MINT Program Helps Pinpoint Threats Contained in Intelligence Data

May 21, 2014 -- Every day U.S. military and security units receive vast amounts of data collected by intelligence, surveillance and reconnaissance (ISR) sensors. To aid this effort, researchers are helping to improve the capabilities of the nation’s Multi-Disciplinary Intelligence (Multi-INT) system, which monitors this incoming data.

Making Money from Lignin: Roadmap Shows How to Improve Lignocellulosic Biofuel Biorefining

May 15, 2014 - A new review article in the journal Science points the way toward a future where lignin is transformed from a waste product into valuable materials such as low-cost carbon fiber for cars or bio-based plastics. Using lignin in this way would create new markets for the forest products industry and make ethanol-to-fuel conversion more cost-effective.

Ovarian Cancer Cells Are More Aggressive On Soft Tissues

May 8, 2014 - When ovarian cancer spreads from the ovaries it almost always does so to a layer of fatty tissue that lines the gut. A new study has found that ovarian cancer cells are more aggressive on these soft tissues due to the mechanical properties of this environment. The finding is contrary to what is seen with other malignant cancer cells that seem to prefer stiffer tissues.

Evolution in Species May Reverse Predator-Prey Population Cycles

May 5, 2014 -- According to a study published in the journal Proceedings of the National Academy of Sciences, co-evolutionary changes in species may reverse traditional predator-prey population cycles, creating the appearance that prey are eating the predators.

Graphene is Only as Strong as its Weakest Link: Experiments Determine Real-world Limits of Two-dimensional Carbon

April 29, 2014 -- Research laboratories at Rice University and Georgia Tech have tested the fracture toughness of graphene for the first time by making and measuring "pre-cracks" under stress.

Researchers Convert Basic Discoveries in Materials Science and Engineering to Real-World Applications

Research Horizons Winter-Spring 2014 -- Materials research is a major priority at Georgia Tech that involves some 200 faculty members. Major research areas include materials for electronics, infrastructure, energy, environment, transportation, biotechnology, aerospace and defense.

Cosmic Slurp: Researchers Predict Signs of Black Holes Swallowing Stars

April 17, 2014 -- Using a mix of theoretical and computer-based approaches, researchers are trying to predict the dynamics of events such as black holes devouring stars, a scenario also known as a "tidal disruption."

Neuromorphic Computing “Roadmap” Envisions Analog Path to Simulating Human Brain

April 16, 2014 -- Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer that mimics the brain's operation.

Fish From Acidic Ocean Waters Less Able to Smell Predators

April 14, 2014 - Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.

Researchers Determine How Mechanical Forces Affect T-Cell Recognition and Signalling

April 10, 2014 -- Researchers have developed a new understanding of the T-cell recognition process by describing how T-cell receptors use mechanical contact – the forces involved in their binding to antigens – to make decisions about whether or not the cells they encounter are threats.
