Listening to mix of sounds and silence preserves temporal sound processing in mice

Technique holds promise as non-invasive intervention for sensorineural hearing loss

Listening to mix of sounds and silence preserves temporal sound processing in mice
2021-06-21
(Press-News.org) Broadband sounds embedded with short pauses can maintain temporal sound processing in a mouse model of hearing loss, according to new research published in eNeuro.

Hearing loss treatments supplement auditory system function but don't repair it. However a new intervention -- playing broadband sounds during the onset of hearing loss -- may be able to prevent the damage from ever occurring. Augmented auditory environments have been able to preserve auditory processing of a wide range of sound frequencies in mice models. In a new study, Dziorny et al. modified the traditional paradigm and preserved the processing of time-related, or temporal, sound features which are vital for understanding speech.

The research team exposed mice with congenital hearing loss to traditional augmented auditory environment, and a new one with almost undetectable gaps of silence. After 12 hours of exposure per day for 20 to 22 days, the team tested the animals' response to sound in their brainstems, cochleas, and midbrains. Both interventions preserved sound processing function in all three areas compared to mice that didn't receive treatment. They also prevented hair cells from dying. But the version with gaps went even further: it maintained the ability to process temporal qualities of sounds. Augmented auditory environments show promise as non-invasive intervention to minimize the effects of congenital hearing loss.

RUDN University doctors found out the role of macrophages in liver regeneration

RUDN University doctors found out the role of macrophages in liver regeneration
2021-06-21
RUDN University doctors found out what role macrophages play in the recovery of the liver after the removal of its significant part. The results are published in the journal Biomedicine & Pharmacotherapy. The liver in mammals is the most regenerative internal organ. It can restore the original size from as little as 25% of the preserved tissue. An important role in this process is played by macrophages. These are the cells that can engulf and digest particles. It is known, for example, that if the liver is affected by foreign substances, including drugs, macrophages migrate to the liver, absorb harmful microorganisms and dead cells, cause inflammation and thus contribute to the restoration of the organ. However, it is still unknown unambiguously how macrophages affect the ...

Third of Americans use gray market caregivers to aid the elderly and those with dementia

2021-06-21
Nearly a third of Americans who arranged for paid care for an older person or someone with dementia employed workers who were not hired through a regulated agency, according to a new RAND Corporation study. Individuals who hired gray market caregivers were less likely to be employed and more likely to also use unpaid care for their family members. In addition, people who lived in rural areas had an almost five-times higher odds of arranging dementia care through gray markets as compared to those who lived in urban areas. The study is the first national survey to probe the use of gray market care for older adults and people with dementia. The findings ...

HOUSTON - (June 21, 2021) - Rice University engineers have created microscopic seeds for growing remarkably uniform 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight. Halide perovskites are organic materials made from abundant, inexpensive ingredients, and Rice's seeded growth method addresses both performance and production issues that have held back halide perovskite photovoltaic technology. In a study published online in Advanced Materials, chemical engineers from Rice's Brown School of Engineering describe how to make the seeds and use them to grow homogenous thin films, highly sought ...

New research unlocks the mystery of New England's beaches

New research unlocks the mystery of New Englands beaches
2021-06-21
AMHERST, Mass. - Millions of Americans will visit New England's beaches this summer to cool off, play in the waves and soak up the sun. Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly in a steep drop-off have been largely unknown. However, new research from the University of Massachusetts Amherst reveals, with unprecedented detail, how the grain size of beach sand relates to the slope of the beach itself. These new findings are critical to understanding how New England's beaches will respond to both rising sea levels and increased storm activity. Many of New England's beaches are made up of a mixture of sand and small stones. Or, to be more precise, the grain sizes on these beaches are "bi-modal" ...

New cold atom source lays groundwork for portable quantum devices

New cold atom source lays groundwork for portable quantum devices
2021-06-21
WASHINGTON -- Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum devices, researchers have developed a new high-flux and compact cold-atom source with low power consumption that can be a key component of many quantum technologies. "The use of quantum technologies based on laser-cooled atoms has already led to the development of atomic clocks that are used for timekeeping on a national level," said research team ...

Japanese, Italian, US physicists reveal new measurements of high-energy cosmic rays

Japanese, Italian, US physicists reveal new measurements of high-energy cosmic rays
2021-06-21
New findings published this week in Physical Review Letters, Measurement of the Iron Spectrum in Cosmic Rays from 10??GeV/n to 2.0??TeV/n with the Calorimetric Electron Telescope on the International Space Station, suggest that cosmic ray nuclei of hydrogen, carbon and oxygen travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. A series of recent publications based on results from the CALorimetric Electron Telescope, or CALET, instrument on the International Space Station, or ISS, have cast new light on the abundance of high-energy cosmic ray nuclei -- atoms stripped of their ...

Researchers discover how the intestinal epithelium folds and moves by measuring forces

Researchers discover how the intestinal epithelium folds and moves by measuring forces
2021-06-21
The human intestine is made up of more than 40 square meters of tissue, with a multitude of folds on its internal surface that resemble valleys and mountain peaks in order to increase the absorption of nutrients. The intestine also has the unique characteristic of being in a continuous state of self-renewal. This means that approximately every 5 days all the cells of its inner walls are renewed to guarantee correct intestinal function. Until now, scientists knew that this renewal could take place thanks to stem cells, which are protected in the so-called intestinal crypts, and which give rise to new differentiated cells. However, the process that leads to the concave shape of the crypts and the migration of new cells towards the intestinal peaks was unknown. Now, an international ...
