Underground cave dating from the year 1 A.D. exposed in Jordan Valley An artificial underground cave, the largest in Israel, has been exposed in the Jordan Valley in the course of a survey carried out by the University of Haifa. Professor Adam Zertal, who headed the excavating team, reckons that this cave was originally a large quarry during the Roman and Byzantine era and was one of its kind. Various engravings were uncovered in the cave, including cross markings, and it is assumed that this could have been an early monastery. Contact: Rachel Feldman Public Release: 18-Jun-2009

New 'molecular clock' aids dating of human migration history Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration -- even when no corroborating archaeological evidence exists. Contact: Jo Kelly Public Release: 4-Jun-2009
High population density triggers cultural explosions Increasing population density, rather than boosts in human brain power, appears to have catalyzed the emergence of modern human behavior, according to a new study by University College London scientists published in the journal Science. High population density leads to greater exchange of ideas and skills and prevents the loss of new innovations. It is this skill maintenance, combined with a greater probability of useful innovations, that led to modern human behavior appearing at different times in different parts of the world.

Ocean life in olden days: Researchers upend modern notions of 'natural' animal sizes, abundance Using such diverse sources as old ship logs, literary texts, tax accounts, newly translated legal documents and even mounted trophies, Census of Marine Life researchers are piecing together images -- some flickering, others in high definition -- of fish of such sizes, abundance and distribution in ages past that they stagger modern imaginations. They are also documenting the timelines over which those giant marine life populations declined. Contact: Terry Collins Public Release: 19-May-2009
Fire and water reveal new archaeological dating method Scientists at the University of Manchester have developed a new way of dating archaeological objects -- using fire and water to unlock their "internal clocks." Contact: Alex Waddington Public Release: 18-May-2009
The first evidence of pre-industrial mercury pollution in the Andes The study of ancient lake sediment from high altitude lakes in the Andes has revealed for the first time that mercury pollution occurred long before the start of the Industrial Revolution. University of Alberta Earth and Atmospheric Sciences Ph.D. student Colin Cooke's results from two seasons of field work in Peru have now provided the first unambiguous records of pre-industrial mercury pollution from anywhere in the world.

Researchers gain genome-wide insights into patterns of the world's human population structures Through sophisticated statistical analysis and advanced computer simulations, researchers are learning in greater detail about the genomic signatures of human population structures around the world. Looking at seven continental groups -- Africa, America, Central and Southeast Asia, East Asia, Europe, Middle East and Oceania, they found 18 axes of variation, some of which distinguished particular populations. They found variation patterns that correlated with geography in nearly every continental group. Contact: Leila Gray Public Release: 12-May-2009
New dinosaur species possible in Northwestern Alberta The discovery of a gruesome feeding frenzy that played out 73 million years ago in Northwestern Alberta may also lead to the discovery of new dinosaur species in Northwestern Alberta. University of Alberta student Tetsuto Miyashita and Frederico Fanti, a paleontology graduate student from Italy, made the discovery near Grande Prairie, 450 kilometers northwest of Edmonton.

eBay has unexpected, chilling effect on looting of antiquities, archaelogist finds Archaeologists held their breath more than a decade ago when the launch of eBay theoretically increased the market for looted archaeological treasures. In fact, writes the director of UCLA Cotsen Institute of Archaeology in the latest issue of Archaeology magazine, eBay hasn't increased looting, as originally feared. By creating a market for increasingly sophisticated fakes, eBay has actually had a dampening effect on the market for looted antiquities, writes UCLA archaeology professor Charles Stanish.

Princeton geoscientist offers new evidence that meteorite did not wipe out dinosaurs A Princeton University geoscientist who has stirred controversy with her studies challenging a popular theory that an asteroid wiped out the dinosaurs has compiled powerful new evidence asserting her position. Gerta Keller, whose studies of rock formations at many sites in the United States, Mexico and India have led her to conclude that volcanoes, not a vast meteorite, were the more likely culprits in the demise of the Earth's giant reptiles, is producing new data supporting her claim.

Native Americans descended from a single ancestral group, DNA study confirms After comparing DNA samples from people in dozens of modern-day Native American and Eurasian groups, an international team of scientists has provided robust evidence to support the theory that all Native Americans and Western Beringians trace a large portion of their ancestry to a single founding population, and that this population may have been isolated from other Asian groups prior to expanding into the Americas.
