Dynamic graph analytics tackle social media and other big data

November 6, 2014 -- Researchers at the Georgia Tech Research Institute (GTRI) are bringing graph analytics to bear on a range of data-related challenges, developing advanced technology that can help investigate social networks, surveillance intelligence, computer-network functionality, industrial control systems, and more.

Study Shows Cellular RNA Can Template DNA Repair in Yeast

September 3, 2014 -- Scientists have shown that RNA produced within cells of a common budding yeast can serve as a template for repairing the most devastating DNA damage – a break in both strands of a DNA helix.

BlackForest Aggregates Threat Information to Warn of Possible Cyber Attacks

July 23, 2014 -- Researchers have developed a new open source intelligence gathering system designed to create a picture of developing threats. BlackForest complements other GTRI systems designed to help corporations, government agencies and nonprofit organizations battle increasingly-sophisticated threats to their networks.

Gene Expression Signature Identifies Patients at Higher Risk for Cardiovascular Death

May 29, 2014 -- A study of 338 patients with coronary artery disease has identified a gene expression profile associated with an elevated risk of cardiovascular death. Used with other indicators such as biochemical markers and family history, the profile – based on a simple blood test – may help identify patients who could benefit from personalized treatment and counseling designed to address risk factors.

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.

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.

New Patent Mapping System Helps Find Innovation Pathways

January 14, 2014 -- A new patent mapping system that considers how patents cite one another may help researchers better understand the relationships between technologies – and how they may come together to spur disruptive new areas of innovation.
