Stereocilia, the tiny actin-filled protrusions that crown inner-ear hair cells and form staircase-like bundles essential for hearing, arise through a carefully choreographed sequence of changes on the cells’ apical surface, according to a new study of the developing mouse cochlea…
A robotic hand fitted with 3D-printed sensor module developed by the research team. (Credit: Sravanthi Yalamanchili/WSU) An electronic skin with a sensing system that can detect pressure and temperature could someday be used to help amputees gain feeling in…
A new study shows similarities and differences in human and insect vision formation. The researchers at the University of California, Irvine discovered profound similarities and surprising differences between humans and insects in the production of the critical light-absorbing molecule of…
A mouse study finds that the transcription factor Sox3 preserves the actin core of hair cell stereocilia, and that its loss causes progressive hearing loss while its overexpression protects against noise damage.
In gerbils, multichannel LED-based optical cochlear implants combined with ChReef gene therapy achieved spectrally distinct auditory midbrain activity at clinically feasible light energies.
An essential protein that acts as a gatekeeper for calcium entering cells promotes the growth of oral cancer and generates pain, according to a new study published in Science Signaling led by researchers at NYU College of Dentistry. Targeting this…
A study published in Nature maps a deep, difficult-to-reach brain region in unprecedented detail, revealing how it processes physical sensations and communicates with areas involved in cognition and emotion. “Contrary to previous thinking, the insula is ‘not just reading the…
Bioengineer.org A comparative study of multiscale neural recordings found a broadly shared profile of brain activity during anesthesia in humans, macaques, marmosets, mice, zebrafish and nematodes Across the six species, anesthesia was associated with shorter intrinsic timescales of local…
They also performed better in tests of motor function, gait coordination, grip strength and endurance. The findings describe experimental effects in mice and do not demonstrate that NMN can treat spinal cord injury in people. Spinal cord injury can produce…
The Canute Scientific looks like a computer keyboard - but with holes and gaps through which the dots pop up and down A blind university lecturer says a new braille device could help people with sight loss study and work in…
How people and other animals sense the world: vision, hearing, smell, taste, touch, pain and itch, and the sensory neurons behind them.
