Dietary calcium is better than supplements at protecting bone health

Women who get most of their daily calcium from food have healthier bones than women whose calcium comes mainly from supplemental tablets, say researchers at the School of Medicine. Surprisingly, this is true even though the supplement takers have higher average calcium intake.

Sunlight exposure may help prevent periodontal disease

Sunlight promotes healthy teeth.As the days get shorter and colder, it gets harder to spend time in the sun, and that’s probably bad for your teeth. According to an article in the Journal of Periodontology from WUSM researcher Charles F. Hildebolt, our teeth may be light-sensitive, at least indirectly. Vitamin D, which regulates calcium absorption, is produced by the body when exposed to sunlight.

Nervous system ‘ears’ line up across from ‘mouths’

Neurons communicate at a synapseAs the nervous system develops early in life, it must create millions of synapses—small spaces between nerve cells across which the cells can communicate. Scientists have long speculated that these synapses are deliberately organized to place the structures that send messages on one cell directly across from the structures on another nearby nerve cell that receive those messages. School of Medicine researchers have provided the first experimental proof of this theory at the level of the nervous systems’ most fundamental unit: individual clusters of structures that send and receive signals.
