In 1994, Cynsa, a member of the pioneering online community The WELL, thrilled us with her Rectal Foreign Bodies page all about the weird things people have put in their butts as reported by medical professionals tasked with removing the items. Barry Petchesky has continued this important online endeavor with his series of posts "chronicling our country's cavity misadventures." He posted his latest list, drawing from the U.S. Consumer Product Safety Commission’s database of emergency room visits, over at VICE in a delightful article titled "What Did We Get Stuck in Our Rectums Last Year?." Here is a sample:

• “PATIENT STATES HE STATES SLIPPED IN THE SHOWER AND LANDED ON A METAL AIR FRESHENER CAN AND IT WENT INTO RECTUM” • FOLDING KNIFE • PLASTIC TOY, “ABOUT 6 INCHES LONG” • TOOTHPICK • MATTRESS FOAM • TWO RAZOR BLADES • COAT HANGER, “PATIENT UNSURE HOW IT GOT THERE” • COINS • LIGHT BULB APPLE SAUCE CAN • “ACCIDENTALLY GOT A DILDO LODGED IN RECTUM & CUT THE END OF THE DILDO OFF” • CHRISTMAS ORNAMENT

Isaac Johnson, 14, of Bloomington, Minnesota, has the world's largest mouth gape. Johnson's 3.67 inch pie hole was recently confirmed to be .21 inches large larger than the gape of the previous record holder, a German fellow named Bernd Schmidt.

According to Guinness World Records, Johnson "can fit objects like a baseball and the bottom of a 20 oz soda bottle into his gape."

From the 1950s until the 1980s, Randy and Dotti Smith supplied a line of fantastic cast sculptures sold in Disney theme-park gift shops, especially a line of skulls sold in shops associated with the Haunted Mansion and Pirates of the Caribbean rides; these Randotti skulls haven't been sold in decades, you can still find used ones (at high prices) online, as Boing Boing pal and fabulous illustrator Coop discovered when he sourced an impressive collection of Randotti sculpts.

New, high-res 3D images of human embryos show a variety of muscles that were "present in our ancestors but normally absent from the adult human." For example, there are hand muscles that temporarily appear in human embryos but usually disappear before birth. According to the researchers, our human ancestors lost those "muscles from the back of the hand about 250 million years ago as mammals and reptiles split on the evolutionary tree." From Science News:

These appearing and disappearing, or atavistic, muscles are remnants of evolution, says biologist Rui Diogo of Howard University in Washington, D.C. Such atavistic muscles are built as a base from which to start paring down to the final set of muscles that people are born with, he says. “Losing and specializing, that’s what happens in human evolution.”

Other animals have kept some of those muscles. Adult chimpanzees and human embryos have epitrochleoanconeus muscles in their forearms, but most adult humans don’t. Human’s mammalian ancestors also lost dorsometacarpales muscles from the back of the hand about 250 million years ago as mammals and reptiles split on the evolutionary tree. Lizards still have those muscles, and they appear in human embryos, but then are lost or fuse with other muscles during development and aren’t found in most adults.

More than 100 hours of MIR scanning has generated an image of a whole human brain with unprecedented level of detail. Massachusetts General Hospital researchers and their colleagues used a 7 Tesla MRI machine, recently approved by the FDA, to scan the donated brain from a 58-year-old-woman. The image shows detail down to .1 millimeter. From Science News:

Before the scan began, researchers built a custom spheroid case of urethane that held the brain still and allowed interfering air bubbles to escape. Sturdily encased, the brain then went into a powerful MRI machine called a 7 Tesla, or 7T, and stayed there for almost five days of scanning...

Researchers can’t get the same kind of resolution on brains of living people. For starters, people couldn’t tolerate a 100-hour scan. And even tiny movements, such as those that come from breathing and blood flow, would blur the images...

These (new kinds of) detailed brain images could hold clues for researchers trying to pinpoint hard-to-see brain abnormalities involved in disorders such as comas and psychiatric conditions such as depression.

"Titties" is a stupid word. It's so stupid and gross that some millennials are replacing it with even more ridiculous words like "tiddies" or "titays." Brilliantly funny MEL Magazine editor Alana Hope Levinson explores how "The Extremely Online are destroying language — one tiddy (or tity) at a time." From MEL:

I first started thinking about this when columnist merritt k wrote about the state of fake boobs and tried to get away with “tity” — with one “t” — throughout the entire draft. I thought it was a typo, but I was astounded to learn that merritt is on a one-woman crusade to make “tity” both the singular and plural.

Still, I thought merritt was a lone tity weirdo until I encountered “tiddies” in writer and designer Robyn Kanner’s draft on trolling Instagram’s nudity policy. “Tiddies” — apparently also the choice spelling of my bible, Jezebel — first appeared when Kanner was describing a scene in Garden State where Method Man asks Zach Braff, Peter Sarsgaard and Natalie Portman if they “saw some titties” at a strip club. In this case, Kanner was using the double d (lol) as a pronunciation spelling common in slang cause she thinks it “has more swagger.” “Titties with a ‘t’ is nice, but it just sounds like college boys talking about boobs,” she says. “Tiddies is ‘we are older, but we are recognizing we are making a joke about boobs.’” Because “titties” is so ridiculous, making it even more so somehow neutralizes the effect with comedy — or at least gives you some ironic distance.
