Prevent the spread of E. coli.
How can we help decrease carbon emissions, boost agricultural yields, and prevent E. coli from spreading? Anne Merrill, 17, of Old Greenwich, Connecticut, intends to find out, by studying the effects of integrating topsoil with biochar, a material gleaned from burning organic biomass.
Increase precision in breast cancer treatment.
