evidences.evidence: In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research.

evidences.evidence: Stable isotopes of oxygen (δ18O) and carbon (δ13C) are recorded well in speleothems, giving high-resolution data that can show annual variation in temperature (oxygen isotopes primarily reflect rainfall temperature) and precipitation (carbon isotopes primarily reflect C3/C4 plant composition and plant productivity, but the interpretation is often complicated).
