Concrete for taller wind turbine towers passes tests, could help expand wind energy nationwide

A research team led by Iowa State's Sri Sritharan has just finished an 18-month, $1 million study of concrete technology for taller wind turbine towers. Sritharan said lab tests demonstrate the technology will work. Economic studies also say the technology can be cost competitive. Sritharan said the taller towers could enable wind energy production in all 50 states.

Emotional toll from mass trauma can disrupt children’s sense of competence

Traumatic events, such as a terrorist attack or natural disaster, can have a profound effect on children's perceptions of competence – or how they view their ability to control a situation. Children with higher levels of competence were overall more resilient and had fewer PTSD symptoms, according to a new study by an Iowa State University professor.

Family history of Alzheimer’s may alter metabolic gene that increases risk for disease

A new Iowa State University study may have identified the link that explains years of conflicting research over a mitochondrial gene and the risk for Alzheimer’s disease. Researchers found a dramatic difference in the gene’s impact on memory, general cognitive function and risk based on a family history of Alzheimer’s disease and the length of a specific section of the gene.

After receiving bad advice, bullying victims say they would give same bad advice to others

Targets of workplace bullying get plenty of advice from coworkers and family on how to respond to the situation and make it stop. While well intentioned, much of the advice victims receive is impractical or only makes their situation worse. Despite the bad advice, most victims said they would tell others in their situation to do the same thing.
