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The annual ritual of visiting a doctor’s office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine.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.
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.
December 9, 2013 — Researchers are developing a family of generators that provide power for portable electronic devices and sensors by harnessing the triboelectric effect to capture mechanical energy that would otherwise be wasted.
December 5, 2013 – Wallace H. Coulter would have turned 100 this year. To celebrate the life and scientific legacy of Coulter, his namesake department, the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, is hosting a celebration on Dec. 5-6.
December 4, 2013 – Researchers have shown that the subsurface ocean on Jupiter’s moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.
November 27, 2013 – In a new clinical trial, individuals with paralysis were able to use a tongue-controlled technology to access computers and execute commands for their wheelchairs at speeds that were significantly faster than those recorded in sip-and-puff wheelchairs, but with equal accuracy. This study is the first to show that the wireless and wearable Tongue Drive System outperforms sip-and-puff in controlling wheelchairs. Sip-and-puff is the most popular assistive technology for controlling a wheelchair.
November 26, 2013 – Researcher are attempting to engineer an injectable therapy for the shoulder’s supraspinatus tendon, a rotator cuff tendon that is commonly torn in sports. When the tendon is damaged, the body makes things worse by activating enzymes that further break down the tendon. The scientists hope to develop an injectable compound that would deliver an inhibitor capable of blocking these enzymes, thereby reducing the severity of the injury or even healing the tissue.
November 21, 2013 — Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior, allowing for tailored adhesion to surfaces.
November 18, 2013 – Large amounts of a mineral found in granite, known as feldspar, were found in an ancient Martian volcano. The location of the feldspar also provides an explanation for how granite could have formed on Mars.
November 15, 2013 — Optimization research provided by Georgia Tech helped improve a computer algorithm used to ensure that electricity generation meets the demand in Brazil. The country relies heavily on hydroelectric facilities for its electricity.
