Wireless sensor networks offer high-tech assurance for a world wary of earthquakes
An earthquake strikes a large city, wrecking roads and bridges, stranding rush-hour commuters, trapping office workers inside high-rise buildings. view more (2006-04-07)
CT better than plain radiographs in diagnosing lumbar spine fractures
Lumbar spine fractures in a majority of patients with trauma can be detected by routine trauma abdomen and pelvis CT compared to plain radiographs, according to a recent study conducted by radiologists at the University of Cincinnati in Cincinnati, OH. view more (2007-05-07)
Magnetorheological fluids set to revolutionise dynamic vehicle suspension systems
Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. view more (2005-11-30)
Breakthrough Chip Delivers Better Digital Pictures For Less Power
The next advance in cameras is becoming a reality at the University of Rochester. Imaging chips revolutionized the photography industry, and now the chips themselves are being revolutionized. view more (2005-12-08)
Scientists cook up superfoam that fights back
Researchers at the University of Sheffield have transformed ordinary polyurethane packaging foam into a superfoam that not only refuses to be crushed but also actually increases in thickness when stretched. Under the same stresses conventional foam loses its resilience and its protective qualities, so the superfoam's benefits for the packaging... view more... (2002-12-18)
Vertebroplasty heals fractures but may cause others, Mayo Clinic study finds
A new Mayo Clinic study finds that vertebroplasty, a procedure used to treat painful compression fractures in the spinal vertebrae due to osteoporosis, appears to increase the risk for new fractures in adjacent vertebrae. view more (2006-01-17)
Jefferson Orthopaedic Surgeons Leading International Study of Timing of Spinal Surgery
When it comes to a devastating spinal injury, says spine surgeon Alexander Vaccaro, M.D., timing might be nearly everything. It's also a topic of great debate and discussion among orthopaedic surgeons. view more (2006-10-05)
Even a little cooling helps after cardiac arrest
As many as 400,000 people in North America suffer sudden cardiac arrest. Only 30% have their hearts restarted, and only about 6% survive to hospital discharge. Once the heart is restarted, a significant factor for subsequent death is brain injury. view more (2006-05-18)
Metal deformation studies lead to new understanding of materials at extreme conditions
By combining very large-scale molecular dynamics simulations with time-resolved data from laser experiments of shock wave propagation through specific metals, scientists at the Lawrence Livermore National Laboratory are now able to better understand the evolution of high-strain-rate plasticity. view more (2006-09-19)
Stretching bone marrow stem cells pushes them towards becoming blood vessel
When stretched, a type of adult stem cell taken from bone marrow can be nudged towards becoming the type of tissue found in blood vessels, according to a new study by bioengineers at the University of California, Berkeley. view more (2006-10-24)
Deft diving turtle tactics
How do turtles survive long trips across the ocean? At the Society for Experimental Biology conference on Friday 12 April Ms Corinne Martin (University of Wales Swansea) will present evidence of energy-saving diving patterns adopted by green turtles to survive long ocean trips. The turtles breed at Ascension Island, undertaking long-distance... view more... (2002-04-04)
Getting the feel of virtual reality
A giant leap forward in the realism of virtual reality (VR) may be just around the corner as a team of European researchers near the completion of a pioneering project to add textures, lighting effects and 'feel' to computer-generated 3D models. view more (2005-04-27)
Describing Soils: Calibration Tool for Teaching Soil Rupture Resistance
A new calibration tool was recently developed to help students and soil scientists calibrate their thumb and forefinger for the correct amount of pressure. view more (2009-01-06)
Green light for fusion energy with PetaWatt lasers
The production of fusion energy with a PetaWatt laser is a step closer now that a team of scientists from Japan and the UK has demonstrated that the physics works. Using the GEKKO XII laser system at the Osaka University in Japan, the team has successfully conducted experiments at laser powers equivalent to those required for a full-scale ignition... view more...

Smaller is Stronger - Now Scientists Know Why
As structures made of metal get smaller - as their dimensions approach the micrometer scale (millionths of a meter) or less - they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length. view more (2008-01-03)
Engineering to protect brittle bones
Leeds University engineer Dr Ruth Wilcox, 27, is on a mission - to help people with the brittle bone disease osteoporosis. She has just won a Post-Doctoral Research Fellowship from the Royal Academy of Engineering, starting 1 August, which will enable her to devote the next five years of her research to improving treatment of patients with... view more...

Two Dutch researchers analyse striking behaviour of websurfers
What behaviour do website visitors exhibit? Do they buy a specific product mainly on Mondays? Do they always return at a certain time of day? Being able to recognise and make use of such patterns is lucrative business for companies. view more (2008-10-30)
X-Ray Vision Of Violence In Interacting Galaxy Clusters
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: Ongoing research by an international team of astronomers is providing new insights into cataclysmic cosmic collisions between galaxy clusters. view more (2005-03-31)
Cartilage discovery offers arthritis hope
Scientists have revealed the intricate structure of cartilage in what they hope will provide clues to how the crippling joint disease osteoarthritis might one day be treated. view more (2007-01-11)
More rib fractures, but better survival rates
New findings show that the majority of people untrained in how to perform cardiopulmonary resuscitation, and even many trained emergency personnel, do not push with enough force to properly administer CPR. view more (2007-06-01)
