Parents don't fully understand biobank research, study finds
Researchers who collect genetic samples from children for medical research need to explain the process more clearly to parents, according to a new study that suggests many parents don't fully understand the finer details about how these samples will be used and stored. The study was published in June in Genetics in Medicine.

Adolescents are what they don't eat, too
Diets lacking omega-3 fatty acids -- found in foods like wild fish, eggs, and grass-fed livestock -- can have worsened effects over consecutive generations, especially affecting teens, according to a University of Pittsburgh study.

Premature aging of immune cells in joints of kids with chronic arthritis, Pitt team says
The joints of children with the most common form of chronic inflammatory arthritis contain immune cells that resemble those of 90-year-olds, according to a new study led by researchers at the Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine. The findings, published in the August issue of Arthritis and Rheumatism, suggest that innovative treatment approaches could aim to prevent premature aging of immune cells.

PTSD after traumatic events: Which teens are at risk?
With a large new study from Boston Children' Hospital, researchers identified risk factors for children exposed to trauma in developing PTSD from analyzing 6,483 teen–parent pairs from the National Comorbidity Survey Replication, a survey of the prevalence and correlates of mental disorders in the United States. 61 percent of the teens (ages 13 to 17) had been exposed to at least one potentially traumatic event in their lifetime. Nineteen percent had experienced three or more such events.

Cells move as concentration shifts
New research sheds new light on the physical mechanisms provoking the displacement of a sheet of cell, known as an epithelium. It covers our organs including the stomach and intestine, as well as our epidermis. In a paper about to appear in EPJ E, Martine Ben Amar from Pierre and Marie Curie University, Paris, explains the importance of understanding the displacement of the epithelium as a means of influencing the biological process involved in healing.

Essential clue to Huntington's disease solution found by McMaster researchers
Researchers at McMaster University have discovered a solution to a long-standing medical mystery in Huntington's disease. In this week's issue of the science journal, the Proceedings of the National Academy of Sciences, professor Ray Truant's laboratory at McMaster University's Department of Biochemistry and Biomedical Sciences of the Michael G. DeGroote School of Medicine reveal how they developed a way to measure the shape of the huntingtin protein, inside of cell, while still alive.

X chromosomes: Undoing a hairpin doubles gene activity
Male fruit flies have one X chromosome per cell, females have two. So genes on the male X must work twice as hard to produce the same amount of protein as its female counterparts. A team of researchers at Ludwig-Maximilians-Universitaet in Munich has found a new switch involved in making this possible.

NOAA-supported scientists find large Gulf dead zone, but smaller than predicted
NOAA-supported scientists found a large Gulf of Mexico oxygen-free or hypoxic 'dead' zone, but not as large as had been predicted. Measuring 5,840 square miles, an area the size of Connecticut, the 2013 Gulf dead zone indicates nutrients from the Mississippi River watershed, which drains 40 percent of the lower 48 states, are continuing to affect the nation's commercial and recreational marine resources in the Gulf.

Antimicrobial Agents and Chemotherapy
Antibiotic reduction campaigns do not necessarily reduce resistance
Antibiotic use -- and misuse -- is the main driver for selection of antibiotic resistant bacteria. This has led many countries to implement interventions designed to reduce overall antibiotic consumption. Now, using methicillin resistant Staphylococcus aureus as an example, Laura Temime of the Conservatoire National des Arts et Metiers, Paris, and collaborators warn that simply reducing antibiotics consumption does not necessarily reduce resistance. The research is published online ahead of print in Antimicrobial Agents and Chemotherapy.

Study shows job training results in competitive employment for youth with autism
A study shows intensive job training benefits youth with Autism Spectrum Disorders, one of the most challenging disabilities in the world where only 20 percent find employment. Published in the Journal of Autism and Developmental Disorders, the study demonstrates that nine months of intensive internship training, in conjunction with an engaged hospital, can lead to high levels of competitive employment in areas such as cardiac care, wellness, ambulatory surgery and pediatric intensive care units.

Video killed the interview star
A study from the DeGroote School of Business at McMaster University shows that using video conferencing for job interviews disadvantages both employers and candidates. In simulated job interviews, candidates who were interviewed by video-conferencing were rated lower by interviewers and were less likely to be recommended for hiring. Candidates also rated their interviewers as less attractive, personable, trustworthy and competent.

Human Mutation
Researchers identify genetic mutation linked to congenital heart disease
A mutation in a gene crucial to normal heart development could play a role in some types of congenital heart disease -- the most common birth defect in the US. The finding, from a team in The Research Institute at Nationwide Children's Hospital, could help narrow the search for genes that contribute to this defect, which affects as many as 40,000 newborns a year. The findings were published in a recent issue of in Human Mutation.
