Neuroimaging study: Negative messages less effective on those who are substance dependent

A new neuroimaging study suggests that negative messages are not an effective way to deter drug and alcohol abuse, particularly among those who are substance-dependent. The study found that the brains of substance-dependent individuals show lower brain activity in response to negatively framed messages, leading to riskier decisions.

IU Kelley School study: CEO and chair roles shouldn't be split unless completely necessary

Researchers from the Indiana University Kelley School of Business found that companies should only separate CEO and chair roles when there is a performance problem. The 'demotion strategy', which keeps the CEO but brings in an independent chair, was found to be the most corrective approach, reversing prior year's performance by 150%.

New research presents most extensive pictures ever of an organism's DNA mutation processes

A team of researchers at Indiana University has discovered that spontaneous mutation rates in E. coli DNA are three times lower than previously thought. The study also found that mismatch repair proteins play a crucial role in maintaining the balance of guanine-cytosine and adenine-thymine content in the genome.

Middle-class children: Squeaky wheels in training

A study by Indiana University sociologist Jessica McCrory Calarco found that middle-class parents encourage their children to ask questions and seek help, while working-class parents coach them to avoid problems. This difference in parenting approaches can impact children's ability to interact with institutions later in life.

Foreclosure crisis and metropolitan crime rates

A recent study by Indiana University researchers found no association between housing-mortgage stress and crime rates in US metropolitan areas. Despite anecdotal evidence, the research indicates that higher levels of housing-mortgage stress do not correlate with violent or property crime rates.

Highways of the brain: High-cost and high-capacity

A new study proposes a communication routing strategy in the brain that mimics the American highway system, with select hubs forming the influential network known as the 'rich club'. This network provides quick and effective communication between billions of brain cells, with long-distance neural pathways favoring rich club connections.

Young people of multiple disadvantaged groups face worse health due to more discrimination

A study by Indiana University found that teens and young adults from multiple disadvantaged groups face more discrimination than their peers, resulting in poorer health outcomes. The research analyzed data from 1,052 participants and revealed a significant gap in health problems between those with and without multiple disadvantages.

IU bisexuality studies focus on health, behavior and identity

Researchers at Indiana University have conducted two studies on bisexual individuals, finding that women who identify as bisexual or lesbian report better health when their sexual identity matches their recent sexual history. In contrast, queer-identified women's mental, physical, and sexual well-being is not related to the gender of t...

Sloppy shipping of human retina leads IU researchers to discover new treatment path for eye disease

A serendipitous accident in shipping a donated human retina led to the discovery of a previously undetected mechanism causing choroidal neovascularization, a leading cause of vision loss. Researchers found that adhesion defects play a crucial role in maintaining the retina's structure and preventing blood vessel invasion.
