A new study from Virginia Tech shows football helmets can be designed to reduce the risk of concussions.
Between 2005 and 2010, more than 18 hundred football players from Virginia Tech and six other colleges and universities around the country wore helmets equipped with sensors to measure the biomechanics of head impacts. The players either wore a Riddell VSR4 or Riddell Revolution helmet and the sensors recorded over one million hits. Tech researcher Steve Rowson says the Revolution helmet’s padding was 40 percent thicker than the other helmet.
Plenty of people spend at least part of their time at college sleeping through class, but at Washington and Lee University, students have the chance to enroll in a course where they’ll learn why.
Assistant Professor Natalia Toporikova was invited to design an undergraduate course that would teach students the basics of science: how to interpret studies, how to develop a hypothesis and test it. What better way, she thought, than to study the subject of sleep? It was not her decision to schedule that class at 8 a.m.
Virginia Tech is one of six sites that will test drones as part of push to integrate them into the nation’s airspace in the next few years.
The Federal Aviation Administration selected 6 public entities to test unmanned aerial vehicles, known as drones. Virginia Tech will look at safety, from technical risks, to other potential failures in the remotely piloted planes.
