Attention Deficit in Teenage Boys: Who Would’ve Guessed?

A Brief Background

Attention Deficit Hyperactivity Disorder, also known as ADHD, is one of the most prevalent psychiatric diseases in childhood adolescence across the globe (Polanczyk et al, 2005). Children with ADHD find difficulties with their inattention, hyperactivity, and/or inability to control their impulses. These lifelong symptoms are caused by numerous neurotransmitter systems and various brain functions. Prenatal conditions such as low birth weight, prematurity, and prenatal exposure to alcohol and/or other toxins are external risk factors.

The Mystery of the Coral Triangle

The Enigma

Coral reefs are prime examples of thriving diversity, none more than the Coral Triangle, which is located in the ocean surrounding the archipelagos of the Philippines and other islands above Australia, pictured in the orange area of Figure 1. For hundreds of years, the Coral Triangle has fascinated scientists. This area contains more species of corals than any other area in the world, but scientists do not know how so many corals came to occupy the Coral Triangle. Recently, a group of scientists led by Danwei Huang came together to investigate four hypotheses on diversity in hopes to find which one is most accurate with regard to the corals of the region.
