How the Mongolian gerbil may help speed recovery of a rare inner ear problem

Researchers developed a testing model to understand cognitive challenges of superior semicircular canal dehiscence (SSCD), a rare condition causing sound-induced dizziness and hearing abnormalities. The Mongolian gerbil model shows promise for accelerating recovery with reversible diagnostic findings characteristic of patients with SSCD.

New pumping strategy could slash energy costs of fluid transport by 22%

A new pumping strategy has been developed to slash energy costs of fluid transport by up to 22%. By switching pumps on and off, turbulent flows can be reduced, resulting in more efficient fluid transport. This approach could bring significant economic and environmental benefits, particularly for the transition to green energy.

Opportunistic pathogens are less likely to be present in the nose and throat of people vaccinated against COVID-19, who are also less likely to get severe disease compared to non-vaccinated individuals

A study found that vaccinated people are less likely to have opportunistic pathogens in their nose and throat, and also experience milder symptoms of COVID-19. This is attributed to the presence of transcriptionally active nasopharyngeal commensals, which play a key role in defining mild symptoms.

Review: No proof that indwelling catheters cause more UTIs than intermittent catheterization

A systematic review published in Topics in SCI Rehabilitation suggests that indwelling catheters do not increase the risk of urinary tract infections (UTIs) compared to intermittent catheterization. The review found that only three studies reported significantly higher UTI rates with indwelling catheters, but all three had critical flaws.
