Ig Nobel Prize: Panda poo power

02 Oct 2009

Researchers from Kitasato University in Tokyo have been awarded this year's Ig Nobel Biology Prize for demonstrating a method to reduce kitchen waste by more than 90% by using bacteria derived from Giant Panda excrement.

Giant Panda --

Professor Fumiaki Taguchi, who shares the prize with fellow researchers Song Guofu and Zhang Guanglei (both from the Kitasato University Graduate School of Medical Sciences), began the project in 1998 after suspecting panda feces must contain bacteria capable of breaking down even the hardiest of foods because of the bear's vast consumption of bamboo.

Found in only a handful of areas in mainland China, the Giant Panda has a diet which is 99% bamboo. The rare and exotic animal, which can weigh as much 150 kilograms (330 lbs), feeds on 25 varieties of bamboo and consumes as much as 9 to 14 kilograms (20 to 30 lbs) per day.

After identifying some 270 different microorganisms in panda dung obtained from Tokyo's Ueno Zoo, the researchers isolated five types of bacteria that were the most efficient at breaking down proteins and fats and that could reproduce easily even under high heat.

In one experiment, the researchers mixed the bacteria with 70 to 100 kilograms (lbs) of raw garbage, including vegetable stems, potatoes (raw and fried) and fish remains, and placed it in an industrial waste disposal machine. Seventeen weeks later, only 3 kilograms (6.6 lbs) of waste remained, while the rest had turned to water and carbon dioxide. With a digestive rate of up to 96%, the bacteria from panda excrement is significantly more effective than most commercial disposal bacteria, which has a digestive rate of around 80%.

In 2003, Taguchi also claimed it was possible to harvest about 100 liters (26 gallons) of hydrogen gas for every kilogram (2.2 lbs) of waste treated with panda poo. At the time, he was exploring the possibility of integrating a hydrogen fuel cell into a waste disposal unit to sell to food processing companies in Japan.

Interestingly, Taguchi is not the first Japanese scientist to receive an Ig Nobel Prize for excrement-themed research. In 2007, researcher Mayu Yamamoto won the chemistry prize for developing a method for extracting vanillin ? an ingredient in vanilla fragrance and flavoring ? from cow dung.

Taguchi is the 13th Japanese person to receive an Ig Nobel Prize since the awards were established in 1991. Previous prize-winning achievements from Japan include the invention of karaoke, which received the Peace Prize, and the Tamagotchi, which received the Economics Prize.

The annual Ig Nobel Prizes are meant to honor scientific achievements that ?first make people laugh, and then make them think,? according to the founders at science humor magazine Annals of Improbable Research.

‘Power Loader’ exoskeleton suit

30 Sep 2009

Power Loader exoskeleton suit by Activelink --

Engineers from Activelink, a Kyoto-based subsidiary of Panasonic, are hoping to turn science fiction into reality with a powerful robotic exoskeleton suit that gives its operator superhuman strength.


+ Video

The so-called "Power Loader" suit -- which takes its name from the fictional hydraulic exoskeleton suit appearing in the sci-fi classic "Aliens" (1986) -- is built on an aluminum-alloy frame and weighs 230 kilograms (500 lbs). Described as a "dual-arm power amplification robot," the exoskeleton suit is currently equipped with 18 electromagnetic motors that enable the wearer to lift 100 kilograms (220 lbs) with little effort. In addition, the Power Loader's simple, intuitive control system employs direct force feedback, allowing the operator to directly feel the movement of the robot while controlling it.

Not unlike the film version of the suit, which was used for carrying cargo around on spaceships and colonies, the Power Loader is being created to help humans with heavy lifting, particularly in construction and disaster relief operations.

The Power Loader is still in the development phase, but Activelink plans to have a marketable version of the suit by the year 2015.

Mechanical tumor, external heart, elastic cell

28 Sep 2009

Interactive media artist Mio I-zawa's "mechanical tumor" is a quivering hunk of fleshy, organic-looking material that expands and contracts depending on the amount of stress your computer is experiencing.


+ Video

Equipped with a series of motors and pneumatic actuators, the mechanical tumor pulsates gently when the CPU load is low. When the CPU load is high, the tumor's air compressor is activated, causing the lump of flesh to inflate.

