The Chemical Behind Catnip's Effects on Cats

CATNIP: EGRESS TO OBLIVION?

- 4aα,7α,7aα-Nepetalactone is the specific isomer responsible for the catnip effect

☠ Firstly, nepetalactone will enter the cat’s nasal tissue, and there it will bind to certain receptors.

☠ These can then trigger particular sensory neurons to signal to other neurons, and eventually the brain; in particular, the ‘olfactory bulb’, a region at the front of the brain responsible for processing smells.

☠ This region then signals other regions of the brain, including the amygdala, responsible for emotional responses to stimuli, and the hypothalamus, responsible for behavioural responses to stimuli.

☠ This results in the observed response in cats – a response that is actually similar to their response to natural sex pheromones.

☠ The effect of catnip lasts for around ten minutes, and afterwards there will be a refractory period of around an hour where the cat will remain unaffected.

☠ Interestingly, not all cats are affected by catnip; the response is genetic, and autosomal dominant, which means if one parent passes on the gene, then the offspring will inherit the response.

Immunotherapy FTW! 
First peanuts, now eggs. Doctors have reversed allergies in some children and teens by giving them tiny daily doses of problem foods, gradually training their immune systems to accept them.In the best test of this yet, about a dozen kids were able to overcome allergies to eggs, one of the most...

So awesome.
 
I've seen some cleverly carved pumpkins before, but these amazing pumpkin carvings by Ray Villafane elevates tradition into the realm of art. Born into a poor farming family, he found himself having to whittle his own toys out of wood for his amusement. He eventually had to turn to pumpkins as his medium of choice when even that became too exorbitant. Luckily his early trials also honed his artistic skills to the point where he's able to bring out shockingly realistic scenes and faces out of mere pumpkins. Jump past the break to see more examples of his wonderful pumpkin art, just make sure you haven't had lunch yet. Some of them are too realistic ;)
