Buddhist statue acquired by Nazis is space rock
NewScientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
One religious statue has a stronger connection than most to the heavens. An 11th-century carving from Mongolia of the Buddhist god Vaisravana was fashioned from a meteorite fragment, a chemical analysis shows. Its extraterrestrial origins make it unique in both religious art and meteorite science. More

Molecular fossils: new compounds from 4900-year-old wood
Chemistry World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
If you dug up a wooden artifact, how could you tell what type of tree it came from? French chemists have identified unique molecules from an ancient piece of oak that could hold the key. Pierre Adam and co-workers from the University of Strasbourg, France, used gas chromatography-mass spectrometry to identify triterpenoid molecules, which appear to be related to the natural product oleanane, in a 4900-year-old wood sample collected from river sediments.

Extreme climate change linked to early animal evolution
e! Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
An international team of scientists, including geochemists from the University of California, Riverside, has uncovered new evidence linking extreme climate change, oxygen rise, and early animal evolution. A dramatic rise in atmospheric oxygen levels has long been speculated as the trigger for early animal evolution. More

Old clam shells act like ocean sensors
Futurity    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Off the coast of Maine, clams can live up to 240 years, year after year adding another band to their shells, just like a tree adds another growth ring. In the colder waters of the North Atlantic near Iceland, the clams can live up to 500 years, recording even more information in what scientists call annual shell increments. More
