Purdue study finds dairy better for bones than calcium carbonate

WEST LAFAYETTE, Ind. - A Purdue University study shows dairy has an advantage over calcium carbonate in promoting bone growth and strength. Connie Weaver, distinguished professor and head of the food and nutrition department, found that the bones of rats fed nonfat dry milk were longer, wider, m...

Building better bones and tissue in the lab

Tissue engineering holds great promise for the treatment of conditions such as arthritis, osteoporosis, fibrosis, periodontal disease and traumatic injuries. However, bone and cartilage currently produced in the laboratory don't have sufficient strength to function in the body so they're not clin...

Bare bones of crystal growth: Biomolecules enhance metal contents in calcite

Blacksburg, Va. From shells to bones, the skeletons of organisms contain small amounts of impurity elements such as magnesium. Because the levels of these elements provide important clues to past environments, a considerable effort has focused on understanding how to relate impurity contents to t...

Where and why humans made skates out of animal bones

Archaeological evidence shows that bone skates (skates made of animal bones) are the oldest human powered means of transport, dating back to 3000 BC. Why people started skating on ice and where is not as clear, since ancient remains were found in several locations spread across Central and North E...

Fused nasal bones helped tyrannosaurids dismember prey

New evidence may help explain the brute strength of the tyrannosaurid, says a University of Alberta researcher whose finding demonstrates how a fused nasal bone helped turn the animal into a "zoological superweapon."

Tiny bones rewrite textbooks

Small but remarkable fossils found in New Zealand will prompt a major rewrite of prehistory textbooks, showing for the first time that the so-called "land of birds" was once home to mammals as well. The tiny fossilised bones - part of a jaw and a leg - belonged to a unique, mouse-sized land anima...

Orange, grapefruit juice for breakfast builds bones in rats

It may sound like Saturday cartoons: a strong-boned rat that can't be broken. But a couple of Texas researchers say the real hero is citrus juice. Orange and grapefruit juice regularly given to lab rats prevented osteoporosis, long considered an unavoidable aging disease in which bones become mor...
