This year, the Burning Man Organization has set out rules for drone operation on the playa, developed in concert with drone-hobbyist/burners who attended a summit at BMOHQ on July 17. The rules include a common-sense safety code, parameters on where/when/who can be videoed; fire safety rules; spectrum management procedures; and guidance on elevation and wind.

Experts from the Danish National History Museum have warned that pacus -- a relative of the piranha -- have been spotted in the Danish/Swedish Øresund channel. The pacu has been known to bite swimmers, and have been known to attack men's testicles, because "testicles sit nicely in their mouth." So men are being cautioned to avoid nude swimming in the channel, though the museum's Henrik Carl stresses that the risk is not very high, in the grand scheme of things: "You're more likely to drown than get your nuts bitten off."

Mentalist and conjurer Derren Brown got a hell of a shock during his Saturday night show: a woman pushed her husband off a 45' balcony "for a joke," sending him over the edge. He caught hold of a light-rig about halfway down and was pulled to safety.

An Asiana Airlines 777 from Seoul, Korea crash-landed at San Francisco International Airport last night. Two were killed, ten were critically injured, 181 others were taken to hospital.
David Eun, whose Twitter biography includes "frequent flier," was aboard the plane and tweeted a photo of the wreck as he was evacuated.
This Reddit thread contains a lot of great, breaking information, including audio from the SFO air traffic control during and after the crash, and eyewitness accounts from SFO and from diverted fliers who were landed elsewhere (SFO is closed until further notice).
It's not clear what caused the crash. Forbes has some early analysis of the debris field based on aerial photos. A prominent theory cited in several news reports is that the tail of the 777 caught the seawall and ripped free (
this also suggests that the two fatalities were flight attendants in the rear jumpseats). Update: An Asiana Airlines rep has confirmed that the two dead were passengers; specifically, teenagers from China.
Drowning, in real life, doesn't look or sound the way it does on TV. It's not loud. It's not thrashy. And it can happen just a few feet away from you without you even noticing. At Slate, Mario Vittone explains the Instinctive Drowning Response
— a physiological knee-jerk reaction that pretty much prevents all the signs and signals most of us look for in order to identify a person in the water who needs help.
Last Friday, a tornado near El Reno, Oklahoma killed scientist Tim Samaras, as well as his son and a colleague. The three were tracking the storm in a vehicle — storm chasing, if you will — as part of their ongoing efforts to deploy probes that could capture high-resolution video from inside a tornado. (Samaras' team was one of many practicing a type of science that can basically be described as Twister in real life.) Chasing storms was an important part of what Samaras did. National Geographic reports that tornadoes only developed in roughly two of every 10 storms Samaras tracked, and the probes were only useful in a fraction of the tornadoes they were deployed in.
Samaras' death is tragic, but he wasn't some untrained yahoo out running around on county roads in a tornado for fun. He was there to do a job; a job that would, eventually, help other people survive. That said, if a situation kills experts, you probably don't want to be that untrained person trying to navigate it on your own.
Which brings us to a key point. After a handful of people who survived the Moore tornado credited their survival to driving away from it, people in Oklahoma City apparently responded to Friday's storms by trying to do the same thing. For some, it worked. But others were killed or injured when traffic on highways in the tornado's path ground to a complete halt, clogged with cars full of people who were (either accidentally or intentionally) trying to flee the storm instead of hide from it.

Vincent sez, "Our high school film class from Oak Park High in Winnipeg, Manitoba, Canada made this zombie-themed PSA to spread the message about a worker's right to refuse unsafe work.
It's a big issue. In Canada, in 2010, 1014 workplace deaths were recorded in Canada - that's almost three deaths every day! Between 1993 to 2010, 16,143 people lost their lives due to work-related causes in Canada.
A 2003 survey showed that compared with other developed countries of the OECD, Canada isn't doing too well. Of the 29 developed nations 24 had significantly lower workplace death rates than Canada. Using the factor of deaths/100,000 workers, Canada was only safer on average than Korea (29 deaths), Turkey (20.6 deaths), Mexico (12.0 deaths), Portugal (8.7 deaths) and then Canada with 6.1 deaths per 100,000 workers.*
Our class used humour because we thought it would be an effective way to create a memorable message. Our PSA won first place in the Manitoba Safe Work video contest, and it is now competing to be the top Canadian video.
You may remember our school, which has made other popular videos that you have featured on Boing Boing, including 'Jedi High,' 'Anti-Racism Girl,' and 'The Pink Shirt.'"
The power of suggestion, your own expectations, and even your emotions can cause your body to move without you actively telling it to. This weird phenomenon is called the ideomotor effect
. It's what makes ouija boards work and it's the mechanism behind $60,000 bomb-detecting devices that an American company was recently caught selling to the Iraqi government
. Needless to say, the devices did not actually detect bombs.
M Otis Beard sez, "You don't often hear about the deaths that happen at Burning Man. Here is an overview
that just might save your life." Be that as it may, Black Rock City has extraordinarily low mortality compared to comparably populated/sized areas in the USA.
Fertilizer can explode*. We all know that. It was a key ingredient in the bomb that destroyed Oklahoma City’s Alfred P.

California Occupational Safety and Health (OSHA) has served notice on Disneyland over three attractions, which led to their shut-down yesterday. In 2006, Disney agreed to make changes to the staff areas at the park, and the OSHA notice apparently related to lack of progress on these promises.
The citations were related a 2006 agreement to make improvements and to inspections following recent accidents such as the man who was seriously injured while cleaning the outside of Space Mountain. The findings include simple failures like not having a charged fire extinguisher and more serious ones like failure to protect employees from unsafe ladders or lack of railings preventing a fall hazard. Serious fines of up to $70,000 for each infraction could be levied if Disneyland does not comply immediately with the requests (although appeal is also an option). Total penalties for just the Space Mountain citations could reach over $230,000.
These are the same sort of hazards that forced Disneyland to close Alice in Wonderland until temporary scaffolding could be erected with guardrails. The park still hasn’t made permanent fixes there.
There were a lot of violations listed in the citation, here are a few of those listed as Willful Serious:
“Disneyland Resort failed to correct the unsafe work practice of employees of both Disneyland Resort and HSG Inc. accessing upper exterior platform of a building (Space Mountain) to change lights, and perform other maintenance tasks without the protection of guardrails or personal fall protection...”

It's been a good week for pedantry
. In a guest blog post at Scientific American, Kyle Hill discusses the durability of spaceship windows — both in the real world, and in Joss Whedon's movie Serenity
. Spaceship windows have to be incredibly tough, because even tiny chips of paint become dangerous projectiles in space. But how would they stand up to frontal attack by a spear?
Physics has the answers.
