The findings show that healthy test subjects respond less accurately when information is shown only to the right brain.
A recent analysis of Japan fisheries data reveals that most fish caught off the northeast coast remain below seafood consumption limits, despite tightened regulations. However, highly contaminated demersal fish consistently show high levels of cesium contamination from the damaged nuclear power plant.
Entomologists at UC Riverside reconstructed the evolutionary history of assassin bugs using molecular, paleontological, behavioral, and ecological data. The new phylogeny reveals that kissing bugs originated around 27-32 million years ago, contradicting previous estimates, and suggests a single origin or two separate but close origins.
The implementation of a 24-h ICU in-house staff intensivist coverage significantly improved mortality rates and reduced hospital length of stay by nearly half a day. This model also led to quicker decision-making and a positive trend in end-of-life care quality.

Ischemic stroke risk after acute myocardial infarction (AMI) dropped significantly, from 4.7% in 1998-2000 to 3.8% in 2007-2008, due to improved AMI care. Reperfusion therapy, blood clot dissolving therapy, and statins were found to be independent predictors of reduced stroke risk.
Researchers found that both high and low mating rates are detrimental to female sea slug fitness, suggesting indirect benefits to traumatic mating. The study suggests that there may be additional fitness benefits beyond reproduction.
Married men tend to consume fewer drinks than single, divorced, or widowed men due to their wives' lower levels of drinking. In contrast, long-term married women often consume more drinks than recently divorced or widowed women, who may experience increased drinking after a divorce.
A recent Texas A&M University study reveals that hurricanes can intensify by 50% faster when passing over large areas of fresh water, making them more devastating. The research analyzed Tropical Cyclones for the decade 1998-2007 and found a significant correlation between freshwater regions and increased storm intensity.

A study using data from over 1 million adults found that a newer risk prediction equation classified more individuals as having chronic kidney disease and accurately predicted death and end-stage renal disease. The CKD-EPI equation outperformed the MDRD Study equation in categorizing risk, especially at higher GFR levels.
A recent study in PLOS Medicine challenges the widely-held view that foreign aid for health displaces government funds in recipient countries. Experts Rajaie Batniji and Eran Bendavid re-analysed data to find no straightforward negative relationship between government spending on health and foreign aid for health.
A new study by the University of California Santa Barbara found that female brown-headed cowbirds prefer less intense wing-spreading displays as courtship behavior. This suggests that current physical condition may not be the most reliable measure of male quality for females to use when choosing a mate.
