Air Filtering Causes Respiratory Symptoms in Machining Shops
A study coordinated by the Finnish Institute of Occupational Health detected deficiencies in the performance of air filtering equipment connected to machine tools used in machining shops.
"Microbubble Oxygenation" Could Save Lives
By pumping microbubbles into the abdomen while removing dangerous carbon dioxide, the process transmits oxygen to the body's core, which is then circulated to the brain and other vital organs.
Improving Multimedia Access for the Disabled
Multimedia content, information technology and communication services are central to our lives. International standards are being developed to help ensure access for people with visual or hearing impairments.
Video: Robot Offers Improved Surgical Precision
The size of a soft drink can, this surgical robot overcomes operating constraints of larger counterparts.
Carbon Quantum Dots Are Produced from Sugarcane Waste
Researchers have found a use for sugarcane pulp as a source of highly fluorescent carbon quantum dots.
Purifying Water for Schools in Developing Countries
The point-of-use slow sand filters are made from readily available five-gallon plastic pails or 55-gallon drums.
Tracking Physical Activity via Wearables Data
Tracking physical activity is important because it is a key component for placing other health data in context.
Light-Seeking Nanorobots Could Have Medical Applications
One difficulty in nanorobot design is to enable these nanostructures to sense and respond to their environment.
Smart Patch Conquers Blood Clots
Microneedles release blood-thinning drug in response to bloodstream levels of a clotting enzyme.
Researchers Generate 3-D Virtual Reality Models of Unborn Babies
Parents may soon be able to watch their unborn babies grow, thanks to technology that transforms MRI and ultrasound data into a 3-D virtual reality model of a fetus.
"Skin-Like" Biomedical Bandage Is Stretchy, Durable
The biomedical device mimics the human skin's elastic properties and sensory capabilities.
Glowing Tumors Help Surgeons Cut Out Brain Cancer
The technique uses near-infrared imaging and the contrasting agent indocyanine green, which fluoresces a bright green under NIR light.
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.
