Columbia University biomedical engineering professor Gordana Vunjak-Novakovic says that her team of researchers has grown a human jaw bone using stem cells taken from bone marrow. She says that the availability of personalized bone grafts created from a patient’s stem cells could revolutionize the way we treat bone disorders that can cause joints to deteriorate. Her technique in creating the jawbone was inspired by the body’s own processes.
Recent evidence indicates that bats have sensitivity to the geomagnetic field, and use it to navigate. When they are traveling miles from home at night they seem to guide their flight, at least in part, by using the magnetic field around them.
