Canadian neuroscientists offer insights into the long-term effects of adolescent cannabis use — ScienceDaily

About one in five Canadian adolescents uses cannabis (19% of Canadians aged 15-19), and its recent legalization across the country warrants investigation into the consequence of this use on the developing brain. Adolescence is associated with the maturation of cognitive functions, such as working memory, decision-making, and impulsivity control. This is a highly vulnerable period…

Soil communities threatened by destruction, instability of Amazon forests — ScienceDaily

The clearing and subsequent instability of Amazonian forests are among the greatest threats to tropical biodiversity conservation today. Although the devastating consequences of deforestation to plants and animal species living above the ground are well-documented, scientists and others need to better understand how soil communities respond to this deforestation to create interventions that protect biodiversity…

Adding a carbon atom transforms 2D semiconducting material — ScienceDaily

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers at Penn State who say they can create new types of components for energy-efficient photoelectric devices and electronic circuits with this material. “We have successfully…
