Osteochondral allograft transplantation effective for treating knee cartilage injuries Posted: 10 Jul 2016 06:40 AM PDT For athletes and highly active patients who sustain cartilage injuries to their knee, an osteochondral allograft transplantation can be a successful treatment option, according to new research. The study showed these patients were consistently able to return to sport or recreational activities after the surgery, though frequently at a lower activity level.

Concussions on the rise for adolescents Posted: 10 Jul 2016 06:40 AM PDT Sustaining a concussion during adolescence may be more common than previous estimates, according to researchers.

Ecological context of mosquito-borne infectious disease Posted: 08 Jul 2016 11:51 AM PDT The resurgence of Zika virus has raised anxieties about the spread of infectious disease by mosquitoes; climate change and species invasions are strong themes on the minds of infectious disease experts.

Ultrashort cell-free DNA reveals health of organ transplants Posted: 08 Jul 2016 11:51 AM PDT When cells die, whether through apoptosis or necrosis, the DNA and other molecules found in those cells don't just disappear. They wind up in the blood stream, where degraded bits and pieces can be extracted. This cell-free DNA (cfDNA) is degraded due to its exposure to enzymes in the blood but is nonetheless a powerful monitoring tool in cancer, pregnancy and organ transplantation. Now, borrowing a genomics technique used in the study of the ancient past, a graduate student has come up with a diagnostic tool that can open a window into a transplant recipient's immediate future through the analysis of cfDNA.

Scientists link bipolar disorder to unexpected brain region Posted: 08 Jul 2016 11:49 AM PDT For the first time, researchers show that ensembles of genes within the striatum could be deeply involved in bipolar disorder. Most modern studies of bipolar disorder have concentrated on the brain's cortex, the largest part of the brain in humans, associated with higher-level thought and action.

Dam good! Beavers may restore imperiled streams, fish populations Posted: 08 Jul 2016 11:49 AM PDT Using a first-of-its-kind, watershed-scale experiment, researchers demonstrate beaver dam analogs in the Bridge Creek Watershed of north central Oregon's John Day Basin foster natural beaver activity, which benefits the area's threatened steelhead trout population.

Traffic noise increases the risk of heart attack Posted: 08 Jul 2016 11:49 AM PDT Your risk of heart attack increases with the amount of traffic noise to which you are exposed. The increase in risk -- though slight -- is greatest with road and rail traffic noise, less with aircraft noise.

Massive open-access database on human cultures created Posted: 08 Jul 2016 11:49 AM PDT D-PLACE is an open-access database that brings together a dispersed body of information on the language, geography, culture and environment of more than 1,400 human societies. It comprises information mainly on pre-industrial societies that were described by ethnographers in the 19th and early 20th centuries. It enables researchers to investigate how patterns in cultural diversity are shaped by different forces, including shared history, demographics, migration, cultural innovations, and environmental and ecological conditions

Researchers show phone calls can forecast dengue fever outbreaks Posted: 08 Jul 2016 11:49 AM PDT A team of scientists has developed a system that can forecast the outbreak of dengue fever by simply analyzing the calling behavior of citizens to a public-health hotline. This telephone-based disease surveillance system can forecast two to three weeks ahead of time, and with intra-city granularity, the outbreak of dengue fever, a mosquito-borne virus that infects up to 400,000 people each year.

Economics study finds volume discounts don't increase profitability for video game Posted: 08 Jul 2016 09:36 AM PDT Discounts tied to buying large quantities of virtual goods have little impact on profitability and do not increase the number of customers making purchases, A study by economists finds.
