Japan’s March 11 Tohoku Earthquake, among the strongest ever recorded, is providing scientists with a treasure trove of data on rare magnitude 9 earthquakes -- including new information about how a shock this powerful affects the rock and soil beneath the surface.
With R&D assistance from Georgia Tech and seed funding from the Georgia Research Alliance (GRA), an Atlanta-based company is developing what it hopes will be the next-generation instrument for optimizing eyesight for the hundreds of millions of people who wear glasses or contacts.
Researchers have discovered a way to capture energy transmitted by such sources as radio and television transmitters and cell phone networks. By scavenging this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors or other devices.
Chemists have designed a multiple-compartment gel capsule that can simultaneously deliver hydrophilic and hydrophobic drugs. The microcapsules could be used for the treatment of diseases like cancer, which is often treated using combination chemotherapy.
Georgia Tech researchers have developed innovative software for active reading, an activity that involves highlighting, outlining and taking notes on a document. Taking advantage of touch-screen tablet computers, LiquidText enables active readers to interact with documents using finger motions.
A meta-analysis of bacteria-virus infections reveals a nested structure, with hard-to-infect bacteria infected by generalist viruses and easy-to-infect bacteria attacked by generalist & specialist viruses. These findings could provide insights into strategies for viral-based antimicrobial therapies.
Detroit, Houston, Los Angeles, Phoenix & Hilton Head assessed their supplies of distressed commercial real estate and determined the best way to turn some of it into green space. Known as the Red Fields to Green Fields program, the cities could create 20,000 acres of new parkland & 300,000 new jobs.
Researchers at the Georgia Tech Research Institute (GTRI) have developed a novel iPhone application that may enable persons with Parkinson’s disease and certain other neurological conditions to use the devices to collect data on hand and arm tremors and relay the results to medical personnel.
Using barium oxide nanoparticles, researchers have developed a self-cleaning technique that could allow solid oxide fuel cells to be powered directly by coal gas at operating temperatures as low as 750 degrees Celsius. The technique could provide an alternative for generating electricity from the nation’s vast coal reserves.
Engineers have designed a new microspectrometer architecture using compact doughnut-shaped resonators. An 81-channel instrument achieved 0.6-nanometer resolution over a spectral range of more than 50 nanometers with a footprint less than one square millimeter.
New research shows that systematically controlling the local and global environments during stem cell development helps to effectively direct their differentiation. These findings could help in manufacturing large quantities of stem cells for diagnostic and therapeutic applications in the future.
A new study provides support for Darwin’s hypothesis that the struggle for existence is stronger between more closely related species. While ecologists generally accept the premise, this new study contains the strongest direct experimental evidence yet to support its validity.
By studying the X-rays emitted when superheated gases plunge into massive black holes, astrophysicists at the Georgia Institute of Technology have provided an important test of a long-standing theory that describes the extreme physics occurring when matter spirals into these massive objects.
As part of a project sponsored by the U.S. Army Research Laboratory, researchers are giving autonomous robots the ability to work together to explore and map the interior of buildings. Beyond soldiers, the capability could also help firefighters and other emergency personnel.
Researchers at Georgia Tech built a robot that can penetrate and “swim” through granular material. In this study, they show that by varying the shape of the robot’s head or by tilting it up or down, they can control the robot’s vertical movement in complex environments.
By asking an individual to walk a short distance in front of a radar system while saying the months of the year in reverse order, researchers can determine if that person is impaired and possibly suffering from a concussion. This test could be performed at sporting events or on battlefields.
The meaning of the standard fecal coliform test used to monitor water quality has been called into question by a new study that identified sources of Escherichia coli bacteria that might not indicate an environmental hazard.
A new study reveals that a group of ancient enzymes adapted to substantial changes in ocean temperature and acidity during the last four billion years, providing evidence that life on Early Earth evolved from a much hotter, more acidic environment to the cooler, less acidic global environment today.
Avian embryos could join the list of model organisms used to study a specific type of cell migration called epiboly, a developmental process involving mass movement of cells as a sheet that is linked with medical conditions that include wound healing and cancer.
A "templated growth” technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance. These structures could address the challenge of connecting graphene devices made with conventional architectures.
