Genome fully mapped for potential biological weapon
The bacterium that causes the severe disease known as rabbit fever, Fancisella tularensis, is a potential biological weapon of devastating force. Now scientists at Ume'å, in collaboration with several international associates, have mapped the entire genome of the bacterium. Researchers at the Swedish Defense Research Agency FOI NBC Defense... view more... (2005-01-12)
New technologies enhance quantum cryptography
A team of Los Alamos National Laboratory scientists, in collaboration with researchers from the National Institute of Standards and Technology in Boulder, Colo., and Albion College, in Albion, Mich., have achieved quantum key distribution (QKD) at telecommunications industry wavelengths in a 50-kilometer (31 mile) optical fiber. view more (2006-02-03)
UCSD study of nuclear receptors could change anti-inflammatory treatments
Several nuclear receptor proteins appear to overlap in their ability to exert anti-inflammatory effects, according to new research by scientists at the University of California, San Diego (UCSD). view more (2005-09-09)
Power of Molecular Imaging Reveals Secrets of the Heart
The extraordinary action of a new cellular therapy came to light as a result of powerful PET and SPECT imaging in a recent study reported in the April issue of the Journal of Nuclear Medicine. view more (2008-04-10)
US satellite protection scheme could affect global communications
A proposed US system to protect satellites from solar storms or high-altitude nuclear detonations could cause side-effects that lead to radio communication blackouts, according to new research. view more (2006-08-15)
Porous ceramic foam - taking the heat out of furnaces
Concerns over the health effects on humans caused by RCF dust lead to a number of studies in the USA. The EU directive in November 1997 and growing legislation from EU member states, including Germany and The Netherlands, has lead to a widespread search for a suitable alternative. Hi-Por, developed by TMS, is proving to be one of the leading... view more... (1999-04-30)
A new approach to engineering for extreme environments
Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found in any of the original compounds, can emerge. view more (2009-06-30)
Model helps explore patterns of urban sprawl and implicaitons for quality of life
Americans like living in cities, and according to statistics in the United Nations World Population Database so do an increasing number of people throughout the world. view more (2007-02-20)
New technique determines that the number of fat cells remains constant in all body types
The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the... view more... (2008-05-12)
Blocking a premature aging syndrome with anticancer drugs
A class of anticancer drugs currently being evaluated in phase 3 clinical trials may also be an effective treatment for Hutchinson-Gilford progeria syndrome (HGPS), a fatal genetic disorder that causes premature aging. view more (2005-08-30)
High calcium level in arteries may signal serious heart attack risk
Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology. view more (2009-07-28)
Los Alamos Scientists See New Mechanism for Superconductivity
Laboratory researchers have posited an explanation for superconductivity that may open the door to the discovery of new, unconventional forms of superconductivity. view more (2008-11-24)
High-performance plasmas may make reliable, efficient fusion power a reality
In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. view more (2009-11-03)
Nuclear Medicine Imaging Allows Immediate Prediction of Advanced Breast Cancer Patients' Response to Hormonal Treatment
Innovative use of somatostatin receptor scintigraphy (SRS), a nuclear medicine imaging technique looking at how the body functions at the molecular level, may provide near immediate selection of breast cancer patients for endocrine therapy and offers a new tool in fighting the disease. view more (2006-01-20)
Chromosomes dance and pair up on the nuclear membrane
Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. view more (2009-11-16)
Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science. view more (2007-10-26)
Chemistry & Industry - 17 June Issue
NEWS Rapid diagnosis while you wait (page 6) A device that can diagnose breast cancer within minutes is being developed by scientists at the University of Dundee, UK. Ear cartilage offers cancer hope (page 7) Replacement testicles that can deliver testosterone for several months have been made from ear cells by scientists in the US. Testicles lost... view more...

U.S. Air Force Technology Helps Scientists Understand Plant Root Function
The McClellan Nuclear Radiation Center (MNRC) in Sacramento, CA was developed by the U.S. Air Force to detect corrosion and defects in aircraft structure using an imaging technique called neutron radiography. This technique is currently helping soil scientists understand the function of plant roots and their uptake of water and nutrients. view more (2008-09-09)
Identifying the "Nuclear" in Nuclear Medicine as High Benefit
Say the word nuclear and it conjures up mistaken ideas about radiation, an invisible, odorless and intangible force that allows doctors to non-invasively see into the body. view more (2006-10-05)
Improved Imaging for Identifying Breast Cancer in Overweight Women
Increasing the ability to identify sentinel nodes—the very first lymph nodes that trap cancer cells draining away from a breast lesion site—has a major impact in the treatment and outcome of breast cancer patients, possibly eliminating the need for unnecessary and painful surgery. view more (2007-02-07)
