Sunquakes Reveal The Solar Furnace
Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet. In the same way, astronomers are now able to measure millions... view more...

General relativity survives gruelling pulsar test — Einstein at least 99.95 percent right
An international research team led by Prof. Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has used three years of observations of the "double pulsar", a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein's theory of general relativity-the theory of gravity that... view more...

New study shows earthquake shaking triggers aftershocks
A new analysis of earthquake data indicates that aftershocks are triggered by the shaking associated with the mainshock, rather than by the added stress on nearby faults resulting from rearrangement of the Earth's crust. view more (2006-06-08)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
Female supervisors more susceptible to workplace sexual harassment
Women who hold supervisory positions are more likely to be sexually harassed at work, according to the first-ever, large-scale longitudinal study to examine workplace power, gender and sexual harassment. view more (2009-08-10)
Hyper-accurate clocks - the beating heart of Galileo
Travellers have relied on accurate timekeeping for navigation since the development of the marine chronometer in the eighteenth century. view more (2007-05-11)
Using light under your skin
You have a tiny wound on your hand that doesn't heal, a bad burn on your chest - or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope for an improved and totally harmless method to peer... view more... (2005-04-21)
Europe could ride the wave of Ocean Energy
Up to 20 million homes in Europe could be powered by clean renewable energy from the sea, according to ocean energy expert Teresa Pontes of Portugal, who was speaking at the EurOCEAN marine science and policy event in Galway today (12th May). She estimated that, by harnessing energy from waves and marine currents, Europe would produce around 200... view more... (2004-05-12)
ESA to look for the missing link in gravity
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency (ESA) hopes to get to the very bottom of it. Scientists will study space... view more... (2002-09-11)
Study links low-frequency hearing to shape of the cochlea
Shape matters, even in hearing. Specifically, it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important. view more (2008-04-28)
The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. view more (2008-04-16)
Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean. view more (2007-04-13)
Optical imaging added to ultrasound improves breast cancer diagnosis
A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions-and potentially reduce the number of breast biopsies performed. view more (2005-09-27)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
New sonofusion experiment produces results without external neutron source
A team of researchers from Rensselaer Polytechnic Institute, Purdue University, and the Russian Academy of Sciences has used sound waves to induce nuclear fusion without the need for an external neutron source. view more (2006-01-30)
Fortuitous research provides first detailed documentation of tsunami erosion
Tsunamis are among the most-devastating natural calamities. These earthquake-generated waves can quickly engulf low-lying land and bring widespread destruction and death. They can deposit sand and debris far inland from where they came ashore. view more (2009-10-28)
Simulations Illuminate Universe's First Twin Stars
The earliest stars in the universe formed not only as individuals, but sometimes also as twins, according to a paper published today in Science Express. view more (2009-07-10)
US satellite protection scheme could affect global communications
A proposed US system to protect satellites from solar storms or high-altitude nuclear detonations could cause side-effects that lead to radio communication blackouts, according to new research. view more (2006-08-15)
Seismic Noise Unearths Lost Hurricanes
Seismologists have found a new way to piece together the history of hurricanes in the North Atlantic - by looking back through records of the planet's seismic noise. It's an entirely new way to tap into the rich trove of seismic records, and the strategy might help establish a link between global warming and the frequency or intensity of... view more...

Hair-sized lens helps look in blood vessels
A tiny measurement system that incorporates a lens as thick as two human hairs has been developed by researchers to investigate the force exerted on the wall of an artery as blood whooshes past. In a research paper published today in the Institute of Physics publication Journal of Micromechanics and Microengineering, Dr Rob Keynton and colleagues... view more... (2002-03-20)
