Trek Tech
We're getting closer and closer to living in the world Star Trek creator Gene Rodenberry envisioned fifty years ago. For a little perspective, when Star Trek first aired in 1966, we had to change the channel by hand if we didn't want to watch it. We used rotary phones lashed to the wall with hard wires. And sending humans or robots to foreign worlds was still a distant dream.

Now Star Trek tech is a big part of today's world. Cell phones, scalpel-free surgery and probes that gather and relay information about alien planets are just a few of the predictions made by the televison series. And now, scientists are getting closer to developing a "cloaking device." Researchers at the University of Texas at Austin announced that they successfully cloaked a 3-D object standing in free space from microwave view.

Scientists cloaked a cylindrical object in plasmonic metamaterials, which scatters microwaves instead of allowing them to bounce back to detectors and Voila! the object was invisible. The next challenge is to adapt the technique to cloak larger objects from visible light--and the human eye. Who knows? Maybe one day we'll send a cloaked spaceship to explore "strange new worlds" and even observe a distant species before making First Contact.
