The study reveals that chemical activity within brain cells exhibits behavior characteristic of self-organized criticality, which may help identify disease processes. Researchers used modeling techniques to simulate brain networks and found a power law distribution of wave sizes and durations, adhering to the signature of self-organize...
The H2Fuel Bus features a unique hybrid power system that uses hydrogen fuel stored in metal hydrides, producing near-zero emissions. The bus will provide valuable experience and raise awareness about hydrogen as an alternative fuel for the future.
A new study shows that nearly half of rural eastern US sites would not meet the new ozone standard, posing health risks to residents. The researchers argue that a regional approach is needed to address rural air pollution, requiring cooperation among states and communities.
Researchers at Georgia Institute of Technology have isolated massive gold-cluster molecules with exceptional quantum properties. The gold cluster materials can be used in single-electronics and exhibit charge-quantization effects, offering a breakthrough for nanoelectronic applications.
Researchers at Georgia Tech are using the university's rooftop solar system to study the performance and reliability of solar power systems. The system has operated close to expectations, producing 162.2 megawatt hours of electricity in its first seven-month period, but factors such as weather conditions have affected energy output.
The role of non-experts in science policymaking is crucial for informed decision making. Non-experts can learn enough to make intelligent decisions about funding and research, suggests expert Dr. Daniel Lee Kleinman. Democratizing science requires new policies to encourage cooperation between experts and non-experts.
Researchers are developing innovative control concepts, such as electrically-actuated piezoelectric structures and tiny jet turbine engines, to build MicroFlyer aircraft. The vehicles must be autonomous, inexpensive, and able to withstand harsh environments.
Research shows that training is essential for overcoming fears about using automatic teller machines (ATMs) among older adults. Studies have found that non-users are willing to try ATMs if shown proper usage, and hands-on training improves success rates. Banks can benefit by making ATMs more personal, interactive, and secure.
The Georgia Tech system automatically identifies defects as fabric comes off the loom, allowing immediate correction of process problems. It provides detailed records of weaving quality to optimize fabric use, and can pinpoint factors causing defects.
The museum has developed an innovative program that allows visitors to reconstruct a fragmented clay pot, draw their own masterpiece, and play a tune on a 1,800-year-old flute using computer kiosks. This 'hands-on' approach makes objects in the museums seem more alive, providing a vast array of information about the artifacts and art o...
The prototype non-Doppler optical sensor registers faint wind movements that anemometers cannot measure, correlating with those of anemometers in test results. It offers a low-cost alternative to complex arrays of traditional sensors and can measure both horizontal and vertical wind speeds.
The latest survey from Georgia Institute of Technology reveals a slowdown in the World Wide Web's expansion, with minor changes in demographics and a significant decrease in new internet users. The study highlights growing concerns over cyberspace privacy, falsification of information, and censorship among web users.
Researchers have developed a prototype electronic house call system that enables patients with chronic diseases to receive regular care from nurses at home. The system, tested in 25 patient homes and a nursing facility, uses videoconferencing and medical devices to monitor vital signs and perform exams.
Scientists have successfully carried out a chemical reaction in the world's smallest test tubes, carbon nanotubes with diameters less than ten nanometers. The research could lead to the production of new types of nanoscale devices, such as metallic wires and electronic emitters.
Researchers at Georgia Institute of Technology developed a novel experimental technique called Thermoiré to track circuit board warpage in real-time. This allows manufacturers to make design changes before production, reducing losses and increasing product reliability.
A computer-based system aims to establish a scientific basis for equitable and sustainable water resources management. The integrated decision support system uses hydrometeorological data to simulate the response of rivers and reservoirs to different climatic inputs, water and power demands, and decision policies.
The Georgia Institute of Technology has established a new Test and Evaluation Research and Education Center (TEREC) to find less expensive ways to test new technologies. The center will provide an international focal point for T&E research and education, and a catalyst for the invention of the future of the discipline.
Research suggests that web users are more likely to be registered voters and participate in local, legislative, and national elections. Additionally, a significant portion of respondents reported being politically active through actions such as writing elected officials and signing petitions.
Researchers at Georgia Institute of Technology and Zoo Atlanta created a virtual reality gorilla exhibit to simulate ape social interaction. The program allows students to become part of a gorilla family, learning realistic behaviors such as submissive postures and interactions with dominant males.
Digital speech analysis tests can quantify signs of intoxication, such as jumpy pitch and energy changes. The test, developed by Georgia Tech researcher Kathleen E. Cummings, analyzes vocal cord movements during speech production.
Researchers at Georgia Institute of Technology have developed a new method to examine and quickly map how nucleic acid ligands bind to and alter DNA at the molecular level. This allows for direct visualization of individual DNA molecules, providing crucial information on drug binding and mode of action.
