Some snakes lack the ‘hunger hormone.’ Experts are hungry to know why

The complex biology of ghrelin, the hunger hormone, has researchers wondering how its absence helps snakes last a long time with no food, if at all.

The evolutionary mysteries of a rare parasitic plant

At the base of mossy trees, deep in the mountains of Taiwan and mainland Japan or nestled in the subtropical forests of Okinawa, grows what most might mistake for a mushroom – but what is actually a very unique plant with some of the smallest flowers and seeds in the world. With no chlorophyll to photosynthesize with and no root system to supply it with water from the ground, Balanophora has evolved a series of extreme traits to survive entirely as a parasite on the roots of specific trees. Some species and populations produce seeds only without fertilization (obligate agamospermy) – which is exceedingly rare in the plant kingdom.    Researchers from the Okinawa Institute of Science and Technology (OIST), Kobe University, and the University of Taipei have now joined forces to survey Balanophora across its sparse and inaccessible habitats, upending our understanding of photosynthesis loss in land plants, obligate agamospermy, and the role of the plastids.
