While styrofoam may be most commonly associated with disposable coffee cups, meat trays and packaging, prefab home manufacturer Japan Dome House Co., Ltd. uses it to construct easy-to-assemble modular kit homes.

Japan Dome House --

Dubbed the "habitat for the 21st century," the Dome House is an igloo-shaped structure built from snap-together wall sections made of 100% expanded polystyrene foam (styrofoam). It might seem like an odd choice of material for a house, but the company lists a number of advantages that styrofoam has over traditional materials. Unlike wood and metal structures, for example, the styrofoam Dome House does not rust, rot or attract termites. It is also highly resistant to earthquakes and typhoons. In addition, the walls, which are treated with a flame retardant, emit no toxic fumes in a fire.

The styrofoam used in the Dome House's 175-millimeter (7 in) thick walls is significantly denser and stronger than ordinary packing foam. The material has excellent thermal insulation properties, resulting in higher energy efficiency and lower heating and cooling costs.

Construction of the Dome House shell is quick and easy. The prefabricated pieces, which each weigh about 80 kilograms (175 lbs), can be carried by 2 or 3 people and assembled in a few hours. Once the shell is put together, coats of mortar and paint are applied for further protection from the elements. (Watch a short video of the assembly process.)

Measuring 7.7 meters (25 ft) wide and 3.85 meters (13 ft) tall, the basic Dome House has a floor space of 44.2 square meters (475 sq ft). It is possible to construct larger, elongated domes by adding more pieces, and joint units allow multiple domes to be connected into a single structure.

Dome Houses, which are approved by Japan's Land and Transport Ministry, can be erected anywhere in Japan with the proper permit. According to the manufacturer, the versatile structures are suitable for use as hotel rooms, restaurants, freezer rooms, or even as hog farms.

The Aso Farm Land resort village in Kyushu uses about 480 styrofoam domes as lodging, recreational facilities and retail shops.

Whether or not this type of home is truly "perfect for the modern age" as the company suggests, the price is right. Dome House kits start at around 3 million yen (under $30,000), which does not include the cost of transport, assembly, interior construction, etc.

Rare ‘Devil’s Cigar’ fungus discovered in Nara

06 Aug 2008

Chorioactis geaster found in Nara, Japan --

One of the world's rarest fungi, an exotic star-shaped mushroom known to exist at only three locations on Earth, has been discovered in the mountains of Nara prefecture.

The Devil's Cigar (a.k.a. "Texas Star") -- known to botanists as Chorioactis geaster -- had been observed only in central Texas and at two remote locations in Japan prior to the recent discovery in Nara. The peculiar fungus is described as a dark brown cigar-shaped capsule that transforms into a tan-colored star when it splits open to release its spores. It is also one of only a few known fungi that produce an audible hiss when releasing spores.

First reported in 1893 in Austin, Texas, the curious mushroom appears in a limited area of central Texas each year, and until now, the rare sightings in Japan have occurred in forests in Miyazaki and Kochi prefectures. The fungus is included on the red list of threatened species published by Japan's Environment Ministry.

The recent Nara discovery was made by Masakuni Kimura, curator of a natural history museum in the town of Kawakami (Nara prefecture). Kimura first encountered Devil's Cigars in October 2006 while surveying a forest near Kawakami, where he found 12 of them growing from a dead oak tree next to a mountain stream at an elevation of 470 meters (about 1,550 ft). Nearly a year later, in September 2007, he discovered four more of the mushrooms when he returned to the site with Shuichi Kurogi, curator of the Miyazaki Prefectural Museum of Nature and History. Their findings were presented at a recent meeting of the Mycological Society of Japan.

The site of the Nara discovery, like the previous Miyazaki and Kochi sites, is located in a humid forest. At all three sites, the Devil's Cigars were observed growing on dead oak trees near a stream.

Texas Star, the state fungus of Texas?!

In central Texas (which is located at approximately the same latitude as southern Japan), the rare fungus appears during fall and winter, growing from the stumps and dead roots of cedar elm trees.

Tsuyoshi Hosoya, head botanist at Japan's National Science Museum, says, "The DNA of the Devil's Cigar from Miyazaki is consistent with the one from Texas. They are regarded as the same species."

While it is unknown how this exceedingly rare mushroom came to appear only in Japan and central Texas, one intriguing theory suggests that spores from Japan were swept up in an Asian dust cloud and carried across the globe.

19th-century ghost scrolls

01 Aug 2008

Every August, as Japanese spirits return en masse from the otherworld, Tokyo's Zenshoan temple (map) exhibits a spine-chilling collection of 19th-century ghost scroll paintings. Here are a few. (Click the "+" under each image to enlarge.)

Ghost [+] // Sea Monster [+]

"Ghost" by Iijima Koga is a portrait of a floating, kimono-clad female apparition with all the ghastly physical features you hope to find in an undead spirit -- bony hands, a head of stringy hair, and a pained grimace revealing a mouth full of black teeth. "Sea Monster" by Utagawa Hoen depicts an umi-bozu lurking near a boat anchored at shore, with the moon located precisely where the monster's mouth should be.

Kohada Koheiji [+] // Willow and the Moon [+]

Utagawa Kunitoshi's "Kohada Koheiji" shows the main character of a famous Edo-period novel (published 1803) by Santo Kyoden. In the story, after Koheiji is killed by his wife and her lover, his gangly ghost returns to haunt them by peering through the mosquito netting surrounding their bed. (This character is also the subject of ukiyo-e artist Hokusai's famous print "The Ghost of Kohada Koheiji.") "Willow and the Moon" by Koson might at first glance appear as nothing more than a peaceful moonlit scene at the water's edge, but look again -- the moon and clouds form a menacing face in the sky, and the bare willow branches form a scraggly head of hair.

