Marine disease on the rise?

A new method by Jessica Ward and Kevin Lafferty confirms fears of rising distress in threatened populations, revealing a real underlying pattern in nature. Disease trends were found to increase in all groups except seagrasses, decapods, and sharks/rays, while fishes experienced decreased disease reports.

Imaging the brain solving problems through insight

Studies using fMRI and EEG reveal a distinct neural activity pattern in the right hemisphere's anterior Superior Temporal Gyrus (aSTG) associated with insightful problem-solving. This finding suggests that insight involves integration of distantly related information, providing new insights into cognitive processes.
