Scientists Detect Cosmic 'Dark Flow' Across Billions of Light Years
Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of matter that lies beyond the observable universe.   view more (2008-09-24)

NASA's Swift Catches Farthest Ever Gamma-Ray Burst
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away.   view more (2008-09-23)

Radioactivity: Discover the lowest amounts with new methods
Detecting ever lower amounts of ionising radiation with ever better methods - sci-entists have had this goal since the start of the nuclear age.   view more (2008-09-17)

Improving our ability to peek inside molecules
It's not easy to see a single molecule inside a living cell. Nevertheless, researchers at Lawrence Livermore National Laboratory are helping to develop a new technique that will enable them to create detailed high-resolution images, giving scientists an unprecedented look at the atomic structure of... view more (2008-09-17)

'Naked-eye' gamma-ray burst was aimed squarely at Earth
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth.   view more (2008-09-12)

The Double Firing Burst
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth.   view more (2008-09-11)

Brightest stellar explosion heralds new type of long-distance astronomy
A flash of light that blinded even small telescopes six months ago was the brightest astronomical explosion ever observed - visible to the naked eye despite originating halfway across the universe.   view more (2008-09-11)

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... view more (2008-09-09)

LHC switch-on fears are completely unfounded
A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday next week, poses no threat to mankind. Nature's own cosmic rays regularly produce more powerful particle collisions than... view more (2008-09-08)

Tiny 3-D ultrasound probe guides catheter procedures
An ultrasound probe small enough to ride along at the tip of a catheter can provide physicians with clearer real-time images of soft tissue without the risks associated with conventional x-ray catheter guidance.   view more (2008-08-29)

Study says eyes evolved for X-Ray vision
The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in 3-D. Now, a new study from a scientist at Rensselaer Polytechnic Institute has uncovered a truly eye-opening advantage to binocular vision: our ability to see through things.   view more (2008-08-29)

GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays.   view more (2008-08-27)

Discovery opens door for drugs to fight bird flu, other influenza epidemics
Researchers at Rutgers University and The University of Texas at Austin have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza.   view more (2008-08-26)

Seeing through tooth decay
Dental caries afflict at least 90% of the world's population at some time in their lives. Detecting the first signs of this disease, which can be lethal in extreme cases, just got easier thanks to work by researchers in India discussed in the latest issue of the International Journal of Biomedical... view more (2008-08-25)

Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple... view more (2008-08-20)

Pesticide build-up could lead to poor honey bee health
Honey bees industriously bring pollen and nectar to the hive, but along with the bounty comes a wide variety of pesticides, according to Penn State researchers.   view more (2008-08-19)

X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks?   view more (2008-08-13)

Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.   view more (2008-08-07)

Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor.   view more (2008-08-05)

The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.   view more (2008-07-25)

A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory.   view more (2008-07-17)

Possible link found between x-rays and prostate cancer
Researchers at The University of Nottingham have shown an association between certain past diagnostic radiation procedures and an increased risk of young-onset prostate cancer - a rare form of prostate cancer which affects about 10 per cent of all men diagnosed with the disease.   view more (2008-07-16)

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)

Schizophrenia linked to dysfunction in molecular brain pathway activated by marijuana
Alterations in a molecular brain pathway activated by marijuana may contribute to the cognitive symptoms of schizophrenia, according to a report in the July issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-07-08)

Statins have unexpected effect on pool of powerful brain cells
Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.   view more (2008-07-07)
