Global regulator for DNA trade needed

Amid growing concern that synthetic life sciences pose biosecurity and biosafety risks, scrutiny is increasing into the burgeoning DNA sequence trade. Research published today in the Bulletin of the Atomic Scientists, published by SAGE, looks at the necessity of a global regulator for DNA trade, and the significant barriers to creating one.

New genetic analysis technique isolates culprit gene in families with inherited single-gene kidney diseases

A University of Michigan-led research team has identified a gene responsible in some families for a devastating inherited kidney disorder, thanks to a new, faster method of genetic analysis not available even two years ago. The success offers hope that scientists can speed the painstaking search for the genes responsible for many rare diseases and test drugs to treat them.

Simian immunodeficiency virus is at least 32,000 to 75,000 years old

An ancestor of HIV that infects monkeys is thousands of years older than previously thought, suggesting that HIV, which causes AIDS, is not likely to stop killing humans anytime soon, finds a study by University of Arizona and Tulane University researchers.

Research on signaling pathways may help to design therapy for neurodevelopmental disorders

Researchers at the Center for Neuroscience Research at Children's National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development-the epidermal growth factor receptor pathway and the Notch pathway-operate together to determine how many and which types of brain cells are created during growth and repair in developing and adult brains.

Researchers decode key DNA in evolution of aging, development and fertility

UC Irvine researchers have deciphered how lowly fruit flies bred to rapidly develop and reproduce actually evolve over time. The findings, reported in the Sept. 15 online issue of Nature, contradict the long-held belief that sexual beings evolve the same way simpler organisms do and could fundamentally alter the direction of genetic research for new pharmaceuticals and other products.

Researchers discover chronic stress accelerates breast cancer progression

Chronic stress acts as a sort of fertilizer that feeds breast cancer progression, significantly accelerating the spread of disease in animal models, researchers at UCLA's Jonsson Comprehensive Cancer Center have found.

Researchers to contribute to brain circuit mapping in Human Connectome Project

Thirty-three researchers at nine institutions will contribute to the Human Connectome Project (http://www.humanconnectome.org/consortia). Using powerful, custom-built brain scanners, a supercomputer, new brain analysis techniques and other state-of-the-art resources, they will trace the anatomical 'wires' that interconnect thousands of different regions of the human brain's gray matter.

Recommendations for developing novel therapies for hypertrophic cardiomyopathy

An abrupt, fatal heart attack in a young athlete on the playing field is a tragedy destined to repeat itself over and over until more is understood about hypertrophic cardiomyopathy (HCM), a genetic disorder that is the most common cause of sudden death in young people but which affects people of all ages.

Researchers to conduct gene analysis for ankylosing spondylitis

A new study designed to test suspected links between genes and two immune disorders could open the door to better ways to diagnose and treat the conditions that affect a combined total of approximately 2.5 million people in the United States, report scientists at The University of Texas Health Science Center at Houston (UTHealth).

Researchers identify mechanism to reduce pathogenic effect of bacillus bacteria

A European-Asian collaboration of scientists, notably including CNRS, the Institut Pasteur in Paris, the Institut Pasteur Korea in Seoul (IP Korea/Equipe Avenir Inserm and the Université de Toulouse have identified ten virulence genes of the tubercle bacillus. The inactivation of these genes lessens the pathogenic effects of the bacillus.

Scientists discover 13 genes linked to human body mass

Johns Hopkins scientists who specialize in unconventional hunts for genetic information outside nuclear DNA sequences have bagged a weighty quarry 13 genes linked to human body mass. The experiments screened the so called epigenome for key information that cells remember other than the DNA code itself and may have serious implications for preventing and treating obesity, the investigators say.

Researchers find clue behind ASD affecting males than females

New research from the Centre for Addiction and Mental Health (CAMH) and The Hospital for Sick Children (SickKids), both in Toronto, Canada provides further clues as to why Autism Spectrum Disorder (ASD) affects four times more males than females. The scientists discovered that males who carry specific alterations of DNA on the sole X-chromosome they carry are at high risk of developing ASD. The research is published in the September 15 issue of Science Translational Medicine.

Researchers find association between physical fitness and children’s brain development

Researchers have found an association between physical fitness and the brain in 9- and 10-year-old children: Those who are more fit tend to have a bigger hippocampus and perform better on a test of memory than their less-fit peers.

Johns Hopkins offers sources who can answer queries on prostrate cancer

September 19-25 is National Prostate Cancer Awareness Week. If you are planning a story on prostate cancer, a disease that's diagnosed in more than 200,000 American men each year, please consider calling on experts from the Johns Hopkins Brady Urological Institute.

Researchers develop ChIP Enrichment Analysis to identify drug targets, biomarkers

Researchers from Mount Sinai School of Medicine have developed a new computational method that will help streamline the analysis of gene expression experiments and provide scientists with a better mechanistic understanding of the differences between diseased and normal cells. The new database and software, called ChIP Enrichment Analysis (ChEA), will revolutionize how researchers identify drug targets and biomarkers.

Calm men preferred by women: Study

According to a new study, women prefer calm men to stressed ones. Researchers at the University of Abertay Dundee in Scotland found that women were more attracted to calm, collected men with lower levels of the stress hormone cortisol coursing through their systems, than men who are chronically stressed. The study was published in the Proceedings of the Royal Society B journal. The researchers also found that there was no clear association between attractiveness and high levels of testosterone as was thought before.
