A forensic science study sheds light on how the bones of infants and juveniles decay. The findings will help forensic scientists determine how long a young person’s remains were at a particular location, as well as which bones are best suited for collecting tissue samples to help ID the deceased.
Self-powered implantable device stimulates fast bone healing, then disappears without a trace
Researchers know that electricity can help speed up bone healing, but “zapping” fractures has never really caught on, since it requires surgically implanting and removing electrodes powered by an external source. Xudong Wang’s latest invention may make electrostimulation a much more convenient option to speed up bone healing.
Corals Carefully Organize Proteins to Form Rock-Hard Skeletons
Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the Journal of the Royal Society Interface, shows for the first time that several proteins are organized spatially – a process that’s critical to forming a rock-hard coral skeleton.
Radiocarbon dating and CT scans reveal Bronze Age tradition of keeping human remains
Using radiocarbon dating and CT scanning to study ancient bones, researchers have uncovered for the first time a Bronze Age tradition of retaining and curating human remains as relics over several generations.
Acid Reflux Drugs Linked to Increased Fracture Risk in Kids
Proton pump inhibitors – a widely used class of drugs used to treat acid reflux and related symptoms – may lead to an increased risk of fractures in children and adolescents, reports a study in the Journal of Pediatric Gastroenterology and Nutrition (JPGN). Official journal of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition, JPGN is published by Wolters Kluwer.
