Raven: Mixed Up Mixed Theory of Madmen?

Thursday, December 18th, 2014

Michael J. Raven of the University of Victoria presents his view of a particular view of lunatics:

ravenIs Lewis’s Mixed Theory Mixed Up?Michael J. Raven, Theoria, vol. 79, no. 1, February 2013, pp. 57–75. Quothe Raven:

“My aim is to rekindle interest in David Lewis’s (1983) infamous but neglected Mixed Theory of mental states. The Mixed Theory is a mix of physicalism and functionalism designed to capture the intuitions that both Martians and abnormal human Madmen can be in pain. The Mixed Theory is widely derided. But I offer a new development of the Mixed Theory immune to its most prominent objections.”

What’s Eating You, and/or Vice Versa: Microbes

Wednesday, December 17th, 2014

If you enjoyed the new opera “What’s Eating You“, which was about two people and all the microbes in and on them, you will (probably) enjoy this newly published study. It’s about people, their microbes, and who eats whom:

The microbes we eat: abundance and taxonomy of microbes consumed in a day’s worth of meals for three diet types,” Jenna M. Lang [pictured here], Jonathan A. Eisen, Angela M. Zivkovic, PeerJ, epub December 9, 2014. The authors, at the University of California, Davis, report:

lang“Far more attention has been paid to the microbes in our feces than the microbes in our food…. Little is known about the effects of ingested microbial communities that are present in typical American diets, and even the basic questions of which microbes, how many of them, and how much they vary from diet to diet and meal to meal, have not been answered.

“We characterized the microbiota of three different dietary patterns in order to estimate: the average total amount of daily microbes ingested via food and beverages, and their composition in three daily meal plans representing three different dietary patterns.”

Maddie Stone gives further details about the study, in Motherboard.

The opera premiered as part of the 2014 Ig Nobel Prize ceremony. You may have heard a snippet, at the tail end of the recent Science Friday radio broadcast. You can see and hear the complete opera (all three acts) in this video of the Ig Nobel ceremony:

BONUS: Retraction Watch reports the case of a scientific paper, about gut microbes, apparently having eaten pieces of lots of other scientific papers about gut microbes.

BONUS: The same kind of “what microbes does it eat?” analysis could be performed on other animals. This video shows a cat eating some of the contents of a seafood shop in Vladivostok, reports the Death and Taxes blog. (Thanks to Betsy Devine for bringing it to our attention):

 

Brain transplants : the implications [4 of n]

Wednesday, December 17th, 2014

Prof_SvenaeusAmongst the formidable complexities that would be involved in transplanting someone’s brain, lurks an enigmatic question – if it were yours, would ‘you’ go with your brain? Such questions have been examined by professor Fredrik Svenaeus, of Södertörn University, Huddinge, Sweden. The professor has a chapter in ‘The Body as Gift, Resource, and Commodity’, ( Södertörn Studies in Practical Knowledge 6, 2012) entitled ‘The Phenomenology of Organ Transplantation: How does the Malfunction and Change of Organs have Effects on Personal Identity’

“If I get a new brain I (at least possibly) become another person. In this sense, the brain is the only organ that cannot be donated; if you offer your brain to be transplanted into another body, you become a receiver, not a donor, of organs.”

But ultimately the professor reminds us that, at least until 2070 or so (when he predicts the first brain transplant might take place) we will just have to be patient for firm answers :

“To get one’s brain transplanted into a new body will probably be a different kind of personality change than going through an existential crisis. Maybe puberty, or pregnancy, could be helpful as comparisons when we consider what getting a brain transplant (getting your brain a new body) would be like, but these real-life examples will not get us very far. We simply have to wait for the event to take place to be able to answer the change-of-identity question.”

Winningly cute animals of science

Wednesday, December 17th, 2014

Nature magazine assembled this video of the alleged Year’s Ten Cutest Animals in Science.

Number 9 was awarded the 2014 Ig Nobel Prize for biology:

When you watch and listen to the video, pay special attention to the narrator’s very first sentence. It’s a not-so-subtle, friendly dig at Nature‘s rival journal, Science.
