A team of researchers from the Massachusetts Institute of Technology (MIT) in Cambridge, MA have demonstrated a novel automated fabrication process consisting of a three-step sol-gel extrusion, structure freezing and drying, and mechanical drawing process which results in production of highly aligned polymer films. Alignment of molecular chains within polymers is a desirable trait for many applications as it results in superior mechanical and thermal properties in the polymeric materials.

Too many stroke patients in Canada are not getting the rehabilitation they need to return to a healthy, active life, according to a new study which will be presented at the Canadian Stroke Congress in Vancouver tomorrow.
Previous research has suggested that gout might be associated with diabetes, but the findings were restricted to one study of men at high risk of heart disease and stroke. The researchers wanted to know if the link existed in the general population, and also applied to women.
They searched the Health Improvement Network (THIN), an electronic database of the anonymised health records of almost 7.5 million patients registered with 477 general practices across the UK.
Washington, DC (October 2, 2014) — Two blood markers are strongly linked with the development of heart failure in individuals with mild to severe kidney disease, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Elevations in these markers may indicate subclinical cardiovascular changes that subsequently contribute to the development of heart failure.
Washington, DC (October 2, 2014) — Aerobic physical activity is strongly linked with better health-related quality of life, fewer depressive symptoms, and prolonged life in kidney failure patients on dialysis. The findings, which come from a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN), suggest that dialysis facilities have an opportunity to improve patients' health by providing exercise programs.
A "mini-stroke" may increase your risk of developing post-traumatic stress disorder (PTSD), according to new research in the American Heart Association journal Stroke.
Transient ischemic attack (TIA), like stroke, is caused by restricted blood supply to the brain. A TIA is temporary and often lasts less than five minutes, without causing permanent brain damage.
"We found one in three TIA patients develop PTSD," said Kathrin Utz, Ph.D., a study author and post-doctoral researcher in the Department of Neurology at the University of Erlangen-Nuremberg in Germany.
Bottom Line: The effectiveness of a treatment to reduce blood clots among otolaryngology patients admitted for surgery appears to differ based on patient risk and the procedure.

Wild cheetah populations have declined precipitously in the past century: from an estimated 100,000 in 1900 to only around 10,000 today. A new study from researchers in Europe, South Africa and at North Carolina State University suggests that the energy cheetahs spend looking for prey, rather than their high-speed hunting tactics or food stolen by other predators, may be to blame for their dwindling numbers.
PROVIDENCE, R.I. [Brown University] — Among the negative feelings that can plague a teen's psyche is a perception of "invalidation," or a lack of acceptance. A new study by Brown University and Butler Hospital researchers suggests that independent of other known risk factors, measuring teens' sense of invalidation by family members or peers can help predict whether they will try to harm themselves or even attempt suicide.
WASHINGTON -- A new report from the National Research Council recommends best practices that law enforcement agencies and courts should follow to improve the likelihood that eyewitness identifications used in criminal cases will be accurate. Science has provided an increasingly clear picture of the inherent limits in human visual perception and memory that can lead to errors, as well as the ways unintentional cues during law enforcement processes can compromise eyewitness identifications, the report says.
COLUMBUS, Ohio – When people are in a bad mood, they are more likely to actively search social networking sites like Facebook to find friends who are doing even worse than they are, a new study suggests.
Researchers found that, in general, people use social media to connect with people who are posting positive and success-oriented updates.
Bethesda, MD (Oct. 2, 2014) — Nonsteroidal anti-inflammatory drugs (NSAIDs) — such as ibuprofen and aspirin — increase one's risk of upper gastrointestinal bleeding. When taken in combination with other drugs, this risk is significantly higher, according to new research appearing in the October issue of Gastroenterology, the official journal of the American Gastroenterological Association.
For decades, research has generally focused on individual, family and peer factors to explain illicit drug use, neglecting neighborhood factors as a cause. While the scant previous research on neighborhood factors and illicit drug use has focused on facets such as crime and socio-demographic characteristics, none has explored the associations between the perceived frequency of drug sales, drug use, and peer attitudes towards drug use. Now a study out of New York University's Center for Drug Use and HIV Research (CDUHR), address this paucity in the research.
A unique collection of studies exploring the theme of the Third Global Symposium on Health Systems Research has been published today in a supplement to Health Policy and Planning.
For older adults, being unable to identify scents is a strong predictor of death within five years, according to a study published October 1, 2014, in the journal PLOS ONE. Thirty-nine percent of study subjects who failed a simple smelling test died during that period, compared to 19 percent of those with moderate smell loss and just 10 percent of those with a healthy sense of smell.
