Did His Orgasm Lead to Blindness? (podcast #93)

Wednesday, December 7th, 2016

Can a man’s orgasm cause him to go blind, at least temporarily? A medical report explores that very question, and we explore that medical report, in this week’s Improbable Research podcast.

This week, Marc Abrahams discusses a published orgasm/blindess study, with dramatic readings from Yale/MIT/Harvard biomedical researcher Chris Cotsapas.

The man who wants you to realize that reality is unrealistic

Friday, December 2nd, 2016

A professor cooks up some computer simulations, which convince him to try to convince everyone that reality is unrealistic. Amanda Gefter interviewed the professor, for The Atlantic magazine: “The Case Against Reality“.

Chimps Recognize Butts That Are Upside-Down, Too

Friday, December 2nd, 2016

A new study builds on prize-winning do-chimps-recognize-buttocks research, adding an upside-down appraisal:

Getting to the Bottom of Face Processing. Species-Specific Inversion Effects for Faces and Behinds in Humans and Chimpanzees (Pan Troglodytes),” Mariska E. Kret and Masaki Tomonaga, PLOS ONE, November 30, 2016. The authors, at Leiden University, the Netherlands, and Kyoto University, Japan, build on work, by other researchers, that won an Ig Nobel Anatomy Prize:

bodyparts

“In four different delayed matching-to-sample tasks with upright and inverted body parts, we show that humans demonstrate a face, but not a behind inversion effect and that chimpanzees show a behind, but no clear face inversion effect. The findings suggest an evolutionary shift in socio-sexual signalling function from behinds to faces, two hairless, symmetrical and attractive body parts.”

Leiden University issued a press release that gives further colorful details.

The 2012 Ig Nobel Prize for anatomy was awarded to Frans de Waal and Jennifer Pokorny, for discovering that chimpanzees can identify other chimpanzees individually from seeing photographs of their rear ends. They describe that research, in the study “Faces and Behinds: Chimpanzee Sex Perception“, Frans B.M. de Waal and Jennifer J. Pokorny, Advanced Science Letters, vol. 1, 2008, pp. 99–103.

Frans de Waal was pleased to see his Ig Nobel-winning research confirmed by this new study, he told the Dutch newspaper de Volkskrant: ‘Ik ben blij dat deze nieuwe studie dat bevestigt‘.

How much saliva does a five-year-old kid produce? (podcast #92)

Wednesday, November 30th, 2016

How do you measure how much saliva a five-year-old kid produces in a day? A Japanese study describes one approach, and we go with that flow (to an extent), in this week’s Improbable Research podcast.

This week, Marc Abrahams discusses a published saliva-filled study, with dramatic readings from Nicole Sharp, creator of FYFD, the internet’s most popular site about fluid dynamics. (She also does research on the Boston Molasses Flood.)

Galam’s Work on Galam Models (Reviewed by Galam)

Saturday, November 26th, 2016

In 2008, French physicist Serge Galam wrote a review article about “Galam models,” in which he cited 71 papers, all of which were written or cowritten by him.

                Serge Galam

Galam specializes in a topic known as “social physics” (or “sociophysics” for short), an area of complex systems that concerns the use of ideas and tools from physics to study collective social phenomena. Amidst the modern data deluge, sociophysics has become a very popular research area during the past decades, although the idea dates back multiple centuries and the term was first used more than two hundred years ago by French philosopher August Comte (1798–1857, credited as the founder of sociology).

There are numerous models in the physical study of social phenomena, and Galam reviewed the specific family of them known as “Galam models” in the article Sociophysics: A Review of Galam Models (available in published form at this website). The first sentence of the abstract provides a terse summary of the article’s contents: “We review a series of models of sociophysics introduced by Galam and Galam et al. in the last 25 years.” Below we excerpt the reference list (from the arXiv preprint of the paper) and show about half of the references.

The second half of the 71 references, each authored or coauthored by Serge Galam, in Serge Galam's review article on Galam models.

Thanks to investigator Renaud Lambiotte for bringing this paper to our attention.
