Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material.
With the new hydrogen tablet, it becomes much simpler to use the environmentally-friendly energy of hydrogen. Hydrogen is a non-polluting fuel, but since it is a light gas it occupies too much volume, and it is flammable. Consequently, effective and safe stor
An oxygen-free ocean from bottom to surface is probably the worst scenario that marine higher life can experience. Are processes and feedbacks linking the atmosphere to the deep ocean capable to cause a rapid change from an oxygen-rich to an oxygen-free deep ocean? And what are the consequences for the global carbon cycle that ultimately drive marine and terrestrial ecosystems and climate variation?
These are fundamental and burning questions on the society’s agenda. Hurricane
A new study from the University of Edinburgh and Pennsylvania State University suggests a smart solution to one of the biggest challenges facing the optics and electromagnetics sector – how to produce near-perfect lenses cheaply.
Researchers have devised a strikingly simple method of producing materials which bend light the ’wrong’ way – a significant development as lenses with minimal distortion can be made from flat slabs of these negatively-refracting materials.
Concerns over the privacy of patients could be hampering efforts to spot disease clusters and monitor the health effects of environmental pollution, according to researchers in the latest edition of the Journal of Biomedical Informatics.
Data made available to research groups investigating everything from cancer clusters to the risk of living near to hazardous waste sites is often restricted, altered or aggregated in order to protect the identity of individual patients.
Eine von der Universität Augsburg und Georgeson Shareholder veröffentlichte Studie zeigt: Unternehmen setzen bei Aktionärsbetreuung und Kapitalmarktkommunikation verstärkt auf zielgruppenspezifische Maßnahmen.
Zielgruppenorientierte Investor Relations (IR) gewinnen zunehmend an Bedeutung. Zu diesem Ergebnis kommt eine Trendstudie, die Georgeson Shareholder, ein Unternehmen der Computershare Gruppe, heute gemeinsam mit der Universität Augsburg veröffentlicht hat. Die Untersuchung ze
Researchers at Westmead Millennium Institute have discovered a safe, non-surgical method of identifying brain infections such as brain abscess, and an accurate and rapid way of diagnosing meningitis.
Several hundred serious brain infections such as abscesses and meningitis are diagnosed in Australians every year. Neurological infections require immediate identification and treatment, however doctors have always faced difficulty in accurately and rapidly diagnosing an infection, in
Researchers calculated the costs of management of low back pain and found that an integrated and step-wise approach within a multidisciplinary setting forms a better use of the available resources. The study is published in the September issue of Pain Practice.
Within a multidisciplinary pain center, treatment possibilities include pharmacological treatment, rehabilitation programs, cognitive behavioral therapy, psychological counseling, as well as minimally invasive interventional
Researchers propose plan for resolution
A group of Israeli, Palestinian and French scientists have proposed a possible management solution to ameliorate the water quality crisis depriving residents of drinkable water in the Gaza Strip. The study is published in the September-October 2005 issue of the journal Ground Water. This special theme issue contains 14 papers on transboundary ground water.
Israel and the Palestinian Authority share the Southern Mediterranean Coas
New research shows that bacteria lurking in household dust produce chemicals that may trigger asthma and asthma-related symptoms such as wheezing. These bacterial chemicals, called endotoxins, particularly those found on bedroom floors, were linked with increased respiratory problems in adults. This study, supported by the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health, is the first nationwide study of endotoxins in the household envir
A major breakthrough in the use of molecules as information processors is to be announced at this year’s BA Festival of Science in Dublin.
Nanotechnology experts are exploring the capabilities of molecules that act like conventional computers but can operate in tiny places where no silicon-based chip or semiconductor can go. Now, for the first time, they have used these molecules to perform logic operations and process information in spaces a few nanometres across.
National study calls for more use of CT scans in evaluating spinal injury
A new national study indicates that patients with a cervical spinal injury (CSI) may harbor additional spinal damage not visible on regular x-rays. In fact, more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly.

Registry Sheds Light on Procedure’s Risks and Benefits
Episodes of dangerously low blood glucose, or hypoglycemia, were greatly reduced in people who received an islet transplant for poorly controlled type 1 diabetes, according to an analysis of outcomes in 138 patients who had the procedure at 19 medical centers in the United States and Canada. This is one of the conclusions of the Collaborative Islet Transplant Registry (CITR), which tracks many factors affecting the success o
ACTIVE-A and ACTIVE-I to continue
Study treatments for the ACTIVE W trial of the ACTIVE (Atrial Fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events) program have been discontinued due to a significant difference in efficacy, in favour of the standard oral anticoagulation (OAC) over antiplatelet therapy (clopidogrel plus aspirin).
The ACTIVE trial, the largest randomised international trial program ever conducted in atrial fibrillation (AF), was
A new solar-powered underwater robot technology developed for undersea observation and water monitoring will be showcased at a Sept. 16 workshop on leading-edge robotics to be held at the National Science Foundation (NSF) in Arlington, Va.
Arthur C. Sanderson, professor of electrical, computer, and systems engineering at Rensselaer Polytechnic Institute, will display the robotic technology being developed by a team of research groups, including Rensselaer, and led by the Autonomou
Research published in Science demonstrates the value of high-throughput sequencing in small RNA analysis
Solexa, Inc. (Nasdaq: SLXA) today announced that its researchers in collaboration with the Delaware Biotechnology Institute and the University of Delaware reported the most comprehensive analysis to date of the small RNA component of the transcriptome. The research, “Elucidation of the Small RNA Component of the Transcriptome,” was published in the September 2, 2005 issue of t
The surface of comet Tempel 1, hit by a NASA space probe during a spectacular July 4 experiment, bears evidence of impact craters, suggesting that the comet has collided with asteroids or other space travelers in its journeys around the Sun.
Several dozen circular features that appear to be impact craters, ranging from 40 to 400 meters across, were spotted on Tempel 1 during the Deep Impact mission, according to first results from the mission team published by Science and released
