NCBI ROFL: Why you overspend on Ebay.

The value of victory: social origins of the winner’s curse in common value auctions.

“Auctions, normally considered as devices facilitating trade, also provide a way to probe mechanisms governing one’s valuation of some good or action. One of the most intriguing phenomena in auction behavior is the winner’s curse – the strong tendency of participants to bid more than rational agent theory prescribes, often at a significant loss.

NCBI ROFL: The fluid mechanics of coffee rings.

By ncbi rofl | August 29, 2012 7:00 pm

Formation of coffee stains on porous surfaces.

“During the drying of drops of nanoparticle suspensions, segregation can occur by internal fluid flows toward the contact line, if the contact line is pinned. This leads to a characteristic ring deposit or coffee stain. On solid substrates coffee staining can be eliminated through the use of solvent mixtures that promote Marangoni flows to oppose these drying-induced flows. Read More

NCBI ROFL: Curvy vs. straight – which glass ups your drinking rate?

Glass Shape Influences Consumption Rate for Alcoholic Beverages

High levels of alcohol consumption and increases in heavy episodic drinking (binge drinking) are a growing public concern, due to their association with increased risk of personal and societal harm. Alcohol consumption has been shown to be sensitive to factors such as price and availability. The aim of this study was to explore the influence of glass shape on the rate of consumption of alcoholic and non-alcoholic beverages. Read More


Watch These Technicolor Squid Cells Dance to "Insane in the Brain"

By Veronique Greenwood | August 28, 2012 11:13 am

Insane in the Chromatophores from Backyard Brains on Vimeo.

The folks at Backyard Brains, a DIY-neurobiology project, made these pigment-producing cells in a dead squid pulse to the base beats of Cypress Hill’s “Insane in the Brain.” Go watch that thing right now.

Done? Wowed? Prepare to be more wowed: They did it by exploiting the fact that electrical current is key to both the actions of cells and the playing of mp3s. These pigmented cells, called chromatophores, are surrounded by muscle cells, and it’s by flexing these muscles that the squid reveals its colorful spots. By hooked up the nerve that sends the flexing orders to the wire of a set of earbuds, they got these amazing results.

NCBI ROFL: Smilies, emoticons scientifically proven not worthless.

By ncbi rofl | August 27, 2012 7:00 pm

Same same but different!? The differential influence of smilies and emoticons on person perception.

“Emoticons (ASCII-based character strings) and smilies (pictograms) are widely used in computer-mediated communication as substitutes to compensate for the absence of nonverbal cues. Although their usage has been investigated in numerous studies, it remains open whether they provoke differential effects and whether they lead to person perception patterns similar to what is known from face-to-face interactions.

Sexual and intimacy health of Roman Catholic priests.

“This study explores the sexual experiences and sexual health of Roman Catholic priests. The qualitative research design looked at priests’ responses to the question, “Please share one or more sexual experiences in your lifetime.” The qualitative responses were analyzed and categorized into seven groupings: Read More

NCBI ROFL: Disliked food acting as a contaminant in a sample of young children.

By ncbi rofl | August 23, 2012 7:00 pm

“Anecdotal evidence suggests that a disliked food can act as a contaminant to liked food during childhood. While this has been investigated in an infant sample, the current paper presents the first study to investigate this phenomenon in a sample of young children (4 years 5 months-6 years 1 month old, N=30). Children were shown a liked food at different stages of being contaminated by a disliked food. Read More

NCBI ROFL: Measuring the distribution of spitefulness.

By ncbi rofl | August 22, 2012 7:00 pm

“Spiteful, antisocial behavior may undermine the moral and institutional fabric of society, producing disorder, fear, and mistrust. Previous research demonstrates the willingness of individuals to harm others, but little is understood about how far people are willing to go in being spiteful (relative to how far they could have gone) or their consistency in spitefulness across repeated trials. Our experiment is the first to provide individuals with repeated opportunities to spitefully harm anonymous others when the decision entails zero cost to the spiter and cannot be observed as such by the object of spite.

NCBI ROFL: The vomiting of the shrew.

By ncbi rofl | August 21, 2012 7:00 pm

Effect of daily linear acceleration training on the hypergravity-induced vomiting response in house musk shrew (Suncus murinus).

“The effects of repeated linear acceleration training and the antimotion sickness drug, promethazine, on hypergravity-induced motion sickness were examined in musk shrew (Suncus murinus), which is known to show a vomiting response to motion stimulation. Animals were assigned into five groups: vestibular intact, untreated animals (Sham), vestibular lesioned (VL) animals, vestibular intact animals with promethazine hydrochloride administered as daily drinking water (Prom), vestibular intact animals who underwent horizontal linear accelerator motion training (Train), and vestibular intact animals treated with both promethazine hydrochloride and linear acceleration training (Prom+Train).

NCBI ROFL: Hey med students, apparently you can publish your mnemonic devices!

By ncbi rofl | August 20, 2012 7:00 pm

Musculoskeletal mnemonics: differentiating features.

“Mnemonics are often used in musculoskeletal radiology to help radiologists remember long differential diagnoses. However, unless the specific appearance of each entity on a differential is also recalled, mnemonics become useless. This article presents 8 mnemonics with their corresponding differential diagnoses and distinguishing features. Read More
