“In spite of the presumed relevance of wrinkles on facial age, the topic has received little attention in empirical literature.” Prompting J.Antonio Aznar-Casanova (University of Barcelona, Spain) along with Nelson Alves (Universidade Federal da Paraíba, Brazil) and Sérgio S Fukusima (University of São Paulo, Brazil) to perform a set of two experiments to help clarify […]

Towards a ‘Wrinkly Fingers’ Explanation [study]
The mystery of wrinkly fingers may be a step closer to an explanation. “Everyone has experienced wrinkly fingers after an extended exposure to water. These wrinkles have been proposed as an evolutionary mechanism for a better grip of wet objects. However, besides experimental observations or mathematical theories, there is still not a clear agreement whether […]
Wrinkled sheets, crumpled paper
New research about how paper crumples was done in the same chunk of Harvard that produced an Ig Nobel Prize-winning study about how sheets get wrinkled. It builds on—and adds new wrinkles to—that earlier research. Siobhan Roberts reports, in the New York Times, about the paper-crumpling study: This Is the Way the Paper Crumples In a […]
Why Are Bird Eggs Bird-Egg-Shaped? [New research from an Ig Nobellian]
Mahadevan, who won an Ig Nobel Physics Prize in 2007 for studying how/why wrinkled sheets become wrinkled, has a new study out about how/why bird eggs become bird-egg shaped. The study, by Mahadevan and several collaborators, is: “Avian Egg Shape: Form, Function, and Evolution,” Mary Caswell Stoddard, Ee Hou Yong, Derya Akkaynak, Catherine Sheard, Joseph […]
‘Spock,’ ‘Joker,’ & ‘Mephisto’ eyebrows – avoidance techniques for aesthetic surgeons
Aesthetic surgeons in the business of facial wrinkle reduction have noted that if one weakens the glabella muscle with injections of AbobotulinumtoxinA without also weakening the frontalis muscle, unwanted side effects can occur. Known in the trade as ‘Spock,’ ‘Joker,’ or ‘Mephisto’ eyebrows. These side effects can be avoided by also injecting the fontalis muscle […]
No more disheveled kilts? (new patent)
Attention kilt wearers! Does your kilt sometimes look, well . . . wrinkled, matted or otherwise disheveled? Is it hanging properly? If not, help is at hand from inventor Joseph E. Austin of Las Vegas, US. “Like other garments, kilts have been stored and hanged using conventional hangers. Unfortunately, kilts are not like other garments […]
Another wrinkle in the wrinkled-fingers investigation
A new German study snaps its fingers, metaphorically, at recent studies of human finger-wrinkling: Finger Wrinkling (2014, not gripping) “Water-Induced Finger Wrinkles Do Not Affect Touch Acuity or Dexterity in Handling Wet Objects,” Julia Haseleu, Damir Omerbašić equal, Henning Frenzel, Manfred Gross, Gary R. Lewin, PLoS ONE, 9(1), 2014, e84949. (Thanks to Achim Reinsdorf for […]
Emotional Gauging of Students via Forehead Wrinkle Extraction
It’s not always easy to gauge whether students have understood lesson content (or not). Perhaps an automated measuring system could be devised – measuring their forehead wrinkles for example? At least two scholarly texts are available for those interested in the possibilities offered by forehead wrinkle evaluation in the classroom. The first is provided by […]
On and in crumpled paper
Crumpled paper fascinates physicists, most of whom nevertheless continue to throw away most of the paper they crumple. But some do pause to analyze what they’ve wrought. Wired reports about a recent case of this: “Crush a piece of typing paper into the size of a golf ball, and suddenly it becomes a very stiff […]
