The light from the lamp (1.) functions as a detectable change in the plant's environment. As a result, the plant exhibits a reaction of phototropism--directional growth (2.) toward the light stimulus. Auxin distribution controls phototropism. 1. Sunlight strikes the plant from directly above. Auxin (pink dots) encourages growth straight up. 2 ...

The Bahamas has “firmly rejected” President-election Donald Trump's proposal to fly deported immigrants out of the U.S. and into the small island nation about 100 miles southeast of Florida ...
Heliography [a] is an early photographic process, based on the hardening of bitumen in sunlight. It was invented by Nicéphore Niépce around 1822. [ 1 ] Niépce used the process to make the earliest known surviving photograph from nature, View from the Window at Le Gras (1826 or 1827), and the first realisation of photoresist [ 2 ] as means to ...
