Iowa State astrophysicists provide the eyes for new gamma ray telescope system
04-19-2007 · EurekAlert!Iowa State University researchers built the four cameras for the VERITAS telescope system in Arizona. The new $20 million telescope system detects gamma rays and will help astrophysicists explore distant regions of space, look for evidence of dark matter and help explain the origins of the most energetic radiation in the universe.

- New VERITAS telescope array may help find 'dark matter'
04-30-2007 · EurekAlert!
Scientists in the Northern Hemisphere have opened a new window on the universe allowing them to explore and understand the cosmos at a much higher level of precision than was previously available. Think of it as acquiring a new pair of glasses that allow you to see more clearly. These new "glasses" are VERITAS, (the Very Energetic Radiation Imaging Telescope Array System), a major new ground-based gamma-ray observatory, designed to provide an in-depth examination of the universe.

- Astronomers discover new kind of black-hole explosion
12-20-2006 · EurekAlert!
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. The scientists include four astrophysicists at Penn State University as well as others around the globe. The nature of the explosion is a puzzle in "virtually uncharted territory" for space scientists.

- Why our shifty eyes don't drive us crazy
11-08-2006 · EurekAlert!
Our eyes are constantly making saccades, or little jumps. Yet the world appears to us as a smooth whole. Somehow, the brain's visual system "knows" where the eyes are about to move and is able to adjust for that movement. In a paper published online this week in Nature, researchers at the University of Pittsburgh and the National Eye Institute for the first time provide a circuit-level explanation as to why.

- Arizona State scientists keep an eye on Martian dust storm
07-11-2007 · EurekAlert!
Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. The dust storm, which erupted during the last week of June 2007, is affecting operations for all five spacecraft operating at Mars: two NASA rovers on the ground plus three orbiters, two of which belong to NASA and one to the European Space Agency.

- New treatment for glaucoma shows promise in laboratory, say Iowa State researchers
08-01-2007 · EurekAlert!
Iowa State University researchers developed a new technique that successfully treated rats for blindness caused by glaucoma. They previously determined that animals with glaucoma increase production of neurotrophins in an attempt to shield against blindness. They imitated that process in the laboratory, modifying bone marrow-derived stem cells and transplanting them into the eyes. Their experimental treatment will be used on dogs in the next year. If successful, it is expected to move to human trials.

- Matter flashed at ultra speed
06-12-2007 · EurekAlert!
Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999 percent of the velocity of light, the maximum speed limit in the universe.

- GROND takes off
07-07-2007 · EurekAlert!
A new instrument has seen first light at the ESO La Silla Observatory. Equipping the 2.2-m MPI/ESO telescope, GROND takes images simultaneously in seven colors. It will be mostly used to determine distances of gamma-ray bursts.

- Worldwide effort bringing ALMA telescope into reality
02-15-2008 · EurekAlert!
In the thin, dry air of northern Chile's Atacama Desert, at an altitude of 16,500 feet, an amazing new telescope system is taking shape, on schedule to provide the world's astronomers with unprecedented views of the origins of stars, galaxies, and planets. The Atacama Large Millimeter/submillimeter Array will open an entirely new "window" on the Universe, allowing scientists to unravel longstanding and important astronomical mysteries.

- Gamma-ray birth cries suggest massive magnetic engines
03-08-2007 · EurekAlert!
A gamma-ray burst observed by NASA's Swift satellite on July 29, 2006, generated an X-ray afterglow that remained detectable to the spacecraft's X-ray Telescope (XRT) for 125 days -- an astonishing long time -- indicating the possible formation of a magnetar. If Chandra or XMM-Newton can see the afterglow later this year, GRB 060729 will break the record for longest observed X-ray afterglow.

- Biodegradable microspheres deliver time release vaccines, stimulate different immune response
02-28-2007 · EurekAlert!
A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not. Researchers from Iowa State University report their findings today at the ASM Biodefense and Emerging Disease Research Meeting.
