Researchers at the Georgia Institute of Technology are exploring an alternate theory for the origin of RNA: they think the RNA bases may have evolved from a pair of molecules distinct from the bases we have today. This theory looks increasingly attractive, as the Georgia Tech group was able to achieve efficient, highly ordered self-assembly in water with small molecules that are similar to the bases of RNA.
Georgia Tech student Rebecca Rolfe analyzed 60 years of Academy Awards acceptance speeches as part of a research project that focused on gratitude. She has outlined the trends and patterns on an interactive website.
As technology continues to transform the business of news dissemination, what role does computation play in the practice of journalism—both today and in the future? Last week, the Georgia Tech College of Computing tried to answer that question during the second “Computation + Journalism Symposium,” held Jan. 31-Feb. 1.
A new study co-authored by the Georgia Institute of Technology indicates that clay minerals, rocks that usually form when water is present for long periods of time, cover a larger portion of Mars than previously thought. In fact, the research team say clays were in some of the rocks studied by Opportunity when it landed at Eagle crater in 2004.
Researchers at Georgia Tech are trying to open the world of tablets to children whose limited mobility makes it difficult for them to perform the common pinch and swipe gestures required to control the devices. They have cave created Access4Kids, a wireless input device that uses a sensor system to translate physical movements into fine-motor gestures to control a tablet.

The results also hint that DNA methylation plays an important role for some disease-related phenotypes in humans, including cancer and autism.
Sierra Nevada Corporation (SNC) is one of three companies that will receive hundreds of millions of dollars from NASA to further develop its commercial human spacecraft system. The company has turned to Georgia Tech for expertise on how to ensure the smoothest possible re-entry for its spacecraft, the Dream Chaser, which is reminiscent of NASA’s space shuttle.
Georgia Tech researchers are focusing on ways to fight cancer by attacking defective genes before they are able to make proteins. Professor John McDonald is studying micro RNAs (miRNAs), a class of small RNAs that interact with messenger RNAs (mRNAs) that have been linked to a number of diseases, including cancer. McDonald’s lab placed two different miRNAs (MiR-7 and MiR-128) into ovarian cancer cells and watched how they affected the gene system.
Computer-generated characters have become so lifelike in appearance and movement that the line separating reality is almost imperceptible at times. But while bipeds and quadrupeds have reigned supreme in CG animation, attempts to create and control their skeleton-free cousins using similar techniques has proved time-consuming and laborious. Georgia Tech researchers have found a possible solution to this challenge by developing a way to simulate and control movement of computer-generated characters without a skeletal structure.
Muscle size, genetics and training are among the countless factors that separate Olympic sprinters from the average person. On a fundamental level, however, the mechanics of running are the same for all humans. In fact, they’re basically identical for animals too.
Scientists widely believe that volcanic particle size is determined by the initial fragmentation process, when bubbly magma deep in the volcano changes into gas-particle flows. But new Georgia Tech research indicates a more dynamic process where the amount and size of volcanic ash actually depend on what happens afterward, as the particles race toward the surface.
Georgia Tech has created a wireless, musical glove that may improve sensation and motor skills for people with paralyzing spinal cord injury.
Using a process called paleo-experimental evolution, Georgia Tech researchers have resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli(E. coli) bacteria. This bacterium has now been growing for more than 1,000 generations, giving the scientists a front row seat to observe evolution in action.
Wedding DJs everywhere should be worried about job security now that a new robot is on the scene.
