A research team has observed that exposure to warmer ambient temperatures increases bone strength and prevents the loss of bone density. Find out what gives our bones their remarkable ability to heal breaks in a finely tuned process that involves stem cells, cartilage, and bone. Z-scores can be used to compare a measurement to a reference value. The BHOF notes that Z-scores can be misleading because older adults commonly have low bone density. The early bone density machines in the 1970's and early 1980's all used different kinds of units, so results were reported in Z-scores to allow comparisons to normal people. Compared to most mammal bones, bird bones have more empty space inside and bat bones are thinner, but the bone material for both animals is actually denser than the bones of a similar-sized rodent.
