Bringing Silicon to Life
A team of scientists at Caltech has "bred" a bacterial protein with the ability to make man-made bonds between silicon and carbon.
Wildfire Emissions Analyzed for Health, Climate Effects
A special chamber allows controlled combustion of fuels under flaming and smoldering conditions, after which the emitted smoke particles are aged photochemically in a flow tube reactor.
Spinach Plants Engineered to Detect Explosives
This is one of the first demonstrations of the engineering of electronic systems into plants.
Smartphone "Laboratory" Detects Cancer Biomarker
Although smartphone spectrometers exist, they monitor or measure only a single sample at a time, making them inefficient for many real-world applications.
Wearable Terahertz Scanner Made with Carbon Nanotubes
Applications in industrial as well as medical non-invasive imaging are envisioned for the flexible, portable device.
Smart Cities for the Golden Years
Smart City technologies have the potential to enable the disabled and elderly to remain independent for longer, and live healthy, mobile lives. Standards are being developed to help meet these goals.
Hand-Held Breathalyzer for Diagnosing Diabetes?
Many studies examining the hallmarks of diabetes in exhaled breath have shown that elevated levels of acetone are strongly linked to the disease.
Patch for Mobile Health Monitoring
Multiple sensing functions are combined with a chip optimized for low power consumption.
Soft Sensor Monitors Heart, Recognizes Speech
With a wearable vibration sensor, human body acoustics can be used for cardiovascular monitoring.
Biodegradable, Drug-loaded Fiber Is Introduced
New biodegradable fiber can be loaded to deliver drugs, vaccines, and even cells or live viruses to the body exactly where needed.
Portable Water Purification with Foil-Based LEDs
Nanowire-enhanced LEDs shine in the high-energy “deep” end of the UV spectrum.
Gold Nanowires Allow Operations at Cellular Level
Conventional surgical tools, including electrodes that are implanted in people's tissue, are unfavorably large on the cellular level.
Vocal Biomarkers for Coronary Artery Disease
Certain vocal sound characteristics point to the existence of the disease.
Sweet Approach to Water Disinfection?
Paper strips infused with sugar and a natural antimicrobial agent treat small volumes of water.
Could Bacteria Create Building Foundations?
Researchers are modifying E. coli bacteria to create a "gene circuit" that would enable the bacteria to respond to their environment by producing biocements.
Complete Sanitation of Robotic Surgical Instruments Impossible
Cleanings were 97.6% effective for robotic instruments and 99.1% effective for ordinary instruments.
"Bionic" Chip Will Aid Study of Neurological Diseases
The chip mimics the natural biological contact between brain cells, essentially tricking them into believing they are connecting with other brain cells.
Biomimetic Fin Helps Maimed Sea Turtle
The new flipper design could allow injured turtles to be rehabilitated and live a more normal life.
Detecting Exposure to Nuclear Materials
The goal of the research was to determine if hair, fingernail clippings and toenail clippings could be used to better detect uranium exposure.
Wireless Implant Helps Paralyzed Primates Walk
A wireless brain-control system recreates signals recorded from the brain and stimulates electrodes in the leg.
