A map of the genome for every home

19 Apr 2006

Japan?s Ministry of Education, Culture, Sports, Science and Technology has published a map of the human genome for the general population that it aims to distribute to households across the country. A total of 40,000 maps are being provided to primary, middle and high schools nationwide, and about 50,000 copies are being supplied to science museums around the country, where they will be distributed to the public on a first-come, first-served basis.

Human genome map

The map includes the names and locations of about 1% of the 26,800 genes that make up the human genome. Details and illustrations help explain genes that hit close to home, such as the one that determines your ability to metabolize alcohol and the one that produces collagen. PDF versions of the map are available for download (large or small), and an interactive Flash version is here.

Akihabara maids want your blood

24 Mar 2006

Akiba maid gives hand massage to blood donorAs the number of willing blood donors in Japan continues to decline, the Japanese Red Cross is stepping up efforts to reverse the trend by offering a unique range of services at blood donation sites.

These services include hand massages by Akihabara "maids," hair/scalp health checks, and palm readings. The Japanese Red Cross has organized the services in part to increase the number of repeat donors, considered critical in combating the declining number of blood donors resulting from the aging of the population.

At the Akiba Blood Donation Room near JR Akihabara station, a young woman wearing a white apron over a dark green one-piece dress greets a donor as he enters. "Welcome back, my lord," she says. After the man is finished with his blood draw, she gives him a 10-minute hand massage. The maid, who is an employee at a local foot care salon, was enlisted by the Red Cross in its attempt to capitalize on the local "maid cafe" boom. The Akiba Blood Donation Room is offering this service until the end of March.

A spokesman for the Akiba Blood Donation Room says there were initial concerns about whether the service went too far. But in an attempt to boost the number of weekday donors -- whose numbers are less than half those of their weekend counterparts -- they decided to go ahead and offer the special service to the first 10 people on Mondays, Wednesdays and Thursdays.

Some donors are surprised to encounter a young woman dressed as a maid. But one donor, after giving blood, remarked, "It?s very 'Akiba.' It's fun.?

Several years ago, the Shinjuku station (east exit) blood donation site began offering manicures and hair care advice provided by specialists from the Japan Hair Science Association. Now, those services are firmly established. After the Yurakucho blood donation site began offering tarot card and palm readings last year, many repeat donors began scheduling their visits to coincide with days that fortune-telling services were offered.

Fun aside, the Japanese Red Cross sees the declining number of blood donors as a serious problem. In 1993, 7.2 million people gave blood in Japan, compared to 5.6 million in 2003. Donors under 30 years of age, who made up 47% of the total in 1993, fell to 35% of the total in 2003.

Over the next five years, the Red Cross hopes to increase the number of repeat donors (who give more than once a year) from the current number of 930,000 to 1.2 million. They will begin offering other services to people who register for membership on the "repeater" homepage, such as free health consultations from doctors and health counselors at each blood center.

The demand for blood fluctuates with the occurrence of major disasters and accidents. By boosting the number of weekday donors and repeaters, the Red Cross hopes to secure a stable supply of safe blood.

RI-MAN revisited

14 Mar 2006

RI-MANMore details about RI-MAN, the soft-skinned robot, were revealed in a press release issued by RIKEN yesterday.

RI-MAN is the world's first robot designed for lifting and carrying humans. A variety of sensors, including flexible tactile sensor sheets, provide RI-MAN with a sense of vision, hearing, touch, and smell. These senses help RI-MAN perform tasks such as locating people who are calling out to it, responding to spoken commands, carefully lifting those who need lifting, and checking the sanitary condition of the person it is carrying. RI-MAN is able to integrate a wide range of sensory data to adapt to changes in the environment.

The robot is also equipped with 19 motors, controlled by a system of hierarchical distributed processing that is modeled after the nervous system found in biological organisms. This "nervous system" -- a network of what RIKEN calls C-CHIPs -- integrates sensor data processing with motor control to provide RI-MAN the autonomy needed to respond quickly to changes in the environment. The head has 3 degrees of freedom, each arm has 6, the waist has 2, and the base (which acts as RI-MAN?s legs) has 2. Safety-related technology, including safety circuits and soft skin and joints designed to prevent injury, are incorporated into RI-MAN?s design.

Still in the initial testing phase, RI-MAN is currently practicing with dolls that weigh about 12 kg (26 lbs). Researchers plan to increase the weight of the practice dolls over time, with the aim of achieving the ability to lift human adults in 5 years. Researchers will continue working to upgrade RI-MAN's sensors and data processing skills to improve adaptability. The aim is to create a robot with the physical power needed for heavy lifting and the reasoning skills needed for operating in places like people's homes. RIKEN says that with these skills, RI-MAN can be put to work in nursing and rehabilitation, in furniture moving, or in any other job that requires muscle.

RI-MAN, the soft-skinned robot

28 Feb 2006

RI-MAN, an autonomous lifestyle-support robot developed at RIKEN's Bio-Mimetic Control Research Center (Nagoya, Japan), now has soft skin. If put to work in care facilities, RI-MAN's soft arms and chest will enable it to perform delicate work that present-day robots are not allowed to do, such as lifting patients up into its arms.

RI-MAN, the soft-skinned robot

The robot, which is 158 cm (5 ft 2 in) tall and weighs about 100 kg (220 lbs), consists of a humanoid upper body that sits atop a wheeled base. A 5-mm layer of silicone covers most of the upper body, including the face and chest. The skin sinks in slightly when pressed, giving it a resilient, supple feeling. Under the layer of silicone are 320 pressure sensors that enable RI-MAN to self-adjust the softness as needed.

Research team leader Zhiwei Luo says, "We may see commercial applications of this technology in as early as five years."
