Gray Matter Volume in Brain Region Can Predict Risk Tolerance
Using whole-brain analysis, scientists discovered that the gray matter volume of a region in the right posterior parietal cortex of the brain was significantly predictive of individual risk attitudes. Men and women with higher grey matter volume in this region exhibited less risk aversion. The findings may clarify why risk tolerance decreases with age. More...09 Oct 2014
PET-CT Used for Lung Cancer Diagnosis May Be Less Effective in Areas Where Infectious Lung Disease Is More Common
An analysis of data gleaned from 70 studies revealed that use of the diagnostic imaging modality fluorodeoxyglucose F18-positron emission tomography combined with CT may not effectively differentiate benign disease from lung cancer in patients with endemic infectious lung disease compared with nonendemic regions, according to recent research.

fMRI Neuro Scans Reveal Gray Matter Disparities in Media Devices Multitaskers
By simultaneously using laptops, cell phones, and other media devices, people could be changing their brain structure. A study reveals that individuals who frequently use several media devices used concurrently have lower gray-matter density in one specific region of the brain compared to those who use just one device occasionally.

Oncologists Recommend Less Radiation for Elderly Women with Early Breast Cancer
In a healthcare environment where the costs of patient treatment are increasingly considered against possible benefit, a new study has found that US radiation oncologists are using fewer or less-aggressive radiation procedures on older women with early-stage breast cancer. More...07 Oct 2014
