Memory loss from West Nile virus may be preventable, study finds

Over 10,000 people in the U.S. are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. A new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. When the inflammation was reduced by treatment with an arthritis drug, the animals' ability to learn and remember remained sharp after West Nile disease.

Degree of Uncertainty Associated with the Diagnosis, Doctors Recommend

According to new research published in the International Journal for Quality in Health Care, the parents of paediatric patients might react more negatively to doctors who communicate uncertainty of diagnosis explicitly, such as directly stating they are unsure, as compared to doctors who use implicit language, such as discussing most likely diagnosis or providing several possible diagnoses under consideration.

Skin Pigmentation Are Simple; Study Suggests

Researchers from the Broad Institute of MIT and Harvard, Stanford University, and Stony Brook University, they described that the study suggests that the genetics of skin pigmentation are simple. A small number of known genes, it is thought, However, these studies rely on datasets consisting almost entirely of information from northern Eurasian populations–those that reside mostly in higher latitude regions. This study has been published in Cell.
 

Specially timed signals ease tinnitus symptoms

According to the study, a team from the University of Michigan reports the results of the first animal tests and clinical trial of the approach, including data from 20 human tinnitus patients. Millions of Americans hear ringing in their ears, a condition called tinnitus.

As the new study shows an experimental device could help quiet the phantom sounds by targeting unruly nerve activity in the brain. Results of the first animal tests and clinical trial of the approach resulted in a decrease in tinnitus loudness and improvement in tinnitus-related quality of life. This study got published in Science Translational Medicine.

Scarce Metals Could Be Replaced By Carbon Nanomaterials

The new study at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene. Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. This study is published in the Journal of Cleaner Production.
