Car Could Turn Roads Into Express-Yourself Lanes Link Four inventors working for Toyota in Japan have won a patent for a car that they say can help drivers communicate better by "glaring angrily at another car cutting through traffic as well as appear to cry, laugh, wink or just look around." In the patent they have taken out, they write, "As traffic grows heavier and vehicle use increases, vehicles having expression functions, such as crying and laughing like people and other animals do, could create a joyful, organic atmosphere rather than the simple comings and goings of inorganic vehicles." The car comes with a computer and software system that detects road and vehicle conditions like steering angle, braking or speed. Drivers or passengers can also enter information about their moods into the system. But it is the car that expresses an emotional reaction. [ permanent link to this entry ]
Mexican Attorney General Gets Security Microchip Implant in Arm Link Mexico's Attorney General Rafael Macedo de la Concha said he had a non-removable microchip implanted in his arm as a security measure to track him throughout Mexico and to give him access to a crime data bank. The chip can't be removed, but will be deactivated after Macedo's term as attorney general expires, he said. About 160 Mexican officials will carry the microchip, according to the Mexico City daily El Universal. [ permanent link to this entry ]
Heated Nanoshells Kill Cancer Cells Link US researchers are hailing a non-invasive treatment which destroys tumours by heat a success after the first phase of animal testing. According to the team from Rice University and its licensee, Nanospectra Bioscience, the method has eradicated tumours in mice and does not affect healthy tissue. The technique relies on tiny gold-coated particles called nanoshells which, when injected into the bloodstream, selectively accumulate in tumours. By varying the size of the core and the thickness of the gold shell, the team tailors the nanoshell to convert near-infrared light into heat. The heating is said to be localized and does not affect healthy tissue close to the tumour. [ permanent link to this entry ]
