| High air pollution from fracking in Ohio county Posted: 25 May 2022 08:09 AM PDT Residents of Belmont County in eastern Ohio have long suffered from health problems they suspected were the result of air pollution from fracking facilities, but regulators dismissed and downplayed their concerns. With technical assistance from volunteer scientists, local advocacy groups set up their own network of low-cost sensors. They found that the region's three EPA sensors were not providing an accurate picture: The sensors revealed concerning levels of air pollution, and correlations between local spikes and health impacts. |

| Desire for son in Nepal may impact on girls' health and wellbeing -- new study Posted: 24 May 2022 07:05 AM PDT The desire for a son could mean Nepali mothers stop breastfeeding infant daughters sooner, says new research. Girls in Nepal are breastfed for fewer months than boys on average, with girls with older sisters but no brothers being the most disadvantaged, says the study. And this shorter breastfeeding time is linked to a greater risk of death for Nepali infants in the study. |
| Cystic fibrosis: Restoring airway integrity Posted: 24 May 2022 07:05 AM PDT Cystic fibrosis is a rare genetic disease which can cause very serious symptoms. In particular, patients suffer from chronic bacterial infections that can lead to respiratory failure. It is caused by mutations in the CFTR gene, which regulates water movement across the cell membrane. Consequently, mucus quality is altered, it is no longer capable of capturing undesirable bacteria and expelling them. Using a model reproducing a respiratory epithelium -- a protective tissue composed of a monolayer of cells -- scientists have discovered that a simple film of liquid is sufficient to restore the airways' seal and reduce the risk of bacterial infection. |
| Human or seal? Who has the best underwater hearing? Posted: 24 May 2022 07:05 AM PDT We humans do better on land than under water -- also when it comes to our hearing.

| Deaf children with learning delays benefit from cochlear implants more than hearing aids Posted: 24 May 2022 07:05 AM PDT Typically, infants with hearing loss are first treated with hearing aids, and if these fail to help them develop early language and speech skills, they then become eligible for cochlear implants at 12 months or older. Cochlear implants -- considered the gold standard of treatment -- are small, electronic devices surgically placed under the skin that stimulate nerve endings in the ear to provide a sense of sound. A new study demonstrates the need for early cochlear implant use for deaf children, regardless of developmental impairments. |
