Researchers suggest magicians' mirror tricks could be used as large scale cloaking devices (w/ video)
Hair sensor uncovers hidden signals
An "artificial cricket hair" used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals – they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility ...
What's in a name?
Names can provide a clue to a person's background, and with certain names come certain preconceptions. But could a parent's choice of name for their child be influenced by evolution? Scientists from Queen Mary, University ...
New speaker system for cars creates separate 'audio zones' for front and rear

Terahertz technology: Seeing more with less
Terahertz technology is an emerging field that promises to improve a host of useful applications, ranging from passenger scanning at airports to huge digital data transfers. Terahertz radiation sits between ...
Do-it-yourself invisibility with 3-D printing
Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.
Researchers develop 'smart' paper and antennaless RFID tags
Research teams at North Dakota State University, Fargo, have developed a method to embed radio frequency identification (RFID) tags in paper, which could help combat document counterfeiting, and have developed ...
Printable 'bionic' ear melds electronics and biology
Scientists at Princeton University used off-the-shelf printing tools to create a functional ear that can "hear" radio frequencies far beyond the range of normal human capability.
