Tree rings reveal ancient solar storms, helping scientists predict and prepare for future events that could disrupt ...

They were also able to perform DNA, chemical and radiocarbon analyses of the tree, revealing new clues about its origins, according to a study published Sept. 10 in the journal Communications Biology.

Once it had shed, the team used radiocarbon dating on the organic matter to estimate the plant’s age and found the specimen dated to between AD 993 and 1202. Not long after, the tree began to sprout ...

Samples taken from artifacts in the museum collections were used to test the accuracy of radiocarbon dating, since archaeologists already knew their ages by tree-ring dating and other evidence. The ...

Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results. Direct Dating of Wood Cross-dating determines the age of ...

Spikes in radiocarbon levels can be seen in tree rings from the last 40,000 years. Sure enough, the timing of supernovae that occurred relatively close to the Solar System in the last 40,000 years ...

Ancient tree remains and pollen discovered in the Falkland Islands reveal a past rainforest environment, radically different ...

the breakthrough technique ushered in the “radiocarbon revolution” and impacted fields from archaeology to climate science—forever changing our picture of human history. Carbon dating is based on the ...

ANSTO scientists, Dr. Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14 C) is produced, retained and lost in the top ...

The principle behind these procedures lies in the determination of a radiocarbon age and its comparison with the known age which, in the case of tree rings, is established through ...
