Forensic anthropology researchers at North Carolina State University have developed a technique that can provide an approximate age for juveniles and young people based on an X-ray of the frontal sinus region of the skull. The technique can be used to help identify human remains in forensic cases, as well as to determine age ranges in archaeological research or for living people for whom no records are available.

Animal Findings Suggest That Gender May Also Influence Chemical Exposure Risks for Humans
COLUMBIA, Mo. — Parents, teachers and psychologists know boys and girls behave differently. However, that difference isn’t taken into account by most methods used to assess the risk to children from chemical exposure, according to Cheryl Rosenfeld, associate professor of biomedical sciences in the University of Missouri’s Bond Life Sciences Center. A series of experiments by Rosenfeld studied the effects of prenatal exposure to bisphenol A (BPA) on later reproductive-associated behaviors using a socially and genetically monogamous rodent, the California mouse, which may better mirror most human societies than other rodents.

Researchers at Yale University have developed a new way of seeing inside solid objects, including animal bones and tissues, potentially opening a vast array of dense materials to a new type of detailed internal inspection.
The technique, a novel kind of magnetic resonance imaging (MRI), creates three-dimensional images of hard and soft solids based on signals emitted by their phosphorus content. (more…)
