Learning from Ants: Principles of Locomotion in Confined Spaces Could Help Future Robot Teams Work Underground
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
Oxygen-Free: RNA Was Capable of Catalyzing Electron Transfer on Early Earth with Iron’s Help, Study Suggests
A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing electron transfer under conditions similar to those of the early Earth.
Biology of the Brain: Georgia Tech Researchers Seek a Better Understanding of the Brain
Researchers at Georgia Tech are applying their expertise, tools and techniques to understand on a fundamental level how the brain works. Because the human brain is immensely complex, the researchers are pursuing many levels of inquiry – from molecules to cells to circuits to the mystery of the mind itself – and also studying brain disorders and development, along with daily feats of brain activity, such as vision, speech, movement and memory.
Brain Development: Study Shows How Pathway Competition Affects Early Differentiation of Higher Brain Structures
A new study shows how the strength and timing of competing molecular signals during brain development has generated natural and presumably adaptive differences in a brain region known as the telencephalon -- much earlier than scientists had previously believed.
Artificial Transparent Skin: Arrays of Piezoelectric “Taxels” Convert Mechanical Motion to Electronic Controlling Signals for Improved Tactile Imaging
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in signatures and offer new ways for humans to interact with electronic devices.
FlipperBot: Sea Turtles and Flipper-Driven Robot Reveal Principles of Moving on Sand and Other Granular Media
Based on a study of both hatchling sea turtles and "FlipperBot" -- a robot with flippers -- Georgia Tech researchers have learned principles for how both robots and turtles move on granular surfaces such as sand.
February 1, 2007 — A new sensor that measures the motion created by sound waves under water could allow the U.S. Navy to develop compact arrays to detect the presence of enemy submarines. These new arrays would detect quiet underwater targets, while also providing unambiguous directional information.
January 22, 2007 — Georgia Tech researchers have joined with colleagues at six other U.S. institutions to form the Center for Nanotechnology in Society. Headquartered at Arizona State University, the new center has so far received more than $6 million in funding from the National Science Foundation.
January 22, 2007 — Georgia Tech ranks third in the nation for the number of nanotechnology researchers that are “highly cited” in peer-reviewed publications, and in the top ten for the number of first authors publishing in such journals. The statistics are contained in “Connecting the Dots: Creating a Southern Nanotechnology Network,” a study done through the Program in Science, Technology and Innovation Policy.
January 10, 2007 — The Georgia Tech Research Institute (GTRI) has developed a first-of-its-kind system capable of automatically placing raised pavement markers (RPMs) along the lane stripes of highways from a moving vehicle.
In research that could help control contamination from the radioactive element uranium, scientists have discovered that some bacteria found in the soil and subsurface can release phosphate that converts uranium …
Although stormwater runoff may not seem particularly threatening, it ranks among the most common sources of water pollution in the United States. Especially at industrial sites, rain and melting snow …
Large-scale smart weapons such as laser-guided bombs have helped reshape modern warfare. Now, scientists at the Georgia Tech Research Institute (GTRI) are taking an analogous approach with smaller-scale munitions by …
Scientists have used a powerful molecular imaging technique to see inside living cells infected with the most pervasive and potentially fatal childhood respiratory virus known to medicine respiratory syncytial virus …
Years before today’s energy challenges, before Hurricane Katrina, before $70 per barrel oil, several researchers and students at the Georgia Institute of Technology, Imperial College London and the Oak Ridge …
A newly developed family of biodegradable polymers has shown potential for use in intracellular delivery and sustained release of therapeutic drugs to the acidic environments of tumors, inflammatory tissues and …
