Considering the missing science of retraining and maintenance in medical artificial intelligence, using ophthalmology as an exemplar | npj Digital Medicine - Nature

Preventable vision loss is a disproportionate global burden affecting low- and middle-income countries [1]. While contemporary frameworks highlight the pivotal role of sustained, capacity-building partnerships to address these inequities, current institutional offerings often fall short of this model [2]. Notably, prospective trainees seeking global health tracks may face limited publicly available information on structured opportunities across North America. Herein, we aimed to evaluate the documented global health training across accredited Canadian and US ophthalmology residency programs. We hypothesised that global health infrastructure remains limited and inequitably distributed. This cross-sectional study was conducted in accordance with Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

With 302 neurons, 200 of them in their heads, hermaphrodite female roundworms reveal surprising sex-specific differences in the nervous system and how these differences influence behavior, reproduction, and aging. Researchers at Northeastern University compared brain activity in male and hermaphroditic Caenorhabditis elegans, a microscopic worm widely used in biological research to understand how sex wires males and female nervous systems differently.

Artist’s concept of the new dinosaur species Invictibellatrix amberina, along with the fossil from which it was identified. The fossil had been sitting in a drawer for 100 years, until researchers pulled it out and became curious. Image via Sergey Krasovskiy and Pedro Salas/ Natural History Museum London.
