Mammograms could potentially save more lives with technology developed by researchers at Oak Ridge National Laboratory and the University of Chicago. The proposed system would allow doctors to quickly identify trends specific to an individual patient and also correspond to images and text to a database of cancer and precancerous conditions known. ‘Our goal is to develop a decision-making and support that helps doctors and patients,’ said Robert Patton of Computational Science and Engineering Division at ORNL. ‘There is a wealth of existing information that doctors can use, but with limited time and resources, it is virtually impossible.’ So far, the researchers studied 60,000 12,000 mammography patientsIntrusion detection systems used by governments, businesses and all those who want to prevent cyber attacks may soon be upgraded with a highly sophisticated tool developed at the Oak Ridge National Laboratory. ‘Orca is actually sitting on top of off-the-shelf systems, intrusion detection and its correlation engine processes information and learns that information events occur,’ said Justin Beaver, who heads the ‘development team . The main features include the ability to interact with the operator of the Orca, its flexibility and configurability. Cybersecurity is becoming a growing concern as the home of a Congressional Research Service recently pegged the cost of cyber attacks on businesses $ 226 billion a year. Lockheed Martin has supported this project and has incorporated this feature in his defense and self-healing networks, an experimental system for cyber defense.
Using a combination of experimental techniques and calculation, a team of researchers at Oak Ridge National Laboratory and the University of Tennessee has discovered a new type of receptors in bacteria that changes the direction of the concentration of oxygen and other redox parameters. Their work, which was published online in the Proceedings of the National Academy of Sciences (PNAS), could help scientists better understand how the revelation of ‘environment is linked to cellular metabolism and to predict the behavior of hundreds of bacterial species that have yet to be studied experimentally.
An update of the fan that will save complex calculations Oak Ridge National Laboratory $ 150 000 annually in energy costs is just the latest step from the laboratory to reduce its carbon footprint of IT. The update is just the latest in a series of measures by the laboratory to reduce the energy footprint, while retaining two of the fastest computers in the world and solve some of the most urgent problems of science, new materials, alternative energy for the role proteins in disease. The CSB has been among the leaders of the First in Energy and Environmental Design (LEED) certified computer facilities in the country and one of the best energy saving assessments of use of any scale data centers. In addition, a new cooling system, called the Cray supercomputer ECOphlex laboratory allows the laboratory to reduce the amount of ice water to cool the Jaguar, the fastest supercomputer in the world. Considering the fact that thousands of gallons of water per minute are required to maintain cool Jaguar, a reduction in the volume of chilled water required means a lower proportion of energy used for cooling. While most centers use 0.8 watts of cooling for every watt of energy used for data processing, ORNL has a much better ratio 0.3 to 1, the lowest of all measured data centers.
