The five most-read posts on Scope this week were:
Careful, your comfy chair might be making you soft: An article published in the journal Science suggests that textures, shapes, weights and temperatures-physical cues associated with touch-influence thoughts, behavior and judgments.
Bioengineers make cancer detector from digital camera: In the spirit of do-it-yourselfer Mark Frauenfelder, Rice University bioengineers have jury-rigged a cancer-detection device from a $400 digital camera and a bundle of fiber-optic cables.
Using unconventional therapies to troubleshoot the brain: Brain scientists, including a team at Stanford, are employing a wide range of approaches to diagnose and treat neurological conditions such as depression, Parkinson's disease and Alzheimer's.
Stanford scientists identify a melanoma-initiating cell: Researchers at Stanford have identified something that looks suspiciously like a cancer stem cell in melanoma. Post-doctoral fellow Alexander Boiko, PhD, says that the finding may explain why current immunotherapies against the disease are largely unsuccessful.
A new target-heart-rate formula for women, by women: A Northwestern University cardiologist has generated a new formula for estimating the peak heart rate a woman should attain during exercise: 206 minus 88 percent of age. Under the old formula, based on studies of men and used for almost four decades, that number was figured to be 220 minus age.
