Where Broken DNA is Repaired
Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. view more (2007-08-03)
The cosmos is green: Researchers catch nature in the act of 'recycling' a star
For the first time, researchers have observed a singular cosmic act of rebirth: the transformation of an ordinary, slow-rotating pulsar into a superfast millisecond pulsar with an almost infinitely extended lifespan. view more (2009-05-22)
UVA researchers explain cell response to skin-damaging UV rays
It's well known that overexposure to ultraviolet rays from the sun can cause major skin problems, ranging from skin cancer to sunburns and premature wrinkles. A tan, for example, is nature's own UV protection and an unhealthy sign that your skin is damaged. view more (2007-10-02)
A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. view more (2009-04-06)
On October 10th at the Canaries the Magic telescope will be inaugurated: the biggest in the world for the study of gamma radiation
On October 10th the Magic Telescope (Major Atmospheric Gamma Imaging Cherenkov telescope) will be inaugurated. The telescope is located La Palma island, 2200 meters above the sea level at the Observatory Roque de los Muchachos, of the Itituto Astrofisico de Canarias. With his 17-meter-diameter-mirror and 240 square meters surface, it's the largest... view more... (2003-10-06)
Astronomers find record-old cosmic explosion
Using the powerful one-two combo of NASA's Swift satellite and the Gemini Observatory, astronomers from a number of institutions, including Johns Hopkins, have detected a mysterious type of cosmic explosion farther back in time than ever before. view more (2008-01-10)
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)
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)
`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space Science and Technology Center (NSSTC) in... view more... (2002-07-10)
Jupiter: A cloudy mirror for the Sun?
Astronomers using the European Space Agency's XMM-Newton telescope have discovered that observing the giant planet Jupiter may actually give them an insight in to solar activity on the far side of the Sun! In research reported in the most recent edition of Geophysical Research Letters, they discovered that Jupiter's x-ray glow is due to x-rays... view more... (2005-03-07)
Study gives clues to increasing X-rays' power
Three-dimensional, real-time X-ray images of patients could be closer to reality because of research recently completed by scientists at the University of Nebraska-Lincoln and a pair of Russian institutes. view more (2009-06-16)
XMM-Newton uncovers a celestial Rosetta stone
ESA's XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in a few million years. view more (2009-09-04)
How do we support today's Einsteins?
Is today's academic and corporate culture stifling science's risk-takers and stopping disruptive, revolutionary science from coming to the fore? view more (2009-04-02)
6 North American sites hold 12,900-year-old nanodiamond-rich soil
Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team. view more (2009-01-05)
Astrophysicists Solve Mystery in Milky Way Galaxy
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. view more (2009-07-09)
Dark energy -- 10 years on
Three quarters of our universe is made up of some weird, gravitationally repulsive substance that was only discovered ten years ago - dark energy. view more (2007-11-30)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is some 13 billion light years away, and we are... view more...

Dust clouds in cosmic cycle
It has been a mystery for astronomers how certain dying stars have their colossal quantities of material blown out into the universe and shrink into objects called "white dwarves". view more (2007-04-05)
Shedding light on the cosmic skeleton
"Matter is not distributed uniformly in the Universe," says Masayuki Tanaka from ESO, who led the new study. "In our cosmic vicinity, stars form in galaxies and galaxies usually form groups and clusters of galaxies. The most widely accepted cosmological theories predict that matter also clumps on a larger scale in the so-called... view more... (2009-11-03)
Doctors commonly fail to detect lung cancer on chest x-ray films
Failure to detect lung cancer on chest x-rays is not uncommon, reveals research in Postgraduate Medical Journal. The ensuing delay in diagnosis and the start of treatment may contribute to some of the lowest survival rates in Europe for the disease, say the authors. view more (2002-03-04)
