Innovation could bring flexible solar cells, transistors, displays

Tweet

WEST LAFAYETTE, Ind. – Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing.

Mosquito behavior may be immune response, not parasite manipulation

Tweet

Malaria-carrying mosquitos appear to be manipulated by the parasites they carry, but this manipulation may simply be part of the mosquitos' immune response, according to Penn State entomologists.

Penn study shows how immune system peacefully co-exists with 'good' bacteria

Tweet

PHILADELPHIA - The human gut is loaded with commensal bacteria – "good" microbes that, among other functions, help the body digest food. The gastrointestinal tract contains literally trillions of such cells, and yet the immune system seemingly turns a blind eye. However, in several chronic human diseases such as inflammatory bowel disease (IBD), HIV/AIDS, cancer, cardiovascular disease, and diabetes, the immune system attacks these normally beneficial bacteria, resulting in chronic inflammation and contributing to disease progression.

OSA is associated with less visceral fat accumulation in women than men

Tweet

ATS 2013, PHILADELPHIA ─ A new study from researchers in Japan indicates that obstructive sleep apnea (OSA) is independently associated with visceral (abdominal) fat accumulation only in men, perhaps explaining gender differences in the impact of OSA on cardiovascular disease and mortality.

Enzyme-activating antibodies revealed as marker for most severe form of rheumatoid arthritis

Tweet

In a series of lab experiments designed to unravel the workings of a key enzyme widely considered a possible trigger of rheumatoid arthritis, researchers at Johns Hopkins have found that in the most severe cases of the disease, the immune system makes a unique subset of antibodies that have a disease-promoting role.

Children of married parents less likely to be obese

Tweet

Children living in households where the parents are married are less likely to be obese, according to new research from Rice University and the University of Houston.

"Childhood obesity is a significant public health issue in our country, with nearly one-third of all U.S. children ages 2-17 overweight or obese," said Rachel Kimbro, study co-author, associate professor of sociology at Rice and director of Rice's Kinder Institute Urban Health Program. "Despite this, very little research has been conducted to explore the impact of family structure on this epidemic."

Alleviating hunger in the US -- researcher says, it's a SNAP

Tweet

URBANA - A University of Illinois researcher says that the cornerstone of our efforts to alleviate food insecurity should be to encourage more people to participate in the Supplemental Nutrition Assistance Program (SNAP) "because it works."

Survey points out deficiencies in addictions training for medical residents

Tweet

A 2012 survey of internal medicine residents at Massachusetts General Hospital (MGH) – one of the nation's leading teaching hospitals – found that more than half rated the training they had received in addiction and other substance use disorders as fair or poor. Significant numbers felt unprepared to diagnose or treat such disorders, results similar to surveys of practicing physicians. In response to the findings, recently published online in the journal Substance Abuse, the MGH has increased residents' training in addiction medicine.

Mega genomes of spruce species decoded

Tweet

Canadian and Swedish scientists today released genome sequences of two of the most economically important forest trees in the world.

Conifers supply raw materials for the Canadian forestry industry, which accounted for $23.7 billion in Canada's economy in 2011. Gross output of the forest sector in Sweden in 2009 was $29.7 billion.

NIH researchers conduct first genomic survey of human skin fungal diversity

Tweet

While humans have harnessed the power of yeast to ferment bread and beer, the function of yeast or other types of fungi that live in and on the human body is not well understood. In the first study of human fungal skin diversity, National Institutes of Health researchers sequenced the DNA of fungi at skin sites of healthy adults to define the normal populations across the skin and to provide a framework for investigating fungal skin conditions.
