Thirty percent of adults with Attention Deficit Disorder or Attention Deficit Hyperactivity Disorder (ADD/ADHD) report they were physically abused before they turned 18. This compares to seven per cent of those without ADD/ADHD who were physically abused before 18. The results were in a study published in this week's online Journal of Aggression, Maltreatment, and Trauma.

WASHINGTON, DC (March 6, 2014)— Drug companies spent $97.5 million marketing pharmaceuticals in the District of Columbia in 2012, with $30.5 million (31.3%) of that spending taking the form of payments and gifts to physicians, hospitals, and other healthcare providers, according to a report by researchers at the George Washington University School of Public Health and Health Services (SPHHS).

In 2011, one in three pregnant women in the U.S. delivered babies by cesarean delivery. While cesarean delivery may be life-saving for the mother, the baby or both, the rapid increase in cesarean birth rates since 1996 without clear indication raises concerns that this type of delivery may be overused.

For Chinese and Vietnamese immigrant parents and their children, success is equal to getting straight As, graduating from an elite university and pursuing an advanced degree. However, these narrow measures of success can make those who do not fulfil the strict aspirations feel like ethnic outliers, warn Jennifer Lee of UC Irvine in the US and Min Zhou of Nanyang Technological University in Singapore. Their findings are published in Springer's journal Race and Social Problems.

A visit to the dentist could one day require a detailed look at how genes in a patient's body are being switched on or off, as well as examining their pearly whites, according to researchers at the University of Adelaide.

A team of researchers from the RIKEN Center for Emergent Matter Science (CEMS) in Japan has identified unexpected dynamic properties of a type of light wave called evanescent waves. These surprising findings contrast sharply with previous knowledge about light and photons.

The study carried out in the Quantum Condensed Matter Research Group (CEMS, RIKEN, Japan) led by Dr. Franco Nori is published today in the journal Nature Communications.

Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells. This shuttling mechanism is crucial to maintain normal function of our genes and prevent disease. The results are published in the journal Nature Communications.

Interdisciplinary research team finds cellular high-speed shuttle

Iron deficiency predicts lower IQ scores and poor higher-order thinking skills in children adopted from institutional settings like orphanages, according to a new longitudinal study.

The study analyzed data on 55 children adopted from international institutions, with a focus on nutritional status. Conducted by researchers at the University of Minnesota, the research appears in the journal Child Development.

Cincinnati, Ohio – Obese adolescents not getting enough sleep? A study in today's The Journal of Pediatrics, shows they could be increasing their risk for developing diabetes, heart disease and stroke.

Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases in adults and young children.

However, the association is not as clear in adolescents, an age group known for lack of adequate sleep, and with an obesity and overweight prevalence of 30 percent in the United States.

In many primates, females mate with multiple partners, causing an often-intense competition amongst males to pass along their DNA to be king of the genome as well as the jungle.

To reconstruct phylogenetic trees from next-generation sequencing data using traditional methods requires a time-consuming combination of bioinformatic procedures including genome assembly, gene prediction, orthology identification and multiple alignment. As a consequence, more recently, scientists have relied on a simpler method where short sequence reads from each species are aligned directly to the genome sequence of a single reference sequence.

Working parents are often caught between the needs of their sick child and their job, which can lead to continued day care use even when their child is ill. New research has found children going to nursery when they are unwell with respiratory tract infections (RTIs) may be an important factor in the spread of these illnesses in the community.

The findings, to be presented today [Thursday 6 March] at the South West Society for Academic Primary Care (SW SPAC) meeting, explored why parents send their children to nursery when they are unwell.

Diets low in saturated fat don't curb heart disease risk or help you live longer, says a leading US cardiovascular research scientist and doctor of pharmacy in an editorial in the open access journal Open Heart.

And current dietary advice to replace saturated fats with carbohydrates or omega 6-rich polyunsaturated fats is based on flawed and incomplete data from the 1950s, argues Dr James DiNicolantonio.

Dietary guidelines should be urgently reviewed and the vilification of saturated fats stopped to save lives, he insists.

EVANSTON, Ill. --- Women's reproductive health may never be the same, thanks to Northwestern University biomedical engineer Patrick Kiser and his first-of-its-kind intravaginal ring that reliably delivers an antiretroviral drug and a contraceptive for months.

Kiser's one ring delivers two drugs that do three important things: the device is designed to protect against HIV and herpes as well as unwanted pregnancy. It will be the first device with the potential to offer this protection to be tested in women.

Human activity influences ocean beach bacterial communities, and bacterial diversity may indicate greater ecological health and resiliency to sewage contamination, according to results published March 5, 2014, in the open access journal PLOS ONE by Elizabeth Halliday from Woods Hole Oceanographic Institution and colleagues.
