While walking is one of the healthiest and most popular exercises, it also results in more trips to the emergency room for women than any other non-equipment exercise, a University of Arkansas study revealed.
The study, conducted by associate health science professors Ches Jones and Lori Turner, has been accepted for publication in the summer 2005 issue of the “Journal of Women and Aging.” Jones presented the results at the 7th World Conference on Injury Prevention and Safety Promotion held
A paper published this week in the journal Science supports the hypothesis that heat transfer by ocean currents – rather than global heating or cooling – may have been responsible for the global temperature patterns associated with the abrupt climate changes seen in the North Atlantic during the past 80,000 years.
Authored by the University of Bremen’s Frank Lamy and colleagues, the paper provides new evidence that Southern Hemisphere climate may not have changed in step with Northern Hem
When a fly drops in to sample your picnic lunch, it’s basically tasting the same thing you taste, according to a new study by University of California, Berkeley, scientists.
In the first detailed genetic study of fly taste receptors, UC Berkeley neuroscientist Kristin Scott and her colleagues showed that fruit flies have receptors devoted to sweet and bitter tastes just like humans. While human taste receptors are limited to the tongue, the receptors in flies are mounted on bristles sc
Type 2 diabetics who take two drugs in combination with insulin can effectively regulate their blood-sugar levels without the common side effect of weight gain, according to a new study by researchers at UT Southwestern Medical Center at Dallas. Their findings appear in the July issue of Diabetes Care. It’s the first study to analyze the safety and effectiveness of triple therapy using insulin, metformin and a drug in the thiazolidinedione family.

Physicians may be able to make early decisions on the best treatment for breast cancer, thanks to research published in Breast Cancer Research today. A gene involved in the adhesion of cells is less active in breast tumors with a poor prognosis than those that are less aggressive, researchers found.Measuring the activity of the ALCAM gene in primary breast tumors could give physicians advanced warning about the likely clinical outcome of the disease. This should help them decide whether to prescribe
The oily stains accompanying the yellowish rings on the leaves and pods of bean plants are some of the symptoms of the disease known as “Halo blight” – highly important in temperate zones like Spain. The seeds are one of the most important sources of transmission of the pathogen, which means the detection of this bacterium in seeds is one of the most efficient control methods. Nevertheless, agricultural engineer Arantza Rico Martínez has shown, in her PhD thesis, that this blight pathogen cannot be
Three-dimensional ecography is a novel advance in the application of ultrasounds in the diagnosis of a number of pathologies. It involves a system of probes that register images in multiple layers. Then the information is transferred to a computer within the ecograph itself, where the three-dimensional reconstruction is carried out automatically. Advances in information technology have so perfected the data processing that this reconstruction can be obtained in real time.
This new diagnostic
Nature magazine has published an article by Xabier Irigoien, a researcher at AZTI, the Basque Fisheries and Marine Technological Research Centre. The article provides data on the diversity of marine life at the bottom of the sea – particularly amongst algae.
Species diversity
Most research carried out on the diversity of species has been with land animals. According to these investigations, diversity is greater in life-forms with medium productivity – defined as th
New research from the University of North Carolina at Chapel Hill indicates that treatment with anabolic steroids may improve surgical repair of massive or recurrent tears of the shoulder’s rotator cuff tendons. Such injuries extend well beyond the world of high-performance athletes, professional and collegiate – often occurring among older weekend athletes, including tennis and golf players. The study, which appears in the June issue of the American Journal of Sports Medicine, was led by Dr. Spero
Middle-aged and older Americans with heart disease who cut back on their prescribed medications because of cost were 50% more likely to suffer heart attacks, strokes, or angina than those who did not report cost-related medication underuse, according to a new study funded in part by the National Institute on Aging, part of the National Institutes of Health. Michele Heisler, M.D., M.P.A., at the Veterans Affairs Ann Arbor Healthcare System, Ann Arbor, MI, and colleagues* conducted the study, which
A new generation of gamma cameras is on the horizon, thanks to a collaboration between the BioImaging Unit of the Space Research Centre at the University of Leicester, the Institute for Cancer Research at the Royal Marsden Hospital (Surrey) and medical physicists at the Leicester Royal Infirmary.
Dr John Lees, who leads the BioImaging Unit, is developing the new camera using funding from the University’s seedcorn fund, Lachesis. It will be a small, affordable hand-held device, producing hi
Researchers at the Universitat Jaume I in Castellón, Spain, and McGill University in Montreal have found a relationship between the increased heartbeat some people experience after drinking a certain amount of alcohol and the risk of developing a personality that is sensitive to rewards and, hence, to addictions.
The study, which was published in the March edition of the journal Alcoholism: Clinical and Experimental Research, concludes that people who experience an increase in their heart rate a
Footballers could benefit from a new hi-tech shirt that alerts managers to players’ heart rate and hydration levels.
The shirt, which has in-built pulse and sweat monitors was designed by Northumbria University student David Evans.It uses ECG sensors to record the electrical activity of the heart and send signals to a computer on the team bench, alerting managers, coaches and physios to the player’s heart rate and highlighting any abnormal rhythms.

UK scientists are warning that world chocolate production could fall dramatically if diseases, which have devastated South American cultivation of cacao over the past 15 years (the raw material used for producing chocolate), were to spread to some of the world’s other cacao producing regions.
Writing in the Summer 2004 edition of Biologist, Dr Gareth Griffith of the University of Wales, Aberystwyth warns that increased trade and improved transport links between South America and other caca
The International Society for Reef Studies has launched an ambitious programme to communicate the results of scientific research in order to improve policies and practices impacting on coral reef conservation around the world. The ISRS was founded in 1980 by international marine scientists to promote the production and dissemination of scientific knowledge on coral reefs, both living and fossil.
To help build more effective management policies for the world’s endangered reef ecosystems, ISRS s
Results of a UK study in this week’s issue of THE LANCET highlight how the treatment of cytomegalovirus infection remains a priority in order to improve the prognosis for people with HIV-1 infection, including people already receiving antiretroviral therapy.
The advent of highly active antiretroviral therapy (HAART) at the end of the 20th century dramatically improved treatment for people with HIV-1 infection. Before HAART, cytomegalovirus (CMV) was a major cause of opportunistic infection in HIV
