Non-coding RNAs help silence the mammalian transcription
Dr. Shirley Tilghman and colleagues (Princeton University) lend new insight into the mechanism of genomic imprinting, demonstrating a necessary role for a non-coding RNA transcript in the silencing of an imprinted gene cluster in mice.   view more (2006-05-15)

UK Astronomers look forward to looking back
When NASA launches its Space Infrared Telescope Facility (SIRTF) - the agency's fourth 'Great Observatory' - later this week, astronomers around the world will be looking forward to using one of the most powerful time machines ever built. Among those anticipating the opportunity to look back billions of years to an era when the universe was in its... view more... (2003-08-19)

NASA's Chandra sees brightest supernova ever
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes.   view more (2007-05-08)

The Mouse That Roared: Pipsqueak Star Unleashes Monster Flare
On April 25, NASA's Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable in the night sky at the time.   view more (2008-05-20)

University Computer Cluster To Help Heart Health And Cancer Patients
A new computer cluster funded by the University of Sheffield and located within the Royal Hallamshire Hospital, will help scientists to improve their understanding of how human cells and organs work. This will ultimately lead to more effective ways of treating cardiovascular disease and cancer as well as other diseases. It will also eventually... view more... (2004-06-17)

Study establishes new class of cancer-causing genes
Over the past few years, scientists have discovered that a new class of genetic regulators called "microRNAs" influences normal human growth and development. Now, researchers have found that microRNAs also play an important role in human cancer.   view more (2005-06-08)

Astronomers search for orphan stars using newly upgraded telescope
Using new charge coupled device (CCD) instrumentation, Case Western Reserve University astronomers can now view the night sky wider and deeper than before.   view more (2008-05-20)

Chandra independently determines Hubble constant
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory.   view more (2006-08-10)

New Star Systems First of Their Kind
Researchers funded by the National Science Foundation (NSF) announced today in Astrophysical Journal Letters that they have discovered a faraway binary star system that could be the progenitor of a rare type of supernova.   view more (2008-04-02)

Missing planets attest to destructive power of stars' tides
During the last two decades, astronomers have found hundreds of planets orbiting stars outside our solar system. New research indicates they might have found even more except for one thing - some planets have fallen into their stars and simply no longer exist.   view more (2009-04-28)

Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems.   view more (2005-03-31)

Hazy red sunset on extrasolar planet
A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with Hubble's Advanced Camera for Surveys (ACS).   view more (2007-12-11)

CSI: Milky Way team works scene of dead star
Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more intense than Earth's.   view more (2008-05-29)

Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time that associated dust has been detected. The... view more... (2005-03-30)

Hubble sees dark matter ring in a galaxy cluster
A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster.   view more (2007-05-17)

European team finds smallest transiting extrasolar planet ever
The CoRoT satellite has discovered a planet only twice as large as the Earth orbiting a star slightly smaller than the Sun. It is the smallest extrasolar planet (planet outside our solar system) whose radius has ever been measured.   view more (2009-02-03)

100th Extra-solar planet gives clues to origins of planets
British astronomers, together with Australian and American colleagues, have used the 3.9m Anglo-Australian Telescope [AAT] in New South Wales, Australia to discover a new planet outside our Solar System - the 100th to be detected. The discovery, which is part of a search for solar systems that resemble our own, will be announced today (Tuesday) at... view more... (2002-09-16)

Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected.   view more (2007-05-31)

Scientists Discover Magnetic Superatoms
A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table - that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage.   view more (2009-06-16)

Hubble finds ring of dark matter
Astronomers have long suspected the existence of the invisible substance of dark matter as the source of additional gravity that holds together galaxy clusters.   view more (2007-05-16)
