Catherine Matacic—online news editor for Science—talks with Sarah Crespi about how geoengineering could reduce the harshest impacts of climate change, but make them even worse if it were ever turned off.

Sarah also interviews Augustine Kong of the Big Data Institute at the University of Oxford in the United Kingdom about his Science paper on the role of noninherited “nurturing genes.” For example, educational attainment has a genetic component that may or may not be inherited. But having a parent with a predisposition for attainment still influences the child—even if those genes aren’t passed down. This shift to thinking about other people (and their genes) as the environment we live in complicates the age-old debate on nature versus nurture.
