Mobile and interactive media use by young children: The good, the bad and the unknown
Mobile devices are everywhere and children are using them more frequently at young ages. The impact these mobile devices are having on the development and behavior of children is still relatively unknown. In a commentary in the journal Pediatrics, researchers review the many types of interactive media available today and raise important questions regarding their use as educational tools, as well as their potential detrimental role in stunting the development of important tools for self-regulation.

Team discovers key to preventing blindness and stroke devastation
Research led by Nicolas Bazan, MD, PhD, Boyd Professor, Ernest C. and Yvette C. Villere Chair of Retinal Degeneration Research, and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered gene interactions that determine whether cells live or die in such conditions as age-related macular degeneration and ischemic stroke. These common molecular mechanisms in vision and brain integrity can prevent blindness and also promote recovery from a stroke. The paper is published online in Cell Death & Differentiation, a Nature journal.

Understanding the reinforcing ability of carbon nanotubes
A new article explores what is preventing the reinforcing ability of carbon nanotubes from being used in a ceramic matrix. Ever since their discovery, carbon nanotubes (CNTs) have been considered the ultimate additive to improve the mechanical properties of structural ceramics, such as aluminum oxide, silicon nitride and zirconium dioxide. Yet despite the remarkable strength and stiffness of CNTs, many studies have reported only marginal improvements or even the degradation of mechanical properties after these super-materials were added.

Heat waves becoming more prominent in urban areas, research reveals
The world’s urban areas have experienced significant increases in heat waves over the past 40 years, according to new research. These prolonged periods of extreme hot days have significantly increased in over 200 urban areas across the globe between 1973 and 2012, and have been most prominent in the most recent years on record.

Biomaterial coating raises prospect of more successful medical implants
A novel, bacteria-repelling coating material that could increase the success of medical implants has been created. The material helps healthy cells 'win the race' to the medical implant, beating off competition from bacterial cells and thus reducing the likelihood of the implant being rejected by the body.
