Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB). view more (2009-10-29)
Integral - tracking extreme radiation across the Universe
INFO 8-2002. Integral is the International Gamma Ray Astrophysics Laboratory of the European Space Agency. It is a cooperative mission with Russia and is scheduled for launch on 17 October 2002 from the Baikonur Cosmodrome, Kazakhstan, on a Russian Proton rocket, the Russian contribution to the programme. It is the world`s most advanced... view more... (2002-10-02)
Astronomers use gamma-ray burst to probe star formation in the early universe
The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. view more (2009-01-07)
UC Santa Cruz physicists eagerly await launch of NASA space telescope they helped build
When NASA launches its newest space observatory, physicists at the University of California, Santa Cruz, will be watching as the product of nearly 16 years of hard work blasts into orbit. view more (2008-05-30)
Lightning-produced radiation a potential health concern for air travelers
New information about lightning-emitted X-rays, gamma rays and high-energy electrons during thunderstorms is prompting scientists to raise concerns about the potential for airline passengers and crews to be exposed to harmful levels of radiation. view more (2009-12-08)
Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated - a finding that may help fine-tune therapies for depression. view more (2009-10-19)
NSF / NASA 'Firefly' CubeSat Mission to Study Link Between Lightning and Terrestrial Gamma Ray Flashes
Massive energy releases occur every day in the upper reaches of Earth's atmosphere. Lightning may give rise to these bursts of radiation. However, unlike the well-known flashes of light and peals of thunder familiar to Earth-dwellers, these energy releases are channeled upward and can be detected only from space. view more (2008-11-18)
Iowa State astrophysicists provide the eyes for new gamma ray telescope system
There's a "First Light Fiesta" in the works at Mt. Hopkins near Amado, Ariz. And Iowa State University astrophysicists will be among those enjoying the celebration of a new telescope system and all the science it will produce. view more (2007-04-20)
UO plays key role in LIGO's new view of a cosmic event
An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within... view more... (2008-01-04)
`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)
Integral reveals new class of 'supergiant' X-ray binary stars
ESA's Integral gamma-ray observatory has discovered a new, highly populated class of X-ray fast 'transient' binary stars, undetected in previous observations. view more (2005-11-17)
Gamma knife effective in treating trigeminal neuralgia
Research at the Comprehensive Cancer Center at Wake Forest University Baptist Medical has shown that Gamma Knife Stereotactic Radiosurgery (GKRS) is an effective treatment for trigeminal neuralgia, a common condition characterized by excruciating facial pain. view more (2005-10-20)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have discovered that Sgr A* produces rapid flares close to the... view more...

Fc gamma receptor gene variants associated with rheumatoid arthritis
People with a specific combination of variants of two genes, encoding two different receptors for the antibody Fc gamma, are three times more likely to develop rheumatoid arthritis than individuals with different variant combinations. view more (2005-11-10)
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)
Astronomers hot on the trail of nature's exotic flashers
Astronomers have uncovered tantalizing insights into the origin of short gamma-ray bursts - mysterious, split-second high-energy flashes that have eluded detailed study until now. view more (2005-05-31)
Scientists piece together the most distant cosmic explosion
In this week's issue of Nature, scientists at Penn State University and their U.S. and European colleagues discuss how this explosion, detected on 4 September 2005, was the result of a massive star collapsing into a black hole. view more (2006-03-09)
Three satellites needed to bring out 'shy star'
An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it view more (2005-07-14)
Progress in Diabetes Research
Scientists at the University of Cambridge have collaborated with a Cambridge-based biotechnology company to identify the gene responsible for a form of diabetes. The team working on the discovery believe it could eventually lead to the development of new drugs to treat the condition. Stephen O'Rahilly, Professor of Metabolic Medicine, and Krishna... view more... (1999-12-21)
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)
