Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system. view more (2008-08-07)
A scientific first: A supernova explosion is observed in real time
An ordinary observation with NASA's Swift research satellite recently led to the first real-time sighting of a star in the process of exploding. Astronomers have surveyed thousands of these supernova explosions in the past, but their observations have always begun some time after the main event is underway. view more (2008-05-22)
Scientists report study results from 'stealth' tsunami that killed 600 in Java last summer
Though categorized as magnitude 7.8, the earthquake could scarcely be felt by beachgoers that afternoon. A low tide and wind-driven waves disguised the signs of receding water, so when the tsunami struck, it caught even lifeguards by surprise. view more (2007-06-19)
German Government funds digital broadcasting in short, medium and long wave
The German Federal Ministry of Education and Research (bmb+f) will fund the project Radiomondo. During the next three years developments for Digital Radio Mondiale (DRM) will be supported with 3.9 million Euro. The project consortium consists of the Fraunhofer Institute for Integrated Circuits IIS-A, Deutsche Telekom AG, Robert Bosch GmbH, Sony... view more... (2002-01-11)
UCLA researchers develop biomarker for rapid relief of major depression
It is a long, slow slog to treat major depression. Many antidepressant medications are available, but no single biomarker or diagnostic test exists to predict which one is right for an individual. view more (2009-09-11)
Europe at the forefront in research on solar, wave and geothermal energies
Today at the "Solar platform" test site in Almeria (Spain) the European Commission presented the state of play on its research programmes in alternative energy sources, including solar thermal, wave and geothermal energy. World energy consumption will double over the next 50 years, with Europe currently depending heavily on foreign... view more... (2004-03-17)
Promising new metamaterial could transform ultrasound imaging
Using the same principles that help create a guitar's complex tones, researchers at the University of California, Berkeley, have developed a new material that holds promise for revolutionizing the field of ultrasound imaging. view more (2006-06-01)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
RIT study predicts how fast a black hole can be booted from a galaxy
Scientists have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger. view more (2007-05-31)
At the limits of the photoelectric effect
By way of the classical photoeffect, Einstein proved in 1905 that light also has particle character. However, with extremely high light intensities, remarkable things happen in the process. view more (2009-04-24)
New capture scenario explains origin of Neptune's oddball moon Triton
Neptune's large moon Triton may have abandoned an earlier partner to arrive in its unusual orbit around Neptune. view more (2006-05-11)
One gene provides fruit fly both antenna and color vision
A team of researchers that includes biologists from Washington University in St. Louis has discovered that a gene involved in the development and function of the fruit fly antenna also gives the organism its color vision. view more (2006-04-05)
Height of large waves changes according to month
"Anybody who observes waves can see that they are not the same height in winter and summer, but rather that their height varies over time, and we have applied a 'non- seasonal' statistical model in order to measure extreme events such as these", Fernando J. Méndez, an engineer at the Institute of Environmental Hydraulics at the... view more... (2009-06-01)
A mysterious change in the wave properties of electrons
The electrons of a perfect metallic surface move like free waves in a plane. Nevertheless, if atomic barriers are inserted, this may restrict their movement in one dimension, forming stationary waves such as those on the water surface in a bucket. view more (2004-09-30)
New findings contradict a prevailing belief about the inner ear
A healthy ear emits soft sounds in response to the sounds that travel in. Detectable with sensitive microphones, these otoacoustic emissions help doctors test newborns' hearing. A deaf ear doesn't produce these echoes. view more (2008-02-13)
Young Galaxy's Magnetism Surprises Astronomers
Astronomers have made the first direct measurement of the magnetic field in a young, distant galaxy, and the result is a big surprise. view more (2008-10-02)
Galaxy Zoo -- an Internet superstar
Since Galaxy Zoo's launch in July 2007, some 150,000 members of the public, inspired by the opportunity to be the first to see and classify a galaxy, have helped professional astronomers via this on-line mass-participation project to carry out real scientific research. view more (2008-09-02)
Supernova Imposter Goes Supernova
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006, professional and amateur astronomers witnessed the star... view more... (2007-04-05)
Safer shipping by predicting sand wave behaviour
Dutch researcher Joris van den Berg has developed a mathematical model to predict the movement of sand waves. Sand waves are formed by an interaction between the tidal current and sand. view more (2007-07-13)
Stormy Days Ahead for Coral Reefs
The increasing violence of storms under global climate change will have major effects on coral reefs - and has important implications for their future management. view more (2006-11-29)
