Disney's "Envelope Of Protection"

"How Disney Ensures That Your Arms Won't Get Torn Off On Rides":
You may be told to keep your arms and legs in the vehicle at all times when you get on a roller coaster or ride, but it's unlikely that you'd actually lose a limb if you disobeyed thanks to something called the 'envelope of protection'...

Disney uses an "envelope of protection" when testing their rides to ensure that no one could possibly reach out and hit anything. This sounds like a spell you could cast in Dungeons & Dragons, but it's actually pretty simple. They test the ride using a special vehicle with a disk attached that has a number of spindles fixed all around it. These spindles act as a person's hypothetical limbs, and they're much longer than a human's reach could possibly be... 
Interestingly, "selfie sticks" can extent beyond the "envelope of protection" and cause serious problems. Hence, Disney has banned them from the park.

The Calculator And The Tablet

"Casio released a calculator and Amazon released a tablet within 24 hours of each other this week. That alone is unremarkable. One costs $220, the other costs $50. That, too, wouldn’t raise many eyebrows, until you realize which is which..." (Via Gus Van Horn.)

Hsieh Forbes Column: Bad Science Reporting

My latest Forbes piece is now out: "How To Protect Yourself Against Bad Science Reporting".

I discuss some sources of error and bias that lead to bad science reporting, including:
1) Many publicly reported science results are still provisional
2) Beware of sloppy statistics
3) Beware of the bias towards positive dramatic results
This latest piece is relatively non-political. But it is uncompromisingly pro-bacon.

For more details, read the full text of "How To Protect Yourself Against Bad Science Reporting".

Drones Build Rope Bridge

"Watch these drones build a rope bridge":
One of the big selling points of drones is that they can get to areas that aren't exactly safe or accessible by humans. That's why watching quadrocopters assembling a rope bridge that's sturdy enough for a person to walk across is so damned awesome -- it immediately calls to mind a real-world use scenario that probably all of us can relate to.

The video below was filmed at RTH Zurich Flying Machine Arena in Switzerland, and, according to the YouTube description, aside from the scaffolding on either side of the bridge, the structure is "entirely realized by flying machines." Every knot and braid in the 7.4 meter (just over 24 feet) bridge was tied by the UAVs using Dyneema rope. As Robohub tells it, the material has a low weight-to-strength ratio that makes it pretty great for aerial construction uses...

In a further alarming problem, the security protections on many of the older machines are inadequate, leaving them vulnerable to hacker attacks...

Zero-G Whisky Glass

NYT: "A Glass for Enjoying a Sip of Whisky While Floating in Space"
The bottom of the bulbous glass, made of gold-plated stainless steel, contains a spiral ring for a reservoir of whisky to cling to. Through a phenomenon known as capillary action, first observed by Leonardo da Vinci, the whisky is drawn upward through a helical channel within the side of the glass to a mouthpiece at the rim for a space traveler to drink.

Two budding Seattle scientists are making a name for themselves after sending a homemade spacecraft 78,000 feet above the Earth's surface on Saturday. Sisters Rebecca and Kimberly Yeung are 10 and 8 years old.

In a video posted to YouTube by their father, Winston Yeung, the girls explain their experiment, which they called the Loki Lego Launcher - after their cat. A cutout photo of Loki hitched a ride on the craft, along with a LEGO figurine of R2-D2.

Market For Perfect Poop

CNN: "One man's poop is another's medicine".

Donors who qualify can earn $40 per sample of "perfect poop", to be used for fecal transplantation to treat patients with C. difficile infection:
To donate, Eric had to pass a 109-point clinical assessment. There is a laundry list of factors that would disqualify a donor: obesity, illicit drug use, antibiotic use, travel to regions with high risk of contracting diseases, even recent tattoos. His stools and blood also had to clear a battery of laboratory screenings to make sure he didn't have any infections. 

After all that screening, only 3% of prospective donors are healthy enough to give. "I had no idea," he says about his poop. "It turns out that it's fairly close to perfect."

And that, unlike most people's poop, makes Eric's worth money. OpenBiome pays its 22 active donors $40 per sample. They're encouraged to donate often, every day if they can. Eric has earned about $1,000.
The poop also has to have the acceptable texture, either types 3, 4, or 5, on the Bristol Stool Chart:
