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."
No more need to wear deodorant. My naturally musky smell will make everyone feel more at ease.
Shower more, filthy nerds :D
Maybe the male scientists need to shower more often...
Women are intimidating and cause stress. Film at 11.
What does a percent of lessened pain feel like? I can't even tell whether my throat hurts half as bad as it did yesterday or a fourth as bad, and that's from a first person perspective, the only perspective from which you actually have access to pain sensations.
I should also note that I'm not a mouse.
Well that stinks!
Does this suggest that female presence in a work place could reduce overall productivity and increase stress based on purely biological factors?
How do those little rodents feel when Richard Gere walks into the room?
Remember what the brown gerbil said to the white gerbil?
"You're new around here, aren't you."
No brain, no pain.
That's a very gender biased writeup.
"Male odor"?
The point is that males and females have consistently different odors in some way leading to a systematically different response by lab rats. You could just as well say it is the female odor that is breaking things. In reality it is a difference in response to different stimulus.
I should use this sig to advertise my book ISBN-13 : 978-1501515132.
Now we just have to figure out how to stop imposing our gender norms on dog's pain receptors.
I knew there was a reason I was always resistant to bathing.
Maybe the males are all neutral and the women are just nagging the animals to perform and causing too much stress!?
Do not meddle in the affairs of sysadmins, for they are subtle, and quick to anger.
I know female doctors make me nervous.
Same thing happens in the school yard - "No I ain' t crying, I just got some dust in my eye".
This is a psychological trick to avoid showing pain, not a biochemical trick to reduce pain.

The summary writes:
The rodents are also less stressed out.
The article writes:
The male aroma ramped up their stress levels, which deadened the hurt.
Was this the daily "Find the inconsistency" test on slashdot? Did I win something?
Can't find the article available for online reading, beyond http://www.nature.com/nmeth/jo...
But one wonders about the sample size and the statistical significance of the experiments.

Does this mean that it is ok to require that all lab assistants be female?
... but it's okay, because it's 'science', right?
Oh, wait... I forgot... I'm talking to the Slashdot sociopaths... children in adult bodies, who can't feel the suffering of others... must be really difficult, having to go through your entire lives never knowing love, and always having to PRETEND to give a toss about what others are going through...
This means that men treat the mice better than the women and they can feel that.
seem to feel threatened by this information.
plastic footed metal beetle space bugs, smell of laboratories, and live on soap.
is good to be human, in the information age, and i do hope these strange offspring of the petrochemical age die off soon..
yes, this is flame bait, however i am making the point that it is also further evidence that we have a problem, and this is news that matters, however many cannot handle that information.
I could easily believe that male hormones cause nearby animals to be more prepared to defend themselves and thus pain relief follows as an aid to flight or fight enhancements in the animal. This also demonstrates why variables should never exist in any scientific experiment and just how subtle a variable may be. The financial losses from decades of spoiled research could be considerable.

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.
This may be affecting experiments, but if you're designing your experiments correctly, it won't change your results. The "male in the room" effect should affect all animals the same.
You have a control set and a variable set of mice. The animal handlers should be the same for both, and they shouldn't know if at all possible which is which. Males on the staff will stress out the mice, okay, but they'll stress out both control and variable mice the same. Having a female undergrad handle the control cages and a male undergrad handle the variable mice you're using to try to prove your drug makes them hurt less is going to skew your results independent of gender scents.
Is this why females are more irritating in general?
"If any question why we died, Tell them because our fathers lied."
Either way, we make mice feel nice.

Rats react to women the same as if their was no observer?
Maybe we should she if women can observe things without changing states!
This would explain a lot of male confusion when women say two diametrically opposed things in the same sentence... They can just observe more quantum states than we can and can't understand why we cannot. :)
What's the baseline stress level? It would answer the question: do men cause 33% more stress or do women aleviate 33% stress? And I call bullshit on it anyway because I can tell you who stresses me out the most in order: my mom, my grandma, my sisters and my wife.

