This work investigates whether genetic makeup moderates the effects of education on health. Low statistical power and endogenous measures of environment have been obstacles to the credible estimation ...of such gene-by-environment interactions. We overcome these obstacles by combining a natural experiment that generated variation in secondary education with polygenic scores for a quarter-million individuals. The additional schooling affected body size, lung function, and blood pressure in middle age. The improvements in body size and lung function were larger for individuals with high genetic predisposition to obesity. As a result, education reduced the gap in unhealthy body size between those in the top and bottom terciles of genetic risk of obesity from 20 to 6 percentage points.

The importance of facial esthetics to the practice of orthodontics has its origins at the beginning of our specialty. In 1900, Edward H. Angle believed that an esthetic or a “harmonious” face ...required a full complement of teeth, but many who came after him questioned this notion. In the 1930s, the development of cephalometrics laid the foundation for studying growth and development, treatment effects, facial forms, and esthetics. By the 1950s, the importance of diagnosing and planning treatment for an esthetic result was established, but the measurement of soft tissue variables was lacking, and this became an important area of research. In the 1970s, researchers were looking at the stability of hard tissue changes over time, and they were also interested in how the soft tissues change with age. Although the early studies of esthetics in orthodontic treatment focused on how clinicians viewed their patients, changing demographics and cultural attitudes led researchers to look more seriously at consumer preferences and the public's attitudes. Their findings—that consumers preferred fuller lips—led to a swing back toward nonextraction treatment. Expansion appliances and molar distalization techniques became popular, and surgical procedures to obtain more ideal esthetic results became more common. Since the 1990s, advances in computers and technology have allowed us to study, predict, and produce esthetic results previously thought unattainable. Today, more so than at any other time in our specialty, we have the ability to provide esthetic results to our patients.
We introduce multi-trait analysis of GWAS (MTAG), a method for joint analysis of summary statistics from genome-wide association studies (GWAS) of different traits, possibly from overlapping samples. ...We apply MTAG to summary statistics for depressive symptoms (N
= 354,862), neuroticism (N = 168,105), and subjective well-being (N = 388,538). As compared to the 32, 9, and 13 genome-wide significant loci identified in the single-trait GWAS (most of which are themselves novel), MTAG increases the number of associated loci to 64, 37, and 49, respectively. Moreover, association statistics from MTAG yield more informative bioinformatics analyses and increase the variance explained by polygenic scores by approximately 25%, matching theoretical expectations.
