I'm probably older than you.
So, the way we experience…pretty much everything is via proteins and ion channels. Very basically…there are proteins that are designed to sense certain things….the presence of sugar, whether they’ve been struck by light, the concentration of CO2 in the blood. When they sense those things, they open an ion channel changing the electrical charge of the cell, which then get transferred through the nervous system to the brain where that area of the brain is like “Cool…we’ve got sugar…or light…or too much CO2 in the blood.”Well, sometimes these proteins can be fooled. A chemical will, just by chance (or by natural selection) be able to bind with that protein and cause that whole cascade to occur without the real stimulus. This is what happens with menthol in mint and capsaicin in peppers. Those chemicals bind to the cold / hot receptors respectively, fooling your body into thinking that something cold / hot is happening in your mouth. Pretty cool.-Hank

That’s right! None of these cops are wearing badges or name tags! I wonder why… seems like it’d be important to wear those, since it’s even illegal not to in other states…
This is actually illegal in all states. A police officer must be marked as such with name and badge at all times unless their jurisdiction states otherwise (such as an undercover officer), and even when not wearing a badge, the officer must have the badge accessible at all times and must show the badge in order to make an arrest. Name tags are not required as long as a badge is available because the badge has the officer number on it.
This has really been bothering me. The police in Ferguson are breaking the law by concealing their identities. Everyone knows this, it’s been going on for ten days, and it appears that nobody is doing anything about it.
The police are clearly and systematically violating the first amendment rights of the press, and they are getting away with it. This has been happening for days, and nobody appears to be doing anything about it.
A police officer pointed a rifle at a journalist and told him to fuck off *while he was being filmed, so he’s easily identifiable by his superiors*, and that police officer still has a job.
I know that not all cops are bad (or even most cops), but there are clearly bad cops in Ferguson, and they’re acting with complete impunity. I don’t understand why those cops aren’t being taken off the scene, and why a higher (possibly federal) authority isn’t coming in to address these things.

This is the perfect visual metaphor for heterosexuality.
I really can’t get over what a good metaphor this is.
they could’ve just made them square but that’d probably be too gay
but then how would the dude be in the lady’s space, expropriating her value? D:
Guys, this is obviously literally meant as a metaphor for the depressingly common dynamics of most heterosexual relationships, and indeed of society in general.
the ‘hers’ cup only appears to have a normal shape when paired with the ‘his’ cup. on its own, the cup would appear to be missing something. why is heterosexuality so terrible?
"I’m sick of how bisexuality is erased in LGBT spaces. I get really nervous before any LGBT event, especially Pride. I feel incredibly sad and hopeless when gay and lesbian people call me insulting names. If gay and lesbian people don’t understand me – Continue reading Prejudice at Pride at Empathize This
This just punched me in the heart.
It’s hard to admit that this happens in our community, but it definitely does. Speaking out is the only way it will stop.
