In 1909, while harvesting a typical corn crop (Zea mays) in Illinois, a field worker noticed a plant so unusual that it was initially believed to be a new species. Its "peculiarly shaped ear" was "laid aside as a curiosity" and the specimen was designated Zea ramosa (from the...Light-sensing protein illuminates sun-loving ocean bacteria

He added that his study "is the first to report fast photocycles with the so-called blue proteorhodopsins. This means both blue and green proteorhodopsins can act as proton pumps" to harvest e...Research team receives $7.5 million to study cassava
