Moving Iron in Antarctica

June 12, 2013 — Georgia Tech research indicates that diatoms stuff more iron into their silica shells than they actually need. As a result, there’s not enough iron to go around, and the added iron may stimulate less productivity than expected.

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. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

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, and may help scientists assess models designed to predict how the Earth’s climate will respond in the future.

Model Finds Common Muscle Control Patterns Governing the Motion of Swimming Animals

June 4, 2013 — What do swimmers like trout, eels and sandfish lizards have in common? According to a new study, the similar timing patterns that these animals use to contract their muscles and produce undulatory swimming motions can be explained using a simple model. Scientists have now applied the new model to understand the connection between electrical signals and body movement in the sandfish.

A Text Message A Day Keeps the Asthma Attack Away

April 30, 2013 — Simply sending children with asthma a text message each day asking about their symptoms and providing knowledge about their condition can lead to improved health outcomes.

IRI Intros: 5 Questions with Tim Lieuwen

April 29, 2013 — You’ve probably heard that Georgia Tech has a number of Interdisciplinary Research Institutes (IRIs) – but do you know much about them? This article is part of a series of Q&As to introduce the Tech community to the eight IRIs and their faculty leaders. In this installment, Executive Director Tim Lieuwen answers questions about the Georgia Tech Strategic Energy Institute.

How Would You Like Your Assistant - Human or Robotic?

April 29, 2013 — Based on a Georgia Institute of Technology study, it appears that the healthcare providers will welcome robots into the workplace. y may be welcomed with open arms depending on the tasks at hand.

VIDEO - Robots Reach through a Cluttered World

Robots Able to Reach through Clutter with Whole-Arm Tactile Sensing

April 29, 2013 — Robots are now able to intelligently maneuver within clutter, gently making contact with objects while accomplishing a task, thanks to technology developed by Dr. Charlie Kemp and the Healthcare Robotics Lab.

Pathway Competition Affects Early Differentiation of Higher Brain Structures

April 26, 2013 — A new study in fish shows how the strength and timing of competing molecular signals during brain development has generated natural and presumably adaptive differences in a brain region known as the telencephalon -- much earlier than scientists had previously believed.

New Study Offers Insight on Pandemic Flu

April 25, 2013 — A recent study published in PLoS ONE, a peer-reviewed scientific journal, provides new information for public health officials on mitigating the spread of infection from emerging flu viruses

Piezoelectric “Taxels” Convert Motion to Electronic Signals for Tactile Imaging

April 25, 2013 — Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Sea Turtles and FlipperBot Show How to Walk on Granular Surfaces like Sand

April 23, 2013 — Based on a study of both hatchling sea turtles and "FlipperBot" -- a robot with flippers -- researchers have learned principles for how both robots and turtles move on granular surfaces such as sand.

What Drives Activity on Pinterest?

April 23, 2013 — Researchers at Georgia Tech and the University of Minnesota have released a new study that uses statistical data to help understand the motivations behind Pinterest activity, the roles gender plays among users and the factors that distinguish Pinterest from other popular social networking sites.

Researchers Develop Sensor System to Assess the Effects of Explosions on Soldiers

April 22, 2013 — To study the effects of improvised explosive devices on soldiers and help provide continuing treatment, researchers have developed a sensor system that measures the physical environment of an explosion and collects data that can correlate what the soldier experienced with long-term outcomes.
