First results of the Narval trial (ANRS 088)
Patients with HIV infection may develop resistance to one or more of antiretroviral drugs to which they are exposed during treatment. The selection of the most appropriate drugs for switching therapy in patients who have developed resistance, is a difficult challenge. Both, genetic tests that identify mutations in viral genes associated with... view more... (2000-04-21)
Researchers using Arecibo Telescope discover never-before-seen pulsar blasts in Crab Nebula
Astronomers and physicists using the Cornell-managed Arecibo Telescope in Puerto Rico have discovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. This leads scientists to speculate this could be the first cosmic object with a third magnetic pole. view more (2007-01-09)
Imaging The Invisible: A New Look At Space Weather
How is it possible to image tiny particles that are normally invisible? What happens to our planet and its surroundings when huge solar storms collide with Earth's magnetic shield? These are just some of the questions that will be addressed this week during the UK/Ireland National Astronomy Meeting in Dublin. Our Earth is continually buffeted by a... view more... (2003-03-31)
Hinode: new insights on the origin of solar wind
Spectacular images and data from the Hinode mission have shed new light on the Sun's magnetic field and the origins of solar wind, which can disrupt power grids, satellites and communications on Earth. view more (2007-12-10)
Nano-competence for hard thin films
The good old magnetic disk drive is holding up well in the face of competition from optical storage media like CD-ROM and DVD and semiconductor flash and smart cards. Major advances are still being made, with typical storage densities doubling roughly every year and a half. When IBM launched the first magnetic disk drive on the market in 1956, it... view more...

Putting the heat on components
Europe's most modern facility for testing large, heat-resistant components used in fusion devices is now in operation at Max-Planck-Institut für Plasmapyhsik (IPP) in Garching near Munich. The special feature of GLADIS (Garching Large Divertor Sample Test Facility): The heat test facility is suitable for investigating not only small samples... view more... (2005-02-16)
Another McGill/JGH breakthrough opens door to early Alzheimer's diagnosis
A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH). view more (2009-06-17)
Hinode reveals new insights about the origin of solar wind
Images from NASA-funded telescopes aboard a Japanese satellite have shed new light about the sun's magnetic field and the origins of solar wind, which disrupts power grids, satellites and communications on Earth. view more (2007-12-07)
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 astronauts performing activities outside their... view more...

Routine diabetes screenings could cut health-care costs
Screening adults for diabetes could result in significant cost-savings for health care systems compared to the costs of not screening individuals at all. view more (2009-06-08)
BMI criteria for obesity surgery should be lowered, UT Southwestern researcher suggests
UT Southwestern Medical Center researchers have found that the existing body mass index criteria for obesity surgery often excludes a group of obese patients at risk of cardiovascular disease. view more (2007-12-18)
Television just got brighter: UCLA engineers are obsessed with the next generation of LEDs
Two researchers at the UCLA Henry Samueli School of Engineering and Applied Science want to make sure future generations of plasma TV watchers will see games like the upcoming NBA Finals in the brightest, most beautiful color possible - for a lot less money. view more (2007-05-17)
New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. view more (2008-05-15)
Getting ACL tears to heal themselves
A surgeon at Children's Hospital Boston may have found a better way to repair tears to the anterior cruciate ligament (ACL), a knee injury suffered by more than 100,000 Americans each year, particularly teenage girls. view more (2006-03-29)
Biomarkers may reduce need for biopsies
Data presented at this week's 28th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) suggest the potential of a significant impact of using biomarkers to reduce the need for biopsies and personalize transplant patient care. view more (2008-04-10)
Violent days on the Sun
On Tuesday 23 July 2002 space scientists recorded the largest of four powerful solar flares, all occurring in the space of just eight days. Solar flares are tremendous explosions in the atmosphere of the Sun, with the most powerful class, called the X class, capable of releasing as much energy as a thousand million megatonnes of high explosive.... view more...
