Colorless inks that appear blue or green under ultraviolet light have been available for years, but a new ultraviolet ink developed by Hasegawa's team has added another dimension.
The team has created a red ink so that now it's possible to produce all the colors of the rainbow by combining the three basic colors.
The researchers are aiming at commercializing the newly developed ink.
If the ink is used on the white surface of identification cards, for example, information written on the surface can be shown when it is exposed to ultraviolet rays. Or, advertisements or interior designs can be displayed in the dark.
The colorful photos or pictures disappear if they are not exposed to the ultraviolet rays.
Hasegawa's team members developed the ink by using europium, a rare-earth element that emits weak lights of red color when exposed to ultraviolet rays."

"A research group focused on the development of artificial retina prototyped a system that can wirelessly supply power from an external source to an LSI in an artificial retina implanted in the eyeball.
The research group led by Mitsumasa Koyanagi, professor at graduate school of engineering, Tohoku University, presented the accomplishment at 2007 International Conference on Solid State Devices and Materials (SSDM), an international conference on semiconductors that was held from Sept. 18 to 21, 2007.
The latest system employs an electromagnetic induction type wireless power supply unit. The unit is equipped with a compact battery. It supplies power from the primary coil embedded in a lens of eyeglasses to the secondary coil in a crystalline lens serving as the lens for the eye by means of electromagnetic induction. Two major parts of the latest development were the secondary coil and the Schottky diode provided to rectify AC current supplied to the secondary coil to DC current."

The Eliica weighs in at 2400 kg (5291 lbs) and seats the driver and three passengers. The body of the four door car has a futuristic, bullet shape design which was tested in a wind tunnel. The front doors open forward and the rear doors open upward like wings. The car's platform contains 4 tracks of 80 batteries, which make for one third of the vehicle's cost. They currently require about 10 hours of recharging from empty to full charge, and can be easily charged off of a residential power grid.
The car has eight wheels enabling it to be closer to the ground for better traction. Each of the wheels has a 60 kW (80 hp) electric motor, giving a 480 kW (640 hp) eight wheel drive which can tackle all kinds of road surfaces. The four front wheels steer. The electric motors mean that the Eliica can deliver a smooth acceleration free from gear shifts of about 0.8 g. Each wheel contains a disc brake and employs a regenerative brake system to recover energy.
There are currently (as of 2005) two versions of the Eliica: a Speed model and an Acceleration model. The Speed model is made to challenge gasoline-based records and has a top speed of 370 km/h (230 mph) with a range of 200 km (125 miles). The Acceleration model is made for the street and has a top speed of 190 km/h (120 mph) with a range of 320 km (200 miles).
The estimated cost of development was in excess of US$320,000. Once the team receives corporate sponsorship, they plan to produce at least 200 units. As of early 2007, the projected pricetag was ¥30,000,000, or about $255,000 US."

Japan Carbon Offset, a nonprofit organization based in Tokyo, said it will begin a program to allow individuals as well as businesses to fight global warming by converting carbon dioxide emission rights into smaller lots for sale to investors. The program is the first of its kind in Japan, the organization said.
The program, expected to start later this year, will be carried out in cooperation with 16 companies, including retail giant Aeon Co., supermarket chain Seiyu Ltd., Sumitomo Mitsui Banking Corp. and the Bank of Tokyo-Mitsubishi UFJ, the group said Thursday.
Payments to buy products or services offered by the 16 businesses will be partially set aside to buy emission rights.
Until now, the precious metal has been an essential material in the electrode catalyst in conventional fuel cells for automobiles, said the company, which specialises in manufacturing small vehicles.
"This proprietary fuel cell technology provides numerous benefits, including resource conservation, low cost, high output, and safe and easy fuel handling," the company said in a statement.

The Japan Aerospace Exploration Agency, or JAXA, is calling the Kaguya project the most ambitious mission to the moon since the Apollo flights, more than three decades ago. The $479 million mission is also known as SELENE, or Selenological and Engineering Explorer.
The rocket carrying the three-ton orbiter took off into blue skies, leaving a huge trail of vapor over the tiny island of Tanegashima, about 1,000 km (620 miles) south of Tokyo, at 10:31 a.m. Friday (9:31 p.m. ET Thursday) as it headed out over the Pacific Ocean."

The Tokyo University inventors dubbed their method "surrogate broodstocking." They injected newly hatched but sterile Asian masu salmon with sperm-growing cells from rainbow trout — and watched the salmon grow up to produce trout.
The striking success, published in Friday's edition of the journal Science, is capturing the attention of conservation specialists, who say new techniques are badly needed. Captive breeding of endangered fish is difficult, and attempts to freeze fish eggs for posterity so far have failed.
The Japanese researchers' ultimate goal: Boost the rapidly dwindling population of bluefin tuna, a species prized in a country famed for its tuna appetite.
"We need to rescue them somehow," said Goro Yoshizaki, a Tokyo University marine scientist who is leading the research."

Given its compact size and low power, the chip can be applied to relatively small robots, the companies said."

One of the cars that will make its worldwide debut is the i MiEV SPORT. Based on the i MiEV, the new vehicle enhances the driving experience. The i MiEV is an electric vehicle based on the platform of the light car i, which drives the rear wheels by a motor. In contrast, the i MiEV SPORT employs, in addition to the rear motor, in-wheel motors at left and right sides in the front to enhance maneuverability.
To increase the utilization efficiency of energy, the i MiEV SPORT is equipped with a photovoltaic generator attached on the roof and a power-generating fan inside the front grill. The photovoltaic generator has a generation efficiency of 13%, and recharges the battery while the car is parked.When lit by the sun for about 1 week, an energy corresponding to 10% of the battery capacity (equivalent to a cruising distance of 20 km) can be recharged. When the car is slowing down, the fan inside the front grill is rotated for the power generation."

"Mapping the great network that is the internet was never going to be an easy task. There would have to be as many connections as there are in the human brain. But for a group of web architects based in Japan, it is worth a go.
Modelled on the fiendishly complex Tokyo Metro map, the latest Web Trend Map (the 2007/V2 version) organises some of cyberspace's movers and shakers into an easy-to-read chart. Plotted by the Japanese firm Information Architects (IA), each line on the map represents a theme, be it news (green), tools (pink) or the brown Chinese line, which IA calls the "second internet", after the country's efforts to censor much of the content freely available in the West."

"Bandai's newest high-tech toy? A translucent robot modeled after real cockroaches. This little thing has six legs, a touch sensor that tells it to change directions when it hits a wall, a micro monitor that makes it vibrate like a cell phone, and a mic sensor that lets it scuttle away when you make loud noises.
After experimenting with several different bugs, the creators decided that the cockroach's movements and speed were the most compatible with battery efficiency and design. You can also get models with bodies resembling ladybugs, but they're still going to move like roaches.
The Hex Bug comes out in mid-September and will retail for about $15/each."

article from TokyoMango.com"From the "idea is better than the actual product" department, this chair answers the question, "Why get a desk and a chair when you can just get a chair-desk?" Even though it's not the sleekest implementation we've ever seen, we really like the concept; less stuff is better than more stuff, right? Conceived in Japan, where living space is at a premium, it might make sense for us bloggers, too; rather than hunching over our laptops on the couch or lounging in bed in our pajamas, this could be a major upgrade to the "home office." Looks like it's only available in Japan for now; we'll have to settle for the flexible Trey chair. ::Thanko Chair/Desk (site in
