Getting tired of Facebook? Or perhaps you want to switch to a network that takes a more active role in protecting your privacy. If you are looking for something different in the social networking scene, you may be in luck. Internet Giant Google just announced their latest project, “Google Plus (+).” Currently in invitation only stage, Google Plus is a social network with some promising features to separate it from the competition. Take a look at the videos below to gain a better understanding of what Google is trying to achieve.
In 1978 my grandfather was involved in a severe motorcycle accident while travelling to work. Unfortunately, transportation safety wasn’t much of a concern as it is now (especially true in India) and a few individuals wore helmets while riding their bikes. Needless to say, the force from the collision threw my grandfather off his bike and against a roadside curb. Without protection from an helmet, his head directly took a majority of the impact from the collision. Although my grandfather was lucky to not have experienced any coning in areas critical for respiration and other life supporting activities, the same could not have been said for the cerebellum. When his head met the curb, the portion that received direct impact was the brainstem region (the cerebellum is located right behind the pons of the brainstem). In turn, a lesion was formed in the area and resulted in our topic of discussion today: Cerebellar ataxia.
Have you ever wondered how the hard drive in your computer works? To my surprise, almost all the tech savvy individuals I spoke to today could not provide a satisfactory answer to this question despite being able to identify almost all the internal components that make up a platter based hard disk. Luckily for us, Bill Hammack from the Department of Chemical and Biomedical Engineering at the University of Illinois tackles this topic in his latest video.
