15hGraphene nanoribbons (GNRs) are narrow and long strips of graphene with widths below 100 nm. GNRs that have smooth edges, a sizable bandgap and high charge carrier mobility could be highly valuable for a wide range of electronic and optoelectronic applications. So far, however, engineers have not yet introduced a method to prepare these useful components on a large scale.

Cosmopolitan morality trades off in-group for the world, separating benefits and protection [Psychological and Cognitive Sciences]
12hGlobal cooperation rests on popular endorsement of cosmopolitan values—putting all humanity equal to or ahead of conationals. Despite being comparative judgments that may trade off, even sacrifice, the in-group’s interests for the rest of the world, moral cosmopolitanism finds support in large, nationally representative surveys from Spain, the United Kingdom,…
The cost of correcting for error during sensorimotor adaptation [Neuroscience]

Researchers explore what drives animal infanticide
16hAt the end of the 1970s, infanticide became a flashpoint in animal behavioral science. Sociobiologist Sarah Hrdy, then a Harvard Ph.D. student, shared her observation in her published thesis that whenever a new langur male entered an established colony, infants would either begin to disappear or show evidence of wounds. Hrdy concluded this was done to eliminate the progeny of rivals and free up no

How new leaders build or lose trust over time
16hThe goal of any new leader is to quickly establish a high level of trust and credibility with the team. After all, numerous studies have shown that trust in leadership is linked to higher individual and team performance. However, that might not be the best strategy for long-term success, according to a new study from Olin Business School at Washington University in St. Louis.
