When you think of all the advancements in medical technology, it can blow your mind. To prove that, we're bringing you the story of Brad Carter, a 39-year-old musician and actor. Carter has appeared on various TV shows, including "CSI." Carter had brain surgery recently, and you have to see it to believe it. Thanks to Vine, Twitter, and the power of the Internet, now you can.

Carter was diagnosed with Parkinson's disease in 2006. He started experiencing hand and eye tremors, which caused him to lose his ability to play the guitar. Doctors at UCLA Medical Center performed a deep brain-stimulation surgery, which involves implanting an electrode emitter to affected areas of Carter's brain. Surgeons had to awaken Carter during the surgery to make sure they were implanting the electrode emitter in the right part of his brain.

If you were to browse the iTunes music charts, it may surprise you to find that the top-selling song right now is by an artist you may have never heard of: Zach Sobiech's "Clouds" has landed at No. 1 with its inspirational message of hope and courage.

In 2009, when Zach was just 14 years old, he was diagnosed with osteosarcoma, a rare form of terminal bone cancer. In June 2012, he was told he had only a few months left to live. Sadly, Zach lost his battle with cancer on May 20. He had just turned 18 on May 3.

If creepy-crawly flying insects are not your thing, you might want to stop reading now: Brood II has arrived. What is it? It's the infestation of cicadas that takes over the East Coast every 17 years. The insects do not bite or sting and have no intention of causing pain or damaging crops. Their only goal is to mate.

In between infestations, they stay underground for 17 years, emerging only when the ground temperature reaches precisely 64 degrees. Their emergence was delayed this time because of the East Coast's uncharacteristically cool spring temperatures. The cicadas have not been seen in these quantities on the East Coast since 1996 (before that, they showed up in 1979). Brood II has already begun in Virginia and some other Southern states. Farther north, in New York and New England, the infestation is expected to begin shortly, as summer quickly approaches.

Cicadas are easily identified by their unmistakable loud chattering noise — which has been measured at up to 94 decibels.
