New analysis techniques of bone tissue have been developed at Rensselaer Polytechnic Institute.
What I gather of this technique, because it is a bit complex, is that researches can get information for tiny tiny pieces of bone samples. Which as you can imagine gives a whole new insight into research and "the fight against osteoporosis" (source) . Not to mention how it can help archeology!
"We're able to take very small, nanoscale-sized bone samples, and determine the protein signatures of the bone," said Deepak Vashishth, head of the Department of Biomedical Engineering at Rensselaer, who led the study. "This is a relatively quick, easy way for us to determine the history of the bone – how and when it formed – as well as the quality of the bone, and its likelihood to fracture."
