Do Frogs in Helium Get Squeaky Voices? (Podcast #94)

Do frogs get all high-voiced when they breathe in some helium, the way people do? A research study explores that very question, and we explore that study, in this week’s Improbable Research podcast. SUBSCRIBE on, iTunes, or Spotify to get a new episode every week, free. This week, Marc Abrahams discusses a published helium-filled study, with dramatic readings from Dany Adams, a biology professor at Tufts University […]

Animal squawks squeaks and songs (with helium)

Although a considerable body of scholarly work has examined the effects of Helium (2He) on human voice production [see, for example (Helium-assisted) High note research] we are by no means the only animals to have been investigated in this respect – here is a (non-exhaustive) list of examples of other creatures who have squawked, croaked, […]

Robots and humans interact – part 3 of 3

Improbable’s final (previous here) look at the RO-MAN Workshop 2012. – the 21st IEEE International Symposium on Robot and Human Interactive Communication, which was held September 9-13, Paris, France. Part 3 : Floating-in-the-air ‘bot ‘Humanoid’ robots go back a long way,  and nowadays there are numerous flying robots in the skies, but there are very […]

(Helium-assisted) High note research

Does subglottal resonance have a significant influence on register transition when singing falsetto? To find out, investigators at the University of Iowa decided on an innovative approach – involving helium. Or, more accurately, Helox (a.k.a. Heliox) a mixture of helium and oxygen [see safety note below]. Because helium is considerably less dense than normal air […]
