Glacial advances
The vast majority of the world's glaciers are retreating as the planet gets warmer. But a few, including glaciers south of the equator in South America and New Zealand, are inching forward. view more (2009-05-04)
UI researchers discover star orbiting a 'medium-sized' black hole
University of Iowa researchers have found a star orbiting a "medium-sized" black hole - about 1,000 times more massive than the sun - in the nearby starburst galaxy M82, a development that may help explain how medium-sized black holes form and evolve. view more (2006-01-06)
New Instruments To Picture The Early Universe
The latest instrument of the UK's Tenerife Cosmic Microwave Background Experiment, has been officially inaugurated at the mountain top Teide Observatory of the Instituto de Astrofisica de Canarias, IAC, on Tenerife. The ceremony coincided with the announcement by the PPARC of major support for a new telescope of unmatched sensitivity.... view more... (1996-07-03)
Record: fastest flashing star
Dutch researcher Steve van Straaten set a record during his doctoral research. The researcher registered the fastest ever change in the X-ray emission originating from a binary star. The record-breaking binary star consists of a neutron star and a lighter companion star. Astronomer Steve van Straaten studied the time variations in the X-ray... view more... (2004-05-07)
Tiny lasers get a notch up
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. view more (2009-01-23)
Hubble repair mission carrying $70 million CU-Boulder instrument on track for May 11 launch
A $70 million instrument designed by the University of Colorado at Boulder to probe the evolution of galaxies, stars and intergalactic matter from its perch on the orbiting Hubble Space Telescope is on schedule for its slated May 11 launch from Kennedy Space Center in Florida aboard NASA's space shuttle Atlantis. view more (2009-05-08)
Green light for Lazio-Sirad: the experiment on the International Space Station that will chase earthquakes
Lazio-Sirad is ready to gather data. The experiment is installed on the International Space Station and its aim is to trace the slight variations of the so-called Van Allen belts that seem to occur before earthquakes. At the same time the experiment will gather data that will make possible the development of techniques of protection from radiation... view more... (2005-04-14)
Chandra discovers cosmic cannonball
One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed. view more (2007-11-29)
Cookie cutter in the sky
Black holes can now be thought of as donut holes. The shape of material around black holes has been seen for the first time: an analysis of over 200 active galactic nuclei-cores of galaxies powered by disks of hot material feeding a super-massive black hole-shows that all have a consistent, ordered physical structure that seems to be independent... view more...

Chest X-ray exposure may increase likelihood of breast cancer
An analysis of 1,600 women with BRCA 1/2 mutations suggests that exposure to chest X-rays may increase the risk of breast cancer, and that exposure before the age of 20 may be linked to particularly heightened risk. view more (2006-06-27)
Cosmologists 'see' the cosmic dawn
The images, produced by scientists at Durham University's Institute for Computational Cosmology, show the "Cosmic Dawn" - the formation of the first big galaxies in the Universe. view more (2009-02-11)

Cosmic impacts and civilisation collapse @ the London Catastrophes meeting
At some time around 2300 BC, a large number of the major civilisations of the world collapsed, simultaneously it seems. The Akkadian Empire in Mesopotamia, the Old Kingdom in Egypt, the Early Bronze Age civilisation in Israel, Anatolia and Greece, as well as the Indus Valley civilisation in India, the Hilmand civilisation in Afghanistan and the... view more...

New technique measures chemical composition of tiny details
The method which the Eindhoven have developed is based on the radiation emitted by an object when it is irradiated by a beam of electrons. The measurable phenomenon occurs because the electrons in the beam collide with electrons in the atoms making up the object so that they enter an excited state. When the electrons return to the free state, with... view more... (2000-01-18)
IAU0916: The violent youth of solar proxies steer course of genesis of life
One of the hottest topics at this year's XXVIIth General Assembly of the International Astronomical Union (IAU) in Rio de Janeiro, Brazil involves the study of the astrophysical conditions favourable for the development and survival of primordial life. view more (2009-08-11)
UCLA study helps ER physicians identify previously undetectable spinal injuries
A new national study indicates that patients with a cervical spinal injury (CSI) may harbor additional spinal damage not visible on regular x-rays. view more (2005-09-07)
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)
Chandra looks back at the Earth
In an unusual observation, a team of scientists has scanned the northern polar region of Earth with NASA's Chandra X-ray Observatory. view more (2005-12-30)
Supercomputer could throw light on 'mysterious' dark energy
Cosmologists have run a series of huge computer simulations of the Universe that could ultimately help solve the mystery of dark energy. view more (2008-01-11)
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)
