Scientists spelunking in 11 Spanish caves have used an uncommon radioactive-decay method to date Paleolithic wall art, showing that some of the paintings may have been made by either Neanderthals or the earliest humans in Europe (Science, DOI: 10.1126/science.1219957). The dating method uses mass spectrometry to measure trace levels of uranium and thorium found in thin crusts of calcite that build up on the . . .
