The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.
Ultra-trace radiation detection technique sets new global standard for measuring the nearly immeasurable
With each atom assigned a tonal signature based on its spectral signature, music can be a powerful tool for helping students understand atomic structure. Jill Linz is working toward synthesizing unique tones for each element to create an acoustic version of the periodic table. She will discuss her progress and the potential applications of the project at the 179th ASA Meeting, Dec. 7-10.
