CT scans better than X-rays when detecting abnormalities in patients with H1N1 virus
Computed tomography (CT) scans are better than standard radiography (X-rays) in showing the extent of disease in patients with the H1N1 virus. view more (2009-10-21)
Possible Origin of Cosmic Rays Revealed with Gamma Rays
An international team of astronomers (including the UK) has produced the first ever image of an astronomical object using high energy gamma rays, helping to solve a 100 year old mystery - an origin of cosmic rays. Their research, published in the Journal Nature on November 4th, was carried out using the High Energy Stereoscopic System (H.E.S.S.),... view more... (2004-11-02)
T-ray breakthrough could make detecting disease far easier
A breakthrough in the harnessing of 'T-rays'-electromagnetic terahertz waves-which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced. view more (2006-11-03)
Extremely low-dose MDCT useful for reducing hospital stay for patients with acute abdominal pain
Extremely low-dose MDCT of the abdomen and pelvis is useful in providing needed diagnostic information and reducing hospital stay in patients with acute nonspecific abdominal pain. view more (2007-05-07)
Climate change -- research suggests it is not a swindle
New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. The new evidence shows no reliable connection between the cosmic ray intensity and cloud cover. view more (2008-04-03)
Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. view more (2005-12-14)
XMM-Newton's anniversary view of supernova SN 1987A
Twenty years after the first detection of SN 1987A, the nearest supernova ever detected since the invention of the telescope, XMM-Newton provided a fresh-new view of this object. The source keeps brightening-XMM-Newton confirms. view more (2007-02-26)
Scientists close in on source of X-rays in lightning
University of Florida and Florida Institute of Technology engineering researchers have narrowed the search for the source of X-rays emitted by lightning, a feat that could one day help predict where lightning will strike. view more (2008-07-16)
Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. view more (2008-05-01)
NC State Researchers
Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. view more (2009-04-23)
Scoliosis in children detectable with ordinary light
Lateral curvature of the spine can now be detected without the use of X-rays. Tom Huysmans of K.U.Leuven's Department of Biomechanics and Graphic Design has developed a technique using ordinary light which approaches the precision of radiology. The technique is important for research into scoliosis, a spinal column deformity affecting 2% of... view more... (2004-06-11)
UK study quantifies cancer risk from diagnostic X-rays (pp 340, 345)
The most detailed calculation of its kind to estimate the risk of cancer from exposure to diagnostic X-rays is published in this week's issue of THE LANCET. It suggests that in the UK around 700 of the 124,000 cases of cancer diagnosed annually could be attributable to exposure to diagnostic X-rays. Diagnostic X-rays (used in conventional... view more...

Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters. view more (2006-01-09)
Argonne scientists use lasers to align molecules
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction. view more (2008-05-14)
ESA Looks Further Back In Time
Europe's X- ray Multi Mirror (XMM) space telescope goes on show for the first time on Tuesday 10 February 1998. When it is launched in 1999 into an orbit 70,000 miles above the earth, XMM will search for cosmic x-rays from the intensely hot areas of our galaxy and beyond. Sources of these x-rays include black holes, the nucleii of quasars, vampire... view more... (1998-02-09)
Unusual views of the Sun
For centuries, we have worshipped it and wondered at it, but it`s only now that we are getting a really good look at it. Although you can`t gaze at the Sun with the naked eye, thanks to modern science we can view images of our nearest star that confirm the fiery glory our ancestors could only imagine. Today, our views of the Universe are many... view more... (2002-05-21)
ESA steps towards a great black hole census
Astronomers using ESA's orbiting gamma-ray observatory, Integral, have taken an important step towards estimating how many black holes there are in the Universe. view more (2006-09-08)
VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. view more (2009-11-03)
NRL's Large Area Telescope explores high-energy particles
NASA's Fermi Gamma-ray Space Telescope is making some exciting discoveries about cosmic rays and the Large Area Telescope aboard Fermi is the tool in this investigation. view more (2009-07-29)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. view more (2009-11-03)
