Geography The island is north of the country's capital, Malé. Ecology Vaadhoo island is famous for the 'sea of stars.'

Woodland Hastings of Harvard University has for the first time identified a special channel in the dinoflagellate cell membrane that responds to electrical signals—offering a potential mechanism for how the algae create their unique illumination.
