Search for missing galaxies in high-speed galactic gas clouds ’comes up empty,’ Pitt researcher finds
A team of astronomers from the University of Pittsburgh and the Universitäts-Sternwarte München in Munich, Germany, announced today in a paper presented at the meeting of the American Astronomical Society in Washington, D.C., that their search for dwarf galaxies in fast-moving clouds of gas has yielded no results, leading them to suggest alternative avenues of research
One in five patients taking diuretics commonly prescribed for high blood pressure or heart conditions end up with reduced sodium and potassium levels, according to a study published in the January issue of the British Journal of Clinical Pharmacology.
Yet recent evidence suggests that perhaps as few as a third of patients on the drugs – used by one in eight adults – have their electrolyte levels tested, despite the fact that reduced levels can lead to a wide range of health
It is commonly believed that carbohydrates, particularly sugar, are a cause of insulin resistance and type 2 diabetes. However, such thinking has been challenged following the publication of a thorough appraisal of the evidence, in the latest edition of Nutrition Research Reviews.
Dr Neville McClenaghan, from the University of Ulster , conducted a large review of scientific studies investigating the effect of high and low carbohydrate diets on blood glucose control in people with and wi
Are you exceptionally creative when it comes to technology? Or do you know a woman that is? Britain’s top creative women will be celebrated at the upcoming 7th Annual British Female Inventors and Innovators Awards Ceremony in London on 21 February 2006.
There is a special award category aimed at Information Technology, Electronics and Communication (ITEC). This category was set up by the European funded project ’Equalitec – Advancing women in ITEC’ and aims to promote
One of the most striking predictions of Einstein’s theory of special relativity is probably the best known formula in all science: E = mc2. Today, exactly one hundred years after its first formulation, this equivalence has been verified to be correct at least to an accuracy of 4 parts in 10 000 000 ! These measurements, at the Institut Laue-Langevin, Grenoble, and the Massachussets Institute of Technology (MIT), represent the most precise verification of the relation between mass and energy ever a
Risø National Laboratory, Technical University of Denmark, The Danish Meteorological Institute, Elsam and Energi E2 in Denmark have jointly developed a new method for predicting the energy produced by wind turbines. The method will save millions for electricity producers and consumers
In Denmark more than 5,000 wind turbines produce an average of more than 20 per cent of the Danish power consumption.
The electric utilities must supplement wind energy production with power fro
The European Commission, Directorate General for Education and Culture, congratulates Umeå University on the award of ICT-LEAP project, coordinated by Dr. Adi Anani. The project assists MEDA partners in accessing EU e-education technologies and opportunities.
The European Commission Head of Unit, Tempus – Erasmus Mundus, Mr. Augusto González, has warmly congratulated the successful application ICT-LEAP, Information and Communication Technologies Learning Pentagram. Apart from
Lein Applied Diagnostics Ltd, a Berkshire-based company that is developing a revolutionary new product to measure blood glucose levels in people with diabetes, has successfully completed clinical tests of its advanced prototypes and secured further investment from Seven Spires Investments, a member of Thames Valley Investment Network (TVIN). The funding will enable Lein to accelerate the development programme for its non-invasive optical instrument.
Diabetes is a major problem, with 1
Algorithms and programs being developed by scientists from the Moscow Physics Engineering Institute and the Keldysh Institute of Applied Mathematics RAS with the support of the International Science and Technology Centre will help oncologists to accurately and rapidly calculate an optimal dose of radiation. Then, they will be able to determine the direction and intensity of radioactive flows so as to have maximum harmful effect on the tumour with minimum irradiation of healthy tissue, and all
Researchers have discovered that your level of exposure to pollution can vary according to what method of transport you use, with travelling by taxis resulting in the highest levels of exposure and walking the least.
Research published in the journal Atmospheric Environment, describes how the team from Imperial College London and the Health and Safety Laboratory, Buxton, measured and visualised exposure to pollution levels, while using a variety of different transport methods
This Sunday morning (15th January) at 10.12 am GMT a capsule containing dust from Comet Wild 2 will return to Earth landing in the Utah Desert near Salt Lake City. The landing of the capsule marks the return of NASA’s Stardust mission which has been on a three billion-mile trip to collect pristine cometary material and interstellar dust. After their collection samples will be distributed to a limited number of specialist research teams. Four UK institutions have been invited to be part of the
Climate modelers at the Goddard Institute for Space Studies (GISS) have succeeded in reproducing the climate changes caused by a massive freshwater pulse into the North Atlantic that occurred at the beginning of the current warm period 8,000 years ago. Their work is the first to consistently model the event and the first time that the model results have been validated by comparison to the record of climate proxies that scientists regularly use to study the Earth’s past.

Discovery of memory mechanism provides clues to how humans learn speech
Researchers at Rutgers, The State University of New Jersey, believe they have located a place in the brain where songbirds store the memories of their parents’ songs. The discovery has implications for humans, because humans and songbirds are among the few animals that learn to vocalize by imitating their caregivers.
In a paper published today in the Proceedings of the National Academy of Sc
Workplace alcohol use and impairment directly affects an estimated 15 percent of the U.S. workforce, or 19.2 million workers, according to a recent study conducted at the University at Buffalo’s Research Institute on Addictions (RIA) and reported in the current issue of the Journal of Studies on Alcohol.
Information about workplace alcohol use and impairment during the previous 12 months was obtained by telephone interviews from 2,805 employed adults residing in the 48 con
A team of researchers, led by investigators at Washington University School of Medicine in St. Louis, has found that a gene variant for a bitter-taste receptor on the tongue is associated with an increased risk for alcohol dependence. The research team studied DNA samples from 262 families, all of which have at least three alcoholic individuals. The families are participating in a national study called the Collaborative Study of the Genetics of Alcoholism (COGA). COGA investigators report in the J
The thin, single-cell boundary where a tumor meets normal tissue is the most dangerous part of a cancer according to a new study by scientists at Washington University School of Medicine in St. Louis. The researchers found that tumor cells bordering normal tissue receive signals that tell them to wander away from the tumor, allowing the cancer cells to establish deadly metastatic tumors elsewhere in the body.
The researchers say their discovery demonstrates the importance of
