General relativity survives gruelling pulsar test
Astronomers have used a pair of pulsars orbiting each other, found with CSIRO's Parkes telescope in 2003, to show that Einstein's theory of general relativity is correct to within 0.05% - the most stringent limit to date. view more (2006-09-18)
Expect a Warmer, Wetter World this Century, Computer Models Agree
Recent episodes of deadly heat in the United States and Europe, long dry spells across the U.S. West, and heavy bursts of rain and snow across much of North America and Eurasia hint at longer-term changes to come, according to a new study based on several of the world's most advanced climate models. view more (2006-10-23)
Graz team sheds new light on dark states - another Austrian breakthrough in quantum physics
Vienna, 16 June 2003 Light shines through opaque materials if certain conditions are met. By establishing the existence of another such condition, scientists at the Graz University of Technology have created additional possibilities for using light to control revolutionary new optical components. The project, funded by the Austrian Science Fund... view more... (2003-06-16)
MIT 'optics on a chip' may revolutionize telecom, computing
In work that could lead to completely new devices, systems and applications in computing and telecommunications, MIT researchers are bringing the long-sought goal of "optics on a chip" one step closer to market. view more (2007-02-06)
Slices of living brain tissue are helping scientists identify new stroke therapies
Slices of living human brain tissue are helping scientists learn which drugs can block the waves of death that engulf and engorge brain cells following a stroke. view more (2009-01-22)
Saturn's aurora - not as we thought! Comment from UK scientists
Results which combine data from the joint NASA/ESA/ASI Cassini Huygens space mission and the Hubble Space Telescope, published in Nature today (17th February 2005), reveal that Saturn's auroras, long thought to be a cross between those of Earth and Jupiter, are in fact different and may even be unique to Saturn. view more (2005-02-17)
British scientists create electron surf machine
By precisely controlling billions of individual electrons every second, they hope to develop new computing systems and increase the security of digital communication. view more (2007-06-13)
Astronomers catch a star being revved-up
Researchers have witnessed a star being transformed into an object that spins at almost 600 times a second using telescopes in the USA and the Netherlands, and CSIRO's Parkes telescope in Australia. view more (2009-05-22)
Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space. view more (2005-05-23)
Mayo Clinic real-time 3-D ultrasound speeds patient recovery
Mayo Clinic physicians have adapted real-time 3-D ultrasound imaging devices -- including one designed to look at an infant's heart -- so that they can watch as they use a needle filled with anesthetic to numb individual nerves located inches under the skin. In this way, they can quickly block nerve function in selected areas of the body prior to... view more... (2007-07-16)
Seats Helped Ancient Greeks Hear From Back Row
As the ancient Greeks were placing the last few stones on the magnificent theater at Epidaurus in the fourth century B.C., they couldn't have known that they had unwittingly created a sophisticated acoustic filter. view more (2007-04-05)
A new window on the universe
Using new tools to look at the universe, says Patrick Brady, often has led to discoveries that change the course of science. History is full of examples. view more (2007-11-16)
On a Wire or in a Fiber, a Wave is a Wave
In an experiment modeled on the classic "Young's double slit experiment" and published in the journal Nature Nanotechnology, researchers have powerfully reinforced the understanding that surface plasmon polaritons (SPPs) propagate and diffract just like any other wave. view more (2007-07-16)
Scientists cable seafloor seismometer into state earthquake network
A newly laid, 32-mile underwater cable finally links the state's only seafloor seismic station with the University of California, Berkeley's seismic network, merging real-time data from west of the San Andreas fault with data from 31 other land stations sprinkled around Northern and Central California. view more (2009-03-19)
Signs of ideal surfing conditions spotted in ocean of solar wind
Researchers at the University of Warwick have found what could be the signal of ideal wave "surfing" conditions for individual particles within the massive turbulent ocean of the solar wind. view more (2009-08-31)
A stress meter for fault zones
For the first time, scientists from Rice University, the Carnegie Institution of Washington, and the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have measured - in the field rather than in the laboratory - how changes in stress in rocks affect changes in the speed of seismic waves at depths where earthquakes... view more...

New NSF aircraft to probe hazardous atmospheric whirlwinds
Today, the nation's most-advanced research aircraft will take flight on its first science mission. Scientists aboard will study a severe type of atmospheric turbulence that forms near mountains and endangers planes flying in the vicinity. view more (2006-03-07)
Drawing inspiration from nature to build a better radio
MIT engineers have built a fast, ultra-broadband, low-power radio chip, modeled on the human inner ear, that could enable wireless devices capable of receiving cell phone, Internet, radio and television signals. view more (2009-06-04)
New 3-D ultrasound could improve stroke diagnosis, care
Using 3-D ultrasound technology they designed, Duke University bioengineers can compensate for the thickness and unevenness of the skull to see in real-time the arteries within the brain that most often clog up and cause strokes. view more (2008-04-25)
Computer vision for the blind
The white cane used by the blind as a travel aid may be universal, but it is not always adequate when it comes to pedestrian crossings. Although some crossings make a sound when it is safe to cross, many do not, and it is at these crossings that the blind need to know when the green man is showing. Adaptations of the white cane have been made,... view more... (2002-08-15)
