Researchers from LMU and Cornell University reveal that zebrafish and fruit flies share the same internal compass mechanism.

PHILADELPHIA—By analyzing genetic data from nearly 2 million people, researchers have unlocked a new scientific understanding of Ménière’s disease, a chronic and often debilitating inner ear disorder. A team from the Perelman School of Medicine at the University of Pennsylvania found evidence that the condition may be linked in part to how the inner ear develops early in life—rather than being caused solely by problems that arise in adulthood, as previously thought. The findings were published in the American Journal of Human Genetics.

Prior to 2021, poison control centers nationally received roughly 1,000 to 1,500 cases per year. After mid-2021, these volumes nearly doubled, and by 2023 poison centers logged more than 8,000 GLP-1RA-related calls.

Most cases stemmed from unintentional dosing or therapeutic errors rather than deliberate misuse, but the UT San Antonio researchers found the massive increase jarring nonetheless.
