March 5, 2014 – 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.
February 26, 2014 — The annual ritual of visiting a doctor’s office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine. The research, which involved nearly 100 people recruited in the metropolitan Atlanta area, found that test subjects could successfully apply a prototype vaccine patch to themselves.
February 18, 2014 — 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.
February 18, 2014 — 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.
February 18, 2014 — 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.
February 16, 2014 — 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.
February 5, 2014 — 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 22, 2014 — Georgia Tech was one of the first nodes in the National Science Foundation’s (NSF) I-Corps program, which helps faculty members commercialize research discoveries. Twelve teams of researchers have now gone through the program.
January 22, 2014 — Researchers have produced an advanced web-based tool that lets physically separated participants collaborate on model-based systems engineering projects. The program utilizes open-source software components to allow users to visualize a system’s potential expense alongside its performance, reliability and other factors.
January 22, 2014 – During the last North American ice age, large numbers of icebergs calved from the North American ice sheet and plunged into the North Atlantic Ocean. Scientists have thought that these iceberg surges disrupted a key ocean circulation pattern, but a new study found little evidence of a disruption during some of the major iceberg surges.
