A group of international researchers plans to use studies by land and by sea to determine the size and shape of an underground magma chamber beneath an active volcano, which will help improve the ability to assess hazards and forecast volcanic events.
“We can look at changes on the surface and infer what is happening at depth, but we don’t know the physical dimensions,” said Glen Mattioli, professor of geosciences at the University of Arkansas.

New c.cam gamma camera provides new angle in cardiology diagnosis
Siemens Medical Solutions today announced that its c.cam – a unique, reclining dedicated cardiac gamma camera system – will be available for the European market. Introduced at the annual meeting of the American Society of Nuclear Cardiology 2003, the rising number of nuclear applications in Europe also requires a gamma camera system specialized for examinations of the heart.
The c.cam’s myocardial viabili
New insights by Duke University Medical Center researchers as to how HIV evades the human immune system may offer a new approach for developing HIV vaccines. The findings suggest some HIV vaccines may have failed because they induce a class of antibodies that a patient’s own immune system is programmed to destroy.
The Duke team discovered that certain broadly protective antibodies, which recognize and latch onto the HIV protein gp41, resemble antibodies made in autoimmune disea
Farmers growing genetically modified rice in field trials in China report higher crop yields, reduced pesticide use and fewer pesticide-related health problems, according to a study by researchers in China and at Rutgers University and the University of California, Davis. Results of the study will appear in the April 29 issue of the journal Science.
“This paper studies two of the four GM varieties that are now in farm-level preproduction trials, the last step before commerciali
Duke University physicists have developed a switching technique that uses a very weak beam of light to control a much stronger beam. The achievement could make optical telecommunications devices perform far more efficiently, and perhaps also aid in the development of futuristic quantum communications devices, the scientists said. “What’s important here is that this is an ’all-optical’ switch, using only light, with a weak beam affecting a strong one,” said physics professor Daniel Gauthier,
Using satellites, data from buoys and computer models to study the Earth’s oceans, scientists have concluded that more energy is being absorbed from the Sun than is emitted back to space, throwing the Earth’s energy “out of balance” and warming the planet.
Scientists from the National Aeronautics and Space Administration (NASA) (Washington, D.C.), The Earth Institute at Columbia University (New York), and Lawrence Berkeley National Laboratory (California) have confi
Science article details trends in river restoration
A group of leading river scientists published a paper in the journal Science today, presenting first-of-its-kind research on the state of river restoration in the United States. Following on the heels of a related article published in the Journal of Applied Ecology that describes the five fundamental standards for ecologically sustainable river restoration, the papers document the maturing effort to reverse rising pollution level
How does cholesterol in our diets end up as artery-clogging plaque that can cause heart attacks and strokes? Research in animals suggests that a little-studied enzyme may play a major role – and that drugs to target it could dramatically reduce the risk of cardiovascular disease.
Lawrence Rudel, Ph.D., from Wake Forest University School of Medicine, presented new results from his research on ACAT2, a cholesterol transforming enzyme, today at the American Heart Association’s
Open source software (OSS) should be considered as a matter of course in the IT procurement process at universities, says Randy Metcalfe, Communications Manager at OSS Watch, a national advisory service based at the University of Oxford.
Speaking at the AURIL conference in Edinburgh on 29 April, Metcalfe said:
“Interoperability and flexibility are two key reasons why higher education institutions should be looking at open source software alternatives alongside proprietary opt
Imagine a car engine that saves you gas money and protects the environment. That may soon be a reality. Researchers at Karstad University in Sweden, working with the Swedish company Mecel, have developed a new method to make internal combustion engines more efficient and environmentally friendly.
To be able to tune internal combustion engines optimally, information is needed from the combustion process in the engine’s cylinders. This isn’t easy, because it’s hard
Everyone’s lives are touched by cancer – it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.
This was the key message to come from an event today (28th April) which brought together 130 leading healthcare professionals and physicists. Speaking at “The Future of Medical Imaging and Radiot
Why do some cancer cells divide not into two, as cells are supposed to do in mitosis, but into three-four new cells that look thoroughly abnormal? This question was raised as early as the 1890s by the German tumor researcher David Hansemann, who could observe the strange mitosis even using the microscopes of his day. Now another David, Lund University researcher David Gisselsson, has found an answer.
Together with associates from the Section for Clinical Genetics, David Gissels
A multidisciplinary centre launched today will promote a far broader understanding of the role sugars play in human disease, scientists say.
Focused on glycobiology, the study of how sugars in human cells affect our biology, researchers hope it will accelerate the development of therapies for diseases such as HIV, cancers and muscular dystrophy.
The Glycobiology Training, Research and Infrastructure Centre (GlycoTRIC), established at Imperial College London, will promo
New software to speed up image processing could save the broadcasting industry millions of euros and could even be used to enable remote surgery, where a surgeon in one country performs on a patient in another country.
The Nuggets project successfully created a software layer that will allow real-time networks to be used in broadcasting. “Broadcasting demands a very high Quality of Service (QoS), but up to now transfer speeds across networks were too slow for broadcasting applicat
A recently completed clinical study has found new prognostic markers that may help clinicians identify those children with leukaemia who are at high risk of relapse and are most in need of intensified treatment to improve their chance of survival.
The retrospective clinical study, performed jointly by the Centre for Children’s Cancer and Blood Disorders (CCC&BD)at Sydney Children’s Hospital and Children’s Cancer Institute Australia, was recently published in the in
Observers in eastern Arkansas have reported at least eight independent sightings of a bird that appears to be an ivory-billed woodpecker, a species widely thought to be extinct. A video clip of one bird, though blurry, shows key features, including the size and markings, indicating that the bird is indeed an ivory-billed woodpecker, according to John W. Fitzpatrick of Cornell University and coauthors of a paper released online today by Science.
