Where you receive medical care impacts many things - including whether or not you receive inappropriate medical tests, according to a new study.

Researchers from NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center, in a new retrospective study publishing online March 12th in JAMA Oncology, conclude that patients with low-risk prostate or breast cancer were more likely to receive inappropriate imaging during treatment, based on the region of the country in which they received medical care.

oday marked the publication of the first ever genome-wide association study of rosacea, a common and incurable skin disorder. Led by Dr. Anne Lynn S. Chang of Stanford University's School of Medicine, and co-authored by 23andMe, the study is the first to identify genetic factors for this condition.

The human eye is optimized to have good color vision at day and high sensitivity at night. 

But until recently it seemed as if the cells in the retina were wired the wrong way round, with light traveling through a mass of neurons before it reaches the light-detecting rod and cone cells.

New research presented at a meeting of the American Physical Society has uncovered a remarkable vision-enhancing function for this puzzling structure.

Where is the line between advocating science and protecting corporate profits? It's usually only clear to people trying to show the other side is involved in wrongdoing. A paper in PLOS Medicine uses sugar industry documents to note how they influenced research priorities for the 1971 US National Caries Program (NCP).

When it comes to buying things, our brains can't see the big, black-and-white forest for all the tiny, colorful trees, according to marketing scholars at The Ohio State University, who say that people who were shown product images in color were more likely to focus on small product details--even superfluous ones--instead of practical concerns such as cost and functionality.

The findings in the Journal of Consumer Research mesh well with science, they believe, namely in how vision evolved in the brain, and suggest that viewing objects in black and white helps our brains focus on what's most important. The researchers recruited people through Amazon Mechanical Turk, a service that provides online study participants for fee, so caveat emptor on the results.

Studying the intricate fractal patterns on the surface of cells could give researchers a new insight into the physical nature of cancer, and provide new ways of preventing the disease from developing.

This is according to scientists in the US who have, for the first time, shown how physical fractal patterns emerge on the surface of human cancer cells at a specific point of progression towards cancer.

Publishing their results today, 11 March, in the Institute of Physics and Germany Physical Society's New Journal of Physics, they found that the distinctive repeating fractal patterns develop at the precise point in which precancerous cells transform into cancer cells, and that fractal patterns are not present either before or after this point.
