Bioelectronic nose sniffs out bacteria in water

Currently, when scientists want to know if bacteria are present in water, they have two main choices. They can take a sample to the lab, where they'll try growing the suspected bacteria in it, and then count the number of resulting colonies to determine the concentration. Or, they can analyze it using expensive lab-based gas chromatography or mass spectrometry equipment. Now, however, researchers from Seoul National University have developed a "bioelectronic nose" that could be used on location, and that is reportedly more sensitive than existing techniques.Read More

Insect-inspired amphibious robot jumps like a water strider

Despite what our science fiction-fueled imaginations love to be entertained with, there is more to the field of modern robotics than colossal combat machines or bionic baristas. Some projects may seem mundane by comparison, yet the results are no less impressive, especially the ones that enlighten through the process. Although it took a few trial and error attempts, scientists have finally created an insect-inspired robot that can jump off of water's surface.Read More

Graphene used to create world's thinnest light bulb

Over 130 years ago, Thomas Edison used carbon as the conducting filament in the very first commercial light-bulb. Now a team of scientists and engineers have used that very same element, in its perfectly crystalline form of graphene, to create what they claim to be the world's thinnest light-bulb. Even though just one atom thick and covering an area almost too small to see unaided, the new device is so bright that the light it produces can easily be seen with the naked eye.Read More

New Samsung app aims to aid social development for children with autism

A new app released by Samsung aims to improve the lives of children suffering from autism by presenting a fun, smartphone or tablet-based developmental aid. Many who have the condition struggle to convey the simplest of emotions or form bonds with others, due to the behavioral development issues that prevent simple interactions such as eye contact. The app, known as Look At Me, is targeted at improving the quality of life for those growing up with autism by aiding in the development of basic social skills. Read More

Cigarette butts transformed into high-performance supercapacitor component

Billions of cigarette butts are discarded around the world each year and, even when disposed of properly, pose a threat to the environment by leaching arsenic, lead and other nasty chemicals into land and waterways. New research shows these butts could be set for a new lease on life, with a team of Korean scientists demonstrating that used cigarette filters could actually double as a highly-effective energy storage material.

Mood Map exhibit turns tweets into art

Mood Map is an art exhibit created by New York-based E/B Office that expresses the mood of the South Korean populace by analyzing their tweets. The data is visualized through six fiber optic lights located on the roof of the Data Curation section of the Museum of Art, at Seoul National University. Read More

Korea shows off salad-tossing robot at Robot World 2012

Researchers from the Korean Institute of Science and Technology's (KIST) Center for Intelligent Robotics (CIR) demonstrated their household service robot, CIROS, at Robot World 2012. CIROS, the third version of the robot since development began in 2005, is intended to help out around the home by performing simple chores. You can watch it prepare a salad by slicing a cucumber and adding dressing in the video after the break.Read More

Laser-based system promises to take the "ouch" out of injections

Nobody likes getting their shots, but whether childhood immunization, annual flu vaccination, or whatever else, we're required to undergo the uncomfortable sensation of needle piercing skin multiple times throughout our lives. However, a new laser-based system promises to take the “ouch” out of injections by delivering shots as painlessly as being struck by a puff of air. Read More

Seoul National University develops inexpensive, super sensitive electronic skin

The quest to give robots touch-sensitive artificial skin and develop medical prostheses with a sense of touch has shown much promise in recent years. The latest promising development comes out of Seoul National University's Multiscale Biomimetic Systems Laboratory where researchers have created a new biomimetic “electronic skin” that is inexpensive, yet sensitive enough to “feel” a drop of water.Read More
