I just saw these two things last night and thought they were impressive enough about what is possible with some elbow grease, a Ph.D, and a few billion dollars. So learn what it’s like to stand on the top of the Burj Dubai: It’s wobbly and tall. And it warms my heart to the hellhole that is Dubai. (gizmodo)

Closer to home, DARPA is paying the University of Maryland to weaponize maple seeds or samaras. That might seem insane, but watch the whole video to see what 3 years of research on single-wing rotary aircraft can get you. Go terps!?    (hackaday)

Don’t get “samara” confused with the city in Russia, or samsara, or you may experience endless cycles of misunderstanding.
