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.
Self-Administration of Flu Vaccine with a Patch May be Feasible, Study Suggests
The annual ritual of visiting a doctor’s office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine.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.
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.
