World first research to speed up cure for ear infections

Fast tracking the healing process for common ear infections will be the focus of ground-breaking re...for the wound-healing process of an infected human ear drum. According to the World Health Organisation, almost half of the world's population suffers fro...

Rare Chinese frogs communicate by means of ultrasonic sound

...we are getting a better understanding of why their ear drums are recessed," Feng said. "Thin eardrums are needed for detection of ultrasound. Recessed ears shorten the path between eardrums and the ear, enabling the transmission of ultrasound to the ears." To test if the frogs actually communicated with...

Relationship of brain and skull more than just packaging

...e suture that runs across the top of the head from ear to ear. Children with craniosynostosis almost universally have surgery to reopen the sutures and allow normal growth of the boney plates of the skull. Premature closure of sutures causes the skull and the brain beneath to deform. However, the rese...

UF scientists trace origin of shark's electric sense

...y sense their environment, and organs of the inner ear that enable people to keep their balance. But scientists suspect as human ancestors emerged from the sea, they discarded their lateral lines as well as their ability to sense electrical fields. "Our fishy ancestors had the anatomy for it," said Jame...

Yale researchers find environmental toxins disruptive to hearing in mammals

...f boats might disrupt the balance of these ions in ear cells. "Our data are the first to directly show that chloride ions are crucial for our exquisite sense of hearing," said Joseph Santos-Sacchi, professor in the Departments of Surgery and Neurobiology and first author of the study in the Journal of N...

UCSD study reveals how plants respond to elevated carbon dioxide

...chroeder at UCSD, likened this priming to removing ear plugs from someone at a rock concert. "With very good ear plugs, someone might be able to sleep through the concert, but without the earplugs one would respon...

St. Jude finds clues to hearing loss from chemotherapy

A new understanding of how cells defend themselves against bacterial pore-forming toxins

...s, Streptococcus pneumonie, responsible for middle ear infections and pneumonia, and Helicobacter pylori, implicated in ulcers. Pore-forming toxins compose about a quarter of all known protein toxins that increase the infectivity and severity of bacterial diseases. Once the toxin perforates the host ...

Critical hearing gene helps send auditory messages to brain

Gene key to taste bud development identified

...and whether stem cells in the brain, eye and inner ear differentiate into specialized nerve cells. Taste bud cells, much like skin cells, continually slough off and are replaced by new ones. So the new findings not only provide insights into the interactions between SOX2 and tongue stem cells during em...

Clues to gene expression in cystic fibrosis will guide research

... serious side effects for some patients, including ear and kidney damage. The authors suggest that other drugs, such as amikacin or PTC124, with a comparable mode of action and fewer side effects, may have treatment potential. The in vitro method used to predict the trial’s outcome could be a first step...
