Ever wonder how a Jellyfish “stings”? Turns out, it’s actually like a Needle. Check out this awesome graphic that Emily Weddle created from the latest episode of Smarter Every Day.
As you can see in the graphic, a Jellyfish actually stings you with needles. The process in the photo spans the time of approximately 20 milliseconds. If you watch the video I incorporate timing data so you can perform measurements.
What’s so cool about this is scientists don’t really understand HOW they nematocyst fire. They’re pretty confident that they’re triggered by mechancial contact on the outside, of the tentacle… but they’re NOT sure how the stinger “inflates”. Dr. Seymour thinks it’s too fast to be osmotic. There’s obviously a channel somehow that opens and creates flow and pressure into the organelle. I bet it’s some kind of REALLY quick chemical process.
I think we’re going to call graphics like this “Smarter Every Day InfoGifs”.
It’s still Shark Week! Most sharks are pretty terrifying (perhaps it’s their nasty habit of biting people’s limbs off…) but they need our empathy too. “We’re killing over 100 million sharks every single year,” photographer Brian Skerry says in his talk from the Mission Blue Voyage. “I didn’t want to continue to portray sharks as monsters.” That’s a tough sell with their hammerhead noses and giant teeth, but hey, these sharks turned out to be pretty friendly.
Square, the payments startup from Twitter cofounder Jack Dorsey, has prototyped a Square credit card. The plastic card is all black, and save for the card holder’s name emblazoned on the face, features no logos—not even Square’s. Over the past year, multiple sources indicate Square employees have been carrying the card—seen here below, partially blurred to protect the card holder’s identity—around in their wallets.
However, despite buzz about the potential of a Square credit card, other company sources indicate the project was recently killed.
Details of the rumored prototype came to light during reporting for Fast Company's profile of Square, published this week. As Square seeks to unearth new sources of revenue beyond its core business of payments processing, the company has launched a slew of new products, including Square Market, Cash, Feedback, Invoices, Capital, Dashboard, and on Monday, August 11, Appointments. Some insiders expected the Square credit card would be a promising addition to the mix, potentially opening the company up to a swath of lucrative consumer loyalty and rewards services. But after pressing the company multiple times about the project, Square finally confirmed that it’s not launching a credit card. Or, should we say, the company is no longer launching one. And the reason why highlights the difficulties Square faces in the immensely complex financial space.

Cotton candy is so sweet and yummy that we’ve always happily eaten it without paying any attention to the fact that it usually looks like the end of a giant cotton swab. That has all changed since we first watched this hypnotic video in which a skilled street vendor in Ciqikou, Chongqing, China creates servings of spun sugar that look like enormous, colourful flowers.
Great big, fluffy flowers of sugary awesomeness.

Possibly using a safe zone program of some sort, that allows youth to speak to a counselor and work through their feelings about their gender and sexuality. It could also be a safe place for children to come out to their parents. So they are less likely to grow up with repressed feelings of inadequacy and self hatred.
