Researchers exposed baker's yeast cells to 2450 MHz microwave radiation (the same frequency as microwave ovens) and found the microwaves killed the cells even when temperatures were kept below lethal levels. The study used a special cooling system to separate thermal heating effects from potential non-thermal microwave effects, suggesting microwaves can damage living cells through mechanisms beyond simple heating.

Stevens' 1972 research identified an all-or-none step function in human sensory discrimination for both vision and hearing.
