Los Alamos Observatory Fingers Cosmic Ray 'Hot Spots'
A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays. The research calls into question nearly a century of understanding about galactic magnetic fields near our solar system.

VLT Observations Confirm that the Universe Was Hotter in the Past
UVES Measures the Cosmic Temperature 12 Billion Years Ago Summary A fundamental prediction of the Big Bang theory has finally been verified. For the first time, an actual measurement has been made of the temperature of the cosmic microwave background radiation, at a time when the Universe was only about 2.5 billion years old. This fundamental and... view more... (2000-12-19)
Cosmologists 'see' the cosmic dawn
The images, produced by scientists at Durham University's Institute for Computational Cosmology, show the "Cosmic Dawn" - the formation of the first big galaxies in the Universe. view more (2009-02-11)
Radiologists find a technique to significantly reduce patient radiation dose during CT angiography
Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease. view more (2009-09-21)
Astronomers discover new radio signal using large balloon
A team of NASA-funded scientists, including two from UC Santa Barbara, have discovered cosmic radio noise that they find completely unexpected and exciting. view more (2009-01-08)
Rare pancreatic cancer patients may live longer when treated with radiation therapy
Radiation therapy is effective in achieving local control and palliation in patients with pancreatic neuroendocrine tumors (PNTs), despite such tumors being commonly considered resistant to radiation therapy. view more (2009-11-23)
Where are the supermassive black holes hiding?
European and American scientists, on a quest to find super-massive black holes hiding in nearby galaxies, have found surprisingly few. Either the black holes are better hidden than scientists realised or they are lurking only in the more distant universe. view more (2006-07-27)
More 'Star Trek' than 'Snuggie': Student design to protect lunar outpost from dangerous radiation
Alien creatures are the least of NASA's worries when it comes to moon travel. There are several potential threats to future missions - with space radiation at the top of the list. view more (2009-05-12)
New study focuses on radiation-associated cancer risks
Concerns about the risk of radiation-induced cancer are growing with the increasing number of cancer patients surviving long term. view more (2007-01-12)
Space radiation threats to astronauts addressed in federal research study
A better understanding of solar storms and how best to protect astronauts from space radiation is needed as NASA pushes toward manned missions to the moon and Mars in the coming decades, according to a new National Research Council report. view more (2006-10-26)
Optimal adjuvant radiation therapy associated with improved survival, meta-analysis shows
A new analysis of adjuvant radiation therapy in women with breast cancer following mastectomy is associated with better survival as measured at 10 years when appropriate doses and fields of radiation are used. view more (2006-01-04)
Fossil galaxy reveals clues to early universe
A tiny galaxy has given astronomers a glimpse of a time when the first bright objects in the universe formed, ending the dark ages that followed the birth of the universe. view more (2006-01-13)
NASA's Fermi Explores High-energy
Since its launch last June, NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars, probed gamma-ray bursts and watched flaring jets in galaxies billions of light-years away. view more (2009-05-05)
Radiation after surgery doubles survival time for some lung cancer patients
Patients with lung cancer that has spread to mediastinal lymph nodes - located between the chest, breastbone and spine - who receive radiation after surgery and chemotherapy live twice as long as patients who do not receive radiation after surgery. view more (2006-11-07)
CT Scans Increase Cancer Risk Estimates in Multiply-Imaged Emergency Department Patients
Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam. view more (2009-05-06)
Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail. view more (2007-04-25)
Superstrings could add gravitational cacophony to universe's chorus
Albert Einstein theorized long ago that moving matter would warp the fabric of four-dimensional space-time, sending out ripples of gravity called gravitational waves. No one has observed such a phenomenon so far, but University of Washington researchers believe it is possible to detect such waves coming from strange wispy structures called cosmic... view more...

New radiation protection technique results in reduced physician exposure
A new radiation protection technique can significantly reduce physician radiation exposure during coronary angiography, according to a researcher at the University of Maryland Medical Center in Baltimore, MD. view more (2006-05-03)
Men with prostate cancer avoid radiation due to misconceptions
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery. view more (2006-11-06)
Cold Dust At The Heart Of TheUniverse
The Universe contains vast quantities of very cold dust and gas; from the relatively dense regions where young stars are born to the most distant galaxies, still in the process of forming after the Big Bang. The new SCUBA instrument, conceived, designed and built at the Royal Observatory, Edinburgh and installed on the James Clerk Maxwell... view more... (1996-06-28)
