For teen guys scaned

My four-year-old twins are similar in many ways — both are sociable, loving and cheeky — but a few contrasts are opening up. For instance, our son is more aware of time, endlessly curious about the future. Meanwhile our daughter is more determined to do things for herself. As a psychologist focused on personality and as their father , watching their characters emerge and develop fascinates me.

By Mark Prigg. The terrible teens has long been known to parents - but scientists have now found out why some teenagers are prone to taking huge risks as well as seeming antisocial. They say the research could explain why unintentional injuries are the leading cause of death for adolescents. They also say it could explain their seemingly antisocial behaviour - and say it is similar to addiction. New research from the Center for BrainHealth at The University of Texas at Dallas investigating brain differences associated with risk-taking teens found that connections between certain brain regions are amplified in teens more prone to risk. According to the CDC, unintentional injuries are the leading cause of death for adolescents. Compared to the two leading causes of death for all Americans, heart disease and cancer, a pattern of questionable decision-making in dire situations comes to light in teen mortality.

By Susannah Cahalan. If you know any teenagers this might not come as a surprise, but research has confirmed that risk-taking peaks during this exact moment in mid-adolescence. Knowing the neuroscience behind brain development should help us better understand, parent, teach and relate to those on the cusp of adulthood. A Harvard study scanned participants in MRI scanners and then alerted them that a peer was watching in reality, there was no peer.

Being able to peer into the human body without making a single incision is undeniably a major advance of modern medicine, and doctors and patients are taking full advantage of the latest techniques to scan our internal organs with CT, MRI, ultrasound and more. But as more studies show, that ability comes with a price. Between and , according to a study published in , the use of computed tomography CT scans nearly tripled, from 52 scans per 1, patients to scans per 1, patients. But CT scans generate those detailed images using small amounts of radiation, and while the absolute risk of that exposure is small, on a population level, increased reliance on the scans could drive a slight bump in cancer risk from CT.
