Science fiction in the real world

From KurzweilAI.net — a city of the future is going up in Abu Dhabi, and “Fantastic Voyage” gets one step closer to reality.

Building the Zero-Emissions City
Technology Review, May 8, 2008

Construction has started on a city in Abu Dhabi that will house 50,000 people and 1,500 businesses but use extremely little energy, and what it does use will come from renewable sources.

The city, which is expected to cost $22 billion, will implement an array of technologies, including thin-film solar panels that serve as the facades and roofing materials for buildings, ubiquitous sensors for monitoring energyuse, and driverless vehicles powered by batteries that make cars unnecessary. The city’s founders hope that it will serve as a test bed for a myriad of new technologies being proposed to reduce greenhouse-gas emissions.

Nanoworms target tumors
KurzweilAI.net, May 8, 2008

Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized “nanoworms” that can cruise through the bloodstream without significant interference from the body’s immune defense system and home in on tumors, reminiscent of the science fiction movie, Fantastic Voyage.

The scientists constructed their nanoworms from spherical iron oxide nanoparticles that join together, like segments of an earthworm, to produce tiny gummy worm-like structures about 30 nanometers long. Their iron-oxide composition allows the nanoworms to show up brightly in MRI diagnostic devices.

Using nanoworms, doctors should eventually be able to target and reveal the location of developing tumors that are too small to detect by conventional methods. Carrying payloads targeted to specific features on tumors, these microscopic vehicles could also one day provide the means to more effectively deliver toxic anti-cancer drugs to specific tumors, organs and other sites in the body, in high concentrations without negatively impacting other parts of the body.
