Musical Chemical Detector

Researchers at the University of California, Riverside have discovered the chemical detection abilities of an African musical instrument called a mbira. The instrument uses metal times connected to a wooden sounding board which produce a musical tone when plucked. The research has discovered that using a hallow U-shaped tine filled with different liquids produce notes of different frequencies. These differences can be used to detect different liquid samples such as sodium chloride or non-toxic glycerol.

Cool Thing Of The Week: Printed Paper Actuator

Scientists at Carnegie Mellon University's Morphing Matter Lab have created printed paper actuators. By coating paper with conductive thermoplastic, the paper can bend, fold or flatten in response to an electric current. The video demonstrates some interesting uses for this technology, as interface controllers and as a moving publishing medium. (H/T to Mikael for sharing this.)

Entrepreneurial Parasite

A parasite found on cats may make you more entrepreneurial. Researchers at the University of Colorado Boulder found that students infected with Toxoplasma Gondii were 1.4 times more likely to major in business and 1.7 times more likely to to pursue a management and entreprenurial pathway. It is thought that the parasite encourages risk taking behaviour in the host in an attempt to increase the chances of it spreading to other cats.
