In his Democracy Da

In his Democracy Day speech,You know the type We may joke about Snooki’s bad habits, In fact CTE has been found in 96% of former NFL players examined posthumously One year ago avid football fan Raymond Colello watched Wes Welker a wide receiver for the Denver Broncos go down with the second game-ending concussion of his career “I began lamenting the fact that concussions may ultimately destroy football itself” said Colello a neuroscientist at Virginia Commonwealth University in Richmond at a session here on Saturday at the Society for Neuroscience’s annual conference “And at that point like all people watching football on Sunday I went out to my refrigerator for another beer” Staring at the magnets decorating the refrigerator door he had an idea: What if you put such objects inside helmets “You need some kind of force field around these guys” he recalls thinking “Maybe a repulsive force would possibly work” Roughly 60% of concussions in football are caused by head-to-head collisions The material now packed inside traditional helmets reduces concussions by deflecting some of the energy after a collision occurs According to Colello magnets could extend the impact zone beyond the hard shell of players’ helmets slowing the collision down before it occurs thus reducing the overall g-force that a player experiences—just like brakes on a car If a driver slams on the brakes just before it smashes into a wall the impact will still occur but at a slower speed decreasing the g-forces that the driver experiences Colello wants to add palm-sized magnet inserts made from the rare earth element neodymium into the front and sides of helmets The removable inserts follow the curvature of the helmet so players can’t accidentally hit the field with the wrong pole facing outwards According to Colello they could increase the price per helmet by as little as $100 Neodymium magnets are lightweight but they still have a repulsive force-to-weight ratio of 300-to-1; a 1-pound (045-kilogram) magnet could repel at least 300 pounds (136 kilograms) of force Colello’s magnet inserts would weigh in at half to three-quarters of a pound each He tested the magnets with a standard drop test—the same test helmet manufacturers use to evaluate helmet strength He attached the magnets to 10-pound (45-kilogram) weights dropped one weight from various heights and measured the g-force at the site of impact with the second stationary weight Colello found that the magnets could reduce 140-g hits down to 88 g’s—a full 8 g’s lower than standard helmets—and 40 g’s down to a mere 3 The reduction of collisions with low g-forces is just as important he says given that repeated subconcussive hits can add up over time and lower the threshold for a concussion until a relatively mild blow is enough to cause a disproportionate amount of damage The standard drop test is a good approximation of linear forces or direct hits but out on the field most hits are not head-on Indirect hits produce rotational forces that send the brain twisting inside the skull which can cause even more damage “We really have to look at both linear forces or direct hits as well as rotational forces” Colello said after the presentation To do that he plans to send two Humanetics Hybrid II headforms (read: crash test dummies) equipped with magnetized helmets and accelerometers careening down a zip line toward each other By monitoring what happens when the crash-test dummies meet Colello can be sure that the magnets aren’t just replacing linear forces with rotational ones “We don’t want to trade concussions with spinal cord injuries” he says The magnets would complement rather than replace current force reduction technologies in helmets according to Colello who plans to begin the zip line tests by the end of the year and if the data prevail proceed to human testing in just 6 months “The best helmets now are about as good as they are going to get” says Stefan Duma a biomedical engineer at Virginia Polytechnic Institute and State University in Blacksburg “In order to make any big advancements we’re going to need outside-the-box thinking [Colello’s] technology in theory extends the impact outside the helmet It gives you a longer duration [of impact]” says Duma who created the five-star rating system for commercially available helmets Still there are several challenges to address before the helmets reach the playing field Duma cautions The magnets won’t do any good if a player’s head collides with a knee a shoulder or the ground And to help in head-to-head collisions the technology has to be universally adopted “It has to be implemented by everybody You can’t have just one team have it” Colello says “I mean you certainly can but it won’t have any effect at all”LONDON US-led airstrikes have failed to slow the number of ISIS attacks and its defiant militants are now racking up a higher body count than ever before according to data provided exclusively to NBC News Analysis of IHS Jane’s Terrorism and Insurgency Center’s (JTIC) database shows the current face and pace of the group’s battle for Syria and Iraq Data showed that ISIS massively stepped up attacks after conquering the Iraqi city of Mosul on June 10 and has stepped them up further since airstrikes were launched in August. 21, With his cooperation, for example, I starred in my first short film (by Konstantin Brahznik) and we shot it during my first winter break at UVA. there were nine cases of herdsmen invading communities in Benue state alone and more than 190 people were killed. and then I became Batman.com.
