Researchers found that elephants' bone-conduction hearing is significantly improved due to their larger middle ear structures and ability to voluntarily close their ear canals. This allows them to transmit lower frequency sounds to the cochlea, enhancing low-frequency hearing by up to 30 times
A study published in PLOS ONE reveals a surprising diversity of Cretaceous reptiles at an Argentina fossil site. The research expands the known diversity of reptiles at the Cerro Fortaleza locality, which previously only preserved skeletal remains of giant sauropods.
A new fossil discovery has provided critical evidence for the evolution of the mammalian middle ear, revealing the first unequivocal evidence of the five auditory bones from an extinct group. The findings have narrowed the morphological gap between ancient and modern mammals.
The vertebrate ear's unique structure and development have puzzled scientists. A new study proposes that this complexity increased the
Researchers analyzed ear ossicles from 20 juveniles excavated in 18th-19th century burial grounds to understand maternal pre-pregnancy and late pregnancy diets. The study provides a unique link between diet and early pregnancy health.
Researchers applied new technological approaches to study the iconic Neandertal skeleton, identifying fossil remains, pathological conditions, and confirming deliberate burial. The study sheds new light on Neandertal anatomy, behavior, and cultural practices.
Researchers discovered conductive hearing loss is the most common type of hearing loss in Alagille Syndrome patients, affecting nearly one-third of all ears. CT scans revealed structural defects in the middle ear that vary in effect on hearing.
Researchers Dr Leandro Gaetano and Professor Fernando Abdala found significant differences in the shape of the stapes bone among Triassic cynodonts, even within the same species. The study sheds light on the evolution of the middle ear structure in basal cynodonts.
A 2-year-old Neanderthal child's skeleton has yielded new insights into the species' anatomy, including a complete stapes ossicle. This finding highlights significant morphological differences between Neanderthals and humans, with the exact relation to hearing in Neanderthals still unknown.
Recent studies of Mesozoic mammals in China reveal a diverse range of species, with many exhibiting mammalian characteristics. The findings provide insights into the evolution of the mammalian middle ear and the origin of mammals, with implications for our understanding of vertebrate biology.
Researchers at MIT have developed a new, low-power signal-processing chip that could lead to a wirelessly rechargeable cochlear implant without external hardware. The device uses the natural microphone of the middle ear and can be charged via an ordinary cell phone in two minutes.
A study led by Binghamton University anthropologist Rolf Quam analyzed two species of early human ancestor in South Africa, revealing a human-like malleus that suggests changes in the bone occurred early in human evolution. The findings provide new insight into human origins and may need to be updated to include changes in this bone.
A recent study by a team of researchers from Texas A&M University and Binghamton University has found that prehistoric ear bones could provide clues about human evolution. The discovery sheds new light on the development of modern humans and highlights the importance of studying ancient fossils.
Researchers have created a tiny, prototype middle-ear microphone that can be implanted in the ear to avoid problems with current cochlear implants. The device has been successfully tested in cadavers and aims to reduce size and improve sound detection abilities for future human testing.
The discovery of Liaoconodon hui, a complete fossil mammal from China, provides clear evidence of the transitional middle ear evolution in mammals. The specimen shows cartilage supporting the detached middle ear bones, shedding light on the evolutionary shift from reptiles to mammals.
A genetic mutation in the NOG gene causes autosomal dominant stapes ankylosis, a rare hearing loss syndrome with similar symptoms to otosclerosis. The syndrome is characterized by skeletal abnormalities and may require different treatment options.
