Diet for your DNA: Novel nutrition plan sparks debate around data protection

Personalized nutrition based on an individual’s genotype – nutrigenomics – could have a major impact on reducing lifestyle-linked diseases such as obesity, heart disease and Type II diabetes, experts say. However, a study of more than 9,000 volunteers reveals that strict regulations need to be put in place before nutrigenomics becomes publicly acceptable due to people’s fears around personal data protection. —> Read More Here

Understanding drinking behaviors among women with unwanted pregnancies

Most women reduce or stop drinking alcohol upon discovery of pregnancy. A new study looks at changes in alcohol use, and factors contributing to these changes, among women with unwanted pregnancies. Findings indicate that most women with unwanted pregnancies quit or reduce alcohol consumption once they discover their pregnancies, and that some may be substituting alcohol for drugs once they discover their pregnancies. —> Read More Here

Bar attendance supports heavy drinking by young adults in the US-Mexico border region

Mexico is a nearby destination where younger US residents can legally drink heavily. However, high levels of drinking on the US side are not always linked to recent travel to Mexico. New findings show that higher levels of drinking among US-Mexico border youth are closely linked to their patterns of bar attendance, but not to how they think about drinking. —> Read More Here

Smoking interferes with neurocognitive recovery during abstinence from alcohol

Researchers know that alcohol-dependent individuals (ALC) sustain neurocognitive impairment even after detoxification. A new study examines specific domains of cognitive recovery in conjunction with smoking status. Findings show that smoking status influenced the rate and level of neurocognitive recovery during eight months of abstinence in the ALC group. —> Read More Here

Competition keeps health-care costs low, U.S. researchers find

Medical practices in less competitive health-care markets charge more for services, according to a study. The study, based on U.S. health-care data from 2010, provides important new information about the effects of competition on prices for office visits paid by preferred provider organizations, known more commonly as PPOs. PPOs are the most common type of health insurance plan held by privately insured people in the United States. —> Read More Here

Special microscope captures defects in nanotubes

Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. Carbon nanotubes have been touted as exceptional materials with unique properties that allow for extremely efficient charge and energy transport, with the potential to open the way for new, more efficient types of electronic and photovoltaic devices. However, these traps, or defects, in ultra-thin nanotubes can compromise their effectiveness. —> Read More Here
