Clinical Trial Shows Tongue-Controlled Wheelchair Outperforms Popular Wheelchair Navigation System
In a new clinical trial, individuals with paralysis were able to use a tongue-controlled technology to access computers and execute commands for their wheelchairs at speeds that were significantly faster than those recorded in sip-and-puff wheelchairs, but with equal accuracy. This study is the first to show that the wireless and wearable Tongue Drive System outperforms sip-and-puff in controlling wheelchairs.
Scientists Work to Engineer an Injectable Therapy for Rotator Cuff Injuries
Researcher are attempting to engineer an injectable therapy for the shoulder’s supraspinatus tendon, a rotator cuff tendon that is commonly torn in sports. When the tendon is damaged, the body makes things worse by activating enzymes that further break down the tendon. The scientists hope to develop an injectable compound that would deliver an inhibitor capable of blocking these enzymes, thereby reducing the severity of the injury or even healing the tissue.
Sticky Business: Magnetic Pollen Replicas Offer Multimodal Adhesion
Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior, allowing for tailored adhesion to surfaces.
Evidence Found for Granite on Mars
Large amounts of a mineral found in granite, known as feldspar, were found in an ancient Martian volcano. The location of the feldspar also provides an explanation for how granite could have formed on Mars, according to a new study in Nature Geoscience.
Optimization Modeling Helps Control Electricity Supply Continuity in Brazil
Optimization research provided by Georgia Tech helped improve a computer algorithm used to ensure that electricity generation meets the demand in Brazil. The country relies heavily on hydroelectric facilities for its electricity.
Carbon Nanotube Field Electron Emitters Will Get Space Testing
A pair of carbon nanotube arrays will be flying in space by the end of the year to test technology that could provide more efficient micro-propulsion for future generations of spacecraft. The devices will be part of a Cube Satellite (CubeSat) developed by the Air Force Institute of Technology (AFIT).
September 25, 2013 — For owners of delivery truck fleets who may be trying to decide between electric or diesel vehicles, researchers at the Georgia Institute of Technology are offering some advice: comparisons of the energy consumption, greenhouse gas emissions and total cost of ownership for the medium-duty vehicles.
September 19, 2013 — Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the container is made of glass or plastic does make a significant difference.
September 18, 2013 – Microscopic, bottle-like structures with corks that melt at precisely-controlled temperatures could potentially release drugs inside the body or fragrances onto the skin, according to a recently published study.
September 16, 2013 – The National Institutes of Health has awarded Georgia Tech a $2-million research grant to unravel the mechanical forces at play in lymphedema, a poorly understood disease with no cure and little hope for sufferers.
September 11, 2013 – Researchers have discovered the details of how cells repair breaks in both strands of DNA, a potentially devastating kind of DNA damage.
September 6, 2013 — Growing concern about bacterial resistance to existing antibiotics has created strong interest in new approaches for therapeutics able to battle infections. The work of an international team of researchers that recently solved the structure of a key bacterial membrane protein could provide a new target for drug and vaccine therapies able to battle one important class of bacteria.
August 27, 2013 — Georgia Tech researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum in classical physics.
August 22, 2013 — Researchers at the Georgia Institute of Technology are helping the U.S. military make key changes in how aircraft electronic systems, called avionics, are produced. The effort focuses on modifying the design of avionics software, especially the ways in which it interfaces with an aircraft’s hardware and other software.
August 15, 2013 — A Georgia Tech Research Institute (GTRI) team is developing a new generation of advanced radio frequency (RF) jammer technology. The project, known as Angry Kitten, is utilizing commercial electronics, custom hardware development, novel machine-learning software and a unique test bed to evaluate unprecedented levels of adaptability in EW technology.
August 12, 2013 — An experimental health information exchange being tested in the north Georgia city of Rome is helping breast cancer patients access their health information and stay in touch with their doctors. The program, MyJourney Compass, is designed to help patients become more involved their health care decisions.
