Fire-Fighting Robot


(YouTube Link)


The Fire Spy Robot, developed by the South Korean firm Hoya Robot, can be thrown into a burning building, roll through fire, take pictures, and inform firefighters outside of the conditions inside. In addition to reconnaissance duties, it can tow a water hose and spray the fire:

The little two-wheeled robot can roam through the blaze spraying water from a fire hose and looking for trapped people. Its onboard light and camera helps firefighters pin-point people before they enter the building themselves. The robot also gives them enough information to decide on the safe routes, and quickly develop a rescue plan.

The Firefighters Assistance Robot is a small device resembling a miniature tank and measuring just 12.5 cm in diameter and weighing 2 kg. It can travel at 1 foot per second and withstand a fall of over six feet. It can also survive temperatures as high as 160 C (320 F). The operating time of the robot inside a burning structure is up to 30 minutes.

Turning a Staircase into a Piano


(YouTube Link)


This Volkswagen commercial is about one effort to get people to take the stairs instead of the escalator (presumably for the exercise). The company turned a staircase at a Stockholm subway station into a piano and videotaped how travelers responded.

A Variable Horse-Drawn Trainer

For centuries, people have trained race horses by making them pull heavy weights. But after Mehmet Kurt lost a horse due to overtraining, he decided to create a training vehicle that was safer and could be adjusted for individual training needs. Natalie Avon writes in Popular Science:

The horse isn’t pulling the four-and-a-half-ton, $427,000 vehicle. Rather, the vehicle keeps pace with the animal, and trainers fit the horse with equipment such as an electrocardiogram machine, oxygen masks and movement sensors to monitor its performance. They can then subtly regulate the horse’s speed for optimal training.

The History of the Barcode



Google's doodle for today is a barcode, in honor of the 57th anniversary of its invention. Nick Collins writes in The Daily Telegraph about the history of this label:

Granted to American inventors Norman Joseph Woodland and Bernard Silver three years after it was filed, patent number 2,612,994 was for a pattern of concentric circles, rather than the set of straight lines used today.

Their research began in 1948 after Mr Silver, a graduate student at the Drexel Institute of Technology in Philadelphia, overheard a local food chain boss asking one of the institute's deans to design a system for reading product data automatically.

Mr Silver and Mr Woodland, a fellow graduate student and teacher at Drexel, first tried using patterns of ink that glowed under ultraviolet light, but it proved too expensive and unreliable.

Mr Woodland then came up with the linear bar code, and later replaced the lines with circles so that they could be scanned from any angle. The pair patented their “bull’s eye” design the next year.


The barcode became widely used in UPC (universal price product code) format, and the first UPC-labeled item scanned by a reader was a packet of Wrigley's chewing gum at a grocery store in Troy, Ohio in 1974.

Physicist Proposes Using Cannon to Fire Payloads into Space

Physicist John Hunter has proposed the construction of a 1.1-kilometer-long cannon that could fire a 450 kg payload into orbit. David Shiga writes in New Scientist:

The gun is based on a smaller device Hunter helped to build in the 1990s while at the Lawrence Livermore National Laboratory (LLNL) in California. With a barrel 47 metres long, it used compressed hydrogen gas to fire projectiles weighing a few kilograms at speeds of up to 3 kilometres per second.

Now Hunter and two other ex-LLNL scientists have set up a company called Quicklaunch, based in San Diego, California, to create a more powerful version of the gun.

At the Space Investment Summit in Boston last week, Hunter described a design for a 1.1-kilometre-long gun that he says could launch 450-kilogram payloads at 6 kilometres per second. A small rocket engine would then boost the projectile into low-Earth orbit.

Talking Piano


(YouTube Link)


Austrian composer Peter Ablinger digitized a recording of a child speaking and then programmed a mechanical piano to replicate the sounds. The video above is in German, but Hack a Day has provided a translation:

I break down this phonography, meaning a recording of something the voice, in this case -, in individual pixels, one can say. And if I have the possibility of a rendering in a fairly high resolution (and that I only get with a mechanical piano), then I in fact restore some kind of continuity. Therefore, with a little practice, or help or subtitling, we actually can hear a human voice in a piano sound.


