When it comes to healing the terrible wounds of war, success may hinge on the first blood clot – the one that begins forming on the battlefield right after an injury. Researchers believe the initial response to injury may control subsequent healing.
A new study provides insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It’s thought that abnormalities in their ability to do so play an important role in a broad range of disorders.
Using underwater video cameras to record fish feeding on South Pacific coral reefs, scientists have found that herbivorous fish can be picky eaters – a trait that could spell trouble for endangered reef systems.
In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms – principally bacteria – in the middle and upper troposphere, that section of the atmosphere approximately four to six miles above the Earth’s surface.
Engineers at the Georgia Tech Research Institute (GTRI) are developing an airborne testing capability for sensors, communications devices and other payloads. Their aerial test bed is known as the GTRI Airborne Unmanned Sensor System (GAUSS).
Researchers have created a biophysical model of the response of a Gram-positive bacterium to the formation of a hole in its cell wall, then used experimental measurements to validate the theory.
Researchers at the Georgia Tech Research Institute (GTRI) are working to counter threats from spear phishing. The attacks use knowledge of computer users to gain their trust to break into corportate networks.
By examining a set of fossil corals that are as much as 7,000 years old, scientists have dramatically expanded the amount of information available on the El Nino-Southern Oscillation, a Pacific Ocean climate cycle that affects climate worldwide.
Researchers are creating graphene p-n junctions by transferring films of the electronic material to substrates that have been patterned by compounds that are either strong electron donors or electron acceptors.
A research team at the Georgia Institute of Technology has received a $2.7 million award from the Defense Advanced Research Projects Agency (DARPA) to develop technology intended to help address the challenges of "big data" – data sets that are both massive and complex.
A new online tool takes the guesswork out of developing individualized catch-up immunization schedules by allowing parents and health care providers to easily create a schedule that ensures missed vaccines and future vaccines are administered according to approved guidelines.
Measles vaccine given with painless and easy-to-administer microneedle patches can immunize against measles at least as well as vaccine given with conventional hypodermic needles, according to research done by the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC).
Researchers at the Georgia Institute of Technology have received a five-year, $1.8 million grant from the National Science Foundation (NSF) to study how complex microbial systems use their genetic diversity to respond to human-induced change.
By fabricating graphene structures atop nanometer-scale “steps” etched into silicon carbide, researchers have for the first time created a substantial electronic bandgap in the material suitable for room-temperature electronics.
Corals under attack by toxic seaweed do what anyone might do when threatened – they call for help. A study reported this week in the journal Science shows that threatened corals send signals to fish “bodyguards” that quickly respond to trim back the harmful seaweed.
Researchers are developing a technique for predicting from a simple blood sample the amount of cathepsins—protein-degrading enzymes known to accelerate certain diseases—a specific person would produce.
Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.
A new study shows that jumping can be more complicated than it might seem. In research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce the amount of energy they use by adopting a unique two-part “stutter jump.”
Understanding blackbody radiation – electromagnetic emissions that play a role in a broad range of physical systems – is an important part of physics instruction at both the high school and college levels. A new iPad app helps explain this to students.
Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found. By altering activity of the macrophage cells that respond to injuries, researchers dramatically increased the rate at which nerve processes re-grew.
