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)

XMM-Newton reveals a magnetic surprise
ESA's X-ray observatory XMM-Newton has revealed evidence for a magnetic field in space where astronomers never expected to find one. The magnetic field surrounds a young star called AB Aurigae and provides a possible solution to a twenty-year-old puzzle.   view more (2007-02-23)

Integral expands our view of the gamma-ray sky
Integral's latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. With over seventy percent of the sky now observed by Integral, astronomers have been able to construct the largest catalogue yet of individual gamma-ray-emitting celestial... view more (2007-02-21)

Sophisticated ESA space weather tool under development
If a satellite encounters high-energy particles or other 'space weather' phenomena before ground controllers can take action, on-board electronics could be disrupted, scientific instruments damaged and, in very rare and extreme cases, spacecraft may even be lost.   view more (2007-02-05)

Water theory is watertight, researchers say
There may be tiny bubbles in the wine, but not at the interface between water and a waxy coating on glass, a new study shows.   view more (2007-01-18)

Chemical switch triggers critical cell activities
The freeze-frame image of a molecular relay race, in which one enzyme passes off a protein like a baton to another enzyme, has solved a key mystery to how cells control some vital functions.   view more (2007-01-17)

Chandra discovers light echo from the Milky Way's Black Hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center.   view more (2007-01-11)

A star's death comes to light
Using NASA's Chandra X-ray Observatory, scientists have created a stunning new image of one of the youngest supernova remnants in the galaxy. This new view of the debris of an exploded star helps astronomers solve a long-standing mystery, with implications for understanding how a star's life can... view more (2007-01-10)

New Evidence Links Stellar Remains to Oldest Recorded Supernova
The new study shows that the supernova remnant RCW 86 is much younger than previously thought. As such, the formation of the remnant appears to coincide with a supernova observed by Chinese astronomers in 185 A.D. The study used data from NASA's Chandra X-ray Observatory and the European Space... view more (2007-01-05)

Dentists could detect osteoporosis, automatically
Researchers in the School of Dentistry at The University of Manchester have created a unique way of identifying osteoporosis sufferers from ordinary dental x-rays.   view more (2007-01-04)

Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought.   view more (2006-12-21)

Astronomers discover new kind of black-hole explosion
Scientists have discovered what appears to be a new kind of cosmic explosion - a "hybrid gamma-ray burst" - which will be the subject of four articles to be published in the journal Nature on 21 December 2006.   view more (2006-12-21)

Study reveals molecular basis of botulism toxin's deadly activity
In the study, the scientists reveal the mysterious structural basis of the remarkably strong interaction that botulinum toxins form with nerve cells, a union so robust that a single toxin molecule can completely incapacitate a nerve cell.   view more (2006-12-18)

ESRF helps reveal the origin of the Solar System
Particles returned to Earth last January by the Stardust spacecraft from comet Wild 2 are yielding precious information about the origin of the solar system, thanks to the brilliant X-rays produced at several of the world's synchrotron facilities, including the ESRF.   view more (2006-12-18)

Advances in breast imaging
A diagnostic device that resembles a mammography unit can detect breast tumors as tiny as one-fifth of an inch in diameter, which may make it a valuable complementary imaging technique to mammography.   view more (2006-12-18)

Geologists finding a different Mars underneath
Scientists are finding an older, craggier face of Mars buried beneath the surface, thanks to pioneering sounding radar co-sponsored by NASA aboard the European Space Agency's Mars Express spacecraft.   view more (2006-12-14)

No matter their size black holes 'feed' in the same way
Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.   view more (2006-12-07)

High-resolution imaging with contrast agent shows promise in osteoarthritis research
An innovative combination of existing technologies shows promise for noninvasive, high-resolution imaging of cartilage in research on the progression and treatment of the common degenerative disease osteoarthritis.   view more (2006-12-05)

Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today.   view more (2006-12-04)

Radiologists attempt to solve mystery of Tut's demise
Egyptian radiologists who performed the first-ever computed tomography (CT) evaluation of King Tutankhamun's mummy believe they have solved the mystery of how the ancient pharaoh died.   view more (2006-11-28)

Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed.   view more (2006-11-28)

Nanoscale microscope sheds first light on gene repair
Proteins called H2AX act as "first aid" to DNA, among other roles. For the first time, scientists using the world's most powerful light microscope (the only one of its kind in the Americas) have seen how H2AX is distributed in the cell nucleus: in clusters, directing the first aid/repair... view more (2006-11-14)

Breaking the nanometer barrier in X-ray microscopy
Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height.   view more (2006-11-10)

Moon's Escaping Gasses Expose Fresh Surface
Conventional wisdom suggests that the Earth's moon has seen no widespread volcanic activity for at least the last 3 billion years. Now, a fresh look at existing data points to much more recent release of lunar gasses.   view more (2006-11-09)

Jefferson oncologists show less radiation just as effective in fighting brain tumor, saving hearing
Radiation oncologists at the Kimmel Cancer Center at Thomas Jefferson University and Thomas Jefferson University Hospital in Philadelphia have found that giving less radiation than usual is just as effective against a benign but potential devastating brain tumor called an acoustic schwannoma, and... view more (2006-11-08)
