AbstractDiseases caused by retinal degeneration are major causes of irreversible vision loss worldwide (1). These disorders are characterized by the progressive loss of photoreceptor cells (rods and cones) in the retina, the light-sensitive layer at the back of the eye. However, the other neurons in the retina, including bipolar, amacrine, horizontal, and retinal ganglion cells, often remain largely functional, preserving the connection to the visual cortex via the optic nerve.

Passive Cooling A cool paintBrent GrocholskiConceptual drawing of combined evaporative-radiative cooling paint. The top and exterior of buildings can be used to passively cool, but this requires materials with the right properties to do so effectively. Fei et al. designed a paint that cools both radiatively and through evaporation and that appears to keep buildings relatively cool even in humid environments.

“Knowledge is power”—or at least it was when Sir Francis Bacon coined this phrase in the 16th century.
