In an editorial published in the April 19 issue of the Annals of Internal Medicine, Indiana University School of Medicine gastroenterologist Thomas Imperiale, M.D., says virtual colonoscopy may become one of the most valuable assessment tools available for colorectal cancer screening.
“I expect a lot from a screening test — zero risk, high sensitivity, high specificity, reasonable ease and convenience, and cost effectiveness,” said Dr. Imperiale, who is professor of medicine and Re
New state of matter more remarkable than predicted — raising many new questions
The four detector groups conducting research at the Relativistic Heavy Ion Collider (RHIC) — a giant atom “smasher” located at the U.S. Department of Energy’s Brookhaven National Laboratory — say they’ve created a new state of hot, dense matter out of the quarks and gluons that are the basic particles of atomic nuclei, but it is a state quite different and even more remarkable than had been predi
Attacking novel S1P target eliminates cancerous tumors in some cases
An antibody developed by San Diego-based Lpath Therapeutics, Inc. could someday treat many of the deadliest solid and liquid tumors. This unique monoclonal antibody, called SphingomabTM, was tested in several animal models of human cancer and was shown to significantly retard cancer growth on a consistent basis; in some cases, it eliminated the tumor altogether.
According to Roger Sabbadini, Founder an
Experts to debate themes in new book from UN University

Please use the contacts listed below or email terrycollins@rogers.com and/or mwangi@intech.unu.edu to schedule a time. A panel presentation and book launch will take place on Tuesday 19 April at the UN Secretariat Building, Con
Use of such cholesterol-lowering drugs as statins may reduce the risk of advanced prostate cancer, according to research that followed 34,428 U.S. men for more than a decade.
The study, presented at the 96th Annual Meeting of the American Association for Cancer Research, found that men who used these medications had half the risk of advanced prostate cancer and a third of the risk of metastatic or fatal prostate cancer, compared to men who did not use cholesterol-lowering drugs. R
In mouse models of intestinal cancer, use of an anti-inflammatory drug eliminated all of the cancer-causing risks produced by a high-fat Western-style diet – even when several genetic brakes to cancer formation were missing in the animals, say researchers from the Albert Einstein Cancer Center.
The investigators, who presented their findings at the 96th Annual Meeting of the American Association for Cancer Research, say that while the results do not yet have relevance for preventi
Long term use of calcium supplements provides a protective effect that lasts for years against development of potentially precancerous colon polyps, researchers at Dartmouth Medical School say.
Their study, presented at the 96th Annual Meeting of the American Association for Cancer Research, found that patients in the treatment group of a randomized trial of calcium supplements had a 36 percent reduction in polyp formation in the five years after the end of the trial, compared t
Imagine a computer system that can automatically search through videos of football matches and pull out all the shots on goal or all the fouls.
Creating the elements that make such a system possible is a key result from the IST BUSMAN project. The current generation of computer systems is excellent at searching for and manipulating text: as the spectacular success of Google has shown. However, computers are now routinely used to store and process more than just text – videos of
Climate change is widely attributed to the build-up of greenhouse gases, such as carbon dioxide, in the Earth’s atmosphere. However, scientists from the School of Engineering Sciences at the University of Southampton have shown that the impact of carbon dioxide is being felt in space too.
Dr Hugh Lewis from the School will present a paper to the Fourth European Conference on Space Debris at the European Space Operations Centre (ESOC) in Germany this week indicating that inc
Children say the funniest things, but what makes them laugh? Do German and Israeli kids share the same sense of humour – or is the Simpsons the universal language of laughter?
That is the puzzle that a University of Ulster researcher is hoping to unravel as part of a five-nation probe into what makes children laugh.
Professor Máire Messenger-Davies, who is based at the University’s Coleraine campus, will join researchers from Germany, Israel, South Africa and the US in th
Recent financial results by major players in the UK grocery industry seem to point to the ever-increasing consolidation of grocery retailing on the UK High Street, but is this actually in the consumer’s interest, and is it what the consumer really wants? Dr Alan Hallsworth of the University of Surrey School of Management has been looking at trends in UK grocery retailing in the UK for over 25 years and comments, ‘ consumers display ambivalent attitudes towards retail change. There is a residual
A new study from the University of Glasgow that analyses information from over 2000 11 year old children and their parents (in 1984-5) reveals no evidence that number of parents in the household or family meals are associated with children’s diets, while maternal employment is associated with better diets.
The children involved in the study were part of the Medical Research Council’s West of Scotland 11 to 16 Study, a study of health and lifestyles, which has followed them since a
Maps of Antarctica need to be amended. The long-awaited collision between the vast B-15A iceberg and the landfast Drygalski ice tongue has taken place. This Envisat radar image shows the ice tongue – large and permanent enough to feature in Antarctic atlases – has come off worst.
An image acquired by Envisat on 15 April 2005 shows that a five-kilometre-long section at the seaward end of Drygalski has broken off following a collision with the drifting B-15A. The iceberg itself appear
Can be of use in the treatment of diabetes patients with insulin resistance
Type 2 diabetes is a clinical disease characterised by disruption to the metabolism of glucose and lipids as well as to the production of and physiological reactions to insulin. These disruptions are partly due to a reduced absorption of glucose in the cells that form the body’s fat and muscle tissue. Now scientists at Karolinska Institutet have established that a type of drug targeted at receptors in t
Monash University researchers and staff of the Melbourne-based biotechnology company Cerylid Biosciences Ltd, have discovered and developed a new class of anti-clotting drugs that appears to be more effective than aspirin at preventing disease-causing blood clots and has fewer side effects.
Heart attack and stroke are the leading cause of death and disability in the western world and result in the death of about 50,000 Australians each year.

Ocean warming has a negative impact on the condition of elephant seals, reveals a study published in the Open Access journal BMC Biology. High ocean temperatures observed from 1975 to the late 1990s are correlated with a 28% decrease in the weight of elephant seal pups. Elephant seals are shown to be sensitive to ocean temperature changes associated with both long-term 25-year cycles and short-term 3-4 year cycles such as those caused by El Niño. Sea lions and fur seals that feed
