Sudden vision loss in children: Study in China points to a novel retinal disorder

A multicenter study led by researchers from the State Key Laboratory of Ophthalmology in China has characterized a distinct retinal disorder in children following high fever illness. The study describes hyperacute outer retinal dysfunction (HORD), a condition marked by sudden bilateral vision loss, photoreceptor disruption, and variable recovery.

Even after learning the right idea, humans and animals still seem to test other approaches

Maybe it’s a life hack or a liability, or a little of both. A surprising result in a new MIT study may suggest that people and animals alike share an inherent propensity to keep updating their approach to a task even when they have already learned how they should approach it and even if the deviations sometimes lead to unnecessary error.
