Diet, microbiota, and microbial metabolites in colon cancer risk in rural Africans and African Americans

submitted by: sjokeefe
Background: Epidemiologic studies have suggested that most cases of sporadic colon cancer can be attributed to diet. The recognition that colonic microbiota have a major influence on colonic health suggests that they might mediate colonic carcinogenesis. Objective: To examine the hypothesis that the influence of diet on colon cancer risk is mediated by the microbiota through their metabolites, we measured differences in colonic microbes and their metabolites in African Americans with a...

Our Built Environment: It Takes Energy

submitted by: nsf

Can we rethink the way buildings use energy? John Ochsendorf, an Associate Professor of Civil and Environmental Engineering and Architecture at MIT, is working with his students to change the way buildings are made and how they consume energy.

Nanotechnology: AFM and SEM Imaging of Titanium Dioxide Nanoparticles

submitted by: cranberrylab

This video was made by students in the CHE230X/ME230X: Nanobiotechnology Laboratory Experience course at Worcester Polytechnic Institute. In this video, students demonstrate AFM and SEM imaging of titanium-dioxide-coated surfaces. This work was funded by the National Science Foundation (EEC 0941746).

LIGHT absolutely does NOT exist.
