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 ...

Air conduction and bone conduction: the way sound reaches us is fundamentally differentWhen we listen to conversations in our ...

Three bones—among the tiniest in the human body—sit in your middle ear, where they transmit vibrations from the eardrum to the cochlea, significantly sharpening your hearing. Collectively known as 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 ...

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 ...

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 ...

Asier Gómez-Olivencia, an Ikerbasque researcher at the UPV/EHU, has led a piece of research that has produced a 3D reconstruction of the remains of a two-year-old Neanderthal recovered from an ...

In 1948, researchers stressed a nursing mother with ice water, toe pulling, and math problems with shocks. Each time, her baby got less milk. The Old Farmer's Almanac predicts snow in the Upper ...

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 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 ...
