Yeah, I think nobody has ever isolated a specific chemical that humans produce that you could describe as a pheromone. But there have been studies that suggest that there is more to smell, than just, you know, the the odour.

At any rate, not washing your armpits/pubes probably not the best way to attract a mate. (Altho... horses for courses...)

Pheromones? I've seen quite a few of sciency clips from credible sources that say humans haven't been observed to have any pheromones.

Agreed. I think that's the first example of hunting with pheromones that I've heard of. And being able to customize them for different species is almost beyond belief.

The Redback was interesting but that pheromone spider is just god damn evil.

It's no wonder she can laze about all day, as long as moths exist she's basically guaranteed food. On top of that, it looks like bird shit so nothing wants to eat it? That's some serious evolution!

Interesting. I think a Civilisation type game would be more interesting as ants tend to live as a colony rather than individuals.
I wonder if he'll add any pheromone mechanics? Being a scout that creates safe trails to food sources would be an interesting game type.

Found the video more enjoyable once i read this:

Both green olives (Olea europaea) and Pimentos (Capsicum annuum) contain isoprenoids that are structurally similar to the methylcyclopentane monoterpene nepetalactone, which is responsible for binding to receptors in you cat's vomeronasal organ and consequently the mind-altering effect your cat experiences.
These compounds are not unusual, although thie configuration varies widely between plant species.
These compounds resemble pheromones, and as such some of them function as a natural mock-pheromone pest repellents for the plant, which is likely how such high levels of these constituents within a plants' essential oils evolved.
The vomeronasal organ is what your cat (and most other animals with the exception of humans, although there is a small indented area and partial nerve channel where it would be, left over from our evolution) uses to sense pheromones, and is where the nepetalactone in catnip stimulates pheromone receptors resulting in space-kitty.

TL;DR - it is likely that either the green olives or pimentos have a chemical in their essential oil that is similar enough to the active chemical in catnip to have a similar effect on the same receptors in the part of kitty's nose that are responsible for catnip getting her high.

Bumble bees are not carnivorous, accordingly it would have no reason to deploy a sting other than defensively. As it was not under threat itself, the only conclusion can be that it came to the defense of the trapped bee.

The only real question is the mechanism used to communicate the threat and I would guess that it's pheromone based.

Awww!? That guy must have some kitty-cat pheromones in his chemical signature...Maybe kitty was a rescue kitten and this guys' the #1 hero??

Actually, these are androconial organs, not it's "penis". The structure is used in the dispersal of pheromones which attract females. The hairs increase the surface area, speeding evaporation of the pheromones into the air.

Somebody switched his regular cologne with deer pheromones, let's see if he can tell the difference.

Fred Rogers was an incredible piece of work-My own disgust/boredom with broadcast media would subside some what while tuning-in to his show-He had boldness and confidence to accompany his disengaging calm that stimulated neurotransmitters like uncut drugs or pheromones-

Oh, had a major kid-crush on Lady Aberlin....

Wonder how stinky a lion would be....Sure looks like a whole-lotta kitty pee essence and male feline pheromones in a package that size...
