Science or Fiction (1:32:08)[edit]
Item #1: Scientists have been able to create a DNA based nanomotor that can convert electricity into kinetic motion, and in which they can control the direction and speed of the rotation.[5]
Item #2: A decade-long investigation finds that about 20% of moth species, representing thousands of species, produce ultrasound to deter bats by either jamming or confusing their echolocation or serving as warnings of toxicity.[6]
Item #3: A new simulation of Jovian planet ring formation indicates that Jupiter likely had a massive ring system throughout most of its existence.[7]
