What Mummy Said, Sort of, 3000 Years Later

January 24th, 2020

This report sounds like it is saying that the authors managed to hear what a person who became a mummy sounded like before he became a mummy.

The report is: “Synthesis of a Vocal Sound from the 3,000 Year Old Mummy, Nesyamun ‘True of Voice’,D.M. Howard [inventor of the Vocal Tract Organ], J. Schofield, J. Fletcher, K. Baxter, G.R. Iball, and S.A. Buckley, Scientific Reports, vol. 10, no. 45000, 2020. The authors, at Royal Holloway, University of London, UK; the University of York, UK; Leeds General Infirmary, UK, and the University of Tübingen, Germany; report:

“The sound of a 3,000 year old mummified individual has been accurately reproduced as a vowel-like sound based on measurements of the precise dimensions of his extant vocal tract following Computed Tomography (CT) scanning, enabling the creation of a 3-D printed vocal tract. By using the Vocal Tract Organ, which provides a user-controllable artificial larynx sound source, a vowel sound is synthesised which compares favourably with vowels of modern individuals.”

The Vocal Tract Organ

What is a Vocal Tract Organ? The Bibliolore blog talked about that, so to speak, in 2015:

“The vocal tract organ is a new musical instrument that consists of three-dimensional (3D)-printed vocal tracts (throat and mouth) for individual vowels sitting on loudspeakers to enable static vowel sounds to be produced. The acoustic excitation from the loudspeakers is a synthesized version of the typical waveform produced by the vibrating human vocal folds during pitched sounds, which enables the instrument to be played from a keyboard….”

The mystery of how some animals lock themselves into place

January 22nd, 2020

Benno Meyer-Rochow, who won an Ig Nobel Prize in 2005 for calculating the pressures produced when penguins poo [see diagram, below] is now investigating a different kind of biological mystery.

Meyer-Rochow wrote an essay that begins:

You can lock arms with someone, you can lock on to something or be locked in or even be locked up or locked out. But this essay is about animals that possess locking mechanisms. In the tropical waters of Ascension Island in the South Atlantic Ocean, for example, I once caught a pair of matchbox-sized trigger fish and observed their behaviour in my aquarium on board of the research vessel “Walter Herwig”. These denizens of the tropical seas as well as their cousins, the file fishes, can wedge themselves into rock cracks and coral crevices in such a way that it is virtually impossible to dislodge them by pulling at their tails.

You might think that these fish must be mighty strong, but in reality they hardly use any energy at all in this process of “locking in”. Their first dorsal fin ray is a spine that possesses a groove on the backside; but when fully erect a smaller second spine behind the first one is pushed home into the groove of the spine in front, so that the first bigger spine cannot be depressed by external forces, except when the second smaller one is retracted first. A very fine and effective device that is….

Sad news: Terry Jones is dead

January 22nd, 2020

Terry Jones has died. His achievements as a Monty Python, and as a writer, director, and actor in other realms, are well and duly celebrated. He was a very nice and good person. And rather funny.

We were lucky to have collaborated with him on some small things. Here are two performances of bad poetry by William McGonagall. The second video features Terry with Dr. Elena Bodnar, Ig Nobel Prize-winning inventor of the Emergency Bra, a device that in an emergency can be quickly separated into a pair of protective face masks:

Terry was going to be the English language narrator on the Ig Nobel Operas television series, a project that was launched with great excitement about eight years ago but (in the tradition of the television industry!) disintegrated for nonsensical business reasons.

“Big Men” in leadership roles [new study]

January 20th, 2020

How does body weight and size affect the perceived persuasiveness of ‘leaders’ (when the ‘leader’ is a man) ? This question has recently been examined by three professors from the Dyson School of Applied Economics and Management, Cornell University, US. Professor Kevin Kniffin and Professor Vicki  Bogan, along with faculty colleague Professor David Just (also now at Universita degli Studi di Catania, Italy), present a series of six studies :

“[…] in which we find that the anthropological concept of “big men” can carry literal meaning–in relation to “big”ness and “men”– in contemporary settings.”

Alongside the finding, the authors caution that prospective ‘leaders’ should exercise restraint with the idea of deliberately putting on more weight in order to enhance their gravitas.

“Our findings do not suggest that men should acquire more weight to be viewed as more persuasive; […]”

As can clearly be seen in the graph below :

Note : PLOS ONE is a rebranded version of the journal previously known as PLoS ONE. The diminutive ‘o’ in the original logo having been replaced, in 2012, by a more imposing big ‘O’.
