Asymptomatic atherosclerosis linked to cognitive impairment
In a study of nearly 2,000 adults, researchers found that a buildup of plaque in the body's major arteries was associated with mild cognitive impairment.

New device may ease mammography discomfort
Researchers have developed a new device that may result in more comfortable mammography for women. According to a new study, standardizing the pressure applied in mammography would reduce pain associated with breast compression without sacrificing image quality.

Obstructive sleep apnea treatments may reduce depressive symptoms
Treatment for obstructive sleep apnea with continuous positive airway pressure or mandibular advancement devices can lead to modest improvements in depressive symptoms, according to a study published by Marcus Povitz, Carmelle Bolo, and colleagues from University of Calgary, Canada, in this week's PLOS Medicine.

Circumstances are right for weed invasion to escalate, researchers say
What some farmers grow as pasture plants others view as weeds. But with the need to cheaply feed food animals rising, circumstances are right for the weed invasion to escalate, says Jacob Barney, an assistant professor in the College of Agriculture and Life Sciences and a Fralin Life Science Institute affiliate.

Johns Hopkins scientists link gene to tamoxifen-resistant breast cancers
After mining the genetic records of thousands of breast cancer patients, researchers from the Johns Hopkins Kimmel Cancer Center have identified a gene whose presence may explain why some breast cancers are resistant to tamoxifen, a widely used hormone treatment generally used after surgery, radiation and other chemotherapy.

Study finds way to conserve soil and water in world's driest wheat region
In the world's driest rainfed wheat region, Washington State University researchers have identified summer fallow management practices that can make all the difference for farmers, water and soil conservation, and air quality. Wheat growers in the Horse Heaven Hills of south-central Washington farm with an average of 6-8 inches of rain a year. Wind erosion has caused blowing dust that exceeded federal air quality standards 20 times in the past 10 years.

CT scans of coral skeletons reveal ocean acidity increases reef erosion
For coral reefs to persist, rates of reef construction must exceed reef breakdown. Prior research has largely focused on the negative impacts of ocean acidification on reef growth, but new research this week from scientists at the Hawai'i Institute of Marine Biology, based at the University of Hawai'i - Mānoa, demonstrates that lower ocean pH also enhances reef breakdown: a double-whammy for coral reefs in a changing climate.

Boy moms more social in chimpanzees
Four decades of chimpanzee observations reveals the mothers of sons are 25 percent more social than the mothers of daughters, spending about two hours more per day with other chimpanzees than the girl moms did. Researchers from Duke and George Washington University believe mothers are giving young males the opportunity to observe males in social situations to help them develop the social skills they'll need to thrive in adult male competition.

Biology trumps chemistry in open ocean
Scientists laid out a new framework based on in situ observations that will allow them to describe and understand how phytoplankton assimilate limited concentrations of phosphorus, a key nutrient, in the ocean in ways that better reflect what is actually occurring in the marine environment. This is important because nutrient uptake is a property of ocean biogeochemistry, and in many regions controls carbon dioxide fixation, which ultimately can play a role in mitigating climate change.

Grasshoppers signal slow recovery of post-agricultural woodlands, study finds
By comparing grasshoppers found at woodland sites once used for agriculture to similar sites never disturbed by farming, UW-Madison researchers Philip Hahn and John Orrock show that despite decades of recovery, the numbers and types of species found in each differ, as do the understory plants and other ecological variables, like soil properties.

How does the brain react to virtual reality? Study by UCLA neuroscientists provides answer
UCLA neurophysicists studying a key brain region where Alzheimer's disease begins have discovered how the brain processes virtual reality. 'The pattern of activity in a brain region involved in spatial learning in the virtual world is completely different than in the real world,' said Mayank Mehta, a UCLA professor of physics, neurology, and neurobiology and senior author. 'We should be cautious before proceeding rapidly with millions of people using virtual reality.'

Unmanned underwater vehicle provides first 3-D images of underside of Antarctic sea ice
A National Science Foundation-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice. SeaBED, as the vehicle is known, measured and mapped the underside of sea-ice floes in three areas off the Antarctic Peninsula that were previously inaccessible.

Muscle relaxant may be viable treatment for rare form of diabetes
A commonly prescribed muscle relaxant may be an effective treatment for a rare but devastating form of diabetes, researchers at Washington University School of Medicine in St. Louis report. The drug, dantrolene, prevents the destruction of insulin-producing beta cells in animal models of Wolfram syndrome and in cells taken from patients who have the illness.
