Tiny Chemistry: Star-shaped Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

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.

Cave Data: Borneo Stalagmites Provide New View of Abrupt Climate Events Over 100,000 Years

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.

Studying Swimmers: New Model Finds Common Muscle Control Patterns Governing the Motion of Swimming Animals

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.

Water- and Oil-Proof: Advanced Paper Could be Foundation for Inexpensive Biomedical and Diagnostic Devices

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.

Grand Challenges: Gates Foundation Grant Supports Tissue Engineered Model of Lymphatic System

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.

Liquid Doughnuts: Soft Matter Offers New Approaches to Studying How Ordered Materials Arrange Themselves Inside Non-spherical Spaces

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.

Learning from Ants: Principles of Locomotion in Confined Spaces Could Help Future Robot Teams Work Underground

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.

Drug Targeting: Protein Study Suggests Drug Side Effects are Inevitable – and that Basic Physics Enabled Early Biochemistry

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.

Oxygen-Free: RNA Was Capable of Catalyzing Electron Transfer on Early Earth with Iron’s Help, Study Suggests

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.

Biology of the Brain: Georgia Tech Researchers Seek a Better Understanding of the Brain

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.
