The American Society for Microbiology (ASM) and the Foundation for Innovative New Diagnostics (FIND) have signed a Memorandum of Understanding confirming their agreement to work in partnership for projects aimed at strengthening infectious disease diagnosis and service integration in resource-poor and transitional countries.

National guidelines need to be developed and implemented to ensure an adequate uptake of interventions known to reduce the risk of perinatal HIV transmission, according to a research paper published in the latest issue of Medical Journal of Australia. About 10 per cent of people living with HIV infection in Australia are women, many of whom are in their reproductive years.

The first population-based study of pelvic pain in Australia has found that general practitioners need to be aware of the high prevalence of chronic pelvic pain (CPP) in women and be ready to discuss the issue with patients, particularly in relation to underlying issues of anxiety and depression.

A multicenter U.S. registry study examining the treatment of Barrett's esophagus (BE) with high-grade dysplasia (HGD) showed that in 92 patients treated with endoscopic circumferential ablation who had at least one follow-up biopsy session, 90.2 percent were free of HGD at an average of one-year follow-up. This registry is the first to report on the use of circumferential ablation for BE HGD.

A team of researchers from the Harvard Stem Cell Institute (HSCI) and Columbia University, in a collaboration catalyzed by the Project A.L.S./Jenifer Estess Laboratory for Stem Cell Research, has demonstrated that pluripotent stem cells generated from a patient with ALS (amyotrophic lateral sclerosis) can be directed to differentiate into motor neurons - the very brain cells destroyed by ALS.

Cells rely on calcium as a universal means of communication. For example, a sudden rush of calcium can trigger nerve cells to convey thoughts in the brain or cause a heart cell to beat. A longstanding mystery has been how cells and molecules manage to appropriately sense and respond to the variety of calcium fluctuations within cells.

In a breakthrough discovery, Dr. Kevin Eggan, Chief Scientific Officer of The New York Stem Cell Foundation and Principal Faculty Member of the Harvard Stem Cell Institute, has produced human stem cell lines from the cells of patients afflicted with a version of amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease.

It's not just bomb-sniffing dogs; animals everywhere rely on their sense of smell. Now, Howard Hughes Medical Institute and Rockefeller University researchers show just how important olfaction is, proving that fruit flies with a normal sense of smell have a survival advantage over those that don't.

It turns out that an old dog - or at least an old fruit-fly cell - can learn new tricks. Researchers at the Stanford University School of Medicine have found that mature, specialized cells naturally regress to serve as a kind of de facto stem cell during the fruit-fly life cycle.

A Group Health study in the August 2 issue of The Lancet adds fuel to the growing controversy over how well the flu vaccine protects the elderly. The study of more than 3,500 Group Health patients aged over 65 found no link between flu vaccination and risk of pneumonia during three flu seasons.

The new high-accuracy terrestrial localisation systems are suitable for applications as diverse as tracking workers in emergency situations to following cyclists racing around a track.

The Health Professions Council has launched its consultation on the revised standards of education and training (SETs) and revised standards of education and training guidance. The standards of education and training are the standards against which the HPC assesses education and training programmes.

A ground breaking technique has visually shown the development of hips in fetuses for the very first time. Tissue from the hips of spontaneously aborted fetuses ranging from 8 weeks of gestation to full term were dyed and studied in both natural light and polarised light microscopy.

According to researchers at the University at Buffalo's Research Institute on Addictions (RIA), the odds of 18-19 year old college women experiencing sexual aggression are 19 times greater when they binge drink than when they don't drink. Binge drinking or heavy drinking was defined as drinking four or more drinks on a drinking occasion.

Extreme heat or cold is not only uncomfortable, it can be deadly - causing proteins to unravel and malfunction. For many years now, scientists have understood the molecular mechanisms that enable animals to sense dangerous temperatures; such as extremely high temperatures that directly trigger heat sensor proteins known as TRP channels.

As the world's leaders and AIDS community gather in Mexico for the biennial global conference on HIV and AIDS, UNITAID, UNICEF and the World Health Organization (WHO) announced an infusion of $50 million aimed at halting mother-to-child transmission of HIV.

From nursery rhymes to Shakespearian sonnets, alliterations have always been an important aspect of poetry whether as an interesting aesthetic touch or just as something fun to read. But a recent study suggests that this literary technique is useful not only for poetry but also for memory. In several experiments, researchers R. Brooke Lea of Macalester College, David N.
