OneBusAway App Now Tracks MARTA Trains in Real Time
The mobile app OneBusAway, which tracks public transportation in real time, now includes arrival times for MARTA trains in addition to the MARTA buses and Georgia Tech shuttles already featured in the app.
Single Chip Device to Provide Real-Time 3-D Images from Inside the Heart and Blood Vessels
Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart.
Silicon-Germanium Chip Sets New Speed Record
A research collaboration has demonstrated the world's fastest silicon-based device to date. The investigators operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
Solar-Induced Hybrid Fuel Cell Produces Electricity Directly from Biomass
Researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy. The hybrid fuel cell can use a wide variety of biomass sources, including starch, cellulose, lignin – and even switchgrass, powdered wood, algae and waste from poultry processing.
Researchers Hijack Cancer Migration Mechanism to “Move” Brain Tumors
One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, researchers have learned to hijack this migratory mechanism, turning it against the cancer by using a film of nanofibers thinner than human hair to lure tumor cells away.
Ballistic Transport in Graphene Suggests New Type of Electronic Device
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.
January 13, 2014 — Today’s cyber attacks aren’t just a threat to computer networks. Those with malicious intent can disrupt important infrastructure systems such as utilities and power grids. To counter this threat, the Department of Energy has awarded the Georgia Tech Research Institute (GTRI) $1.7 million to help detect cyber attacks on our nation’s utility companies.
January 13, 2014 – Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports. The study is the first time that molecular chlorine has been measured in the Arctic, and the first time that scientists have documented such high levels of molecular chlorine in the atmosphere.
January 10, 2013 – The Atlantic Pediatric Device Consortium has been awarded $3.5 million over five years by the U.S. Food and Drug Administration to assist scientists, clinicians and entrepreneurs in bringing medical devices for children to the market with greater efficiency.
January 9, 2014 — Competition may have a high cost for at least one species of tropical seaweed. Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals, but at the same time becomes more attractive to herbivorous fish.
December 30, 2013 — A new technique for studying the structure of the childhood RSV virus and its activity in living cells could help researchers unlock the secrets of the virus, including how it enters cells, how it replicates, and perhaps why certain lung cells escape the infection relatively unscathed.
December 23, 2013 – One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 billion years ago, but in a primitive form that later evolved into the RNA and DNA molecules that we have in life today. New research shows one way this chain of events might have started.
December 23, 2013 – Scientists using GPS to study changes in the Earth’s shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica.
December 17, 2013 — The IceCube Neutrino Observatory is helping unravel one of the key scientific mysteries. Using a kilometer cube of solid ice located at the South Pole, the facility is searching for cosmic visitors — neutrino particles from space.
December 13, 2013 — The HomeLab initiative expands Georgia Tech’s product evaluation capabilities in testing health, wellness, and aging-at-home technologies. HomeLab participants test and use these technologies in their homes, assisting manufacturers in design and usability.
December 12, 2013 — Researchers are taking advantage of the unique properties of graphene to design tiny antennas that may open the possibility for networks of nanometer-scale machines. Graphene could generate a type of electronic surface wave that would allow antennas just one micron long and 10 to 100 nanometers wide to do the work of much larger antennas.
