Review of Nanomedicine

The field of nanomedicine holds vast potential for the improvement of health care around the world and the coming nanomedical revolution will surely bring innovative solutions to many of the difficulties we currently encounter in the realm of patient treatment. Nanomedicine is a relatively new field for scientific inquiry. It is defined as the use of nanoscale devices or materials to diagnose and cure diseases by actively interacting at the molecular level within a cellular system. In the context of nanotechnology, the “molecular level” refers to structures less than 100 nanometers in diameter. Given the breadth of this definition of nanomedicine, it can be narrowed and made more applicable when only those devices or medicines designed to function on the nanoscale are considere

Internally coupled ears in living mammals.

It is generally held that the right and left middle ears of mammals are acoustically isolated from each other, such that mammals must rely on neural computation to derive sound localisation cues. There are, however, some unusual species in which the middle ear cavities intercommunicate, in which case each ear might be able to act as a pressure-difference receiver. This could improve sound localisation at lower frequencies. The platypus Ornithorhynchus is apparently unique among mammals in that its tympanic cavities are widely open to the pharynx, a morphology resembling that of some non-mammalian tetrapods. The right and left middle ear cavities of certain talpid and golden moles are connected through air passages within the basicranium; one experimental study on Talpa has shown that the middle ears are indeed acoustically coupled by these means. Having a basisphenoid component to the middle ear cavity walls could be an important prerequisite for the development of this form of interaural communication. Little is known about the hearing abilities of platypus, talpid and golden moles, but their audition may well be limited to relatively low frequencies. If so, these mammals could, in principle, benefit from the sound localisation cues available to them through internally coupled ears. Whether or not they actually do remains to be established experimentally.This is the final version of the article. It first appeared from Springer via http://dx.doi.org/10.1007/s00422-015-0675-
