Why oceans behave like water in a bath
SATELLITE measurements of sea levels have uncovered a bizarre effect. The sea seems to be rising faster near the coast than in mid-ocean. Simon Holgate and Philip Woodworth of the Proudman Oceanographic Laboratory, in Bidston, UK, found this discrepancy using the Topex satellite, launched in 1992. The satellite measures sea level by bouncing... view more... (2004-04-21)
Mathematicians provide new insight into tsunamis
A new mathematical formula that could be used to give advance warning of where a tsunami is likely to hit and how destructive it will be has been worked out by scientists at Newcastle University. view more (2009-04-01)
Mind the gap: Space scientists uncover causes of gap in Van Allen belts
A team of British and US scientists have discovered that the gap in the Van Allen radiation belts is formed by natural wave turbulence in space, not by lightning. view more (2006-09-27)
Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. view more (2007-05-04)
Light from wind and waves
Engineers of PROEKTSTROYSERVIS (Kaliningrad) know how to make the stormy sea work. They have designed a unique sea-based wind-and-wave plant, which allows to convert the energy of wind and waves into electricity. The plant is not afraid of any storms. In appearance, the entire construction is reminiscent of a float, UFO or the restaurant in the... view more... (2003-08-22)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Livermore researchers find
With the exception of lasers and free-electron lasers, there hasn't been another fundamental way to produce coherent light for close to 50 years. view more (2006-01-16)
Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. view more (2007-05-30)
Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. view more (2006-12-04)
How to make microwaves on a chip to replace X-rays for medical imaging and security
Is microwave radiation the nondestructive imaging technology of the future? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionizing damage caused by X-rays. view more (2008-05-30)
GEO600 starts continuous search for Gravitational Waves
The joint German-British Gravitational Wave Detector GEO600 has now entered an 18-month run of continuous measurement. view more (2006-06-27)
Engineers ride 'rogue' laser waves to build better light sources
A freak wave at sea is a terrifying sight. Seven stories tall, wildly unpredictable, and incredibly destructive, such waves have been known to emerge from calm waters and swallow ships whole. view more (2009-03-06)
Starquakes reveal stellar secrets
Looking into the interior of the Earth or the Sun is a bit similar to examining a baby in its mother`s womb using an ultrasound scan. Light cannot penetrate the area, so we make pictures in these cases using sound waves, which human ears cannot hear. With SOHO, ESA has probed deeply into the Sun using the sound-waves principle, and with great... view more... (2002-08-14)
SECCHI team obtains images of the solar wind at Earth
Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA's Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth. view more (2007-12-10)
Processing seismic waves emanating from the ocean bottom
Iban Rodr'guez Barbarin, a telecommunications engineer from Pamplona, has carried out a study on processing seismic waves emanating from the ocean's floor. view more (2003-11-25)
The Radar Search For Martian Water
Until the last few years, Mars has been regarded as a cold, arid world that lost most of its water long ago. However, recent observations by NASA's Mars Global Surveyor and Mars Odyssey spacecraft have provided tantalising evidence that huge amounts of water may be hidden just below the surface. Now, a powerful new instrument is poised to probe... view more... (2003-04-01)
Listening for the cosmic symphony: New SU supercomputer will help scientists listen for black holes
Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole. The supercomputer, dubbed SUGAR (SU Gravitational and Relativity Cluster), will soon receive massive amounts of data from the California Institute of Technology (Caltech) that was collected... view more...

Big quakes spark jolts worldwide
Until 1992, when California's magnitude-7.3 Landers earthquake set off small jolts as far away as Yellowstone National Park, scientists did not believe large earthquakes sparked smaller tremors at distant locations. view more (2008-05-27)
Killer electrons in space are now less mysterious
A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding. view more (2007-07-27)
Running shipwreck simulations backwards helps identify dangerous waves
Big waves in fierce storms have long been the focus of ship designers in simulations testing new vessels. view more (2007-10-02)
