Berly McCoy and Regina Barber of Short Wave talk about a hawk's clever hunting strategy, contacts that allow wearers to see infrared light, and how immunity varies during the day.

But, in a breakthrough of unprecedented proportions, scientists at the university have created contact lenses that make humans see infrared light even when their eyes are closed.

Researchers have finally figured out how mosquitoes see humans in the dark: They detect infrared light the body generates via heat.

Infrared light exposure, which is similar but not the same as red light therapy, should be limited to no more than 20 minutes in some instances.
