Ancient remains put teeth into Barker hypothesis Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans. "Prehistoric remains are providing strong, physical evidence that people who acquired tooth enamel defects while in the womb or early childhood tended to die earlier, even if they survived to adulthood," says Emory anthropologist George Armelagos, who recently published the first summary of prehistoric evidence for the Barker hypothesis.

DNA testing on 2,000-year-old bones in Italy reveal East Asian ancestry Researchers excavating an ancient Roman cemetery were surprised when DNA testing on a set of bones revealed East Asian ancestry. Contact: Jane Christmas Public Release: 26-Jan-2010
Lost Roman law code discovered in London Part of an ancient Roman law code previously thought to have been lost forever has been discovered by researchers at UCL's department of history. Simon Corcoran and Benet Salway made the breakthrough after piecing together 17 fragments of previously incomprehensible parchment. The fragments were being studied at UCL as part of the Arts & Humanities Research Council-funded "Projet Volterra" -- a 10-year study of Roman law in its full social, legal and political context.

The sea level has been rising and falling over the last 2,500 years The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels. This has been shown in a new study supervised by Dr. Dorit Sivan, head of the department of maritime civilizations at the University of Haifa. "Rises and falls in sea level over relatively short periods do not testify to a long-term trend," Dr. Sivan explains. Contact: Rachel Feldman Public Release: 26-Jan-2010
Last Neanderthals died out 37,000 years ago The last Neanderthals in Europe died out at least 37,000 years ago -- and both climate change and interaction with modern humans could be involved in their demise, according to new research from the University of Bristol published today in PLoS ONE.

Study: Animals populated Madagascar by rafting there How did the lemurs, flying foxes and narrow-striped mongooses get to the large, isolated island of Madagascar sometime after 65 million years ago? A pair of scientists say their research confirms the longstanding idea that the animals hitched rides on natural rafts blown out to sea. Contact: Greg Kline Public Release: 12-Jan-2010
Stable climate and plant domestication linked Sustainable farming and the introduction of new crops relies on a relatively stable climate, not dramatic conditions attributable to climate change. Basing their argument on evolutionary, ecological, genetic and agronomic considerations, Dr. Shahal Abbo, from the Hebrew University of Jerusalem, Israel, and colleagues, demonstrate why climate change is not the likely cause of plant domestication in the Near East. Their thesis is published online in Springer's journal Vegetation History and Archaeobotany. Contact: Joan Robinson Public Release: 11-Jan-2010
Ancient Egyptian cosmetics: 'Magical' makeup may have been medicine for eye disease There's more to the eye makeup that gave Queen Nefertiti and other ancient Egyptians royals those stupendous gazes and legendary beauty than meets the eye. Scientists in France are reporting that the alluring eye makeup also may have been used to help prevent or treat eye disease by doubling as an infection-fighter. Their findings are scheduled for the Jan. 15 issue of ACS' Analytical Chemistry, a semi-monthly journal. Contact: Michael Bernstein Public Release: 11-Jan-2010
Use of body ornamentation shows Neanderthal mind capable of advanced thought The widespread view of Neanderthals as cognitively inferior to early modern humans is challenged by new research from the University of Bristol published today in Proceedings of the National Academy of Sciences.

Most ancient Hebrew biblical inscription deciphered Professor Gershon Galil of the department of biblical studies at the University of Haifa has deciphered an inscription dating from the 10th century BCE (the period of King David's reign), and has shown that this is a Hebrew inscription. The discovery makes this the earliest known Hebrew writing. The significance of this breakthrough relates to the fact that at least some of the biblical scriptures were composed hundreds of years before the dates presented today in research.

Fossil footprints give land vertebrates a much longer history The discovery of fossil footprints from early backboned land animals in Poland leads to the sensational conclusion that our ancestors left the water at least 18 million years earlier than previously thought. The results of the Polish-Swedish collaboration are published online this week in Nature. Contact: Per Ahlberg Public Release: 7-Jan-2010
30,000-year-old teeth shed new light on human evolution The teeth of a 30,000-year-old child are shedding new light on the evolution of modern humans, thanks to research from the University of Bristol published this week in PNAS. Contact: Hannah Johnson Public Release: 31-Dec-2009

Modern behavior of early humans found half-million years earlier than previously thought Evidence of sophisticated, human behavior has been discovered by Hebrew University of Jerusalem researchers as early as 750,000 years ago -- some half a million years earlier than has previously been estimated by archaeologists.

Exploring the Stone Age pantry The consumption of wild cereals among prehistoric hunters and gatherers appears to be far more ancient than previously thought, according to a University of Calgary archaeologist who has found the oldest example of extensive reliance on cereal and root staples in the diet of early Homo sapiens more than 100,000 years ago.

Science's breakthrough of the year: Uncovering 'Ardi' The research that brought to light the fossils of Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia, has topped Science's list of this year's most significant scientific breakthroughs. The journal also identifies nine other important scientific accomplishments from this past year in a top 10 list, appearing in a special news feature in the journal's Dec. 18, 2009, issue.

The impact of the diffusion of maize to the Southwestern United States An international group of anthropologists offers a new theory about the diffusion of maize to the Southwestern United States and the impact it had. Published in the Proceedings of the National Academy of Sciences, the study, co-authored by Gayle Fritz, Ph.D., professor of anthropology at Washington University in St. Louis, and colleagues, suggests that maize was passed from group to group of Southwestern hunter-gatherers.

'Hobbits' are a new human species -- according to the statistical analysis of fossils Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease. Using statistical analysis on skeletal remains of a well-preserved female specimen, researchers determined the "hobbit" to be a distinct species and not a genetically flawed version of modern humans. Details of the study appear in the December issue of Significance, the magazine of the Royal Statistical Society, published by Wiley-Blackwell. Contact: Dawn Peters Public Release: 17-Nov-2009
Heart disease found in Egyptian mummies Hardening of the arteries has been detected in Egyptian mummies, some as old as 3,500 years, suggesting that the factors causing heart attack and stroke are not only modern ones; they afflicted ancient people, too. Contact: Tom Vasich |
