Karaoke endurance / Kinetics and monkeypox / lint as renewable / biosupercapacitor

This week’s Feedback column (that I write) in New Scientist magazine has four segments. Here’s how each of them ends:

  • Sing it loud—… One implication from that intensive Hong Kong experiment: most karaoke singers manage to keep the quality of their singing fairly constant, no matter what.
  • Kinetic excitement— … Then the word “kinetics” takes centre stage, in this dramatic passage: “To the best of our knowledge, the kinetics of symptom onset in both patients and, subsequently, in their dog suggest human-to-dog transmission of monkeypox virus.”
  • Greenwashing— … The researchers make and – in an exploratory way – test a simple solution: collect the lint from clothes dryers and burn it to produce a hitherto-neglected “sustainable source of renewable energy”.
  • Perspiration inspiration— … The researchers assure us that “the wearable device can store energy and deliver high-power pulses long after the perspiration stopped”. (A technical concession for the persnickety reader: Habitually naked except for a wearable biosupercapacitor.)
