Scientists at the Paul Scherrer Institute PSI have refined an X-ray diffraction technique for detecting biological structures from nanometers to millimeters—reducing the time needed to make the ...

The vertebrate ear is a remarkable structure. Tightly encapsulated within the densest bone of the skeleton, it comprises the smallest elements of the vertebrate skeleton (auditory ossicles) and gives ...

Scientists have scanned the skulls of Neanderthals and found the small middle ear ossicles, which are important for hearing, still preserved within the cavities of the ear. To their surprise, the ...

FEW problems in morphology have aroused more interest than that of the origin of the ear ossicles. It is a familiar fact that the Mammalia differ from all other gnathostomes in having a chain of three ...

Otosclerosis is one of many hearing disorders found only in humans, affecting the otic capsule. It occurs when the joints between the ossicles in the middle ear become hardened with age. The formation ...

Scientists at PSI were able to observe the local collagen structures in an ossicle by scanning it with an X-ray beam. The different colours of the cylinders indicate how strongly the collagen bundles ...