I've never felt pain while dreaming. that sounds like a weird experience!
“Common sense is not so common.” — Voltaire
...mice are sexist.
Not in the cases where you measure LEVELS of sensitivity to pain in some way.
Which basically includes every endurance or stress test.
They are "zeroed out" to a higher level.
Now your mice endure longer or don't start reacting as soon as they should have. So all your results are off by a third.
On top of that, someone tries to repeat your experiment - and their mice react differently.
There goes the peer review.
And that's just the pain. What else is influenced by inducing more stress?

"The rodents are also less stressed out"
And so are the male scientists, depending on what time of the month it is.
"everything from the effectiveness of experimental drugs to the ability of monkeys to do math"
Aha, so next time you're doing poorly on a math exam, tell the teacher that you need all the males to leave.
Evidently much LESS gets done with women around ... a kind of "least action" principle for sociodynamic. Intresting eh, but is that dysfunctional feminized environs REALLY the Rawlsian pervo-plus baseline you want to use?
I think frequency would be slightly more important here...you would want to maintain a suitable blood-alcohal level constantly, but then you could always spike it higher for those pesky 'dealing with the public' occasions. ;-)
Down With Slashdot BETA!!! I've been around the corner and seen the oliphant; you can only abuse me from your perspecti
attempt to ban women from labs. It is sick how their kind hates women and is willing to try to use dishonest science to justify their hatred of women.
I can only assume this was a clever experiment to make your lab assistants remove their shirts, for science.
I gots my stank on. C'mere and I'll let ya take a snootful of ma stank. Like that?
Seriously, now I need to take a hot shower for a few hours. Scrub!
After you cleanse with alcohol (or leave the shower) simply rub a half teaspoon or so of table salt into the dampened armpits to prevent the growth of body odor causing bacteria throughout the day. One may also use a salt solution to inhibit foot odor. There appears to be a link between Alzheimer's disease and the concentration of aluminum found in the brain which may have been absorbed via deodorants containing aluminum and/or food prepared in cookware containing aluminum. Thus, I also recommend against the use of aluminum foil -- Instead, use authentic vintage tinfoil for one's hattery.
My studies indicate that males who eliminate odor in this fashion tend not to need worry over contamination of their surroundings by any female odor as well. The mechanism of repulsion has yet to be discerned, but preliminary research indicates it may be due to such preliminary research itself.
I know that when I have tests performed on me, the hotter the woman the more I'm affected. Now excuse me while I hunch forward while the hot nurse takes my blood.
... all gender differences are just social constructs! All the cool people say so!
I'm sure if the mice had been give female monkeys and legos to play with when they were younger, then ... aw, forget it.
The original article says that the rats felt less pain because they were - more- stressed. Not less. The stress was too high for them to feel pain.
Can you please correct this?
So those would be the rats of NIH?

That that is is that that that that is not is not.
The mice are experimenting on us! Someone get to Alpha Centauri quick and get the triplicate forms filled out to prevent the demolition of Earth!
Here is a contradicting article.
Do men stress mice out or not? Why is there polarizing conclusions from the same sources!?!?!?!?

What's wrong with this: measuring "% pain" in an animal that cannot give meaningful feedback (mouse grimace? don't even want to think how they correlated that to pain as I'm sure they tried to) and the defacto assumption that all the experiment's subjects feel pain to the same degree (hint: humans don't all feel pain to the same degree and it is very hard to measure in us even though we can provide very clear feedback to people inflicting pain on us)
Bah! Biology and related fields are not science any more than astrology is.
There are no "first principles' in biology from which to theorize, it's practioners almost uniformly have a poor grasp of basic math and statistics, and their typically, poorly designed 'experiments', usually involve the discomfort, torture, mutilation, or murder of another creature.
Make it so biologists and their ilk are only allowed to experiment on each other. That way the results will be more relevant to humans and the experiments will be fewer and much more carefully designed. Well maybe. Biologists seem to be a sadistic bunch.
"Consensus" in science is _always_ a political construct.
It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.
