Nanotechnology: Creating the perfect human?
How would you feel if you had the choice of having billions of tiny robots injected into your body? A pretty unpleasant thought, am I right? What if I told you that these tiny robots could repair any mutation you may have in your DNA? Sound far-fetched? Well, scientists have been making huge breakthroughs in this! It’s called nanotechnology. These small robots are like tiny computers that are coded to attach to specific cells in your body and carry them from point A to point B. These tiny robots, 1-100nm in size (or 1 and 100 billionth of a meter!), are like transporters; they pick up the target cell at point A and move it to point B. Point B can be anything from the trash, (cell death) if the cell is not needed anymore, to another part of the body where the cell is needed. They also have the ability to reprogram a cell’s biology. If more of one cell is needed in a particular area it can bring that cell to the specified area and “tell” it to replicate. Basically, nanotechnology will eventually perfect every single cell in your body.
Dolphins Prove Themselves (Yet Again)
Dolphins are pretty amazing creatures, to put it simply. In Douglas Adams' The Hitchhiker's Guide to the Galaxy, the dolphins knew of the Earth's impending doom well before people did ("So long, and thanks for all the fish!"). In addition to their extraordinary cognitive abilities, they have highly developed and extremely interesting social skills (such as killing for pleasure).
Speaking of killing, let's discuss sharks. Contrary to popular belief, sharks are only dangerous if you give them reason to be. During the course of my summer internship, I've seen many sharks, from toothless dogfish to five foot long juvenile tiger sharks. All have been docile; they tend not to try to attack unless you poke them hard enough (in an out of water case). But, say you happened to be standing in front of the aforementioned tiger shark's mouth and poked it, and it flailed and bit your leg. You'd probably scream in pain, bleed, and need to see a doctor right away.
Now consider an in water encounter between a dolphin and a shark. The dolphin could just be swimming normally and pass a shark. The shark could misinterpret the dolphin swimming nearby as a threat, and attack, leaving a 3 centimeter deep, 30 centimeter long, 10 centimeter wide wound. Not only would the dolphin not feel pain from this, but it would continue feeding, swimming, and behaving normally! Even more amazingly, the wound would heal over time with little scarring or changes in overall contour! More
Down and Out? Try a Tylenol.
We’ve all experienced the distinct effects of a nice analgesic, whether it was amidst a debilitating rhinovirus, or after one of those over-did-it workouts: the ease of movement, the decrease in physical stress, and most importantly the shift of focus from your pain to reality. We should all be thrilled then, to learn that on top of reducing physical symptoms of pain, drugs normally taken to alleviate minor aches and pains could actually work to reduce the emotional twinge of social rejection, according to recent research.
The study, powered by C. Nathan DeWall of the University of Kentucky, gave volunteers either acetaminophen or placebo, and then subjected them to a game of virtual ball-toss. Over time, subjects were gradually rejected from the game. Those who had been given the analgesic demonstrated signs that they experienced fewer feelings of rejection, as was inferred through brain imaging of the anterior cingulate cortex, an area associated with feelings of emotional pain and desperation.
DeWall and his colleagues also demonstrated the effects of acetaminophen on a person’s moral judgment. When confronted with typical ethical quandaries, such as whether or not it’s right to sacrifice one person to ensure the safety of others, subjects showed less hesitancy in declaring their moral choice.
Though these researchers are quick to point out that no one should expect to correct their emotional problems with such a common drug, I think it’s important to realize just how effective a small chemical push towards recovering from a refusal could be. So often, when met with defeat or failure, it’s our natural reaction to dwell on our lack of fortune, to lose confidence or determination, or simply to become angry and resentful. In a world where there’s a constant competition for success, our failings become exaggerated, and our emotional anguish increases. As more and more Americans (over 27 million) elect to take strong psychotropic prescription antidepressants, it’s comforting to think that a slight mood improvement can be afforded through more mild drugs like Tylenol. Of course, acetaminophen has its own dangers, and causes liver failure if abused. Still, whether one is applying to graduate schools and jobs, or asking someone out on a date, a little Tylenol couldn’t hurt.
