Scientists have determined that humans can detect ten basic smells:

Welcome to Thatz Not Okay, a regular column in which I school inquiring readers on what is and is not okay. Please send your questions to caity.weaver@gawker.com with the subject "Thatz Not Okay."

If you know you have a poor sense of smell, you'd better stop reverse-bragging that little weakness into conversation to make yourself seem "accessible" to fans; researchers in Australia are claiming a poor sense of smell could be linked to psychopathy. (Also, stop acting like you have "fans," you fucking psychopath.)

Lady Gaga was forced to release her own sexy Instagrammed images of her (heretofore closely guarded) debut fragrance black fluid "Fame" on Twitter today, following the leak of a low quality picture in which the bottle looked totally shitty that took place a few days ago.

The following thoughts have flickered through my mind in rapid succession at least once a week for as long as I have worked on the fourth floor of Gawker Media's offices.

Old people do not stink, scientists found today. A large-scale study of people who wore things in their armpits and then had other people smell those things concluded that "the underarm odor of 75-to-95-year-olds was judged to be less intense and far more pleasant than the scent of either young or middle-aged adults."

Men are gross, stinky pigs, right? Right! But did you ever think your man stank because he has an STD? Russian scientists just discovered our nose knows who not to sleep with.

Here's a trailer for Robert Rodriguez's unnecessary Spy Kids 4: All the Time in the World. 3D is real popular, so the movie's in 3D. But it's also the fourth movie, so the "3" in "3D" just won't do. So they've added a fourth "dimension": Smell!

In Style has an innovative new plan for saving print media: Their annual "101 Reasons to Smile This Summer" features five scratch-and-sniff scents. Editor Ariel Foxman explains the vaguely infantilizing concept:

Haven't you always wanted to party at the Playboy Mansion? You probably can! Just know there is "a powerful whiff of urine" mingling with a "general scent of decay," according to Playboy founder Hugh Hefner's ex Izabella St James.

Attention, ladies: Feeling insecure about... you-know-what?You might want to watch this infomercial for "Tajazzle" a three-step system to help you "Stay Dry And Smell Fresh Where It Gets Hot." Dry and "fresh"-smelling! Just the way men like it. [via]

Flowery New York Times perfume critic Chandler Burr is stepping down from that job to become the "curator of olfactory art" at the Museum of Arts and Design. Is this the end of an era of scent-based pretension?

According to a new study, overweight people have "far heightened" senses of smell for food compared with people who aren't overweight—in particular after eating a full meal. Science: Making the mean joke so you don't have to!

Fact: New Jersey smells terrible. So officials from the Middlesex County Landfill have devised a plan to neutralize putrid methane gas odors—spray hundreds of gallons of a citrus-scented air freshener from a truck. Good luck with that!

In the wake of Steven Slater immortalizing himself with spectacular display of flight attendant rebellion, we call our attention to another act of mid-flight attrition: "cropdusting," when flight attendants walk down an airplane aisle and fart in seated passengers' faces.

U Street in Washington D.C. was covered in "a greasy mess that smelled like vomit" on Wednesday. Was it the sickening, bilious waste of the United States Senate, come to life? No, it was just "used restaurant oil." [WTOP]

A "gag-inducing smell," believed to be a byproduct of the nearby oil spill, is hanging over New Orleans. Think "if a bus was in front of you blowing out exhaust fumes right in your face." Laissez le mauvaise odeur rouler!
