There is always something new happening in the world of science. In fact, there are so many new scientific discoveries and inventions, that its virtually impossible to stay abreast of all the new information. Here are a few really cool new inventions that are under development.Using flying beetles for search and rescueNew research, funded by the Defense Advanced Research Projects Agency (DARPA), has demonstrated how flying beetles could one day be used surveillance purposes or for search-and-rescue and similar missions.Michel Maharbiz is trying to take advantage of the beetle’s natural abilities by melding insect and machine.  The team has wirelessly controlled a giant flower beetle with implanted electrodes and a radio receiver on its back. With a nearby computer they can send wireless signals to the beetle including commands to take off, hover in place, turn left, and turn right and land.Osci b minor scale llating electrical pulses delivered to the beetle’s optic lobes trigger takeoff, while a single short pulse ceases flight. Sending electrical signals to the left or right basilar flight muscles make the animal turn right or left, respectively.The reason behind the selection of the giant flower beetle is that it is large and can carry a heavy payload.  It would need to carry a camera and heat sensor for search-and-rescue missions for example.Artificial gecko feet using carbon nanotubesScientists have been trying to duplicate the adhesiveness of gecko feet for years without success.  Liming Dai, a professor at the University of Dayton, and Zhong Wang, director of the Center for Nanostructure Characterization at Georgia tech, have developed a new adhesive that closely mimics the structures on gecko feet. Gecko feet are covered with millions of micro-scale hairs which branch into even smaller hairs.
