WASHINGTON -- While the U.S. Department of Veterans Affairs (VA) provides mental health care of comparable or superior quality to care provided in private and non-VA public sectors, accessibility and quality of services vary across the VA health system, leaving a substantial unmet need for mental health services among veterans of the recent wars in Afghanistan and Iraq, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.

January 30, 2018 - The risks of penile reconstruction surgery (phalloplasty) appear higher in female-to-male transgender (transmale) patients undergoing gender confirmation surgery, compared to native male (cismale) patients undergoing phalloplasty for other reasons, reports a study in the February issue of Plastic and Reconstructive Surgery®, the offici

(PHILADELPHIA and NEW ORLEANS) - Medical students who spend more time engaging in the arts may also be bolstering the qualities that improve their bedside manner with patients, according to new research from Tulane and Thomas Jefferson universities.

Male rats exposed to air blasts designed to mimic those from explosives used in recent military conflicts have symptoms of post-traumatic stress disorder (PTSD) that are improved by a drug currently being evaluated in humans for treatment-resistant depression and suicidal tendencies. The research, published in eNeuro, provides a new direction for addressing the mental health problems that often arise following a common brain injury in veterans.

People on welfare can earn more money in their jobs -- and potentially leave the program -- if the trauma they've faced since childhood is addressed, Drexel University research shows.

Think of it this way: If you were constantly being given job training but couldn't stay employed or make enough money to get by, you'd probably feel pretty badly about yourself.

Large-scale particle physics laboratories around the world have huge accelerators with a circumference of up to 27 km, as in the case of CERN (Conseil Européen pour la Recherche Nucléaire). Tremendously costly experiments to study the creation and annihilation of matter are conducted in these accelerators. Would it be possible to simulate these collisions in small experiments on a table top?

Humans change entire landscapes - by building cities and roads, by farming land and by exploiting natural resources. What effects does this have on animals and their habitats? Using the GPS location data of more than 800 animals, a team of scientists was able to prove a reduction in animal movements in areas with a high human footprint. Movements of mammals in areas with a high human footprint were found to be on average one half to one third the extent of their movements in areas with a low human footprint.

Scientists from Siberian Federal University (SFU) and the L. V. Kirensky Institute of Physics (SB RAS) conducted theoretical studies of hybrid Tamm plasmons. Using numerical calculations, they were able to predict the structure in which it is possible to control the wavelength of these quasiparticles by means of an external electric field or heating. The study is presented in the Journal of the Optical Society of America B.

Some fads never die. Low-carb diets were a thing in the late 90s and they're still a thing now. But why does this fad have staying power? Is it because the touted benefits are real? Or is that greasy, low-carb burger fried in snake oil?

Learn about ketogenic diets in this video from Reactions, a video series produced by the American Chemical Society and PBS Digital Studios.

CHAMPAIGN, Ill. -- Third-graders who spend a class session in a natural outdoor setting are more engaged and less distracted in their regular classroom afterward than when they remain indoors, scientists found in a new study.

This effect, reported in the journal Frontiers in Psychology, was large and occurred week after week, regardless of teacher expectations.
