Are your kids and grandkids spending too much time on video games and Pokémon Go (C&EN, Aug. 1, page 72)? Professional molecular modeling software called ChemSketch 2015 is available as a free download (it has no molecule dictionary but is still very useful). Homeschool parents as well as teachers, kids, and grandkids can use ChemSketch to create space-filling and ball-and-stick molecular models. The ChemSketch software can be used at any grade level, starting with fourth grade and continuing until introductory chemistry.

Aug. 29, page 6: A Science Concentrate about an improved synthetic route to ryanodol incorrectly stated that Pierre Deslongchamps’s group at the University of Sherbrooke first reported a synthesis of ryanodol in 1990. The synthesis was actually first reported in 1979 (Can. J. Chem., DOI: 10.1139/v79-547). The full paper on the synthesis was published in 1990.
