A loss of salt and body fluid can stimulate kidney regeneration and repair in mice, according to a new study. This innate regenerative response relies on a small population of kidney cells in a region known as the macula densa (MD), which senses salt and exerts control over filtration, hormone secretion, and other key functions of this vital organ.

Researchers have developed a python-tooth-inspired device as a supplement to current rotator cuff suture repair, and found that it nearly doubled repair strength. Their biomimetic approach following the design of python teeth helps to reattach tendons to bone more securely. The device not only augments the strength of the repair but can also be customized to the patient.
