The solar-powered helicopter first became airborne at 3:34 a.m. EDT (12:34 a.m. PDT) – 12:33 Local Mean Solar Time (Mars time) – a time the Ingenuity team determined would have optimal energy and flight conditions. Altimeter data indicate Ingenuity climbed to its prescribed maximum altitude of 10 feet (3 meters) and maintained a stable hover for 30 seconds. It then descended, touching back down on the surface of Mars after logging a total of 39.1 seconds of flight. Additional details on the test are expected in upcoming downlinks…

Cleaner, quieter, more affordable flight is a focus for NASA aeronautics researchers who are currently pursuing aircraft propulsion technologies that could soon benefit the planet, the flying public, and American industry…
coronavirus: MOUSETRAPS AND PING-PONG BALLS DEMONSTRATE WHY SOCIAL DISTANCING WORKS
A video from the Ohio Department of Health shows a minefield of mousetraps and table tennis balls, row upon row, that turn into a predictable maelstrom of flying debris once a bouncing ball tumbles into view.
It’s also a metaphor for the menacing spread of the coronavirus, where just one person interacting with others can produce a chain reaction of devastating consequences.
Chordify presents new beattracking algorithm
…This year we present our research concerning semi-automatic enhancement of beat tracking. This is the perfect challenge for us, because we’re always looking for ways to improve of our algorithm.
A short explanation: to allow our users to change chords at the right moment we need an exact timestamp of the beat in an audio recording; and we do that by … exactly: tapping to the beat…
A Gorgeous Video of evolving resistance to antibiotics
THIS TIME-LAPSE IS one of the most compelling—and unsettling—visualizations of evolution we’ve ever seen. The overhead footage depicts a strain of the gut bacterium E. coli evolving to be 1,000 times more resistant to an antibiotic in a matter of 11 days, starkly visualizing the speed with which diseases can adapt to the drugs we throw their way.
