Modern city dwellers have lost about half their gut microbes
Deep in the human gut, myriad "good" bacteria and other microbes help us digest our food, as well as keep us healthy by affecting our immune, metabolic, and nervous systems. Some of these humble microbial assistants have been in our guts since before humans became human-certain gut microbes are found in almost all primates, suggesting they first colonized a common ancestor.

MIT engineers develop stickers that can see inside the body
Ultrasound imaging is a safe and noninvasive window into the body's workings, providing clinicians with live images of a patient's internal organs. To capture these images, trained technicians manipulate ultrasound wands and probes to direct sound waves into the body. These waves reflect back out to produce high-resolution images of a patient's heart, lungs, and other deep organs.
