Ingestible origami robot unfolds inside the stomach to remove button batteries
Researchers have developed a tiny origami robot that is swallowed as a capsule, then unfolds in true Transformer style to patch a wound or remove foreign objects, such as button batteries. → Read More
New sensor system enables robots to look inside luggage
A new robot-mountable, sensor system allows authorities to scan abandoned luggage and get an accurate image of its contents. The contact-free detection system can not only potentially help bomb specialists assess danger quickly, but it could also help them obtain vital evidence. → Read More
Wi-Fi signals track and distinguish people through walls
Two years ago, researchers at MIT used Wi-Fi signals to see through walls and track a person's movements. The same team has now come up with a new technology that's not only able to discern a person's silhouette through walls, but can also make out different individuals. → Read More
Finger-shaped sonic tractor beam lifts objects
A new sonic tractor beam created by an international team of researchers uses acoustic holograms shaped like fingers, cages and twisters to move, manipulate and lift a round polystrene bead. → Read More
"Lab in a needle" could streamline medical diagnoses
Scientists have come up with a self-contained lab in a needle-like device which is claimed capable of delivering results to common lab tests instantly. The device could potentially allow doctors to diagnose and treat conditions faster and make it easier to conduct diagnostic tests anywhere. → Read More
Nanoscale wrench is just 1.7 nanometers wide
Scientists have created a nanoscale wrench that has an opening of about 1.7 nanometers, roughly a hundred-thousand-times smaller than the width of human hair. → Read More
Smart light lets you control your environment
Researchers at Dartmouth College have developed a sensing system called LiSense that aims to make the light around us "smart." Not only does it use light to sense people’s movements, but it also allows them to control devices in their environment with simple gestures. → Read More
Sensor detects sound direction and cuts background noise
Researchers at Duke University have developed a prototype sensor that’s not only able to figure out the direction of a particular sound, but can also extract it from background noise. The disk-shaped device is made of plastic and doesn't have any electronic or moving parts. → Read More
Printable solid-state PRISS battery to change the shape of battery technology
By eliminating the need for traditional separator membranes, researchers have created printable solid-state batteries that can be printed in any conceivable shape and can be seamlessly embedded into a variety of surfaces. → Read More
Temperature-controlled hydrogel can walk
Scientists have developed a new hydrogel that stretches and contracts just like an artificial muscle. The team created an L-shaped object made out of the hydrogel and immersed it in a water bath. When the water’s temperature was varied, it slowly "walked" forward. → Read More
Hobbyist creates world's smallest functional circular saw
Lance Abernethy, a maintenance engineer from Auckland, New Zealand has 3D-printed a working circular saw that fits in a briefcase slightly bigger than a thumbnail. It took him less than an hour to print the entire thing. → Read More
Underwater chemical garden powers a light bulb
Researchers at NASA's Jet Propulsion Laboratory have grown underwater chimney-like structures capable of generating enough electricity to power a light bulb. The seafloor equivalents of these chemical gardens might just have contributed the electricity needed for the first organisms to develop. → Read More
Braille smartwatch lets blind read texts
A South Korean startup has created an active Braille smartwatch for the visually impaired that can be read by touch. Aptly named Dot, the wearable relays the time with a set of pins that rise and fall. → Read More
Knocki taps into the internet of things
Knocki is a smart little device that turns solid surfaces like walls, doors or even a coffee table into an interactive remote control. All you have to do is knock. → Read More
Silk-based functional inks put biosensor data on your fingertips
Researchers at Tufts University have now developed silk-based inks containing bacteria-sensing agents that can withstand the rigors of inkjet printing, opening the door much wider for printing biomolecules. → Read More
Review: nabi Big Tab children's tablet
If you're in the market for a big family tablet, the nabi Big Tab more than delivers with your choice of a whopping 20-in or 24-in touchscreen, supported by a child-friendly selection of education... → Read More
Scientists create functioning
Researchers at the University of Cambridge have grown functional mini-lungs using stems cells derived from the skin cells of patients with a debilitating lung disease. The process can also be sc... → Read More
Prosthetic arm takes alternate route to mind control
Researchers from the Medical University of Vienna have developed a technique called bionic reconstruction that allows amputees to control a robotic prosthesis with their mind, when there's no ne... → Read More
SEnS soft exoskeleton enhances sensorimotor functions
Scientists have created an exoskeleton without any electronic motors, heavy batteries and pneumatic actuators called the Sensorimotor Enhancing Suit. The soft upper body vest is made out of flexib... → Read More
Scientist claims that human head transplants could be a reality by 2017
An Italian doctor has outlined a procedure to transplant a human head onto a donor body. The goal is to help people who are paralyzed, or whose bodies are otherwise riddled with degenerative dise... → Read More
