Accelerator mass spectrometry measures the amount of carbon-14, or radiocarbon, present in a sample, which can be used to calculate its age.

Around the world, only about 100 facilities house this equipment.

Once an organism dies, it stops taking in carbon-14.

The carbon-14 it contained at the time of death decays over a long period of time, and the radioactivity of the material decreases.

SCAR offers significant time and cost savings compared to the standard approach for carbon dating and could be useful for a host of other applications such as measuring emissions from fossil fuels or certifying the amount of biogenic content in biofuels.

A new spectroscopic technique offers ultra-sensitive optical detection of radiocarbon dioxide.

The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.

The Mayan calendar used 3114 BC as their reference.

The instrument, which uses a new approach called saturated-absorption cavity ring-down (SCAR), is described in The Optical Society's journal for high impact research, .

More recently is the radiocarbon date of 1950 AD or before present, BP.
