HEADLINES ARCHIVE
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.
Brain Implant Unlocks Speech for ALS Patient
The device allows independent control of a computer typing program to put messages together, based solely on brain activity.
A Twist for Surgical Robotics
A startup called Medrobotics has launched a surgical robotic system that features a design that could make robots a much more common fixture in operating rooms.
All Creatures Great and Small in 3-D
The Beastcam Array, a rapid-capture, field portable tabletop system for making high-resolution, full-color 3D models, is being used to create a digital library of all living organisms.
Nanofiber Coating Prevents Infection in Prosthetics
Each year in the U.S., an estimated 1%-2% of the more than 1 million hip and knee replacement surgeries are followed by infections linked to the formation of biofilms.
Improved Nitrogen Conversion Boosts Soybean Yield
Researchers have designed a method to increase the flow of nitrogen from specialized bacteria in soybean root nodules to the seed-producing organs.
3D Hand Models May Pose Security Risks
A fake 3D hand, essentially a spoof, with someone’s fingerprints could potentially allow a crook to steal a person’s identity.
Clarifying Ultrasound with Color
Identification of finer structural details is easier by adding color to medical ultrasound images.
A Faster Way to Find Pipeline Cracks
The study found that pipeline imperfections could be identified by “tapping” the side of a pipe and then measuring the resulting vibrations against those predicted by computer models.
