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... 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)

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... 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.... 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... view more (2008-02-11)

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)

UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and... view more (2001-01-19)

European heat waves double in length since 1880
The most accurate measures of European daily temperatures ever indicate that the length of heat waves on the continent has doubled and the frequency of extremely hot days has nearly tripled in the past century.   view more (2007-08-06)

Plymouth launches new power source on the crest of a wave!
A team of European small companies and universities has been working together for the past 2 years to find a new way to harness the power of the waves. The team, which has been co-ordinated by PEP* at the University of Plymouth, has now launched an experimental Wave Energy Device in Plymouth. The... view more (2001-03-29)

Lisa And The Search For Elusive Gravity Waves
For almost 100 years, scientists have been searching for direct evidence of the existence of gravity waves - faint ripples in the fabric of spacetime predicted in Albert Einstein's theory of General Relativity.   view more (2005-03-31)

Scientists identify origin of hiss in upper atmosphere
Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts - belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to... view more (2008-03-06)

RIT Team Simulates First Merger of Three Black Holes on a Supercomputer
The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision.   view more (2008-04-09)

Slow brain waves play key role in coordinating complex activity
While it is widely accepted that the output of nerve cells carries information between regions of the brain, it's a big mystery how widely separated regions of the cortex involving billions of cells are linked together to coordinate complex activity.   view more (2006-09-15)

Steps towards warship invisibility
Naval warships might look like all-powerful vessels but they are also highly vulnerable to being spotted by the enemy.   view more (2008-03-03)

Disorder enables extreme sensitivity in piezoelectric materials
A research team working at the National Institute of Standards and Technology (NIST) has found an explanation for the extreme sensitivity to mechanical pressure or voltage of a special class of solid materials called relaxors.   view more (2008-05-19)

NRL measures record wave during Hurricane Ivan
Scientists at the Naval Research Laboratory-Stennis Space Center (NRL-SSC) measured a record-size ocean wave when the eye of Hurricane Ivan passed over NRL moorings deployed last May in the Gulf of Mexico.   view more (2005-08-05)

Mapping Orion's winds
For the past few months, Bob O'Dell has been mapping the winds blowing in the Orion Nebula, the closest stellar nursery similar to the one in which the sun was born.   view more (2006-01-11)

Advanced Aircraft to Probe Hazardous Atmospheric Whirlwinds
The nation's newest and most advanced research aircraft will participate in its first major mission March 1 through April 30, when it will study a severe type of atmospheric turbulence that forms near mountains and endangers airplanes.   view more (2006-03-02)
