No Eyes, But I still see

   BenUnderwood suffered reticular cancer when he was just three years because of that his eyes were removed and he lost his vision. As his visual system wasn’t fully developed, his brain started use the auditory system to guide him through the outside world. Time went by and he finally could develop a system to map the things around him; just by “Clicking” a noise with his tongue he uses the returned sound to create visual images, this system is called Echolocation.

 

   There are several animals such as, bats, dolphins and Amolops, than are capable to perceive the wave sounds projected from their selves, then this sounds are processed generating images from the surroundings; submarines also use the echolocation system to map the see bottom or scan for nearby objects. The principle of echolocation and several cases of people that have successfully achieved it, have leaded Scientifics to conceive the sonar implant, which is a device very similar to the cochlear implant (that replaces a damaged cochlea in the ear) this device is surgically implant into the brain cortex to send electrical signs with information; through this way the brain creates mental images using the variation between sounds reflected from different objects. 

 

   This new medical – technological advance would be the solution to deaf people, and to everyone that has visual problems, but do you think this invent will be applied for medical purposes in first place, or it will be so expensive that military industry will use it to increase its power?            

How do I look??

Thanks to mass media and science progress, every day we are becoming more acquaintance with how plastic surgery has become an alternative to make people feel happier with their bodies.

We are living in a time in which is common to hear that a celebrity have had a nose job, a liposuction done, or the breasts enlarged in the case of women. They go through these surgeries in order to fit into the celebrity world: runways, movies, magazines, etc. Whatever the reason might be, they have become fashion icons, and plastic surgery with cosmetic purposes has become trendy.

Now, imagine a situation in real life: a girl doesn’t realized that her lips are too thin until she has her nose fixed, then she realizes about some other “defect”, and here is where the vicious cycle starts. As you might notice, there is a narrow boundary between what can be normal and what can detonate the dependence to these procedures.

But, what is about plastic surgery that some people happen to be addicted to it?  Well, let us think! It gives people the opportunity to change almost any part of their body that is not pleasant for them; it is faster than doing exercise, letting alone the fact that there are some features that can’t be changed with any exercise or sport; and it completely can change a person’s life. Yet, can plastic surgery cannot change people’s feelings, manners, or personalities. Until what extent looking great has turned to be more important than being a great person from the inside out?