Kaidan Chibusa Enoki: The Ghostly Tale of the Wet Nurse Tree [+]

This painting by Ito Seiu, the godfather of Japanese bondage (kinbaku), depicts a scene from Kaidan Chibusa Enoki, an old horror story in which the ghost of a dead painter returns to protect his baby from his murderer, a wandering samurai who fell in love with his wife while he was away painting. This scroll shows the ghost holding the baby while standing under a waterfall at Juniso (where Tokyo's Shinjuku Chuo Park is now located).

Ghost [+] // Ghost of the Wharf [+]

The subject of "Ghost" by Rinrin is a spirit with an eerie blank stare and gaunt ribs visible under its clothing, and who appears to be melting away. Shibata Zeshin's "Ghost of the Wharf" depicts a feeble-looking apparition relaxing on a pier, casually glancing at something over its shoulder.

Ghost in the Rain [+] // Ghosts of Husband and Wife [+]

Ikeda Ayaoka's "Ghost in the Rain" shows a forlorn-looking female apparition outside in a storm, with flames rising up from where her feet should be. "Ghosts of Husband and Wife" by Otai is a portrait of what appears to be an undead married couple -- a subject rarely seen in ghost scroll paintings. The sinister pair are pictured clutching a human skull. The husband is wearing a traditional Buddhist funerary headdress worn by the dead, and he has blood smeared on his face.

Ghost with a Severed Head [+] // Ghost [+]

Kawakami Togai's "Ghost with a Severed Head" shows a female apparition lovingly cradling a man's decapitated head. The subject of "Ghost" by Gyoshin is a pathetic, emaciated figure with thinning hair and blackened teeth. There seems to be a hint of humor in his expression.

Robot sea bream

25 Jul 2008

Robot sea bream --

Engineers at the University of Kitakyushu have developed an underwater survey robot that looks good enough to eat. "Tai-robot-kun," a 7-kilogram (15.4 lb) robotic sea bream (red snapper) with a silicone body covered in realistically hand-painted scales, features a unique propulsion system that allows it to move its tail and drift silently through the water like a real fish. (Watch a video.)

The robotic fish can swim for an hour on a full battery charge, and it relies on a ballast system similar to those used in submarines to adjust its buoyancy and depth.

Tai-robot-kun's creator, professor Ikuo Yamamoto, says the robot can easily be mass-produced, outfitted with various cameras and sensors, and released into the sea to perform a wide range of oceanographic survey tasks. He adds that because the robot swims silently and looks like a real fish, it would be able to gather data without alarming the creatures it encounters.

Yamamoto and his team are also reportedly developing a robotic manta ray that uses some of the same technology.

Actroid female robot actress --

Actroid DER-2, Kokoro's uncannily lifelike fembot, has made her acting debut in a TV commercial for Kincho's Preshower UV insect repellent/sunscreen spray. Titled "The Woman Who Doesn't Rust," the 15-second commercial spot shows Actroid outdoors at a campground, where she recommends using Preshower because, as a female, her skin is important. After a few squirts of the spray, she cheerily adds, "Surprisingly, I don't rust." (Watch it.)

Fake Mickey Mouse Olympic statues in Beijing

24 Jul 2008

Fake Mickey Mouse Olympic statues in Beijing --

The Yomiuri Online has posted a photo of some new Olympic-themed statues on display in Beijing's financial district. The statues -- which appear about one year after Disney cried copyright infringement in response to a host of knock-off Disney characters at Beijing's Shijingshan Amusement Park -- depict five Mickey Mouse-like characters engaging in Olympic sports. When asked about the resemblance to Mickey, a spokesperson replied, "They have square holes in their ears. They are not copies." The spokesperson suggested the statues are unique because they incorporate the themes of old Chinese coins (the square holes), the year of the rat, the Olympics and the financial district into the design. However, children passing by the statues were seen pointing and saying, "Look! It's Mickey!"

Light-sensitive shape-shifting plastic drives motor

23 Jul 2008

Motor powered by light-activated plasticA research team led by professor Tomiki Ikeda at the Tokyo Institute of Technology has developed what is being called the world's first plastic motor powered solely and directly by light.

Unlike solar-powered motors that use photovoltaic cells to convert light to electric power (and which require wires and batteries to deliver and store the power), this first-of-a-kind motor converts light directly into mechanical energy, thanks to a belt made from a special elastomer whose molecular structure expands or contracts when illuminated, depending on the wavelength of light.

Ikeda began working on the light-activated motor in 2003, after discovering that a plastic compound containing azobenzene would contract when exposed to ultraviolet light and resume its original shape when exposed to visible light. Since then, in addition to working on improving the material's shape-shifting properties, Ikeda's team has been looking at ways to use the material in a motor that converts light directly into motion.

To test whether the material could be used as a mechanical power source, the researchers coated a polyethylene film with the shape-shifting plastic to create a 0.08-millimeter thick belt, which they looped around a pair of wheels measuring 10 millimeters and 3 millimeters in diameter. Then, by shining ultraviolet light on the belt near the smaller wheel and visible light near the larger wheel, the belt snapped into action and began turning the wheels. The larger wheel recorded a top speed of 1 rpm.

According to the researchers, the film demonstrated about 4 times more elastic strength than human muscle, and its strength remained unchanged even after contracting and expanding every 7 seconds for 30 hours.

"The material is still not very efficient at converting light to energy, but it can be improved," says Ikeda, who suggests the shape-shifting plastic can be used in larger-scale applications. He hopes to one day see the material used to power plastic automobiles and other fantastic plastic machines.

The results of the research were published in the July 19 edition of the German chemistry journal Angewandte Chemie.
