  • Model Computes Genetic Test, Family History Predictive Value

    Researchers at the genetic testing company 23andMe in Mountain View, California devised a mathematical model that shows the relative value of personal family history and genetic tests in assessing risk of contracting various conditions and disorders. The results of their research appear in the journal PLOS Genetics. The study aimed to compare family health histories…

  • National Lab Builds Android Network for Security Simulations

    Researchers at Sandia National Laboratory in Livermore, California created a virtual network of some 300,000 mobile devices using the Android operation system to study issues related to large-scale network security. Sandia Lab expects to soon demonstrate the MegaDroid network, as its called, for potential industry and government collaborators. “Smartphones are now ubiquitous and used as…

  • Visual Simulation Method Developed for Liquid Movements

    Computer scientists at University of Copenhagen and two other institutions in Denmark created a new and more precise method for visualizing the movement of liquids. The team led by Copenhagen computer graphics professor Kenny Erleben (pictured right), with colleagues from Technical University of Denmark and Alexandra Institute in Aarhus, Denmark presented their findings at this…

  • Wearable Sensor System Creates Real-Time Environment Maps

    Computer scientists at Massachusetts Institute of Technology developed a portable array of sensors that can create a digital map of a person’s environment, such as a building, while the person wearing the system walks around that environment. Maurice Fallon (pictured right), a research scientist in MIT’s Computer Science and Artificial Intelligence Laboratory, and colleagues, will…

  • Purdue, Adobe Create Process to Strengthen 3-D Print Objects

    Computer scientists at Purdue University in Indiana and computer software company Adobe Systems devised an automated process to add more robustness to objects created through three-dimensional printing. The researchers discussed their methods in a presentation last month at the SIGGRAPH 2012 conference in Los Angeles. 3-D printers create shapes by adding various materials layer-by-layer, including…

  • Simulations Helping Design Cardiac Pump Improvements

    Engineers at University of California in San Diego are devising computer simulations of a widely used pediatric heart pump to reduce the risk of blood clots to patients using the device. Mechanical/aerospace engineer Alison Marsden (pictured left) and structural engineer Yuri Bazilevs are leading teams of colleagues from their respective disciplines to better understand a…

  • Leukemia Genetic Signature, Drug Candidates Identified

    Researchers at University of Rochester in New York identified a set of genes behind the early growth of leukemia stem cells, and used those cells to highlight potential existing drugs with the chemistry to target those cells. The team led by senior investigator and Rochester medical school professor Craig Jordan — with colleagues from Weill…

  • National Lab, Software Company Form Text Analysis Subsidiary

    Oak Ridge National Lab in Tennessee formed a subsidiary with Professional Project Services (Pro2Serve), an engineering company in Oak Ridge, to provide text analysis services using software developed at the lab. The software, known as Piranha, performs high-volume document analysis for military and security users. Financial terms of the deal were not disclosed. Piranha analyzes…

  • Process Developed for Stronger Alloys at High Temperatures

    Materials scientists at Massachusetts Institute of Technology devised a process for growing and merging nanoscale metallic crystals to create alloys that can withstand the stress of high temperatures. MIT graduate students Tongjai Chookajorn and Heather Murdoch (pictured left), with faculty advisor Christopher Schuh, discuss their methods in this week’s issue of the journal Science; paid…

  • University to Research 3-D Self-Assembly Processes

    Engineers at North Carolina State University in Raleigh received a grant to develop materials that fold themselves into three-dimensional objects when exposed to light. National Science Foundation awarded the four-year, $1.76 million grant to Jan Genzer (pictured right), a chemical engineering professor at NC State. Genzer says he is assembling a team of “designers, engineers,…
