(Baltimore, MD) – A new study published today in the journal Pediatrics (Epub ahead of print) found that nearly half of children with autism spectrum disorders (ASD) are reported to wander or "bolt," and more than half of these children go missing. Led by researchers from the Interactive Autism Network (IAN), the nation's largest online autism research initiative and a project of the Kennedy Krieger Institute, this study provides the most comprehensive estimate of elopement occurrence in a United States community-based sample of more than 1,200 children with ASD.

ANN ARBOR, Mich.—A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.

Once believed to merely store and relay genetic information, RNA is now known to be a cellular Swiss Army knife of sorts, performing a wide variety of tasks and morphing into myriad shapes.

ANN ARBOR, Mich. — A new approach to lung scanning could improve the diagnosis and treatment of a lung disease that affects approximately 24 million Americans and is the country's third-highest cause of death.

Researchers at the RIKEN Center for Genomic Medicine (CGM) and their colleagues have identified 8 new loci associated with susceptibility to atopic dermatitis in the Japanese population. The findings, which appear in the journal Nature Genetics, advance our understanding of the genetic basis of the skin disorder, which affects millions of children and adults around the world.

Researchers headed by Erwin Wagner, the Director of the BBVA Foundation-CNIO Cancer Cell Biology Programme at the Spanish National Cancer Research Centre (CNIO), have deciphered how a stress-inducible gene regulator, AP-1, controls the survival of liver tumor-initiating cells. These results, published in the online edition of Nature Cell Biology, could provide new preventive strategies and identify potentially targetable molecules to prevent liver cancer.

Public health 'superheroes' are needed to help tackle the growing challenges posed by obesity, alcohol, smoking and other public health threats, according to new research published today.

The research, an international collaboration from the Universities of Leeds, Alberta and Wisconsin, calls for government and policy makers to recognise the role that public health leaders can play in addressing these significant health challenges.

(Boston) – Boston University School of Medicine (BUSM) investigators have led the first genome-wide evaluation of genetic variants associated with Parkinson's disease (PD). The study, which is published online in PLOS ONE, points to the involvement of specific genes and alterations in their expression as influencing the risk for developing PD.

Jeanne Latourelle, DSc, assistant professor of neurology at BUSM, served as the study's lead author and Richard H. Myers, PhD, professor of neurology at BUSM, served as the study's principal investigator and senior author.

The increase in anal cancer incidence in the U.S. between 1980 and 2005 was greatly influenced by HIV infections in males, but not females, according to a study published October 5 in the Journal of the National Cancer Institute.

The HIV protease inhibitor, Nelfinavir, can be used to treat HER2-positive breast cancer in the same capacity and dosage regimen that it is used to treat HIV, according to a study published October 5 in the Journal of the National Cancer Institute.

Methadone reduces the risk of HIV transmission in people who inject drugs (PWID), as reported by an international team of researchers in a paper published today in the online edition of the British Medical Journal. This team included Dr. Julie Bruneau from the CHUM Research Centre (CRCHUM) and the Department of Family Medicine at the Université de Montréal.

Prescription drugs that today help patients fight severe fungal infections might tomorrow be even more effective, thanks to unexpected findings from agriculture-based, food-safety-focused studies by U.S. Department of Agriculture (USDA) scientists and their colleagues.

CHICAGO (October 5, 2012) – Researchers from East Carolina University used a new technique of genotyping to identify the source of a hematology clinic outbreak of Mycobacterium mucogenicum, a gram-positive, acid-fast bacteria found in tap water. This is the first outbreak of M. mucogenicum in an ambulatory care setting; five other outbreaks have been reported in hospital settings since 1995. The study was published in the November issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

The results from comparative analysis of this population demonstrate the risk of developing dementia increased by 50% for subjects who consumed benzodiazepines during the follow-up period, compared with those who had never used benzodiazepines. Although this study does not confirm a cause and effect relationship, as is the case for all epidemiological research, the researchers recommend increased vigilance when using these molecules, which remain useful in the treatment of insomnia and anxiety in elderly patients.

These proteins are required for melanocyte stem cell self-maintenance and, as such, correct pigmentation throughout the mice's life span. Without these two proteins, the mice's fur turns white.Their research is published in the review 'Cell Report' and paves the way for serious possibilities in terms of stopping the formation of melanomas, tumours that originate from melanocyte cells.