Mechanical tumor, by Mio I-zawa --

The size of the tumor fluctuates according to the CPU utilization rate, giving the user a very tangible reading of the computer's stress level.

* * * * *

Other biologically inspired interactive devices by Mio I-zawa include "external heart," a squishy latex heart on wheels that beats and rolls around in sync with the user's pulse...

...and "elastic cell," a system of 46 soft pulsating cells that react to human touch in a complex, lifelike way.

Miruko: Wearable eyeball robot interface

24 Sep 2009

Miruko, wearable eyeball robot --

"Miruko," a wearable eyeball-shaped robot with a built-in camera and wi-fi capabilities, is designed to augment human perception by sensing and reacting to objects that cannot be seen with the naked eye.

In this video, Miruko's creators demonstrate how the robotic eyeball can be used as an interface for a virtual monster-hunting game played in a real-world environment.


+ Video

Worn on the player's sleeve, Miruko's roving eye scans the surroundings in search of virtual monsters that are invisible to the naked human eye. When a virtual monster is spotted, the mechanical eyeball rolls around in its socket and fixes its gaze on the monster's location. By following Miruko's line of sight, the player is able to locate the virtual monster and "capture" it via his or her iPhone camera.

Other skills, such as the ability to recognize and track specific faces or objects, suggest the Miruko robotic eyeball interface could be put to use in a variety of navigation, surveillance, and augmented reality entertainment applications.

Upstairs at Kitaro’s: Mini monster peepshow

24 Sep 2009

Several yōkai (Japanese folk monsters) inhabit the upstairs closet at the Kitarō Chaya teahouse in Chōfu (Tōkyō). Visible through peepholes in the door, these traditional monsters -- which are based on old folktales from across Japan -- appear in the popular GeGeGe no Kitarō manga/anime by Shigeru Mizuki, a long-time resident of Chōfu. (Click the [+] to enlarge each image.)

The Abura-sumashi (lit. "Oil Presser"), a folk monster from Kumamoto prefecture known for harassing mountain travelers, is believed to be the reincarnated spirit of an oil thief. Long ago, oil was essential for lighting and heating homes, and the divine punishment for people guilty of stealing this valuable commodity -- particularly from temples and shrines -- was reincarnation as a yōkai.

The Tsuchigumo is a large blood-sucking spider sometimes found under the floorboards of old houses. Details about this creature vary from tale to tale, and some theories suggest the monster's origins can be traced back to the exaggerated and embellished stories of encounters with mountain-dwelling people of ancient Japan, who were also referred to as "tsuchigumo" (lit. "ground spiders"). [More]

Kurage no Hinotama [+]

The Kurage no Hinotama is a jellyfish-shaped fireball (will-o-wisp) found near the sea. An account from the mid-18th century tells of a samurai who encountered one such ghostly flame on a warm breezy night at Zenshoji temple in Ishikawa prefecture. The man tried to slash the floating apparition with his sword, but to no avail. Unscathed by the attack, the fireball discharged a sticky red sap-like substance onto the man's face. [More]

In addition to the small collection of yōkai art upstairs, the Kitarō Chaya includes a gift shop and a tiny cafe that serves GeGeGe no Kitarō-themed drinks and snacks. The teahouse is located just outside the main entrance to Jindaiji temple, which is a 20-minute bus ride from Chōfu station (bus #34, north side of station, 200 yen).

Typographic town logos in hiragana/katakana

18 Sep 2009

Municipal flag, Japan --
[Typographic logo for Kamagaya (Chiba) spells town name in katakana]

Japanese town logos -- official symbols designed to communicate the identity of each municipality -- come in a vast array of shapes and colors. Many of these municipal symbols incorporate typographical elements (particularly kanji, hiragana, katakana, and Roman letters) into their designs. In most cases, the stylized characters are straightforward and easy to spot (even if you don't read Japanese), but sometimes you have to bend your eyes to see them. The more complex logos encode the name of the town into a puzzle-like symbol that begs to be deciphered. Here are a few typographic town logos that make clever use of hiragana and katakana characters. (The examples are arranged in Japanese alphabetical order and include a mixture of both alphabets.)
