Seahorse's armor gives engineers insight into robotics designs 
The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail's exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other. Researchers are hoping to use a similar structure to create a flexible robotic arm equipped with muscles made out of

Scientists reach the ultimate goal -- controlling chirality in carbon nanotubes
An ultimate goal in the field of carbon nanotube research is to synthesise single-walled carbon nanotubes (SWNTs) with controlled chiralities. Twenty years after the discovery of SWNTs, scientists from Aalto University in Finland, A.M.

Bioengineers create rubber-like material bearing micropatterns for stronger, more elastic hearts
A team of bioengineers at Brigham and Women's Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.

Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Small in size, big on power: New microbatteries the most powerful yet
Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.

Or pipelines that can optimize the rate of flow depending on the volume of fluid coming through them and the environmental conditions outside.
