Rolling Stone’s retraction of an incendiary article about an alleged gang rape on the campus of the University of Virginia certainly deserves a place in the pantheon of legendary journalism screw-ups. It is highly unusual – although not unprecedented – for a news organization to air its dirty laundry so publicly.

African-American women who live in rural areas have lower rates of major depressive disorder (MDD) and mood disorder compared with their urban counterparts, while rural non-Hispanic European-American women have higher rates for both than their urban counterparts, according to a new study.

Major depressive disorder is a debilitating mental illness and the prevalence of depression among both African- and Rural-Americans is understudied, according to background in the study. Addie Weaver, Ph.D., of the University of Michigan, Ann Arbor, and coauthors examined the interaction of Urban-American vs.Rural-American residence and race/ethnicity on lifetime and 12-month MDD and mood disorder in African-American and non-Hispanic European-American women.

Melanoma is the leading cause of skin cancer¬related deaths and surgical excision is the primary therapy for melanoma. It is recommended that melanomas should be excised within 4 to 6 weeks of the diagnostic biopsy because surgical delay may result in the potential for increased illness and death from other malignant neoplasms, along with anxiety and stress. 

In a study that included more than 32,000 cases of melanoma among Medicare patients, approximately 20 percent experienced a delay of surgery that was longer than 1.5 months, and about 8 percent of patients waited longer than 3 months for surgery.

Gene variations that could mean yield increases, drought tolerance and aflatoxin resistance will boost productivity in the years to come.

A study included the growing years of 2011, a drought year, and 2012, on dryland and irrigated corn in College Station and in Mississippi, all with similar results, said Dr. Seth Murray, an AgriLife Research corn breeder in the soil and crop science department of Texas A&M University at College Station. 

Genetic studies in humans, zebrafish and mice have revealed that two different types of genetic variations team up to cause a rare condition called Hirschsprung's disease, flaws in early nerve development that lead to poor colon function which must often be surgically corrected.

About one in every 5,000 babies is born with Hirschsprung's disease, which causes bowel obstruction and can be fatal if not treated. The disease arises early in development when nerves that should control the colon fail to grow properly. Those nerves are part of the enteric nervous system, which is separate from the central nervous system that enables our brains to sense the world.

It’s not often that medievalists get as excited as they have been over the revival of a medieval remedy for eye conditions involving garlic, onions, wine and ox gall, prepared in a bronze vessel. The concoction, mixed up by a team from Nottingham University, appeared to show promising results in the battle against MRSA. It didn’t kill it all, but it apparently killed 90%. This has revived enthusiasm for trawling ancient texts for the solutions to modern problems.

Testosterone replacement therapies are controversial in males so extending it to females will likely be even more so. But research involving mice suggests an association between low levels of androgens (which includes testosterone) and atherosclerosis and obesity in females. 

A new species of bird called Llallawavis scagliai (Scaglia's Magnificent Bird) is shedding light on the diversity of the group and how these giant extinct predators interacted with their environment.

The new species found in South America is the most complete terror bird ever discovered, with more than 90% of the skeleton exquisitely preserved and also reveals details of anatomy that rarely preserve in the fossil record, including the auditory region of the skull, voice box, complete trachea, bones for focusing the eye, and the complete palate, allowing an unprecedented understanding of the sensory capabilities of these extinct predatory birds.

A new paper provides evidence of a new mastrevirus, tentatively named switchgrass mosaic-associated virus 1 (SgMaV-1). Other members of the mastrevirus genus, a group of DNA viruses, are known to be responsible for decimating yields in staple food crops (including corn, wheat and sugarcane) throughout Africa, Europe, Asia and Australia.

It has never been reported in North America.

The switchgrass exhibited mosaic symptoms--splotchy, discolored leaves--characteristic of a viral infection, yet tested negative for known infections. Deep sequencing, a new technology, revealed the plants were infected with a new virus in the genus mastrevirus, the first of its kind found in North America.

A lower percentage of children are eating "fast food" on any given day, and calories consumed by children from those types of burger, pizza and chicken restaurants also dropped, according to a new study.
