Links, Curiosities & Mixed Wonders – 12

Eli Bowen “the Legless Wonder” with his family welcome you to this new batch of oddities and news from around the world! Let’s start!

  • Could there be a solution to appeal vegans, vegeterians and meat lovers? It’s called post-animal bio-economy, and among other things it involves growing laboratory meat from stem cells.
    A totally painless method for animals, who could at last lead their happy lives without us giving up a steak, a glass of milk or a poached egg. These would note be alternative products, but the same products, developed in a much more sustainable way in respect to linear agriculture (which has proven problematic for the quantity of land, chemicals, pesticides, energy resources, needed water and work, and emissions of greenhouse gases).
    Take the highly controversial foie gras: in the near future it could be produced from the stem cells gathered from the tip of a duck’s feather. It might seem a bit sci-fi, but the first lab foie gras is already here, and this journalist tasted it.
    There are just two obstacles: on one hand, the costs of lab meat are still too high for large-scale production (but this shouldn’t take too long to fix); on the other, there’s the small detail that this is a cultural, and not just agricultural, revolution. We will find out how traditional farmers will react, and above all if consumers are rady to try these new cruelty-free products.

  • The city of Branau am Inn, in Austria, is sadly known as the birthplace of a certain dictator called Adolf. But it should be remembered for another reason: the story of Hans Steininger, a burgomaster who on September 28, 1567, was killed by his own beard. A thick and prodigiously long set of hair, which turned out to be fatal during a great fire: while escaping the flames, mayor Hans forgot to roll his 2-meters-long beard and put it in his pocket, as he usually did, tripped on it and fell down the stairs breaking his neck.
    As in the 1500s there was no such thing as the Darwin Awards, his fellow citizens placed a nice plaque on the side of the church and preserved the killer beard, still visible today at Branau’s Civic Museum.

  • But if you think silly deaths are an exclusively human achievement, hear this: “due to the humidity in its environment and how slowly a sloth moves, plant life will grow in its fur. This, combined with poor eyesight, leads to some sloths grabbing their own arms, thinking it’s a tree branch, and falling to their deaths.” (via Seriously Strange)

  • Furthermore, there’s the genius rodent who slipped into a 155-years-old mousetrap on exhibit in a museum. Slow clap.
  • You’re always so nervous and depressed, they said.
    Why don’t you learn a musical instrument, just to chill out and amuse yourself?, they said.
    It served them well.

  • The Flying Dutch of the 20th Century was called SS Baychimo, a cargo ship that got stuck in the Alaskan ice in 1931 and was abandoned there. For the next 38 years the ghost ship kept turning up and was spotted on several occasions; somebody even managed to board it, but each time the Baychimo successfully escaped without being recovered. (Thanks, Stefano!)
  • The terrible story of “El Negro”: when collectors of natural curiosities didn’t just ship animal skins back to Europe from the Colonies, but also the skin of human beings they dug out of their graves during the night.

  • Since we’re talking about human remains, the biggest traveling mummy exhibit was launched eight years ago (featuring a total of 45 mummies). You never got to see it? Neither did I. Here are some nice pictures.
  • Japanese aesthetics permeates even the smallest details: take a look at these two pages from a late-XVII C. manuscript showing the different kinds of design for wagashi (tipical pastries served during the tea ceremony. Ante litteram food porn.
  • Some researchers form the University of Wisconsin and the University of Maryland created music specifically studied to be appealing to cats, with frequences and sounds that should be, at least in theory, “feline-centric“. The tracks can be bought here even if, to be honest, my cats didn’t seem to be particularly impressed by the music samples. But then again, those two are fastidious and spoiled rotten.
  • An article published two years ago, and unfortunately still relevant today: transgender people have a hard time being recognized as such, even when theyr’e dead.

“Almost ready dear, let me put on some pearls and we can go out.”

  • Among the most bizarre museums, there is the wonderful Museum of Broken Relationships. It consists of objects, donated by the public, that symbolize a terminated relationship: the pearl necklace given as a gift by a violent fiancé to his girlfriend, in the attempt to be forgiven for his last abuses; an axe used by a woman to chop all of her ex-grilfriend’s furniture into pieces; the Proust volumes that a husband read out loud to his wife — the last 200 hundred pages still untouched, as their relationship ended before they’d finished reading the book. Well, can a love story ever last longer than the Recherche? (via Futility Closet)

In closing, I’d like to remind you that on Saturday 17 I will be in Bologna, at the library-wunderkammer Mirabilia (via de’ Carbonesi 3/e) to launch my new book from the Bizzarro Bazar Collection. You will also get to meet photographer Carlo Vannini and Professor Alberto Carli, curator of the Paolo Gorini Anatomical Collection. I hope to see you there!

Mouse serenade

Even mice sing.
We have known that for 50 years, but we are only recently beginning to understand the complexity of their songs. Part of the difficulty of studying mice songs lies in their ultrasonic vocalizations, frequencies the human ear cannot perceive: in the wild, this kind of calls happen for example when a mouse pup calls for his mother.

In April, in Frontiers of Behavioral Neuroscience, a new Duke University research appeared, showing how mice songs are really much more intricate than expected.
Researchers Jonathan Chabout, Abhra Sarkar, David B. Dunson and Erich D. Jarvis have exposed the mice to different social contexts and, using new specifically elaborated software, they have analysed the frequency modulation and duration of these ultrasonic calls. Researchers have been able to break down the songs into “syllables” and clusters of sound repeated to a certain rythm, and to discover how they vary according to the situation.

If a male mouse is exposed to female urine, and therefore gets convinced that she is somewhere nearby, his singing becomes louder and more powerful, if somewhat less accurate; to awake a sleeping female, he utilizes the same song, but the “syllables” are now pronounced much more clearly.
Female mice seem to prefer songs that are complex and rich in variations; even so, when a male finds himself near an available female, his elaborate courting song switches to a simpler tune. Once the potential mate has been attracted, in fact, our little mouse needs to save energy to chase her around and try to mate.

The mouse’s ability to sing is not as articulate as in songbirds; and yet, changes in the syntax according to social context prove that the songs convey some meaning and serve a precise purpose. Researchers are not sure how much mice are able to learn to modify their vocalizations (as birds do) or how much they just choose from fixed patterns. Forthcoming studies will try to answer this question.

It is nice to better understand the world of rodents, but why is it so important?
The goal of these studies is actually also relevant to humans. In the last decade, we understood how mice are extremely similar to us on a genetic level; discovering how and to what extent they are able to learn new “syllables” could play a fundamental part in the study of  autism spectrum disorders, particularly in regard to communication deficits and neural circuits controlling vocal learning.

Male mice song syntax depends on social contexts and influences female preferences, Jonathan Chabout, Abhra Sarkar, David B. Dunson, Erich D. Jarvis. Frontiers in Behavioral Neuroscience, April 1, 2015.
