Coffee Suppresses Gut Microbiome, Improves Ability of Intestine to Contract: Study

New experiments, performed in vitro on bacterial cultures and in vivo in rats, show that coffee — regardless of caffeine content — inhibits gut microbiota and stimulates intestinal smooth muscle contractility. Hegde et al, feeding rats coffee and also mixing it with gut bacteria in Petri dishes, found that coffee suppressed bacteria and increased muscle motility.

This image of the irregular galaxy NGC 4485 was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). NGC 4485 has been involved in a dramatic gravitational interplay with its larger galactic neighbor, NGC 4490, out of frame to the bottom right in this image. This ruined the original, ordered spiral structure of the galaxy and transformed it into an irregular one. Below NGC 4485 one can see a bright, orange background galaxy: CXOU J123033.6+414057. This galaxy is the source of X-ray radiation studied by NASA’s Chandra X-ray Observatory. It’s distance from Earth is about 850 million light-years. Image credit: NASA / ESA / Hubble.

TiO2 triggers biofilm formation by commensal bacteria: (A, B) the clustering effect of TiO2 on (A) E. coli and (B) E. faecalis in vitro was visualized by Nanolive imaging in the presence of 0, 0.5, 1, or 50 μg/ml TiO2 after 24 h incubation. False-coloring was applied to images based on refractive index, where black represents the refractive index of TiO2 and green represents bacteria.