The content of the speech is taken from the Proclamation of the European Environmental Criminal Court at World Venice Forum 2009.

A 'Vaccine' for Cocaine

Katherine Harmon writes in Scientific American that pharmacology researchers are developing a drug that could diminish the pleasurable effects of cocaine. Taking the drug might help addicts detoxify with greater success:

The vaccine itself does not destroy cocaine molecules, rather it induces antibodies that bind to it, making the opiate lose its ability to pass through the blood–brain barrier—and thus unable to trigger a high.

To test the vaccine's effectiveness in humans, researchers (with some help and financial backing from Celtic Pharma) enlisted 94 subjects who had enrolled in a methadone treatment program for opiate addiction—and who also regularly used cocaine—for a placebo-controlled, double-blind study. (They decided on this group because methadone programs historically have better retention rates than programs for cocaine abuse only.) One group received a placebo, another a low dosage of vaccine, whereas a third was administered a high dosage over a series of 12 weeks with five total injections.

More than half of the subjects in the high-dosage group (53 percent) appeared to have laid off the cocaine for more than half of the trial period, the researchers report after tracking traces of the drug in urine samples collected three times a week. Just less than a quarter of subjects with the low dosage had the same track record, according to the results published online yesterday in the Archives of General Psychiatry. A drop in cocaine usage across all groups may also be attributed to a curb in opiate drug consumption from the methadone treatment.

A Picture of a Sunspot

The image above is a computer-generated model of what a 3,700-mile wide sunspot looks like. It was created by scientists at the National Center for Atmospheric Research in Boulder, Colorado for their ongoing efforts to understand the physics of sunspots:

"This is the first time we have a model of an entire sunspot," says lead author Matthias Rempel, a scientist at NCAR's High Altitude Observatory. "If you want to understand all the drivers of Earth's atmospheric system, you have to understand how sunspots emerge and evolve. Our simulations will advance research into the inner workings of the Sun as well as connections between solar output and Earth's atmosphere."[...]

The new computer models capture pairs of sunspots with opposite polarity. In striking detail, they reveal the dark central region, or umbra, with brighter umbral dots, as well as webs of elongated narrow filaments with flows of mass streaming away from the spots in the outer penumbral regions. They also capture the convective flow and movement of energy that underlie the sunspots, and that are not directly detectable by instruments.

The models suggest that the magnetic fields within sunspots need to be inclined in certain directions in order to create such complex structures. The authors conclude that there is a unified physical explanation for the structure of sunspots in umbra and penumbra that is the consequence of convection in a magnetic field with varying properties.

Monty Python's 40th Birthday


(YouTube Link)


Monty Python's Flying Circus debuted 40 years ago today. Marc Lee writes in The Daily Telegraph about the origins and development of the troupe:

Four decades on, the image of John Cleese’s increasingly hysterical pet-shop customer — pacamac buttoned up, hair plastered down, vowels strangulated — remains one of the most memorable in television history. No other comedy series has seared itself into the national consciousness quite like Monty Python’s Flying Circus.

And, if the sketches were ever to be placed in order of popularity, Cleese’s confrontation with the chirpily evasive Michael Palin — the shopkeeper who simply will not admit that the inert “Norwegian blue” is dead — would undoubtedly come top. Indeed, when Channel 4 counted down the 50 greatest comedy moments, the “Dead Parrot” sketch perched at number two, just below the, frankly, far inferior “Lou and Andy at the swimming pool” sketch from Little Britain.


The video above is of the classic sketch "Argument Clinic" -- my favorite. What's your favorite Monty Python sketch?

American Gothic Parodies is a compendium of images based on Grant Wood's iconic painting "American Gothic." It was assembled by an illustrator named McGlinch from his grandmother's collection. That's all of the information that I can find about him, other than that he is a contributor a blog called Bad Spock Drawings, which is also a hoot.

Donald Duck Transformer



Andrew Dobrow of GearFuse worries that we could see more monstrosities like this if Disney buys Hasbro as well as Marvel Comics. The "Donald Duck Holiday Vehicle" is on sale (but backordered) from the Japanese company Takara Tomy for about $40. Most worrisome of all -- it bears neither the Autobot nor Decepticon icon.
