The Science of Chewing

All of us have traits that simply make us, us; the way we walk, talk, or even smell are just as much a part of ourselves as eye color or height. Something not commonly listed, however, is the way we all chew. Scientists in the Netherlands have been hard at work learning about the science of chewing. At the cafeteria at Wageningen University, diners do not choose steak or fish, but rather are served crouton-sized cubes of silicone that taste similar to pencil erasers. These cubes can be used to determine jaw strength and patterns, providing scientists with a less messy approach to studying the unique abilities of everyone's jaw bones and muscles.

In addition to studying the routines in which we chew, Dr. Andries van der Bilt has paid even closer attention to the ways in which the jaw protects the teeth. He explains that when a crunchy particle is crushed, the jaw muscles activate a braking-like system, in which a split-second, unconscious decision is made to slow or adjust the force placed upon the teeth by the jaw. The muscles tense and relax in accordance with what they are processing and how the person is chewing. Van der Bilt also explains that teeth are not only smart, but also incredibly sensitive. The doctor explains that teeth can detect something as small as 1/25,000 of an inch, such as a grain of sand. 

Furthermore, van der Bilt continues about how swallowing food is processed and how humans may end choking. He elaborates that the voice box is what blocks food from being swallowed and that it moves when someone actually swallow. For this reason, it is dangerous to chew and talk at the same time. On the topic of safety, he also explains the risks of round, hard candy, hot dogs, and grapes as well-sized for blocking the esophagus and thus being choking hazards, especially for young children.

Click, Print, Gun: The Inside Story of the 3D Printed Gun Movement

With the recent mass shootings that have plagued our country in the recent years gun control has taken center stage in the recent topics of debate. With the government trying to crack down on the possession of "assault weapons" and remove them from society a new technology is going to change gun control forever.. I put "assault weapons" in quotations because the idea of saying that one gun is more deadly than an other just doesn't really make sense to me. A gun is a weapon no matter how many rounds it is able to fire so deeming one more dangerous than another is absurd. Anyway Cody R. Wilson is 25-year-old law student that is working to build semiautomatic weapons using 3D printers. In order to own an semiautomatic weapon you have to be registered with the federal government for a permit and the gun its self has to have a valid serial number on it. It's against the law to own one with out a serial number but there is nothing in that law that says you can not make the bottom receiver for your own personal use. The bottom receiver is essentially the gun it's self, it houses the trigger, the magazine, and the firing mechanism. The gun that he makes the bottom receivers for is the AR-15 which is a highly interchangeable gun, if you have the bottom receiver than you can make the gun look like anything you want. Wilson uses CAD files to create the receivers that his company Defense Distributed makes. All the other parts to the guns can be purchases online. His company also focus's on printing 30-round magazine clips in anticipation of Senator Dianne Feinstein's assult weapon ban bill that will limit the magazine size. Wilson goes on to say that whatever your thoughts are about gun control you can't deny that the 3D-printed gun movement is something that doesn't fin into the current legal framework. It's either excitign or scary, or maybe both, it's also interesting that you can go on his website and download the 3D blueprints of his gun parts and others for free. That is the beauty and the most frightening thing about this, as 3D printers become more readily available more and more people could be printing out their own gun parts. Just recently Cody received his license from the government to be able to sell his 3D printed gun parts but he says he won't.

A new tool to stop cybercrime

          “The recent barrage of high-profile cyber attacks has put many companies on edge, but it has also been a boon for developers of new security tools.” It is sounds interesting, isn’t it? In common sense, we always think that the computer intrusion is a horrible thing. And it is easy for us to feel that the cyber attacks only have harm for the society, whereas in this news there is a funny idea that is the network intrusion also has some advantages for some people, such as the developers of new security tools. It is really hard for us to think of this aspect when we get access to the cyber attacks, but this comment is really can let us convinced sincerely. I think there is a paradox that whether the developers like the hackers or not. If they face this issue as computer users, I think no one will like the cracker. On the other hand, they are the programmers, remember? They have to like these people in a special way because they need to work for money. By this token, we will ponder that we really can change our own ideas for the fortune in some cases. “Traditional firewalls filter out harmful data ‘packets’ and pass along legitimate ones.” We always say that the developments of science and technology are incredible, and the new products will rapidly out of date within a year. This speed of the development is a challenge for every product and company. Like the traditional firewalls, it is obviously that they can’t keep up with the trend of the times. Update just around the corner. Everything in the world counteracts and neutralizes each other, and we can believe that a powerful firewall will prevent the cyber attacks. We are willing to believe that Internet connections secured using next-generation firewalls will hit 35% in 2014 just like the statement in a recent Gartner report.
