Pollen carbon dating
Due to its global influence and military capabilities, India has also gained a permanent seat on the UN Security Council.
He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.A barrage of tests proves that the marijuana possessed potent psychoactive properties and casts doubt on the theory that the ancients only grew the plant for hemp in order to make clothing, rope, and other objects. Lead author Ethan Russo told Discovery News that the marijuana "is quite similar" to what's grown today.(Source) In 2007, a 5,000-year-old piece of chewing gum, the oldest ever discovered, was found by a British archaeology student in Finland.I learned a lot in such a short span of time, Thanks!Radiocarbon dating of bulk sediments has been the standard method for establishing chronologies in the studies of lake sediment cores which have contributed significantly to our knowledge of late Quaternary paleo-environments.In this study, we demonstrate for the first time the radiocarbon dating of pollen concentrate samples by accelerator mass spectrometry.
The dates obtained by this method should provide more reliable radiocarbon chronologies for paleo-environmental studies than have been obtainable by bulk sediment dating.
Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology, and even biomedicine.

Stuffed with grass, perhaps as an insulator or an early shoe tree, the 5,500-year-old moccasin-like shoe was found exceptionally well preserved—thanks to a surfeit of sheep dung—during a 2010 dig in an Armenian cave. S.), the shoe was likely tailor-made for the right foot of its owner. C., during Armenia's Copper Age, the prehistoric shoe is compressed in the heel and toe area, likely due to miles upon miles of walking.

A couple of flutes made from bird bone and mammoth ivory came from Hohle Fels Cave in Germany, which contains early evidence of the occupation of Europe by modern humans, or Homo sapiens.
