A 3,775-year-old log found in Canada had barely lost any of its carbon content since being buried, indicating "wood vaulting" is a viable means of carbon storage.

Some of that carbon-12 gets exposed to cosmic radiation and turns into carbon-14, which has eight neurons. Carbon-14 is radioactive, with a half-life of 5,700 years. So what makes this useful? Plants.

Carbon has three natural isotopes: carbon-12, carbon-13, and carbon-14. Carbon-14 is a rare version of carbon with eight neutrons. It is radioactive and decays over time.

Radiocarbon dating, or carbon-14 dating, is a scientific method that can accurately determine the age of organic materials as old as approximately 60,000 years. First developed in the late 1940s at ...

Since carbon-12 doesn’t decay, it’s a good benchmark against which to measure carbon-14’s inevitable demise. The less radioactivity a carbon-14 isotope emits, the older it is.

A 3,775-year-old log unintentionally discovered under a farm in Canada may point to a deceptively simple method of locking climate-warming carbon out of the atmosphere for thousands of years ...
