Did you know that fruit fly antennal ears share many similarities with human ears?
Keder and colleagues (2020) report on the hearing sensitivity of the fruit fly (Drosophila melanogaster) across its lifespan of approximately 70 days.
Similar to human hearing, with age, hearing of the fruit files declines, with the hearing loss occurring after 50 days of life in the fruit fly.
The researchers, then, examined gene expression at days 1, 5, 10, 25, and 50 to determine what transcriptional regulator or homeostasis genes are responsible for maintaining healthy hearing before 50 days.
The researchers identified four transcriptional regulator genes associated with healthy hearing, all of which are also conserved in human ears. This findings are exciting because they have the potential to support future on novel pharmacological or gene-therapeutic strategies for humans.
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
The majority of people are familiar with earthquakes, but there is another phenomenon that is not nearly as predictable, and louder—skyquakes. Skyquakes are enigmatic sounds, typically described as a very loud boom or trumpet-sounding noise that has no apparent cause and seems to come from the sky. Their sound is like distant, but very loud, thunder with…
