Gold Coin Discovered in Slovenia
ČRNOMELJ, SLOVENIA—STA reports that archaeologists excavating one of 15 Celtic burials at the Pezdirčeva Njiva site, which is located in southeastern Slovenia, discovered a bronze belt adorned with a gold coin dating to the third century B.C. The coin bears images of the goddesses Nike and Athena and is thought to be a copy of a Greek coin known as an Alexander the Great stater. “A golden coin as such is a rare find in Slovenia,” said Lucija Grahek of the Academy of Sciences and Arts. “As far as I know, this is the third golden coin found at Slovenian sites, and as it seems, the oldest.” Some organic material making up the belt was also preserved.

Mammoth Tusk “Tiara” Discovered in Denisova Cave
NOVOSIBIRSK, RUSSIA—According to a report in The Siberian Times, archaeologists have found a 50,000-year-old piece of worked woolly mammoth tusk in the southern gallery of Denisova Cave. Alexander Fedorchenko of the Novosibirsk Institute of Archaeology and Ethnography suggests the curved ivory object is a fragment of an ornament whose large size indicates it was worn by a Denisovan man. A cord would have been threaded through holes in either end of the piece and then tied around the wearer's head in order to keep his hair out of his eyes. There is evident wear and tear on the artifact, which was eventually discarded. Such ivory “tiaras,” as they are called, have been found in other parts of Siberia, but those decorated items were created between 20,000 and 28,000 years ago by modern humans. The Densiovan tiara suggests the tradition could be older than previously thought. For more, go to “Denisovan DNA.”

New Strain of Plague Found in Neolithic Remains in Sweden
MARSEILLE, FRANCE—Live Science reports that a new strain of Yersinia pestis, the bacteria that causes plague, has been identified in human remains from a Neolithic tomb in Sweden by a team of researchers led by biologist Nicolás Rascovan of Aix-Marseille University. The bacterial DNA came from the dental pulp of a 20-year-old woman who is thought to have died about 4,900 years ago from the deadly pneumonic form of the disease. Based upon comparisons with other strains of Yersinia pestis, Rascovan and his colleagues suggest this one diverged about 5,700 years ago, making it the oldest known strain of plague. It had been previously thought that plague first traveled to Europe from the Eurasian steppe as people migrated west and replaced European farmers, but the age of the plague strain found in Sweden suggests that European farmers may have already suffered from the infection and been in decline when the Eurasians arrived. Karl-Göran Sjögren of the University of Gothenburg said the presence of the plague in Sweden could reflect the growth of bigger settlements and poor sanitary conditions, use of wheeled transport, and increased contact among groups of people through trading networks in the Neolithic world, all of which may have helped spread the pathogens. The scientists have not yet found direct evidence of plague in any of these large Neolithic settlements, however. For more, go to “A Parisian Plague.”

4,000-year-old olive seeds unearthed in SE Turkey
When Augustus Caesar rose to become the first Roman emperor, in 27 BC, the seeds recently unearthed by Turkish archeologists were already 2,000 years old.

Mantle neon illuminates Earth's formation
The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, according to research published in the journal Nature. Apart from settling Earth's origins, the work could help in identifying extrasolar systems that could support habitable planets.

Greenland ice sheet melt 'off the charts' compared with past four centuries
Surface melting across Greenland's mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research published in the journal Nature. The study provides new evidence of the impacts of climate change on Arctic melting and global sea level rise.
Large rivers form on the surface of Greenland each summer, rapidly...

Scientists discover possible mantle mineral
Scientists long believed that the lower mantle was composed of Bridgmanite (Mg,Fe)SiO3 and magnesiowüstite (Mg,Fe)O, in which Fe2+ dwells. This view changed when experiments showed that Fe2+ simply can't exist at the pressure and temperature of the lower mantle. What is present is Fe3+. The two phases (Mg,Fe)SiO3 and (Mg,Fe)O both shed Fe2+ and, in turn, MgSiO3 and MgO remain. However, what...

Soft tissue shows Jurassic ichthyosaur was warm-blooded, had blubber and camouflage
An ancient, dolphin-like marine reptile resembles its distant relative in more than appearance, according to an international team of researchers that includes scientists from North Carolina State University and Sweden's Lund University. Molecular and microstructural analysis of a Stenopterygius ichthyosaur from the Jurassic (180 million years ago) reveals that these animals were most likely warm-blooded, had insulating blubber and...

Under the microscope, a Botryllus colony looks like a bouquet of flowers, although in reality each “petal”
is a separate organism with its own heart, gills, digestive system, brain and blood...

A detailed look at the microorganisms that colonize, and degrade, a 400-year-old painting
What's a feast for the human eye may be a literal feast for microorganisms that colonize works of art, according to a new study in the open-access journal PLOS ONE by Elisabetta Caselli of the University of Ferrara, Italy, and colleagues. The researchers characterized the microbial community on a 17th century painting and showed that while some microbes destroy such works of art, others might be employed to protect them.
