The study was conducted by researchers from the University of Quebec at Montreal, Laval University, the University of Alabama, the University of Montreal, and University College Dublin.
"Aggressive behavior in middle childhood is at least partly explained by genetic factors, but genetic influences on behavior usually don't operate independently of environmental influences," notes Mara Brendgen, professor of psychology at the University of Quebec at Montreal, who led the study.
Researchers studied 217 Canadian identical and fraternal twin pairs at age 7 to delve into the interplay between nature and nurture involving the source of aggression in the children. Twin pairs weren't in the same classrooms, but had different teachers and different classmates. Classmates rated the twins' level of aggressive behavior and the extent to which they were victimized by peers. The twins' teachers rated the quality of their relationship with each twin. Genetic effects on aggression were estimated by comparing the similarity in behaviors of identical and fraternal twin pairs.
The study found that children who were genetically vulnerable to being aggressive were more likely to be victimized by their classmates than others. However, these children were protected from acting aggressively and being the target of other children's aggression if they had a very good relationship with their teacher—a relationship that was warm and affectionate and involved open communication.
"Children's relationships with teachers and with peers in school play a critical role in shaping their social-behavioral development," notes Brendgen. "Our study found that a good relationship with the teacher can protect genetically vulnerable children from being aggressive and, in consequence, from becoming the target of other children's aggressive behavior."
The findings can inform interventions aimed at addressing children's aggression, and can also be used in teacher-training efforts.
The study was supported by the Social Sciences and Humanities Research Council of Canada, the Fonds Concerté pour l'Aide à la Recherche, the Fonds Québécois de la Recherche sur la Société et la Culture, the Canadian Institutes of Health Research, and the Fonds de Recherche en Santé du Québec.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
