(PhysOrg.com) -- By morphing and repositioning a small aircraft's vertical tail to resemble the cranial crest of a pterosaur, researchers have shown that the aircraft's turn radius can be reduced by 14%. The ability to make ...
(PhysOrg.com) -- Devices that harvest ambient energy from the surrounding environment have become popular since, for some applications, they eliminate the need for batteries that must constantly be replaced. One of the most ...
(PhysOrg.com) -- Although the lungless salamander and some frog species have developed ballistic tongues, the chameleon's ballistic tongue is the fastest, the longest, and the one that can catch the heaviest prey. A chameleon’s ...
(PhysOrg.com) -- Although it's difficult to predict what the future Internet will look like, it's probably safe to say that certain trends we've seen during the past decade will continue. This means that the Internet will ...
(PhysOrg.com) -- When it comes to finding the single best tool for building, digging, grasping, drawing, writing, and many other tasks, nothing beats the human hand. Human hands have evolved over millions of years into four ...
(PhysOrg.com) -- Many trees disperse their seeds by releasing "helicopters," those single-winged seeds that are also called "samaras." As these seeds fall to the ground, their wing causes them to swirl and spin in a process ...
(PhysOrg.com) -- There are robots that can fly, and there are robots that can swim, but so far a robot that can both fly and swim does not exist. With the goal to design an aerial/aquatic robotic vehicle, a team of researchers ...
(PhysOrg.com)—Every musical sound comes from a specific way that an instrument is played. With modern technology such as sensors, signal processing, and sometimes machine learning algorithms, researchers can determine the ...
