High school students describe two new species of scorpions

California now has two new scorpions on its list of species, thanks to the efforts of two keen-eyed high school students from the Bay Area and the California Academy of Sciences. Harper Forbes and Prakrit Jain, avid users ...

Molecular 'blueprint' illuminates how plants perceive light

Plants rely on their ability to sense light for survival. But unlike animals, plants don't have eyes full of photoreceptors to capture and convey messages from visual stimuli. Instead, plants are coated with a network of ...

Mathematical modeling shows why animals see at night

Nocturnal and diurnal mammals see the sameā€”but only for a brief time. When mice are born, the chromatin in the cells of their eyes has a diurnal structure. Day by day, the layout of this chromatin slowly inverts, allowing ...

Muscle-like material expands and contracts in response to light
