Come to a Fastlove event and you'll be talking to and meeting up to 25 dates in one night, each lasting at least three minutes.
Three minutes might not seem like much but you'd be surprised how easy it is to see if there's any chemistry with each of the people you meet.
To conduct radioisotope dating, scientists evaluate the concentration of isotopes in a material.
The number of protons in an atom determines which element it is, while the number of neutrons determines which isotope it is.
However, only one sample yielded an extended plateau over a wider particle size range and converging ages for the different centres.
