The Amazing Gecko-Man: a superhero future made possible by probable science
There's no superhero origin story that begins with a bite (or a lick?) from a gecko. Plain 'ol wall climbing powers are, it seems, just not as sexy as wearing skintight suits, slinging webs and crawling up buildings. But if a few bright minds at the University of Southampton have anything to say about it, we could soon find ourselves walking like real-life lizard people (V, anyone?) and suctioning onto various surfaces using the managed properties of light. Lead researcher John Zhang and his UK team have predicted the existence of a force more powerful than gravity and the short-range pull of the Casimir effect, whereby plasmons (electromagnetic waves) captured on a metamaterial and the electrons on a metal resonate and form a bond of attraction. The resultant particle field is supposedly strong enough to "overcome the Earth's gravitational pull" and could even be used to alter the reflectivity of a material. Obvious military and aerospace applications aside, this invisible adhesive could also make its way into our everyday lives -- they just need to need to prove that it, y'know, actually exists first.
Secrets of levitation cracked by Scottish researchers?
Try not to get too frenetic here, but a couple of gurus at the University of St. Andrews in Scotland have reportedly created an "incredible levitation effect by engineering the force of nature which normally causes objects to stick together." In layman's terms, the scientists have devised a way to reverse the phenomenon known as the Casimir force so that it "repels instead of attracts." Ultimately, the discovery could lead to "frictionless micro-machines with moving parts that levitate," and in theory, devices could be created to transport humans. Do realize, however, that individuals in this team have also "showed that invisibility cloaks are feasible," so we're not counting ourselves amongst the faithful just yet.[Thanks, James][Our readers have let us know that this article's headline bore some similarities to other articles on the same topic -- though purely coincidental, in the interest of further differentiating the post we've edited it to a small degree. -Ed.]
