With the health of honeybee colonies wavering and researchers trying to find technological ways to pollinate plants, a new Georgia Tech study has looked at how the insects do their job and clean pollen from their bodies.
Vast seas covered much of the early Earth, and scientists have long debated what kept those seas from freezing. A popular theory is that potent gases such as methane created a thicker greenhouse atmosphere than is required to keep water liquid today.
Using tiny snippets of DNA as “barcodes,” researchers have developed a new technique for rapidly screening nanoparticles for their ability to selectively deliver therapeutic genes to specific organs of the body.
Researchers at Georgia Institute of Technology and the Piedmont Heart Institute are using standard medical imaging and new 3-D printing technologies to create patient-specific heart valve models that mimic the physiological qualities of the real valves.
