To support the question posed previously I have found limited literature. Regan and Llamas (2002) took a female confederate and dressed her in ‘gym casual’ or ‘formal business’ and sent her into female clothing stores and measured the time it takes for her to be served. Unsurprisingly, she was approached and served more quickly when [...]... Read more »

Sci actually considered blogging this paper as just a regular, run of the mill weekday paper…but it’s got urine sniffing. And the idea of making up a song to a paper is one that Sci can never resist.

The rather amusing cover of this month’s JEB caught my eye; I am always excited to find out about the outlandish and creative methods that scientists dream up in order to test their ideas. Yep, that’s a jumping spider holding a styrofoam ball, tethered to the ceiling. So what the heck could possibly be going [...]... Read more »

There was a very interesting study completed at the University of Michigan entitled When Corrections Fail: The persistence of political misperceptions by researchers Brendan Nyhan, School of Public Health, University of Michigan, and Jason Reifler, Department of Political Science, Georgia State University. This study, although in the realm of political behavior, has strong implications for science [...]

We like to think of ourselves as rational actors when it comes to making decisions, we take in information, process it and choose the path that we think will lead to a desirable outcome (if we aren’t deep-seated masochists I suppose).

Scientists have known for decades that the human intestinal tract is home to an abundance of diverse bacteria. This microbial rainforest is introduced incrementally to infants as they grow—primarily from their mothers during birth and breastfeeding and from everyday encounters. Many of these microbes aid in digestion and fight off pathogens, but until recently, researchers were not certain if phages, viruses that infect bacteria, were also present in the human gut.

I’m back at Chaco and giving tours again, so I’m once again being exposed to visitors’ common questions and preconceptions in a way I haven’t been in a long time.

Oil spills aren’t the only threat from giant floating oil rigs.

Imagine that there was no primate fossil record. No hominins, no Proconsul, Dryopithecus, no Eosimias, no Darwinius -- nothing. Now, given this dearth of fossil material, you could be excused for systematically organizing primates according to the stark divisions apparent between living species. Our species, while clearly a primate, would seem to stand by itself, [...]... Read more »

Odor is like fingerprints or facial features - it's unique. Yet no single measurement could be easily applied to recognize an individual. GC/MS measurements can be used to analyze mixtures of acids, alcohols, aldehydes, hydrocarbons, esters, ketones, and nitrogenous molecules in human odor. Complex algorithms mining patterns help to pinpoint the signatures. But could these signatures be easily derived from genetic makeups?Recent article published in the Journal of Chemical Ecology looked at ........ Read more »

It has been known for a long time that some anemones form symbiotic relationships with Zooxanthellae. For a while it was assumed that the anemones mainly persisted by utilizing carbon translocated from its symbionts, called autotrophy, but they can may supplement this by heterotrophic feeding on plankton.

The Eddington luminosity is the exact brightness a black hole has when the outwards and inwards forces on it balance.

DELETION of a single gene switches the sexual orientation of female mice, causing them to engage in sexual behaviour that is typical of males. Korean researchers found that deleting the FucM gene, which encodes an enzyme called fucose mutarotase, causes masculinization of the mouse brain, so that female mice lacking the gene avoid the advances of males and try to mate with other females instead. The findings probably have little relavence to human sexual orientation, however.

Back in the 1990s, paleontologist Jack Horner proposed that Tyrannosaurus rex—popularly cast as the most fearsome predator of all time—was really a giant-sized scavenger. With its small arms, a large part of its brain devoted to analyzing smells, and a mouth full of rail-spike-sized teeth, the tyrant dinosaur seemed to be better-suited to processing the [...]...
