'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.

Ancient penguin DNA raises doubts about accuracy of genetic dating techniques Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent.

Remains of Minoan-style painting discovered during excavations of Canaanite palace The remains of a Minoan-style wall painting, recognizable by a blue background, the first of its kind to be found in Israel, was discovered in the course of the recent excavation season at Tel Kabri. This fresco joins others of Aegean style that have been uncovered during earlier seasons at the Canaanite palace in Kabri. "It was, without doubt, a conscious decision made by the city's rulers who wished to associate with Mediterranean culture." Contact: Rachel Feldman Public Release: 5-Nov-2009
Atlanta's Fernbank Museum tracks infamous conquistador through Southeast Atlanta's Fernbank Museum of Natural History has discovered evidence of Hernando de Soto's 1540 journey through the Southeast. No evidence of De Soto's path from Tallahassee to North Carolina has been found until now, and few sites have been located anywhere. Fernbank archaeologist Dennis Blanton has amassed an impressive collection of objects revealing a probable stop in today's Telfair County, Ga. He'll present his findings at the Southeastern Archaeological Conference on Nov. 5 in Mobile. Contact: Brandi Berry Public Release: 4-Nov-2009

New clues to the Falklands wolf mystery Ever since the Falklands wolf was described by Darwin himself, the origin of this now-extinct canid found only on the Falkland Islands far off the east coast of Argentina has remained a mystery. Now, researchers reporting in the Nov. 3 issue of Current Biology who have compared DNA from four of the world's dozen or so known Falklands wolf museum specimens to that of living canids offer new insight into the evolutionary ancestry of these enigmatic carnivores.

Tsunami waves reasonably likely to strike Israel "There is a likely chance of tsunami waves reaching the shores of Israel," says Dr. Beverly Goodman of the Leon H. Charney School of Marine Studies at the University of Haifa, following encompassing geoarchaeological research at the port of Caesarea. "Tsunami events in the Mediterranean do occur less frequently than in the Pacific Ocean, but our findings reveal a moderate rate of recurrence," she says.

Technology brings new insights to one of the oldest Middle Eastern languages still spoken New technologies and academic collaborations are helping scholars at the University of Chicago analyze hundreds of ancient documents in Aramaic, one of the Middle East's oldest continuously spoken and written languages. Members of the West Semitic Research Project at the University of Southern California are helping the University's Oriental Institute make high-quality electronic images of Aramaic administrative documents. The texts were incised on clay tablets with styluses or inked on with brushes or pens. Contact: William Harms Public Release: 14-Oct-2009
A 200,000-year-old cut of meat New findings from the Qesem Cave archaeological dig in Israel indicate that during the Lower Paleolithic Period people prepared and shared meat differently than in earlier times, providing new clues into our evolutionary development, economics and social behaviors.

Rediscovering the dragon's paradise lost The world's largest living lizard species, the Komodo dragon (Varanus komodoensis), is vulnerable to extinction and yet little is known about its natural history. New research by a team of palaeontologists and archaeologists from Australia, Malaysia and Indonesia, who studied fossil evidence from Australia, Timor, Flores, Java and India, shows that Komodo Dragons most likely evolved in Australia and dispersed westward to Indonesia.

Scandinavians are descended from Stone Age immigrants Today's Scandinavians are not descended from the people who came to Scandinavia at the conclusion of the last ice age but, apparently, from a population that arrived later, concurrently with the introduction of agriculture. This is one conclusion of a new study straddling the borderline between genetics and archaeology, which involved Swedish researchers and which has now been published in the journal Current Biology.
