Cell phone sensors detect radiation to thwart nuclear terrorism

01-22-2008 · EurekAlert!

Researchers at Purdue University are working with the state of Indiana to develop a system that would use a network of cell phones to detect and track radiation to help prevent terrorist attacks with radiological "dirty bombs" and nuclear weapons.

  1. Delft nano-detector very promising for remote cosmic realms
    01-17-2007 · EurekAlert!
    A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. Merlijn Hajenius developed these sensors for Delft University of Technology's Kavli Institute of Nanoscience, in cooperation with the SRON Netherlands Institute for Space Research. He will receive his PhD degree on 19 January based on this research subject.

  2. Patients need to know that nuclear medicine procedures can trigger radiation alarms
    12-06-2007 · EurekAlert!
    Twenty million nuclear medicine procedures that detect and evaluate heart disease, brain disorders and cancer -- and that use radiopharmaceuticals to treat overactive thyroids and some cancers -- are performed each year. While health care providers in many facilities do provide patients with adequate information about nuclear medicine procedures, there's room for improvement, says a study supported by the Centers of Disease Control and Prevention and the Agency for Healthcare Research and Quality that appears in the December Journal of Nuclear Medicine.

  3. New study evaluates methods to prevent importation of illicit nuclear materials
    10-15-2006 · EurekAlert!
    New study evaluates the need for security measures to prevent importation of a smuggled nuclear device. On Friday, the president signed the SAFE Port Act, which is a good step towards better port security. However, there are two significant limitations to the act. First, it only requires radiation detection, but two-dimensional scans are necessary to detect a weapon if shielding with dense material is used. Also, the act does not require inspections at overseas ports, which are needed to prevent terrorists from detonating a device at a U.S. port because any attempts at detection occur.

  4. New use for stem cells found in war on terrorism
    09-25-2007 · EurekAlert!
    For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries. His most recent discovery, which produces billions of neural cells from a few stem cells, could now aid in national security. In collaboration with the US Naval Research Laboratory, Stice hopes to use his recently developed neural cell kits to detect chemical threats.

  5. New microsensor measures volatile organic compounds in water and air on-site
    09-17-2007 · EurekAlert!
    Researchers at the Georgia Institute of Technology have developed a miniature sensor that uses polymer membranes deposited on a tiny silicon disk to measure pollutants present in aqueous or gaseous environments. An array of these sensors with different surface coatings could be used during field-testing to rapidly detect many different chemicals.

  6. Genomic test could help detect radioactivity exposure from terrorist attacks
    04-02-2007 · EurekAlert!
    In the event of a nuclear or radiological catastrophe -- such as a nuclear accident or a "dirty bomb" -- thousands of people would be exposed to radiation, with no way of quickly determining how much of the deadly substance has seeped inside their bodies. Scientists at Duke University Medical Center have developed a new blood test to rapidly detect levels of radiation exposure so that potentially life-saving treatments could be administered to the people who need them most.

  7. New cancer weapon: nuclear nanocapsules
    08-23-2007 · EurekAlert!
    Rice University chemists have found a way to package some of nature's most powerful radioactive particles inside carbon nanotubes. Alpha-particle radiation is so powerful that cancer cells can be destroyed with just one direct hit from an alpha particle on a cell nucleus. Rice's researchers hope to use their new technology to target tiny tumors and even lone leukemia cells. Their research is available online from the journal Small.

  8. Making sense of sensors
    12-05-2006 · EurekAlert!
    As sensor technology has exploded, fundamental questions about how tointegrate information from many sensors have come to the forefront.In particular, national security measures increasingly depend onsensor technology to detect, for example, radiological or biologicalhazards, hidden mines and munitions, or specific individuals in acrowd. Mathematics, especially the area of topology, provides a wayof addressing such questions.

  9. All roads lead to GUN1
    03-29-2007 · EurekAlert!
    Scientists have identified three different signals that indicate damage to chloroplasts -- the photosynthetic factories of plant cells that give plants their green color -- but little is known about how the signal gets passed on to the nucleus. Scientists at the Salk Institute for Biological Studies made a big step towards explaining how chloroplasts let a cell's nucleus know when things start to go wrong at the periphery so nuclear gene expression can be adjusted accordingly.

  10. Scientists find stem cell switch
    07-26-2007 · EurekAlert!
    Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth. Poor soil structure is a problem in tropical agriculture, where soil becomes compact as it dries out. Professor Liam Dolan, of the John Innes Centre in Norwich, UK and his team determined that the plant hormone ethylene regulates cell division in root stem cells.
