pendants or bracelets or attached to clothing this also greatly increased their visual impact.

- Most ancient case of tuberculosis found in 500,000-year-old human; points to modern health issues
12-07-2007 · EurekAlert!
Although most scientists believe tuberculosis emerged only several thousand years ago, new research from the University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.The discovery of the new specimen of the human species, Homo erectus, suggests support for the theory that dark-skinned people who migrate northward from low, tropical latitudes produce less vitamin D, which can adversely affect the immune system as well as the skeleton.

- Time-lapse recordings reveal why IVF embryos are more likely to develop into twins
07-02-2007 · EurekAlert!
Evidence from time-lapse recordings of the formation of early embryos in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. The research presented at annual meeting of the European Society of Human Reproduction and Embryology, Monday, July 2, has shown that the culture in which the IVF embryos are formed is possibly responsible for the embryos dividing into twins.

- Nature Conservancy study raises major questions on biofuels
02-07-2008 · EurekAlert!
A new Nature Conservancy study finds that converting land for biofuel crops results in major carbon emissions, actually worsening the problem of global warming instead of mitigating it. "This research examines the conversion of land for biofuels and asks the question 'Is it worth it?' Does the carbon you lose by converting forests, grasslands, and peatlands outweigh the carbon you 'save' by using biofuels instead of fossil fuels? And surprisingly, the answer is no,? said lead author Joe Fargione, a scientist for The Nature Conservancy.

How are human beings reacting to displacement of their natural, or "given," world by a built world? This question lay at the heart of a talk given by Professor Rosalind Williams, the last in a series of fall colloquia titled "The Big Questions."
