June 11, 2013 — Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures – including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.
June 6, 2013 — A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt climate change events. The 100,000-year climate record adds to data on past climate events.
June 4, 2013 — A new study shows that similar timing patterns are used by many swimming animals to produce undulatory swimming motions. Scientists have created a simple model of these patterns and applied it to understand the connection between electrical signals and body movement in the sandfish, a lizard.
May 28, 2013 — Paper is known for its ability to absorb liquids, making it ideal for products such as paper towels. But by modifying the underlying network of cellulose fibers, etching off surface “fluff” and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids – including water and oil.
May 21, 2013 — Georgia Tech has won a Grand Challenges Explorations award to develop a tissue-engineered model of the human lymphatic system that will support laboratory research into lymphatic filariasis, a parasitic disease known to cause elephantiasis. According to the World Health Organization, the mosquito-borne disease affects more than 120 million persons in tropical areas of the world, and can cause severe disfigurement.
May 21, 2013 — A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in physics, mathematics and materials. The droplets, in a shape known as toroidal, are formed from two dissimilar liquids using a simple rotating stage and an injection needle.
May 20, 2013 — Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
May 20, 2013 — A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding.
May 19, 2013 — A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing electron transfer under conditions similar to those of the early Earth.
Spring/Summer 2012 Research Horizons — Researchers at Georgia Tech are applying their expertise, tools and techniques to understand on a fundamental level how the brain works. Because the human brain is immensely complex, the researchers are pursuing many levels of inquiry – from molecules to cells to circuits to the mystery of the mind itself – and also studying brain disorders and development, along with daily feats of brain activity, such as vision, speech, movement and memory.
