Male Scent Molecules May Be Compromising Biomedical Research

sciencehabit (1205606) writes "Scientists have found that mice feel 36% less pain when a male researcher is in the room, versus a female researcher. The rodents are also less stressed out. The effect appears to be due to scent molecules that male mammals (including humans, dogs, and cats) have been emitting for eons. The finding could help explain why some labs have trouble replicating the results of others, and it could cause a reevaluation of decades of animal experiments: everything from the effectiveness of experimental drugs to the ability of monkeys to do math. Male odor could even influence human clinical trials."

      Unfortunately, the summary is incorrect. The article says the mice are more stressed with males around.

      No, it's not. Modal has to do with different modes of learning, weird how it's exactly what it says eh?

      State specific or dependent memory is what you are looking for, which strangely enough has to do with the state of mind you're in.

      Weird how words work like that, eh?

    The male aroma ramped up their stress levels, which deadened the hurt.

    "Further testing showed that the rodents exposed to male odors were actually feeling less pain, rather than simply hiding the pain they were in. The male aroma ramped up their stress levels, which deadened the hurt. “It’s really astounding that such a robust effect could have been missed for so many years,” Mogil says."

    Here is another paper where the researches used a patch clamp to interface the spinal cord. (A patch clamp is a very low noise/high gain amplifier that can measure single cell ion channels, etc -- http://en.wikipedia.org/wiki/P...)

    I wonder what methods are typically used? Do researchers videorecord grimacing rats? That seems rather tedious and subjective.

    Bzzt. Oh, so sorry. The correct response was "Wow, I was a total dumbass for not reading the article. My idiotic knee-jerk rejection of this study based on the first stupid thought to cross my mind was completely wrong. I apologize for being a know-nothing smart-ass and promise not to do it again." Better luck next time!
