5 Most Bizarre Scientific Papers (PART 2)

«Impact of Wet Underwear on Thermoregulatory Responses and Thermal Comfort in the Cold»
(M. K. Bakkevig and R. Nielson; Sintef Unimed and Technical University of Denmark; 1995)
"The thickness of the underwear has the most influence on thermoregulatory responses"

The authors explain: "The purpose of this study was to investigate the significance of wet underwear and to compare any influence of fibre-type material and textile construction of underwear on thermoregulatory responses and thermal comfort of humans during rest in the cold. The tests demonstrated the significant cooling effect of wet underwear on thermoregulatory responses and thermal comfort. The thickness of the underwear has more of an influence on the thermoregulatory responses and thermal comfort, than the types of fibres tested."

«Navigation-Related Structural Change In the Hippocampi of Taxi Drivers»
(E. A. Maguire and others; University College London; 1999)
"The brains of London taxi drivers are more developed than those of their fellow citizens."

Authors at the University College London, about their research: "Structural MRIs of the brains of humans with extensive navigation experience, licensed London taxi drivers, were analyzed and compared with those of control subjects who did not drive taxis. The posterior hippocampi of taxi drivers were significantly larger relative to those of control subjects. A more anterior hippocampal region was larger in control subjects than in taxi drivers. Hippocampal volume correlated with the amount of time spent as a taxi driver (positively in the posterior and negatively in the anterior hippocampus). These data are in accordance with the idea that the posterior hippocampus stores a spatial representation of the environment and can expand regionally to accommodate elaboration of this representation in people with a high dependence on navigational skills. It seems that there is a capacity for local plastic change in the structure of the healthy adult human brain in response to environmental demands."

«Pressures Produced When Penguins Poo -- Calculations on Avian Defecation»
(V. Breno Meyer-Rochow and J. Gal; International University of Bremen and Lorand Eotvos University of Hungary; 2005)
"They get up, move to the edge of the nest, turn around, bend over... and shoot"

Ever wondered how far a penguin can fire waste from its anus? Wonder no more. Victor Breno Meyer-Rochow of International University, Bremen, and Jozsef Gal of Lorand Eotvos University, Hungary, used the basic principles of physics to calculate the pressure that builds up inside a penguin. Dr. Meyer-Rochow explained that the research began in 1993, when he led the first, and so far only, Jamaican expedition to the Antarctic. Later, while showing students pictures of faeces-lined penguin nests, he was asked how the elaborate displays were created. "They get up, move to the edge of the nest, turn around, bend over - and shoot," he said. That's when he got the idea to calculate the pressure produced by penguin poo.

«Farting as a Defence Against Unspeakable Dread»
(Dr. M. Sidoli; Washington DC; 1998)
"When feeling endangered, Peter used his bodily smell and farts to envelop himself in a protective cloud"

According to it's author, "this paper describes some features of the behaviour of a severely disturbed adopted latency boy. Peter was born premature, suffered several early hospitalizations and surgical operations, and at 2 months of age was removed from his mother's care by Social Services for neglect and abandonment. When feeling endangered, Peter had developed a defensive olfactive container using his bodily smell and farts to envelop himself in a protective cloud of familiarity against the dread of falling apart, and to hold his personality together."

«Ultrasonic Velocity in Cheddar Cheese as Affected by Temperature»
(A. Mulet, J. Benedito and J. Bon; Polytechnic University of Valencia; 2006)
"The most reliable temperature interval to carry out ultrasonic measurements in Cheddar cheese is identified as 0 to 17 °C."

The paper reads: "The ultrasonic velocity in Cheddar cheese is temperature dependent. This relationship can be used to make corrections when determining ultrasonic texture or to determine mean temperatures in cooling/heating processes. At 0 < style="border-bottom: 1px solid rgb(112, 58, 0); text-decoration: underline; color: rgb(112, 58, 0); font-size: 14px; font-weight: 400; font-style: normal; font-family: Georgia,Arial,Verdana;" class="IL_LINK_STYLE">Differential Scanning Calorimetry thermograms linked the temperature dependence of ultrasonic velocity to fat melting. Three parts are distinguished in the curve as a consequence of the fat melting and the appearance of free oil. The most reliable temperature interval to carry out ultrasonic measurements in Cheddar cheese is identified as 0 to 17 °C."
